Answer: it would take them 40/13 hours

Step-by-step explanation:

If Naomi were to paint her living room alone, it would take 5 hours. it means that the rate at which she paint her living room alone is 1/5

Her sister Jackie could do the job in 8 hours. it means that the rate at which Jackie paint the living room is 1/8

If they work together, they would work simultaneously and their individual rates are additive. This means that their combined working rate would be

1/5 + 1/8 = (8 + 5)/40 = 13/40

Assuming it takes t hours for both of them to clean the room working together, the working rate per hour would be 1/t. Therefore,

13/40 = 1/t

t = 40/13 hours

Answer:

[tex]D(t)=100(0.4)^t[/tex]

Step-by-step explanation:

The temp is 100 at time t = 0

After 1 sec, the temp difference would be:

[tex]100-(\frac{100-60}{100})[/tex]

After 2 sec, the temp difference would be:

[tex]100-(\frac{100-60}{100})^2[/tex]

Similarly for 3 seconds, 4 seconds etc.

We notice that the parenthesis part is 40% of it, so we can also write:

100(40%)^t,

where

t is the time

40% can be written as 40/100  = 0.4

SO, the function is:

[tex]d(t)=100(0.4)^t[/tex]

Answer:

[tex]D(t)=100*0.4^t[/tex]

Step-by-step explanation:

Initially, the difference between the rod's and the water's temperatures is 100°

i.e D(t)=100 When t=0

After 1 seconds, the temp drops by 60%.

Therefore, the new value of D will be the old value multiplied by (100-60)%.

D(1)=100 X (100%-60%) = 100*0.4

After 2 seconds, the temp difference would be:

D(2)=100*0.4*0.4= [tex]100*0.4^2[/tex]

We notice that for any t, the percentage at which the difference is reduced is raised to the power of t.

Therefore, temperature difference in degrees Celsius, D(t), t seconds after the rod was plunged into the water is given as:

[tex]D(t)=100*0.4^t[/tex]

Probability, P(getting 2 toppings)= 0.1984

Step-by-step explanation:

Probability, P(1 toppings)= 1/7

Probability P of getting a particular topping is q = 1 - P = 1 - 1/7 = 6/7

Probability of( getting 2 toppings)= 7!/(2!5!)(1/7)^2 × (6/7)^5

P(getting 2 toopings)= (5040/240) × (0.020)× (0.4627)

P(getting 2 toppings)= 21 × 0.00948 = 0.1984

Leah asked her dance students to hand out at least 10 flyers for their upcoming dance recital and construct a histogram to display the data.

In this question, Leah asked her dance students to each hand out at least 10 flyers for their upcoming dance recital. Then, she constructed a histogram to display the number of recital flyers handed out by the students.

To solve this, Leah can tally the number of students who handed out a specific number of flyers and create intervals on the x-axis of the histogram to represent the number of flyers. The height of each bar in the histogram will represent the number of students who handed out the corresponding number of flyers. By constructing the histogram, Leah can visualize the distribution of the number of flyers handed out by her dance students.

Final answer:

The question is related to Mathematics, specifically the creation and analysis of histograms, frequency tables, and probability distributions, often used in statistics to visualize and interpret various sets of data.

Explanation:

The student's question falls under the subject of Mathematics, specifically related to statistics and data analysis. In this instance, various exercises are mentioned where the creation and interpretation of histograms are central. These exercises are multifaceted, requiring students to compile data, calculate statistical measures such as means and probabilities, and graphically represent data using histograms and other charts.

For example, when Leah asks her dance students to hand out flyers, she is gathering data that can be represented in a histogram to visualize the distribution of flyers handed out. Similarly, the ballet instructor's data on retention rates can form a probability distribution. When Jill delivers flyers for her yard sale, her travel distances and times could be used to create a time series graph.

Histograms, frequency tables, and probability distributions are tools used in these exercises to better understand the data collected, whether it's related to dance flyer distribution, car sales, or family size among classmates.

Answer: you bought 7 bottles of orange juice and 8 bottles of apple juice.

Step-by-step explanation:

Let x represent the number of 1-gallon bottles of orange juice that you bought.

Let y represent the number of 1-gallon bottles of apple juice that you bought.

You bought 15 1 gallon bottles of orange juice and apple juice for school breakfast. This means that

x + y = 15

The apple juice was on sale for $1.50 per gallon bottle. The orange juice was two dollars per gallon bottle. You spent $26. This means that

2x + 1.5y = 26 - - - - - - - - - - - - -1

Substituting x = 15 - y into equation 1, it becomes

2(15 - y) + 1.5y = 26

30 - 2y + 1.5y = 26

- 2y + 1.5y = 26 - 30

- 0.5y = - 4

y = - 4/ - 0.5

y = 8

x = 15 - y = 15 - 8

x = 7

To find the number of virus particles after 3 days, substitute x=3 into the given polynomial. The number of virus particles, in billions, after 3 days is approximately 48.37 billion.

To find the number of virus particles after 3 days, substitute x=3 into the polynomial:

y = -0.73(3)^4 + 3.1(3)^3 + 26.5

Calculating this expression:

y = -0.73(81) + 3.1(27) + 26.5 = -59.13 + 81 + 26.5 = 48.37

Therefore, the number of virus particles, in billions, after 3 days is approximately 48.37 billion.

The area of the given rectangle is of the standard form option 1.[tex]2x^{2} + 3x - 20[/tex].

Step-by-step explanation:

Step 1:

The parameters needed to determine the area of a rectangle are the base length and the width.

The base length of this rectangle is [tex]2x-5[/tex] units while its width is [tex]x+4[/tex] units.

The area of a rectangle is determined by multiplying the base length with the width.

Step 2:

The area of the rectangle [tex]= (length)(width).[/tex]

Here length is [tex]2x-5[/tex] units and the width is [tex]x+4[/tex] units.

The area of the rectangle[tex]= (2x-5)(x+4) = 2x^{2} + 8x -5x-20 = 2x^{2} + 3x - 20.[/tex]

So the area of the given rectangle is of the standard form [tex]2x^{2} + 3x - 20[/tex] which is the first option.

To find the area of the rectangle, we need to multiply the expressions for the lengths of its sides. The sides are given as [tex]\(2x - 2\) and \(x + 4\).[/tex]

First, write the expressions for the sides of the rectangle:

- One side is[tex]\(2x - 2\)[/tex]

- The other side is[tex]\(x + 4\)[/tex]

To find the area, multiply these two expressions:

[tex]\[(2x - 2)(x + 4)\][/tex]

Use the distributive property (also known as the FOIL method for binomials) to expand this product:

[tex]\[(2x - 2)(x + 4) = 2x(x) + 2x(4) - 2(x) - 2(4)\][/tex]

Simplify each term:

[tex]\[= 2x^2 + 8x - 2x - 8\][/tex]

Combine like terms:

[tex]\[= 2x^2 + 6x - 8\][/tex]

So, the polynomial expression in standard form representing the area of the rectangle is:

[tex]\[2x^2 + 6x - 8\][/tex]

Given the options:

- 2x^2 + 3x − 20

- 2x^2 + 13x − 1

- 2x^2 + 13x − 20

- 2x^2 + 3x − 1

None of these options exactly match our result of [tex]\(2x^2 + 6x - 8\),[/tex] indicating a potential error in the problem statement or options provided. The correct simplified polynomial expression for the area, based on the given side lengths, is[tex]\(2x^2 + 6x - 8\).[/tex]

  5 × 2 = 10

Cathy must fill the 2-cup jar 5 times to transfer a total of 10 cups.

Final answer:

To fill a 10-cup bucket using a 2-cup jar, Cathy must scoop water from the pond 5 times, as 10 divided by 2 equals 5.

Explanation:

The question is how many times Cathy needs to scoop water from the pond with a 2-cup jar to fill her 10-cup bucket.

To find the answer, we simply divide the total capacity of the bucket by the capacity of the jar. So, the calculation would be:

Calculate the total number of cups needed: 10 cups (capacity of the bucket).

Calculate the number of cups per scoop: 2 cups (capacity of the jar).

Divide the total number of cups by the number of cups per scoop: 10 cups/ 2 cups per scoop

= 5 scoops.

Cathy needs to scoop water from the pond 5 times to fill her 10-cup bucket.

Answer:

The new mean = 3 × (the old mean) = 150

The new standard deviation is also = 3 × (The old standard deviation) = 15

Step-by-step explanation:

µ = 50 and σ = 5

The mean is the sum of variables divided by the number of variables.

Mean = (Σx)/N = µ = 50

x = each variable

N = number of variables

If each variable changed to 3x

Mean becomes

Mean = (Σ(3x))/N = 3 (Σx)/N = 3 × µ = 3 × 50 = 150.

The standard deviation is the square root of variance. And variance is an average of the squared deviations from the mean.

The standard deviation measures the rate of spread of the data set around the mean.

Standard deviation = σ = √[Σ(x - µ)²/N]

x = each variable

µ = mean

N = number of variables

If each variable changed to 3x

Recall µ changed to 3µ

Standard deviation = σ = √[Σ(3x - 3µ)²/N]

σ = √[Σ 3² (x - µ)²/N] = √[(3²)Σ(x - µ)²/N] = 3×√[Σ(x - µ)²/N] = 3 × σ = 3 × 5 = 15

If every score is multiplied by 3, it is logical to reason that the average of the new set of numbers also is 3× the old average.

And the new set of numbers spread out similarly around this new mean, only that the new space of spread is now 3× the old one.

When every score in a population is multiplied by a constant, both the mean and the standard deviation are multiplied by that constant. So, in the given example, the new mean would be 150 and the new standard deviation would be 15.

In mathematics, when every score in a population is multiplied by a constant, both the mean (µ) and the standard deviation (σ) are also multiplied by that constant.

So, if every score in a population with µ = 50 and σ = 5 is multiplied by 3, the new mean (µ_new) would be 50 * 3 = 150, and the new standard deviation (σ_new) would be 5 * 3 = 15.

b) Percentage of households has two children under the age of 5 ,

= [tex]\frac{14}{50}[/tex] x 100

Final answer:

To calculate the percentage of households with two children under the age of 5, divide the frequency of 2 by the total number of households and multiply by 100.

Explanation:

To calculate the percentage of households with two children under the age of 5, we need to find the relative frequency of 2 in the given data. The relative frequency is calculated by dividing the frequency of 2 by the total number of households, which is 50 in this case. The frequency of 2 is 0.06, so the relative frequency of 2 is 0.06/50 = 0.0012. To convert it to percentage, we multiply by 100, so the percentage of households with two children under the age of 5 is 0.0012 * 100 = 0.12%.

Answer:

y will increase if x is increased,

y will decrease if x is decreased.

Step-by-step explanation:

1/F=1/X+ 1/Y

1/F-1/X=1/Y

X-F/FX=1/Y

FX/X-F=Y

Rearranging, Y=FX/X-F

So this is the function in terms of X, and F is just a constant

Therefore, the function becomes Y=65X/X-65

Explanation:

y = focusing distance

x = distance from lens

Focusing distance y will increase if the object x moves far away from the lens i.e. x is increased,

Similarly, focusing distance y will decrease if the object x moves closer and closer to the lens i.e. x is decreased.

An asymptote is a function that mimics a curve f(x) as x approaches infinity.

A vertical asymptote, however, cannot be crossed in a function.  Remember that a function cannot have multiple y values for a given x value, hence the vertical line test for a function.  If a function crossed a vertical asymptote and then went back to it, then it would have to go back over itself as it becomes arbitrarily close to the asymptote. Therefore, it is not possible to cross a vertical asymptote.

The focal point, F, the object distance from the lens, X, and the image distance from the the lens, Y, vary according to the lens formula

1. The value of the focusing distance, Y, is negative and increases in

magnitude, when X < 65, and positive and decreasing in magnitude when

X > 65, the line X = 65 is a vertical asymptote.

2. When X > 65, the value of Y is positive and increasing as the object

moves closer to the lens. At X = 65, there is no image when 0 ≤ X < 65, the

value of Y is negative and increasing towards 0.

3. A vertical asymptote is a discontinuity, where the function is not defined

Reasons:

Known;

[tex]\dfrac{1}{F} = \dfrac{1}{X} + \dfrac{1}{Y}[/tex]

Where;

F = The focal length

X = Object distance from lens

Y = Location of film = Image distance from lens

(a) Given that F = 65, we have;

[tex]\dfrac{1}{65} = \dfrac{1}{X} + \dfrac{1}{Y}[/tex]

[tex]\dfrac{1}{65} - \dfrac{1}{X} = \dfrac{1}{Y}[/tex]

[tex]Y = \dfrac{65 \cdot X}{X - 65}[/tex]

Given that 65·X > X - 65 When X > [tex]-\dfrac{65}{64}[/tex], we have;

As X is increased, Y is decreases, with the rate of decrease reducing as the

value of X gets larger.

(b) As the object moves closer to the lens, when X > 65, the value of Y

increases, at X = 65, the value of Y is infinity, which is a vertical asymptote,

as the object moves closer, the value of Y becomes negative, with the

value increasing (becoming less negative) and when X = 0, Y = 0

3. It is not possible to cross the asymptote because the function has a

discontinuity at the asymptote, which represent the point where the image

is at infinity, such that giving that the distance of the image increases as X

approaches the asymptote, crossing the asymptote results in the image

located further than infinity (which is impossible).

Answer:

1350

Step-by-step explanation:

Initially 90 squirrels were tagged out of a total population of x squirrels.

Similarly, 42 squirrels out of a sample of 630 squirrels had tag

We can use ratio equality to find the total population x.

42:90=620:x

[tex]\frac{42}{90} =\frac{630}{x}[/tex]

Cross multiplying

42 X x = 630 X 90

Dividing both sides by 42

[tex]x=\frac{630 X 90}{42} \\=1350[/tex]

The total number of squirrels in the city park is 1350.

The total number of squirrels in the park is approximately 1350.

To estimate the total squirrel population in the park, we can use the Lincoln-Petersen method, which is a mark-recapture technique. The formula for this method is:

[tex]\[ N = \frac{(M \times n)}{m} \][/tex]

Given the data:

- ( M = 90 ) (the number of tagged squirrels),

- ( n = 630 ) (the total number of squirrels counted in the second sample),

- ( m = 42 ) (the number of tagged squirrels found in the second sample).

Plugging these values into the formula, we get:

[tex]\[ N = \frac{(90 \times 630)}{42} \] \[ N = \frac{56700}{42} \] \[ N = 1350 \][/tex]

Therefore, the total number of squirrels in the park is estimated to be 1350.

We're trying to figure out how far the dolphin travels with each kick. The dolphin starts at an elevation of -16 3/4 feet and ends up at an elevation of -5 1/4 feet. In other words, what can we add to -16 3/4 to get -5 1/4?

The elevation is our variable (x). The dolphin kicks 5 times to get from point a to point b. So we should add 5x to -16 3/4 to get -5 1/4. This equation will solve for the length in feet traveled per kick. Our equation is now:

5x + -16 3/4 = -5 1/4

Adding a negative is the same thing as subtracting a positive, so our final equation is:

5x - 16 3/4 = -5 1/4

If we want to solve this:

5x - 16.75 = -5.25

5x = 11.5

x = 2.3 feet per kick

Answer:

Therefore the required polynomial is

M(x)=0.83(x³+4x²+16x+64)

Step-by-step explanation:

Given that M is a polynomial of degree 3.

So, it has three zeros.

Let the polynomial be

M(x) =a(x-p)(x-q)(x-r)

The two zeros of the polynomial are -4 and 4i.

Since 4i is a complex number. Then the conjugate of 4i is also a zero of the polynomial i.e -4i.

Then,

M(x)= a{x-(-4)}(x-4i){x-(-4i)}

      =a(x+4)(x-4i)(x+4i)

      =a(x+4){x²-(4i)²}      [ applying the formula (a+b)(a-b)=a²-b²]

      =a(x+4)(x²-16i²)

      =a(x+4)(x²+16)      [∵i² = -1]

      =a(x³+4x²+16x+64)

Again given that M(0)= 53.12 . Putting x=0 in the polynomial

53.12 =a(0+4.0+16.0+64)

[tex]\Rightarrow a = \frac{53.12}{64}[/tex]

      =0.83

Therefore the required polynomial is

M(x)=0.83(x³+4x²+16x+64)

Answer:

198,400,000

Step-by-step explanation:

Total Approximate Number of Residents in the United States = 320 million

38 per cent of the total number of residents live in the South

That means, as a percentage, 100%-38%=62% live in other areas of the Unjted States.

[tex]62 \% of 320 million[/tex] = [tex]\frac{62}{100}X320000000[/tex]=198,400,000.

Therefore a total of about 198,400,000 live in other areas of the United States.

Answer:

The answer to your question is 1.59 km

Step-by-step explanation:

Data

Sign 54 km or 34 mi

1 mi = ? km

Process

1.- Use proportions and cross multiplication to find the answer

               54 km ----------------- 34 mi

                 x   km ----------------    1 mi

                 x = (1 mi x 54 km) / 34 mi

-Simplification

                 x = 54 km / 34

-Result

                x = 1.59 km

2.- Conclusion

1 mile is equivalent to 1.59 km
