Answers

Answer 1
Answer:

The translation of a phrase into a variable expression is given by:

                            b+7

Step-by-step explanation:

The letter ' b ' is used to name the variable.

The total number of slices of bread used for the sandwiches and the 7 still left in the loaf.

Let b be the total number of slices that were used for the sandwiches.

and also 7 are still left in the loaf

The total number of slices of bread= Number of slices used fro sandwich+Left over

                    Hence, the expression is:

                                 b+7

Enter your answer, as an inequality, in the box

Answers

The solution to the inequality -32 > -5 + 9x is x > -3.

To solve the inequality -32 > -5 + 9x, we'll isolate the variable x by first getting rid of the constant term (-5) on the right side.

1. Add 5 to both sides:

  -32 + 5 > 9x

  -27 > 9x

2. Divide both sides by 9 to solve for x:

  -27/9 > x

  -3 > x

Therefore, x is greater than -3. In interval notation, this can be written as (-∞, -3). In inequality notation, it's expressed as x > -3.

We started by isolating the variable x by adding 5 to both sides, then divided by 9 to solve for x. Remember, when dividing or multiplying by a negative number, the direction of the inequality sign flips. Thus, the final solution is x > -3.

Seascapes rent small fishing boats for a day-long fishing trips. each boat can carry only 1200 lb of people and gear for safety reasons. Assume the average weight of a person is 150 lb. each group will require 200 pounds of gear for the boat plus 10 lb of gear for each person.

A) create any quality describing the restrictions on the number of people that can possibly fit in a rented boat.

B) several groups of people wish to rent a boat Group one has 4 people group two has 5 people group three has 8 people. Determine which of the groups, if any, can safely run a boat what is the maximum number of people that may rent a boat.

Answers

A. We are given that each person weighs 150 lb, each gear per person weighs 10 lb, and a total of 200 pounds of gear for the boat itself.

Since each person only carries one gear, therefore total weight per person in 160 lb (weight of person + weight of gear).

So let us say that x is the number of persons, the inequality equation is:

 

160 x + 200 ≤ 1200

 

 

B. There are three groups that wish to rent the boat.

> Solve the inequality equation when x = 4

160 (4) + 200 ≤ 1200

840 ≤ 1200           (TRUE)

 

> Solve the inequality equation when x = 5

160 (5) + 200 ≤ 1200

1000 ≤ 1200         (TRUE)

 

> Solve the inequality equation when x = 8

160 (8) + 200 ≤ 1200

1480 ≤ 1200         (FALSE)

 

So only the 4 people group and 5 people group can safely run the boat.

 

 

C. Find the maximum number of people that may safely use the boat, solve for x:

 

160 x + 200 ≤ 1200

160 x ≤ 1000

x ≤ 6.25

 

Therefore the maximum number of people that can safely use the boat is 6 people.

A mathematical inequality is created to determine that a maximum of 6 people can rent a boat based on the safety weight limit of 1200 lb. Of the groups provided, only groups with 4 or 5 people can safely rent the boat, while the group with 8 people cannot due to exceeding the weight limit.

To determine the restrictions on the number of people that can possibly fit in a rented boat given the safety weight limit, we start by creating an inequality. Let p represent the number of people, then the total weight of the people is 150 lb times p, and the total gear weight is 200 lb for the boat plus 10 lb per person. The inequality can be represented as:

150p + 10p + 200 \<= 1200

Simplifying the inequality gives us:

160p \<= 1000

Dividing both sides by 160:

p \<= 1000 / 160

p \<= 6.25

Since we cannot have a fraction of a person, the maximum number of people allowed is 6.

For part B, we evaluate if the groups mentioned can safely rent a boat:

Group 1 (4 people): 150(4) + 10(4) + 200 = 840 lb \<= 1200 lb - they can rent.

Group 2 (5 people): 150(5) + 10(5) + 200 = 1000 lb \<= 1200 lb - they can rent.

Group 3 (8 people): 150(8) + 10(8) + 200 = 1480 lb > 1200 lb - they cannot rent as it exceeds the limit.

The maximum number of people who may rent a boat based on the given restrictions and average weights is 6 people.

Find the difference quotient and simplify your answer. f(x) = 7x − x2, f(7 + h) − f(7) h , h ≠ 0

Answers

whatever is inside of the ( ), simply plug that digit into the x-values for f(x)
So: f(x) = 7x - x^2, and f(7+h) - f(7)
= [7(7+h) - (7+h)^2] - [7(7) - (7)^2]
= [49+7h - 49+14h+h^2] - [49-49]
= 49-49 + 7h+14h + h^2 = h^2 + 21h =
h (h+21), h (h+21) = 0
h=0... But it stated h cannot = 0
So h+21 = 0, h = -21
Final answer:

The difference quotient for the function f(x) = 7x - x² is (7h - h²) / h.

Explanation:

The difference quotient is used to find the rate at which a function changes over a small interval. To find the difference quotient for the given function f(x) = 7x − x², we substitute f(7 + h) and f(7) into the formula: [f(7 + h) - f(7)] / h. Simplifying the expression, we get [(7(7 + h) - (7 + h)²) - (7(7) - 7²)] / h. Expanding and simplifying further, we have [(49 + 7h - h²) - (49 - 49)] / h, which becomes (7h - h²) / h.

A box measures 2 cm x 0.09 m x 20 mm. what is its volume in cubic centimeters?

Answers

Final answer:

To find the volume of the box, convert all dimensions to centimeters and then use the formula length x width x height. The volume is 36 cm³.

Explanation:

To calculate the volume of a rectangular box with dimensions in different units, we must first convert all dimensions to the same unit of measure. In this case, we will convert meters and millimeters to centimeters:

0.09 m = 0.09 * 100 cm = 9 cm

20 mm = 20 / 10 cm = 2 cm

Now we can calculate the volume using the formula for the volume of a rectangular box, which is length × width × height:

Volume = 2 cm × 9 cm × 2 cm = 36 cm³

How to find the elements of each set?

We need to find all the values of x that meet the given restrictions for each set.

a) Here we know that x is a real number and we must have:

x^2  = 1

Solving for x:

x = ±√1 = ±1

Then this set is:

{-1, 1}

b) Here x is a positive integer smaller than 12, this is just:

{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11}

c) In this case x is a square number, and it must be smaller than 100, so let's find all the square values smaller than 100.

1^2 = 12^2 = 43^2 = 94^2 = 165^2 = 256^2 = 367^2  = 498^2 =  649*9 = 8110*10 = 100  (from this onwards, the squares don't meet the criteria).

Then this set is:

{1, 4, 9, 16, 25, 36, 49, 64, 81}

d) Here x must be an integer, such that x^2 = 2

Solving the equation we get:

x = ±√2

But √2 is an irrational number, so there is no integer number that meets this restriction, this means that we have an empty set, this is written as:

{∅}.

Suppose that there is a positive correlation between the variables k and I. If l is 75when k is 7, which of these is most likely to be the value of l when k is 14.

Answers

positive correlation varies jointly

I = ck
75 = c(7)
75/7 = c
10.71 = c

I = (10.71)k
I = (10.71)(14)
I = 150

Answer:

l = 150

Step-by-step explanation:

The numbers k and have a positive correlation, to know the correlation between these two variables we have to use the values they give us:

When l = 75 the k = 7

The correlation between the two numbers is division. So this can be written as:

correlation: I = 75/7 k

So if we substitute k=14

l = 75/7 * 14

l = 150

We can also get this number by rule of three:

75/7 = x/14

75/7 *14 = l

1050/7 = l

150 = l

Average precipitation for the first 7 months of the year, the average precipitation in toledo, ohio, is 19.32 inches. if the average precipitation is normally distributed with a standard deviation of 2.44 inches, find these probabilities.

Answers

Part A:

The probability that a normally distributed data with a mean, μ and standard deviation, σ is greater than a given value, a is given by:

[tex]P(x\ \textgreater \ a)=1-P(x\ \textless \ a)=1-P\left(z\ \textless \ \frac{a-\mu}{\sigma}\right)[/tex]

Given that the average precipitation in Toledo, Ohio for the past 7 months is 19.32 inches with a standard deviation of 2.44 inches, the probability that a randomly selected year will have precipitation greater than 18 inches for the first 7 months is given by:

[tex]P(x\ \textgreater \ 18)=1-P(x\ \textless \ 18) \\ \\ =1-P\left(z\ \textless \ \frac{18-19.32}{2.44}\right) \\ \\ =1-P(z\ \textless \ -0.5410) \\ \\ =1-0.29426=\bold{0.7057} [/tex]



Part B:

The probability that an n randomly selected samples of a normally distributed data with a mean, μ and standard deviation, σ is greater than a given value, a is given by:

[tex]P(x\ \textgreater \ a)=1-P(x\ \textless \ a)=1-P\left(z\ \textless \ \frac{a-\mu}{\frac{\sigma}{\sqrt{n}}}\right)[/tex]

Given that the average precipitation in Toledo, Ohio for the past 7 months is 19.32 inches with a standard deviation of 2.44 inches, the probability that 5 randomly selected years will have precipitation greater than 18 inches for the first 7 months is given by:

[tex]P(x\ \textgreater \ 18)=1-P(x\ \textless \ 18) \\ \\ =1-P\left(z\ \textless \ \frac{18-19.32}{\frac{2.44}{\sqrt{5}}}\right) \\ \\ =1-P(z\ \textless \ -1.210) \\ \\ =1-0.1132=\bold{0.8868}[/tex]

Using the normal distribution and the central limit theorem, it is found that there is a:

a) 0.7054 = 70.54% probability that a randomly selected year will have precipitation greater than 18 inches for the first 7 months.b) 0.8869 = 88.69% probability that five randomly selected years will have an average precipitation greater than 18 inches for the first 7 months.

Normal Probability Distribution

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

It measures how many standard deviations the measure is from the mean.  After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

In this problem:

The mean is of 19.32 inches, hence [tex]\mu = 19.32[/tex].The standard deviation is of 2.44 inches, hence [tex]\sigma = 2.44[/tex].

Item a:

The probability that a randomly selected year will have precipitation greater than 18 inches for the first 7 months is 1 subtracted by the p-value of Z when X = 18, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{18 - 19.32}{2.44}[/tex]

[tex]Z = -0.54[/tex]

[tex]Z = -0.54[/tex] has a p-value of 0.2946.

1 - 0.2946 = 0.7054.

0.7054 = 70.54% probability that a randomly selected year will have precipitation greater than 18 inches for the first 7 months.

Item b:

Now, we want the probability that five randomly selected years will have an average precipitation greater than 18 inches for the first 7 months, hence:

[tex]n = 5, s = \frac{2.44}{\sqrt{5}}[/tex]

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{18 - 19.32}{\frac{2.44}{\sqrt{5}}}[/tex]

[tex]Z = -1.21[/tex]

[tex]Z = -1.21[/tex] has a p-value of 0.1131.

1 - 0.1131 = 0.8869.

0.8869 = 88.69% probability that five randomly selected years will have an average precipitation greater than 18 inches for the first 7 months.

Simplify an expression

Answers

Answer:

[tex]\frac{20+2k}{3k+12}[/tex]

Step-by-step explanation:

Since there is no equals sign here, we are not solving this.  The only way to simplify is to get a common denominator and write the expression as a single expression.  We can begin by noting that the second term has a k in the numerator and in the denominator, and those cancel each other out.  That is the first simplification we can perform.  That leaves us with:

[tex]\frac{4}{k+4}+\frac{2}{3}[/tex]

In the first term, the denominator is k + 4, in the second term it is just 3.  Therefore, the common denominator is 3(k+4).  We are missing the 3 in the denominator of the first term, so we will multiply in 3/3 by that term.  We are missing a (k + 4) in the second term, so we will multiply in (k + 4)/(k + 4) by that term:

[tex](\frac{3}{3})(\frac{4}{k+4})+(\frac{k+4}{k+4})(\frac{2}{3})[/tex]

Multiplying fractions requires that I multiply straight across the top and straight across the bottom.  That gives me:

[tex]\frac{12}{3k+12}+\frac{2k+8}{3k+12}[/tex]

Now that the denominators are the same, I can put everything on top of that single denominator:

[tex]\frac{12+2k+8}{3k+12}[/tex]

Th final simplification requires that I combine like terms:

[tex]\frac{20+2k}{3k+12}[/tex]
