Bradley wanted a blue gumball and a green gumball from a vending machine. There were 15 blue gumballs, 12 yellow gumballs, 2 green gumballs, and 16 purple gumballs. How many times would you expect to get a blue gumball or green gumball if a gumball was taken out 250 times?

Answers

Answer 1

Answer: Bradley would expect 94 times to get a blue or green gumball.

Step-by-step explanation:

Since we have given that

Number of blue gumballs = 15

Number of yellow gumballs = 12

Number of green gumballs = 2

Number of purple gumballs = 16

Total number of all gumballs = 45

Probability of getting either a blue gumball or green gumball be

[tex]\frac{15}{45}+\frac{2}{45}=\frac{17}{45}[/tex]

So, Expectation of getting a blue gumball or green gumball if a gumball was taken out 250 times :

[tex]\frac{17}{45}\times 250=94.4[/tex]

Since we know that it must be less than 94.4.

So, the nearest smallest integer will be 94 times .

Hence, Bradley would expect 94 times to get a blue or green gumball.

Step-by-step explanation:

Divide the distance D over the time T. If you travel D = 325 miles for T = 5 hours, then your speed or rate R is

R = D/T = 325/5 = 65

So you're traveling at 65 miles an hour if you travel 325 miles in 5 hours, which is what the upper left corner diagram is showing.

4/7 times a number minus 8.5 is no more than 11.5

Answers

good luck finding this answer 211

Hi there! :)

Answer:

4/7 times 35, minus 8.5 is no more than 11.5

The number is : 35


Step-by-step explanation:

Let's replace "a number" by the letter "x" because that's what we are looking for.

4/7 × x = 4/7x

4/7x MINUS 8.5 = 4/7x - 8.5

The expression "no more than" is represented by this sign: ≤

"No more than" can also be "less than or equal to".


The final inequality should look like this:

4/7x - 8.5 ≤ 11.5


Now all you need to do is solve the inequality by isolating "x":

4/7x - 8.5 ≤ 11.5

Add 8.5 to each side of the inequality → 11.5 + 8.5 = 20

4/7x ≤ 20

Divide each side of the inequality by "4/7" → 20 ÷ 4/7 = 35

x ≤ 35


There you go! I really hope this helped if there's anything just let me know! :)

Problem 7 is choice B, which is the entire number line shaded in but the value -4 has a hole at this location to mean "exclude this point from the solution set". So basically x can be any number but -4.

Problem 8 is choice C. You have a closed circle (or filled in hole) at -1.5 on the number line. Then you shade to the left of the closed circle to indicate the set of values that are smaller than this endpoint. So n can be -1.5 or it can be smaller than -1.5 (something like -2 or -3, etc).

A square is inscribed in a right triangle so that they have a common right angle. The legs of the triangle are 6 in and 8 in long.Find the length of the side of the square.

Answers

Answer: Approximately 3.42857142857142 inches

Round this value however you need to. For instance, if you need to round to 2 decimal places, then the answer would be 3.43 inches.

====================================================

How I got this answer:

A square has side lengths that are the same value and it has four right angles. For example, a square could have all four sides equal to 7 inches. We want this square to fit snugly inside a right triangle. Put another way, we want this square as big as possible without it overflowing outside the triangle.

If one vertex of the square is at (0,0) then the opposite vertex will be on the line y = x meaning this opposite vertex's location is (x,x). The x refers to the side length of the square. Replace x with any number. Going back to the previous example, if x = 7 then the square has two opposite vertices at (0,0) and (x,x) = (7,7), so this square has side length of 7. We will use the equation y = x later on (see figure 2 in the attached images below). I marked (0,0) as point A and (x,x) as point D in figure 3.

We will also use the equation of the line that goes through the two points B(0,6) and C(8,0) as shown in figure 3. The line that goes through points B and C is the line that forms the hypotenuse of the right triangle. If we can find the equation of this line, then we can use algebra to find the intersection point D (see figure 3)

It turns out that the equation of the line through B and C is y = (-3/4)x + 6. Check out figure 1 in the attached images below to see how I got that.

Then head over to figure 2 to see how I'm using the two equations to solve for x. The exact solution is the fraction x = 24/7 which approximates to x = 3.42857142857142 and you can round this however you want for the final answer.


The side length of the square inscribed in the right triangle with legs 6 inches and 8 inches is  [tex]\(\frac{24}{7}\)[/tex] inches.

Let's denote the side length of the square as ( s ). Since the square is inscribed in the right triangle with a common right angle, the triangle can be split into two smaller right triangles and a rectangle.

Consider the right triangle with legs of lengths 6 inches and 8 inches. When a square is inscribed in such a triangle, the side of the square, ( s ), will align with one leg and the other leg, forming two smaller right triangles and a rectangle.

We can solve this problem by using the properties of similar triangles. Let’s break down the larger right triangle into the smaller components formed when the square is inscribed.

Step-by-Step Solution:

1. Draw the square inscribed in the right triangle. Denote the point where the side ( s ) of the square touches the leg of length 6 inches as point ( A ), and the point where it touches the leg of length 8 inches as point ( B).

2. Let the triangle's right angle be at point ( C ). Place the square such that one vertex coincides with point ( C). Let the opposite vertex of the square that lies on the hypotenuse be point ( D).

3. The length of the segment along the 6-inch leg outside the square is ( 6 - s ). Similarly, the length of the segment along the 8-inch leg outside the square is ( 8 - s ).

Using Similar Triangles:

The smaller triangles formed by the inscribed square and the segments  [tex]\( 6 - s \) and \( 8 - s \)[/tex] are similar to the original right triangle (by AA similarity).

The ratio of the sides of these similar triangles remains the same:

[tex]\[\frac{s}{6 - s} = \frac{8}{6}\][/tex]

Now solve for  [tex]\( s \):[/tex]

[tex]\[\frac{s}{6 - s} = \frac{4}{3}\][/tex]

Cross-multiplying gives:

[tex]\[3s = 4(6 - s)\]\[3s = 24 - 4s\]\[3s + 4s = 24\]\[7s = 24\]\[s = \frac{24}{7}\][/tex]

So, the side length of the square is:

[tex]\[s = \frac{24}{7} \approx 3.43 \text{ inches}\][/tex]

Thus, the length of the side of the square inscribed in the right triangle with legs 6 inches and 8 inches is  [tex]\( \boxed{\frac{24}{7}} \)[/tex]  or approximately 3.43 inches.

7 is factor of 21 so 7 is also factor of 79275.


21 is a factor of 79275 then 7 is also a factor of number  79275

What is Number system?

A number system is defined as a system of writing to express numbers.

To determine if a number is a factor of 79275, we need to check if it divides evenly into 79275 without leaving a remainder.

Since 21 is a factor of 79275

we can write 79275 as 21 multiplied by some other number

79275 = 21 × (some number).

If a number is a factor of both 21 and (some number), it will also be a factor of their product, which is 79275.

The only number that is a factor of 21 is 7.

Therefore, 21 is a factor of 79275 then 7 is also a factor 79275

Answers

Answer:

y+3 = 4(x+1)

Step-by-step explanation:

Point slope form of a line is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point

y--3 = 4 (x--1)

y+3 = 4(x+1)

Answer:  plot slope form is y+3= 4(x+1)

                                    or

                     y = 4x+1

Step-by-step explanation:

Slope point form of equation is given by

    y-y1 = m (x-x1)

           where m is slope and (x1,y1)  is the point

here (point) is (-1,-3)  and slope = 4

so equation is

(y - (-3) )= 4 ( x -(-1))

y+3 = 4(x+1)

y+3 = 4x+4

y = 4x +1

Step-by-step explanation:


Answer:

[tex]y=cos(x+\pi )[/tex]

Step-by-step explanation:

We are a given a graph from which we can clearly see that y = -1 when x  = 0.

Next, to find out which of the options is the equation of the given graph, we need to set our calculator to the radian mode and then we will put the value of x to be 0.

1. y = cos(x + pi/2) = cos(0 + pi/2) = 0

2. y = cos(x+2pi) = cos(0+2pi) = 1

3. y = cos(x+pi/3) = cos(0+pi/3) = 1/2 = 0.5

4. y = cos(x+pi) = cos(0+pi) = -1

We get y = -1 when x = 0 in equation number 4, y = cos(x+pi) = cos(0+pi) = -1. so that is the equation of the given graph.

Please help answer these questions. My teacher said they were really easy but I just don't understand. Will mark brainliest !!!

Answers

Answer:

1.  A = 59

2.  A = 43

Step-by-step explanation:

If we have a right triangle  we can use sin, cos and tan.

sin = opp/ hypotenuse

cos= adjacent/ hypotenuse

tan = opposite/ adjacent


For the first problem, we know the opposite and adjacent sides to angle A

tan A = opposite/ adjacent

tan A = 8.8 / 5.2

Take the inverse of each side

tan ^-1 tan A = tan ^-1 (8.8/5.2)

A = 59.42077313

To the nearest degree

A = 59 degrees


For the second problem, we know the  adjacent side and the hypotenuse to angle A

cos A = adjacent/hypotenuse

cos A = 15.3/21

Take the inverse of each side

cos ^-1 cos A = cos ^-1 (15.3/21)

A = 43.23323481

To the nearest degree

A = 43 degrees


Question: Find the ratio of the width to the length of the rectangular swimming pool sketched below. Width=5.5 yards | Length=7.5 yards | Answers are: A) 11/24 yards B) 2.75/15 yards C) 15/11 yards D) 11/15 yards. Which one is it?

Answers

Answer:

D) 11/15

Step-by-step explanation:

11/15 is the doble amount of 5.5/7.5, but is the same number if you divide it.

The ratio of the width to the length of the swimming pool with a width of 5.5 yards and a length of 7.5 yards is 11/15 yards, which corresponds to answer D) 11/15 yards.

The student has asked to find the ratio of the width to the length of a rectangular swimming pool where the width is 5.5 yards and the length is 7.5 yards. To find this ratio, we divide the width by the length:

Ratio = Width / Length = 5.5 yards / 7.5 yards. Simplifying this we get:

Ratio = 11/15 yards.

Therefore, the correct answer is D) 11/15 yards.

Samuel compared the monthly rental rates of two-bedroom apartments in Beverly and Lowell over the years. The results are shown in the table below. Time (years) Beverly Rent ($) Lowell Rent ($) 0 1,870 1,600 1 1,890 1,680 2 1,950 1,764 3 2,055.50 1,852.20 4 2,175.75 1,944.81 Which statement best describes this situation? A. Only the monthly rental cost of apartments in Beverly is changing exponentially. B. Only the monthly rental cost of apartments in Lowell is changing exponentially. C. The monthly rental cost of apartments in neither town is changing exponentially. D. The monthly rental cost of apartments in both the towns is changing exponentially.

Answers

Answer:

B. Only the monthly rental cost of apartments in Lowell is changing exponentially.

Step-by-step explanation:

To identify how the values ​​of the monthly costs of the departments are changing, we must do a test.

The test consists of taking an element [tex]n_{-1}[/tex] and the element n of the series, and dividing [tex]\frac{n}{n_{-1}} = a[/tex]

Then take the element [tex]n_{+1}[/tex] and the element n and divide [tex]\frac{n_{+1}}{n} = b[/tex]

If b = a, then the exponential function of base "b"

But if b> a, then the rate of change of the function is not exponential

For example. For the cost of apartments in Beverly

[tex]n_{-1} = 1870\\n = 1890\\n_{+1} = 1950\\\\\frac{n}{n_{-1}} = \frac{1890}{1870} = 1.011\\\\\frac{n_{+1}}{n} = \frac{1950}{1890} = 1.032\\\\1,032> 1,011[/tex]

So, the cost of apartments in Beverly does not increase at an exponential rate.

We do the same for the cost of the apartments in Lowell.

[tex]n_{-1} = 1600\\n = 1680\\n_{+1} = 1764\\\\\frac{n}{n_{-1}} = \frac{1680}{1600} = 1.05\\\\\frac{n_{+1}}{n} = \frac{1764}{1680} = 1.05\\\\1.05 = 1.05[/tex]

The rate is the same, so the prices increase exponentially.

Finally, the correct answer is option B: B. Only the monthly rental cost of apartments in Lowell is changing exponentially.

Answer:

B. Only the monthly rental cost of apartments in Lowell is changing exponentially.

The correct answer is option (b).20% is equivalent to the fraction [tex]$\frac{8}{40}$[/tex]

To find the percent equivalent to the fraction [tex]$\frac{8}{40}$[/tex], we first simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 4 in this case.

[tex]$$\frac{8}{40} = \frac{8 \div 4}{40 \div 4} = \frac{2}{10}$$[/tex]

Now, we convert the simplified fraction to a percentage by multiplying it by 100.

[tex]$$\frac{2}{10} \times 100 = 20\%$$[/tex]

Therefore, 20% is equivalent to the fraction [tex]$\frac{8}{40}$[/tex].
