Mrs. Baker conducted a survey in her classroom to determine what the students preferred to do during the summer break. Her survey revealed that 21 out of 30 students preferred to go swimming during the summer. If the school has a total of 1200 students, how many do you predict might enjoy swimming during the summer break?

Answer:

36.7

Step-by-step explanation:

32+16+54+60+26+32=220

220 divided by 6 is 36.6666666666

Answer:

37% ordered something else.

Step-by-step explanation:

First you add 28+35 and it will give you 63.

Then you will subtract 100 (the total percentage) by 63.

you will end up with 37.

add the percentage and it will be 37%.

Good Luck!! <3

Answer:

x = 15 degrees, one vertical angle is 165 degrees

Step-by-step explanation:

3x = x + 30

3x - x = 30

x(3-1) = 30

2x=30

x=15

All the angles need to add up to 360 degrees.

15 + 15 + 2y = 360

2y = 330

y=165

Answer:

The commute times are shorter and more predictable for City B.

Step-by-step explanation:

First, let's find the center of each set of data. We don't have to actually measure it, we can just approximate. For City A the center is around 30 minutes. For City B the center is around 15 or 20 minutes. We can clearly see that City B commute times are generally shorter than City A.

Next, let's find which city is more predictable. We can figure this out by looking at each city's range. City A has a range of 55. City B has a range of 35. Because City B has a smaller range, we can say that City B's commute times are more predictable.

Step-by-step explanation:

Answer:

Range = 7

Step-by-step explanation:

Range = Largest number - Smallest number (in the number set give)

Range =        97 - 90

Range =         7

Step-by-step explanation:

[tex] \twoheadrightarrow \: \: \sf{ {( - 4)}^{3} \cdot{( - 4)}^{7}}[/tex]

As we know that,

[tex] \odot \: \sf{ {a}^{n} \cdot{a}^{m} = {a}^{n + m} }[/tex]

So,

[tex] \twoheadrightarrow \: \: \sf{ {( - 4)}^{3 + 7} }[/tex]

[tex] \twoheadrightarrow \: \: \sf{ {( - 4)}^{10} }[/tex]

Answer:

= 4^12

16777216

= 16,777,216

Step-by-step explanation:

-4^5 *  -4^7

we add powers in all circumstances where both powers would naturally stay inside brackets = (4^5)x( 4^7) = 4^12

(-4 x-4 x-4 x-4 x -4 )  x  (-4x-4x-4x-4x-4x-4x-4)

= -1024 x -16384 = 16777216

because

1024 x 16384 = 16777216

if one was shown as (4^5)^7 then it would be a completely differnet question and then we would multiply the powers but symetrical multiplications like -4^5 x -4^7 we add them.

Answer:

220

Step-by-step explanation:

PEMDAS

Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

1. [81 - (4 x 6)], do the parentheses inside the brackets

[81 - 24] = [57]

2. [tex]7^2=49[/tex], because it is an exponent

3. 49 + 3[57], do 3[57], because it is multiplication

49+171

A cylindrical swimming pool has a diameter of 16 feet and a height of 3 feet. How many gallons of water can the pool contain? Round your answer to the nearest whole number. (1 ft3 ≈ 7.5 gal)

Answer: 6029 gal

Answer:

a) Right, Has 1 Right Angle

b) Acute, All Angles Are Less Than 90

c) Obtuse, Has One Angle Larger Than 90

Step-by-step explanation:

Answer:

A. Increases by 3000%

B. Decreases by 3000%

Step-by-step explanation:

I’m not exactly sure, but yeah.

3000% = 30

So for A. Add 3000% or 30 to it to get 70

And the same for B. 70 - 3000% or 30 to get 40 again.

I hope this helps! Good luck :)

Answer: The mean is 5

Step-by-step explanation:

If you add all of the numbers and divide by how much numbers there are (8), then you get 5. Then the mean absolute deviation is the number away from the mean.

So I will put the mean absolute deviation in order of the numbers

4 (1 away from mean), 3 (2 away from the mean), 4( 1 away from the mean), 5 (same number as the mean), 6 (1 away from the mean), 6(1 away from mean), 8 (3 away from mean), and, finally another 4 (1 away)

Hope this helps :)

Answer:

1/1

Step-by-step explanation:

m=rise/run

Answer:

Your answer will be the third one.

Step-by-step explanation:

If you add up the numbers on top for the first, secnd, and fourth ones and divide that by the number ont he bottom, you will constantly get 6. However, for the third one, you'll get seven since 9+9 is 18 and 5+5 is 10. Add that up and you get 28, and divide that by 4 and you get 7, not 6. hope this helps!

Answer: (9+9+5+5)/4

Step-by-step explanation:

Because if you add all of the numbers on the numerator and divide by the denominator, all of them equal 6 except that one. So it doesn't belong

Answer:

112in²

Step-by-step explanation:

Formulas: V = [tex]\frac{lwh}{3}[/tex], V = lwh

Sub: v = [tex]\frac{4 x 4 x 6}{3}[/tex]

Solve: 32

Sub: v = 4 x 4 x 5

Solve: 80

V = 80 + 32

V = 112

The total volume of the figure is 112in²

Answer:

9 ft wide and 12 feet long

Step-by-step explanation:

Answer:

9 feet wide and 12 feet long

Step-by-step explanation:

On a calculator do 1.2 divided by 4. Then multiply what you get by 30. You will get 9. Then do 1.6 divided by 6. Multiply what you get by 45. You will get 12. It is important that you do not only find one and multiply it by both 30 and 45. You will get different things. Only use the difference with wide for wide and long for long.

Answer: Volume = 2613.81 units^3

Step-by-step explanation:

A cylinder is essentially a 3 dimensional circle. This means that we can find the volume by multiplying the area of the circle by the 3rd dimension, or the height.

This means the formula for the cylinder is (pi)(r^2)(h).

Now let's plugin the given variables.

(3.14)(8)(13).

(25.12)(13)

Volume = 2613.81 units^3
