Find the mean of the data in the bar chart below.

Answers

Answer 1

Answer:

9/2≈4.5

Step-by-step explanation:

mean is 4, 5,6,3

Find the mean of the list:

(4, 5, 6, 3)

The mean of a list of numbers is given by:

(sum of elements)/(number of elements)

(sum of elements) = 4 + 5 + 6 + 3:

(4 + 5 + 6 + 3)/(number of elements)

Counting, we see that the list has 4 elements:

(4 + 5 + 6 + 3)/4

4 + 5 + 6 + 3 = 18:

18/4

18/4 = 9/2:

Answer: 9/2≈4.5

Answer 2

4.5, you just have to find the average

14. It is 116.80

because the formula is π x r² so 6.1² x 3.14= 116.8394

15. It is 50.20

because the formula is r²*3.14 and the radius if half of the diameter and the diameter is 8 and half of it would be 4 and 4²=16 so 16*3.14= 50.24

Which quadrilateral can be classified as a trapezoid?

Answers

Answer:

a trapezoid is a shape with only two sides that are parallel. so the right answer is the light green shape with only two sides having arrows, the top and bottom. i hope that helps, have an amazing day! (:

Step-by-step explanation:

These two parts are equal in length. The attributes indicate that a rhombus can also be classified as a parallelogram and all parallelograms are also classified as a trapezoid. Since opposite side are parallel, we can classify the rectangle as a parallelogram and a trapezoid.

HELP! 6th-grade math PLEASE HELP!

Answers

first, find the area of prism ll by multiplying 5/2, 9/4, and 2

this will result in 45/4, or 11.25

now, you have to figure out how many small cubes will fit inside prism ll

we know that the side lengths of the small cubes are 1/4, and since cubes have equal side lengths, you can multiply 1/4, 1/4, and 1/4 to find the area

this will result in 1/64

divide the area of prism ll, 11.25, by the area of the small cubes, 1/64, to get 720

then, do the same thing for prism l

multiply 7/4, 3/2, and 5/4 to get 105/32

divide this by the previous 1/64 to get 210

lastly, to determine how many more small cubes can fit into prism ll, subtract 210 from 720

720-210=510

final answer: 510 cubes

Stephanie is helping her band collect money to fund a field trip.
The band decided to sell boxes of chocolate bars. Each bar sells
for $1.50 and each box contains 20 bars. Below is a partial table
of monies collected for different numbers of boxes sold.
Boxes Sold (b) Money Collected (m)
1 $30
2 $60
3 $90
4 $120
5 $150
6 $180
7 $210
8 $240

1.) Complete the table above for all values of m.

2.) Which is the independent variable?

3.) Which is the dependent variable?

4.) Write an equation for the amount of money, m, that will be
collected if b boxes of chocolate bars are sold.

5.) Graph the equation using the ordered pairs from the table
above.
(Don’t forget to label your axes and increments!)

6.) How much money will be collected if 100 boxes of chocolate
bars are sold?

7.) The band collected $1530 from chocolate bar sales. How
many boxes did they sell?

Answers

Answer:

O P=20($1.50)

They will make $3,000 if they sell 100 boxes of chocolates

Step-by-step explanation:

It is multiplication because it is $1.50 per each chocolate bar, and since there is 20 per box, we need to find the profit for the entire box

using that info, we find that each box of chocolates is 30 dollars

multiplied by 100 boxes is $3000.

Can anyone solve this?

Answers

Answer:

324 inches squared

Step-by-step explanation:

The question is most likely asking for the surface area of the rectangular prism.

The Formula for this is:

2(wl+hl+hw)

h = 6in

w = 5in

l = 12in

Plug in the varibles:

2( 5*12 + 6*12 + 6*5)

Simplify:

2( 60 + 72 + 30) =

2(162) =

324

So the answer is 324 inches squared!

Hope this helps! :)

Answer:

The surface area of the rectangular prism is: 324

The volume of the rectangular prism is: 360

Step-by-step explanation:

Surface area is calculated with the formula:

2(wl + hl + hw)

w*l = 6*12 = 72

h*l = 5*12 = 60

h*w = 5*6 = 30

Now add up 72, 60, and 30.

72+60+30 = 162.

This leaves us with the equation:

2(162)

So, we multiply 2 and 162 to get the surface area.

2*162 = 324.

For the volume, we multiply the length, width, and height altogther.

l*w*h

So, we plug in the values, and multiply:

12*6*5 = 360

The volume is 360 in^3
