Please help me 20 points
otez555 [7]

Add up the number of students within the random sample data:
32+26+28+22 = 108

We can then use proportional fractions / cross-multiply to answer the question.

In a sample size of 108 students, 32 of them preferred Movie A.
There are 900 students in total.

\frac{32}{108} =\frac{x}{900}

32*900 = 28800

108*x = 108x

108x = 28800

x = 266\frac{2}{3} or \frac{800}{3}

In decimal form that is approximately 266.667 and round that to the nearest whole number, you get 267 students who would prefer Movie A.

Pyramid A is a square pyramid with a base side length of 12 inches and a height of 8 inches. Pyramid B has a volume of 3,456 cub
anastassius [24]

Step-by-step explanation:

We know that

Volume of square pyramid = a² × h/3

=> (12)² × 8/3

=> 144 × 8/3

=> 48 × 8

=> 384 in³

Now,

We need to find ratio for finding the times of the volume

=> 3456/384

=> 9

Hence,

Volume of pyramid B is 9 times greater than the volume of pyramid A

What is the area of this shape? I got 1800 square foot. PLEASE HELP!!!!! How did you get the answer also?
Delvig [45]
For this question first you should find the area of the triangle so you should say:
3*6/2 = 18/2 = 9 ft
now you should find the area of the rectangular so you should say:
16*8 = 128 ft 
now you should add them together so you will have:
128 + 9 = 137 square foot :)))
i hope this is helpful
have a nice day
