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.
32*900 = 28800
108*x = 108x
108x = 28800
x = or
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.

Answer:
The area is 7850 square inches
Step-by-step explanation:
Given the circumference, we want to calculate the area
mathematically, the circumference is;
C = 2 pi r
So r is C/2 pi
Area = pi * r^2
Substitute value for r from circumference;
Area = Pi * c^2/4pi^2
Area = C^2/4pi
Area = 314^2/4 * 3.14
Area = 7850 Inches square
Answer:
x=1
Step-by-step explanation:
2x-5<17
2x-5<17 Add 5 to both sides
+5 +5
2x<22 Divide by 2 to get x alone
/2 /2
x=11
