The sample is his friends. They might be the same group of interests. The sample needs to be random. Even if he went around and grabbed random people he may not have known at his school, it still wouldn't be random bc they could all be bias towards a local sports team or have different interests than someone from somewhere else
A. 9
B. 24
C. 6
D. 16
Step-by-step explanation:
Given ratios are;
A. 2 : 3 = 6 : x
Product of mean = Product of extreme

Dividing both sides by 2

B. 4 : 7 = x : 42
Product of mean = Product of extreme

Dividing both sides by 7

C. 2x : 48 = 3 : 12
Product of extreme = Product of mean

Dividing both sides by 24

D. 12 : 15 = x : 20
Product of mean = Product of extreme

Dividing both sides by 15

it would be 20% if 0.2 omg
Answer:
(x-8)^2+(y-16)^2 = 4
Step-by-step explanation:
The equation of a circle is given by
(x-h)^2+(y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x-8)^2+(y-16)^2 = 2^2
(x-8)^2+(y-16)^2 = 4
