of 360 consumers polled some purchase ice cream some purchase frozen yogurt and some purchase both if 260 people polled purchase
1 answer:
Answer: There are 350 consumers who purchase frozen yogurt.
Step-by-step explanation:
Since we have given that
Number of consumers polled =360
Number of consumers who purchased ice- cream = 260
Number of consumers who purchased both ice- cream and frozen yogurt = 250
We need to find the number of consumers who purchased frozen yogurt,
Let A denotes who purchased ice-cream
and B denotes who purchased frozen yogurt.
As we know the formula
Hence, there are 350 consumers who purchase frozen yogurt.

First let us find
Now let;s solve the second part
Circular pen means you are going to use Area = Pi(r^2).
So 78.5 = pi(r^2). Divide by pi on both sides to get r^2 = 78.5/pi. Take the square root of that to get r or radius = approximately 4.99. If you need an exact answer then use
for the next part because you are not done yet.
Plug whatever R you use into the circumference formula of Circumference = 2(pi)(r).
If you use 4.99, you do 2(pi)(4.99) which is approximately 31.35. If you use the exact answer, you do 2(pi)(
) which gives you approximately 31.41.
Either way you'll need about 31 meters of chicken wire but the 31.40796 or ~31.41 is closer to the exact answer.
