What is the area of a circle with radius 7.5
Answer: Last option

Step-by-step explanation:
the probability of a jaywalker being hit is
.
So the probability of a jaywalker not being hit is:


As in this experiment the probability of each trial is independent then, the probability that it is not a jaywalker will not be hit if it makes a round trip is:


If this experiment is repeated for 30 days then the probability that it is not a jaywalker will not be hit if it makes a round trip is:

Answer:
<h2>cos(∠B) = CB/AB = ED/AD</h2>
Step-by-step explanation:

Use the Midpoint Theorem to solve for x.
The theorem states that the line between the midpoints of a triangle is half the length of the side it's opposite to.
Line BF is opposite to Line CE. Line CE has a length of 88. Therefore, we can set up the following equation:


Divide both sides by 2 to get x by itself:

The value of x is
22.
Answer:
314ft²
Step-by-step explanation:
A = πr²
A= π10²
A=100π
A=100*3.14
A=314
Hope this helps :)
