Ilia_Sergeevich [38]

Answer:

0.5934% probability that a baseball player will play at an NCAA college and will also go on to be drafted by the MLB

Step-by-step explanation:

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Playing at an NCAA college.

Event B: Being drafted by the MLB.

6.9% will play in an NCAA college

This means that P(A) = 0.069

8.6% of the college players will go on to be drafted by the MLB.

This means that P(B|A) = 0.086

What is the probability that a baseball player will play at an NCAA college and will also go on to be drafted by the MLB?

P(B|A) = \frac{P(A \cap B)}{P(A)}

P(A \cap B) = P(A) \times P(B|A)

P(A \cap B) = 0.069*0.086 = 0.005934

0.5934% probability that a baseball player will play at an NCAA college and will also go on to be drafted by the MLB

17. The length of a rectangle is 12 in, and the perimeter is 56 in. Find the width of the rectangle.
Ivahew [28]

Answer:

Step-by-step explanation:

P = 2(L + W)

P = 56

L = 12

now sub...we are looking for w

56 = 2(12 + W)

56 = 24 + 2W

56 - 24 = 2W

32 = 2W

32/2 = W

16 = W <==== the width is 16 inches

check...

P = 2(L + W)

56 = 2(12 + 16)

56 = 2(28)

56 = 56 (correct)
