Answer:

e. 0.0704

Step-by-step explanation:

We solve this problem building the Venn's diagram of these probabilities.

I am going to say that:

A is the probability that a student plays baseball.

B is the probability that a student plays soccer.

We have that:

$A = a + (A \cap B)$

In which a is the probability that a student plays baseball but not soccer and $A \cap B$ is the probability that a student plays both of these sports.

By the same logic, we have that:

$B = b + (A \cap B)$

18% of all students at West Colon High School play baseball and 32% play soccer.

This means that $A = 0.18, B = 0.32$

The probability that a student plays baseball given that the student plays soccer is 22%.

This means that

$\frac{A \cap B}{B} = 0.22$

Calculate the probability that a student plays both baseball and soccer.

This is $A \cap B$

$\frac{A \cap B}{B} = 0.22$

$\frac{A \cap B}{0.32} = 0.22$

$A \cap B = 0.32*0.22 = 0.0704$

So the correct answer is:

e. 0.0704

Answer:

Step-by-step explanation:

There is no answer choices so I can't really select an answer so I just provided my own. If you do provide the answer choices and my answer is wrong tell me and I will gladly change it. Anyways my explanation is since there are 7 days in a week and she collected 7 leaves for a week you would find this answer out by multiplying 7 by 7. 7x7=49

If y=2cos(x/2) then d^2y/dx^2 =

Sladkaya [172]

We first need dy/dx.

dy/dx = -2sin(x/2)(1/2)

dy/dx = -sin(x/2)

We now find d^2y/dx^2.

d^2y/dx^2 = -cos(x/2)(1/2)

d^2y/dx^2 = -(1/2)cos(x/2)

Multiply or divide change your answer to a mixed frqction in lowest terms if necessary.

Alinara [238K]

24 divided by 8 equals 3
12 divided by 3 is 4
3 times 7 is 21
2 times 6 is 12
5 times 6 is 35
16 divided 4 is 4
