Answer: The required probability is 0.008.

Step-by-step explanation:

Since we have given that

Probability of bachelor's degree = 0.45

Probability of working in nursing = 0.85

Probability of both = 0.4

So, Probability of getting a graduate is currently working in nursing, given that they earned a bachelor's degree would be :

P(N|B)=\dfrac{P(N\cap B)}{P(B)}\\\\P(N|B)=\dfrac{0.4}{0.45}\\\\P(N|B)=0.008

Hence, the required probability is 0.008.

erastova [34]
To answer, we let x be the total number of lions in the zoo. Since, we are given that 2/6 of these lions are not well, this means that 4/6 of them are well. The given 10 is the number of lions that are well. 
                                (4/6)(x) = 10
The value of x is 15. Therefore, 5 of the lions are ill.

The equations below represent the numbers y of tickets sold after x weeks for two different local music festivals.
kiruha [24]

Answer:

Part a) 3.5 weeks

Part b) 185 tickets

Step-by-step explanation:

Part a) After how much time have the same number of tickets been sold for both festivals?

Let

x -----> the number of weeks

y ----> the number of tickets sold

we have

<em>Country Music Festival</em>

y=10x+150 ----> equation A

<em>Pop Music Festival</em>

y=20x+115 ----> equation B

Equate equation A and equation B

20x+115=10x+150

solve for x

20x-10x=150-115

10x=35

x=3.5\ weeks

Part b) What is the number of tickets sold at that time?

substitute the value of x=3.5 weeks  in the linear equation A or linear equation B

y=10(3.5)+150

y=35+150

y=185\ tickets
