Answer:

There is a 2.17% probability that a randomly selected person aged 40 years or older is male and jogs.

It would be unusual to randomly select a person aged 40 years or older who is male and jogs.

Step-by-step explanation:

We have these following probabilities.

A 13.9% probability that a randomly selected person aged 40 years or older is a jogger, so P(A) = 0.13.

In​ addition, there is a 15.6% probability that a randomly selected person aged 40 years or older is male comma given that he or she jogs. I am going to say that P(B) is the probability that is a male. P(B/A) is the probability that the person is a male, given that he/she jogs. So P(B/A) = 0.156

The Bayes theorem states that:

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

In which P(A \cap B) is the probability that the person does both thigs, so, in this problem, the probability that a randomly selected person aged 40 years or older is male and jogs.

So

P(A \cap B) = P(A).P(B/A) = 0.156*0.139 = 0.217

There is a 2.17% probability that a randomly selected person aged 40 years or older is male and jogs.

A probability is unusual when it is smaller than 5%.

So it would be unusual to randomly select a person aged 40 years or older who is male and jogs.

to graph
start at center and go 5 up, that is y intercept
go 1 right and 2 up, that is another point

y=2(2)+5
y=4+5

Grade 9 math plzz helpp a or b or c or d
hram777 [196]

Answer:

g(x) = 3^{x -4}

Step-by-step explanation:

Given

f(x) = 3^x

g(x) = f(x) 4 units left

Required

Find g(x)

When a point is translated 4 units left, the rule is:

x \to x - 4

So, we have:

g(x) = f(x-4)

f(x-4) is calculated as:

f(x-4) = 3^{x -4}

Hence:

g(x) = 3^{x -4}
