Kobotan [32]

Answer:

Step-by-step explanation:

The answer for this is

See the red line in the graph which says f(X)

See the blue line in the graph which says g(X)

So these are the variables which come under the example of exponential functions

And the answer is option B. Both graphs are exponential functions.

Answer please GIVING BRAINLIEST

Kaylis [27]

Answer:

see below

Step-by-step explanation:

defining variables:

since you are trying to find t shirt cost and jeans cost, your variables would be

the cost of the t shirt and the cost of jeans, denoted by any variable you want.

I'll use x and y since they are the most common variables (x = shirt y = jeans)

Equation

4 shirts + 5 jeans = 160 dollars

4x + 5y = 160 (the cost of 4 shirts + the cost of 5 jeans is $160)

the cost of 2 shirts + 6 jeans = $150

2x + 6y = 150

Bad gums may mean a bad heart. Researchers discovered that 80% of people who have su ered a heart attack had periodontal disease

saul85 [17]

Answer:

0.069 = 6.9% probability that he or she will have a heart attack

Step-by-step explanation:

Conditional Probability

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: Does not have periodontal disease

Event B: Has a heart attack.

Probability of not having a periodontal disease:

100 - 80 = 20% of 10%(had a heart attack).

30% of 100-10 = 90%(did not have a heart attack). So

$P(A) = 0.2*0.1 + 0.3*0.9 = 0.29$

Intersection of A and B:

Not having the disease, suffering a heart attack, so 20% of 10%.

$P(A cap B) = 0.2*0.1 = 0.02$

What is the probability that he or she will have a heart attack?

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.02}{0.29} = 0.069$

0.069 = 6.9% probability that he or she will have a heart attack
