5 0

Answer:

They are equal

Both answer is 65

Step-by-step explanation:

5x -30 = 2x +27

5x -2x = 27 +30

3x = 57

x = 57/3 = 19

5x -30 = 5(19) -30 = 65

2x +27 = 2(19) +27 = 65

Bad gums may mean a bad heart. Researchers discovered that 82% of people who have suffered a heart attack had periodontal diseas
saveliy_v [14]

Answer:

37.27% probability that he or she will have a heart attack.

Step-by-step explanation:

Bayes Theorem:

Two events, A and B.

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

In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.

In this question:

Event A: Periodontal disease

Event B: Heart attack

Researchers discovered that 82% of people who have suffered a heart attack had periodontal disease, an inflammation of the gums.

This means that P(A|B) = 0.82

Only 33% of healthy people have this disease.

This means that P(A) = 0.33

Suppose that in a certain community heart attacks are quite rare, occurring with only 15% probability.

This means that P(B) = 0.15

If someone has periodontal disease, what is the probability that he or she will have a heart attack

P(B|A) = \frac{0.15*0.82}{0.33} = 0.3727

37.27% probability that he or she will have a heart attack.

If the person borrowed $3000 for 3 years at a rate of 2%, how much interest will they owe for the loan
krek1111 [17]

In this case were going to solve the question using "simple interst", so since were looking for the interest it will be I= PxRxT (I stands for "interest", P stands for "principal", R stands for "rate" and T stands for "time")

so P is $3000

R is 2%

and T is 3 years

so we'll have to turn our rate into a decimal which is 2% = .02

now to start the problem:

I= (3000)(.02)(3)       (means 3000 x .02 x 3)

I= $180  is your answer
