Answer:

13 cm

Step-by-step explanation:

The diagonal of a rectangle forms a right triangle; where the diagonal is a hypotenuse, and two sides of the rectangle are legs.

Using pythagorean's theorem ( $a^2 + b^2 = c^2$ ), we can say:

$5^2 + 12^2 = c^2\\25 + 144 = c^2\\169 = c^2\\13 = c$

The hypotenuse is equal to 13cm.

A linear function has a slope of 4 and a y-intercept of (0,-8). What is the x-intercept of the line?

miss Akunina [59]

Answer:

The answer to your question is 2 or (2, 0)

Step-by-step explanation:

Data

slope = m = 4

y-intercept = -8

Process

1.- Write the equation of the line in the slope y-intercept

y = mx + b

In this equation:

m = slope

b = y-intercept

-Substitution

y = 4x - 8

2.- To find the x-intercept, consider that y = 0 and solve for x.

0 = 4x - 8

4x = 8

x = 8/4

x = 2 or (2, 0)

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.
