first you need to find the least common denominator which in this case it is 40. since 5 and 8 both go into 40.


5/8 = 25/40

3/5 = 24/40

25/40 - 24/40 =1/40

does this make sense to you?

In a city, 60% of the residents live in houses and 40% of the residents live in apartments.Of the people who live in houses, 20%
DIA [1.3K]

Answer:

0.75 or 75%

Step-by-step explanation:

The probability that a resident lives in a house and owns their own business is:

P(H\cap B)=0.6*0.2\\P(H\cap B)=0.12

The probability that a resident lives in an apartment and owns their own business is:

P(A\cap B)=0.4*0.1\\P(A\cap B)=0.04

Therefore, the probability that a person lives in a house, given that they own their own business is:

P(H|B) = \frac{P(H\cap B)}{P(H\cap B)+P(A\cap B)}\\P(H|B) = \frac{0.12}{0.12+0.04} \\P(H|B) = 0.75

The probability is 0.75 or 75%.

What is the measure of the exterior angle
Nataliya [291]

Answer:

That exterior angle is equal to 87 degrees.

Step-by-step explanation:

In order to find the measure of the exterior angle, we start by trying to find x. We can do this by adding up the 3 interior angles and setting them equal to 180. The first angle is equal to 43. The second angle is equal to x + 15. The third angle is equal to 180 - 3x (which we know because the angle and 3x is equal to 180). So we set equal to 180.

43 + (x + 15) + (180 - 3x) = 180 ----> Combine like terms.

238 - 2x = 180 -----> Subtract 238

-2x = -58 ----> Divide by -2

x = 29

Now that we have the x value, we can plug into the exterior angle measure to get the value.

3x = 3(29) = 87 degrees
