In Statsville, MA, 76% of households own cars, 12% own motorcycles, and 8% of households own both. What is the probability that
olasank [31]

Answer:

The answer is 0.105

Step-by-step explanation:

Let cars =C and motorcycles=M.

now, P(C)=76 percent =0.76

P(M)=12 percent=0.12

P(C∩M)=8 percent =0.08

Then, the probability that a person owns a motorcycle, given they own a car, is a conditional probability given by the definition

P(M/C)=\frac{P(M∩C}{P(C)}=\frac{0.08}{0.76}=0.105

Therefore, the answer is 0.105

I believe it is well understood.

What is the solution set for - 4x + 10 = 5x + 55?
Lina20 [59]

Answer:

x=−5

Step-by-step explanation:

Step 1: Subtract 5x from both sides.

−4x+10−5x=5x+55−5x

−9x+10=55

Step 2: Subtract 10 from both sides.

−9x+10−10=55−10

−9x=45

Step 3: Divide both sides by -9.

−9x

−9

=

45

−9

x=−5

Answer:

x=−5
