The value of a dirt bike decreases by 25% each year. If you purchased this dirt bike today for $500, to the nearest dollar how m

Harman [31]

First. Find out what 25% of 500 is,then minus that from 500 five times.

It wont be worth anything because it will be $-125 in 5 years.

500-125-125-125-125-125= -125

In January, a dealership sold 164 vehicles. In February, the same dealership sold 23.8% fewer vehicles than they sold in January

sattari [20]

23.8% of 164 is 39.032 so minus that off of 164 and you would've sold 124.968 cars and im guessing you should round so the dealership would've sold 125 cars.

If P(A)=0.4, P(A and B)=0.2,and P(A or B)=0.5, What is P(B)

Vladimir [108]

Answer:

$\boxed{\ P(B)=0.3 \ }$

Step-by-step explanation:

Hi,

We know that

P(A or B)=P(A)+P(B)-P(A and B)

so P(B)= P(A or B) - P(A) + P(A and B)

P(B) = 0.5 - 0.4 + 0.2 = 0.3

thanks

Suppose you flip 3 quarters, one at a time. What is the probability that you will

Semenov [28]

Answer:

The probability of the combination {H, T and H} is 0.125.

Step-by-step explanation:

The sample space of flipping a quarter is:

S = {H and T}

The probability of both outcomes is same, i.e. P (H) = P (T) = 0.50.

It is provided that three quarters are flipped one at a time.

The outcomes of all the three quarters are independent of each other.

Compute the probability of the combination {H, T and H} as follows:

$P(\text{H},\text{T and H}) = P(\text{H})\times P(\text{T})\times P(\text{H})$

$=0.50\times 0.50\times 0.50\\=0.125$

Thus, the probability of the combination {H, T and H} is 0.125.
