y + 11 = -2x - 3

Subtract 11 from both sides;

y = -2x - 14

The manager of a gas station has observed that the times required by drivers to fill their car's tank and pay are quite variable

Nat2105 [25]

Answer:

The probability that a car driver can complete the transaction in less than 5 minutes is 0.4647.

Step-by-step explanation:

Let X = times required by drivers to fill their car's tank and pay.

The average time required by drivers is, β = 8 minutes.

The random variable X is Exponentially distributed with parameter, $\lambda=\frac{1}{\beta}=\frac{1}{8}=0.125$ .

The probability distribution function of exponential distribution is:

$f_{X}(x)=\lambda e^{-\lambda x};\ x>0$

Compute the probability that a car driver can complete the transaction in less than 5 minutes as follows:

$P(X$

Thus, the probability that a car driver can complete the transaction in less than 5 minutes is 0.4647.

Roger makes 70 gallons of pink paint by mixing red and white paint. He uses 21 gallons of red and 49 white. What percent of pink

klemol [59]

Answer:

30%

Step-by-step explanation:

In this case, we do not need to regard the amount of white paint. That information is just to confuse you.

The amount of red paint in the pink paint mixture can be represented by the fraction 21/70. All you have to do is simplify that to get 0.3, which is also represented as 30%. hope this helps :)

Ber [7]

Answer:

A1-60x+460

A2-50x+530

B-60x7+460

50x7+530

Step-by-step explanation:

A1 and A2-since x is equivalent to number of months we multiply the number of months then add it to the original cost to get how much total you get in the account.

B-you add 50 to 530 and 60 to 460 until they equal the same amount in this case its 7 times.
