Water use in the summer is normally distributed with a mean of 311.4 million gallons per day and a standard deviation of 40 mill
r-ruslan [8.4K]

Answer: 0.965

Step-by-step explanation:

Given : Water use in the summer is normally distributed with

\mu=311.4\text{ million gallons per day}

\sigma=40 \text{ million gallons per day}

Let X be the random variable that represents the quantity of water required on a particular day.

Z-score : \dfrac{x-\mu}{\sigma}

\dfrac{350-311.4}{40}=0.965

Now, the probability that a day requires more water than is stored in city reservoirs is given by:-

P(x>350)=P(z>0.965)=1-P(z

We can see that on comparing the above value to the given P(X > 350)= 1 - P(Z < b) , we get the value of b is 0.965.

Which expression is equivalent to 3(4m - 2) - 2(m + 5)
tangare [24]

Answer:

A. 10m - 16

Step-by-step explanation:

First, distribute 3 to all terms within the corresponding parenthesis, and -2 likewise:

3(4m - 2) =

3 * 4m = 12m

3 * -2 = -6

3(4m - 2) = 12m - 6

-2(m + 5) =

-2 * m = -2m

-2 * 5 = -10

-2(m + 5) = -2m -10

Combine like terms:

12m - 6  -2m - 10

12m - 2m - 6 - 10

(12m - 2m) + (-6 - 10)

10m - 16

A. 10m - 16 is your answer.
