The owner of a computer repair shop has determined that their daily revenue has mean $7200 and standard deviation$1200. The dail
matrenka [14]

Answer:

The probability that the mean daily revenue for the next 30 days will exceed $7500 is 0.0855

Step-by-step explanation:

It has been given that

\mu=7200\\\\\sigma=1200,n=30,x=7500

Now, the formula for z-score of a normal distribution is given by

z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}

Substituting the known values, we get

z=\frac{7500-7200}{\frac{1200}{\sqrt{30}}}

Simplifying, we get

z=\frac{300}{219.1}\\\\z=1.369238

Now, we have to find that the daily revenue for next 30 days will exceed $7500.

Thus, we have to find

P(z>1.369238)

From the normal distribution table, we have

P(z>1.369238)= 0.0855

Therefore, required probability is 0.0855

A blouse that is size x in country A is size​ s(x) in country​ B, where ​s(x)x. A blouse that is size x in the country B is size
MakcuM [25]

Answer:

f(x) = [k(x): x = s(x) = t(x)]

Step-by-step explanation:

To make the question clearer, rewrite;

A blouse that is size x in country A is size s(x) in country B.

s(x) = x

A blouse that is size x in country B is size t(x) in country C.

t(x) = x

Find a function f(x) that will convert blouse sizes in country A to blouse sizes in country C.

f(x) = [k(x): x = s(x) = t(x)]

Interpretation:

f of x is equal to k of x such that x is equal to s of x which is also equal to t of x.

Where the other blouse sizes are represented by k(x) or as a function of the given size x.
