Basile [38]
Remember that the additive inverse are two equal numbers (or expressions) but with different signs.
 We have then, that according with the coment below:
 (3a2 - 5ab + b2) - (-3a2 + 2b2 + 8ab)
 the additive inverse is:
 (3a2 - 2b2 - 8ab) Note that is the same expression that
 (-3a2 + 2b2 + 8ab)
 but with different signs.
 Answer:
 the additive inverse of the polynomial being subtracted is 
 (3a2 - 2b2 - 8ab)

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
