$\dfrac{3y^2}{y+1}+\dfrac{3y}{y+1}=\dfrac{3y^2+3y}{y+1}=\dfrac{3y(y+1)}{y+1}=3y\to\fbox{B.}\\\\\\\dfrac{c+5}{3c+3}-\dfrac{4}{3c+3}=\dfrac{c+5-4}{3c+3}=\dfrac{c+1}{3c+3}=\dfrac{c+1}{3(c+1)}=\dfrac{1}{3}\to\fbox{D.}$

Answer:

The required probability is 0.0855

Step-by-step explanation:

Consider the provided information.

The daily revenue has mean $7200 and standard deviation $1200.

$\mu_{\bar x}=7200$

$\sigma=1200$

The daily revenue totals for the next 30 days will be monitored.

$\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}$

$\sigma_{\bar x}=\frac{1200}{\sqrt{30}}=219.089$

As we know $Z=\frac{\bar x-\mu_{\bar x}}{\sigma_{\bar x}}$

Substitute $\bar x=7500, \mu_{\bar x}=7200\ and\ \sigma_{\bar x}=219.089$ in above formula.

$Z=\frac{7500-7200}{219.089}=1.3693$

From the standard normal table P( Z >1.3693) = 0.0855

Hence, the required probability is 0.0855
