Answer:

$136.50

Step-by-step explanation:

Time and a half = 13.00 + (13 × 1/2)

Time and a half = 13.00 + 6.50

Time and a half = $19.50

If he works 7 hours of overtime, and overtime means getting paid time and a half, we would multiply 7 hours by $19.50 to find the total amount he was paid

7 × 19.50 = 136.50

In overtime, he was paid $136.50

Find z if X=27, μ=20, and α=3.4. Round to the nearest hundredth if necessary.

Scrat [10]

Answer:

A. $Z=2.06$

Step-by-step explanation:

We want to find the Z-score of $X=27$ if the population mean is $\mu=20$ ,and the population standard deviation is $\sigma=3.4$ .

We use the formula:

$Z=\frac{X-\mu}{\sigma}$

We substitute the values to obtain:

$Z=\frac{27-20}{3.4}$

$Z=\frac{7}{3.4}$

$Z=2.06$

The correct answer is A.
