Answer:

B. -20

Step-by-step explanation:

8/d = -12/30

We can use cross products to solve

8 * 30 = d* -12

240 = -12 d

Divide each side by -12

240/-12 = -12d/-12

-20 = d

spin [16.1K]

Answer:800

Step-by-step explanation:

$Mean(\mu )=\$ 4300$

and $P(X>6140)=0.0107$

$P(X>x_0)=0.0107$

$P\left ( \frac{X-\mu }{\sigma}$

$P\left ( z$

$\frac{x-\mu }{\sigma}=InvNormal(0.9893)$

Using Z table to get InvNormal(0.9893)=2.30

$\frac{6140-4300}{\sigma}=2.30$

$\sigma =\frac{6140-4300}{2.30}=800$
