The monthly earnings of computer systems analysts are normally distributed with a mean of $4,300. If only 1.07% of the systems a

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

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

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

x = 375 and y = 6300. Option C.

Step-by-step explanation:

From the given data we need to find the value of x and y.

First, we will find out the ratio of area and the force.

$\frac{Area}{Force} = \frac{125}{1875} =\frac{150}{2250} =\frac{175}{2625}$ = $\frac{1}{15}$

So,

$\frac{x}{5625} = \frac{1}{15}$

or, x = $\frac{5625}{15}$ = 375

Again,

$\frac{420}{y} = \frac{1}{15}$

or, y = 420×15 = 6300

Hence,

x = 375 and y = 6300.

. What does the line y = 3x - 7 look like

Norma-Jean [14]

<span>y = 3x - 7

3 = slope
-7 = y intercept

This line would cross the y intercept at -7, and go up by 3 (slope). </span>
