Answer:

x = $\frac{71}{3}$

Step-by-step explanation:

1. Simplify/distribute each side.

$4(2)(-7)+3(3)(-1)=3(2-x)$

$4(2)(-7)+3(3)(-1)=(3)(2)+(3)(-x)$

$-56+-9=6+-3x$

2. Flip the equation around.

$-3x+6=-65$

3. Subtract 6 to balance the equation.

$-3x+6-6=-65-6$

$-3x=-71$

4. Divide each side by 3. We know they are in the same fact family.

$\frac{-3x}{-3} = \frac{-71}{3}$

Consider the probability distribution of x, where x is the number of job applications completed by a college senior through the

Oksi-84 [34.3K]

The expected number out of 1000 selected college seniors that completed 1 job application through the career centers is given by 0.011 x 1000 = 11 which is close to 14.

The expected number out of 1000 selected college seniors that completed 2 job application through the career centers is given by 0.115 x 1000 = 115 which is far away from 15.

The expected number out of 1000 selected college seniors that completed 3 job application through the career centers is given by 0.123 x 1000 = 123 which is close to 130.

Therefore, the result that would be suprising is "15 seniors completed 2 job applications through the career center."
