Answer:

Emily has a higher relative score since her z-score is higher. This would mean she scored further above the mean than Xiaoyu.

Step-by-step explanation:

Find the z-scores by subtracting the score they got by the mean and then dividing by the standard deivation of their respective exams.

Xiaoyu:

z = $\frac{27 - 18}{6}$ = 1.5

Emily:

z = $\frac{720 - 500}{100}$ = 2.2

SOVA2 [1]

Answer:

see the explanation and the attached figure

Step-by-step explanation:

we have

$-2(x+1)=8$ ----> given

Divide by -2 both sides

$-2\frac{(x+1)}{-2} =\frac{8}{-2}$ ----> by Division Property of Equality

Simplifying

$x+1=-4$

Subtract 1 both sides

$x+1-1=-4-1$ ----> by Subtraction Property of Equality

Simplifying

$x=-5$
