Answer:

None of the above unless the equations have a typo

Step-by-step explanation:

With (0,-2), the x is 0. Plug that in on all equations and see which result in -2 as y. Since all of them do, try the next pair

(4,-1). Now plug 4 in to all the equations.

y=4*4-2 -- y=16-2=14

y=-4*4-2 -- y=-16-2=-18

y=2*4-2 -- y=8-2=4

y=-3*4-2 -- y=-12-2=-14

Neither apply

Answer:

81.8%

Step-by-step explanation:

Mean = $\mu = 40$

Standard deviation = $\sigma = 5$

Now we are supposed to find out what percent of the numbers fall between 35 and 50

$z = \frac{x-\mu}{\sigma}$

Substitute the values

$z = \frac{x-40}{5}$

Now for P(35<x<50)

Substitute x = 35

$z = \frac{35-40}{5}$

$z =-1$

Substitute x = 50

$z = \frac{50-40}{5}$

$z =2$

So, P(-1<z<2)

P(z<2)-P(z<-1)

=0.9772-0.1587

=0.8185

= $0.818 \times 100$

=81.8%

Hence 81.8% percent of the numbers fall between 35 and 50
