Determine the midpoint given 2<br> points.<br> (6,-10), (10,7)?
NISA [10]

Hey there! I'm happy to help!

To find the x-value of the midpoint, you add the x values and divide by 2.

6+10=16

16/2=8

And for the y value, you do the same thing but with the y values.

-10+7=-3

-3/2=-3/2

Therefore, our midpoint is (8,-3/2).

Have a wonderful day! :D

Pavlova-9 [17]

Answer:

b1 =~3.4

bo= ~ 82.8

(2)- ý=[82.8]+[3.4] x

(3)- The change in annual sales ($1000) for every year of experience is= 3.4

(4)-r^2=~ 0.847

Estimated annual sales= $110514

Step-by-step explanation:

(1)- b1 = 3.4606

=~3.4

bo = 82.8296

= ~ 82.8

(2)-

ý=[82.8]+[3.4] x

(3)-The change in annual sales ($1000) for every year of experience is= 3.4

(4)- r^2 = 0.84776

=~ 0.847

Percentage of the variation in annual sales can be explained by the years of experience

of the salesperson 84.7%.

Estimated annual sales

= 82.8296 + 3.4606 × 8 ($ 1000).

= 110.5144 ( $1000)

= $ 110514:4

= $110514
