Answer:
A.) = 6
If RE = 12, then RD = 6
B.) = 10
If BR = 10, then BE = 10
C.) = 16
If BD = 8, then BK = 16
D.) = 30*
<m9 = 90*, and <m2 = 60*, so add them and subtract from 180*, you are left with <m1 = 30*
E.) = 60*
If <m2 = 60*, then <m3 = 60*
F.) = 90*
It`s a 90* angle because BK and RE and perpendicular
G.) = 60*
If <m1 = 30*, then multiply by two because it is symmetrical
I would show all my work but you seem to be in a rush. Hope this helps!
Answer:
(1)-
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

Final answer: C
Answer: this is hard I hate math sorry
Step-by-step explanation:
:(
Answer:
β = 140 - α
we know that the "missing" angle is 40° since 40 + 140 = 180
we also know that the total sum of angles in a triangle is 180
so β = 180 - 40 - α
or β = 140 - α
