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
Formula for the area of a face of a cube: A = length x width
Let's find the area of one face.
A = 5 x 5
A = 25
Now, let's multiply the area of one face by 6 because a cube has 6 faces.
25 x 6 = 150
A = 150 square centimeters
Hope this helps! :)
Answer:
Step-by-step explanation:
Given
Required
Determine Y'
Y' can be solved by multiplying the scale factor by Y
i.e.
For, the x coordinates.
Where
For the y coordinates:
Where
Hence:
Answer:
r = 20
Step-by-step explanation:
-4 = r/20 - 5
-4 + 5 = r/20 - 5 + 5
1 = r/20
1 * 20 = r/20 * 20
r = 20
If 9 is the radius and 20 is the height then it would be 5089.4 cm^3
