You would need to draw a graph or get some graph paper and plot those points. Then calculate the rise and the run. Rise is over the run. Then that is your slope. You get the rise by counting how many units up or down it takes to get to the point, and for the run, you count how many units across it is to get to the point. don't forget, if your units are going in a negative direction, then the number will be negative.
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

Hello!
We are given that each of the 5 alligators has 100 teeth. We can use the following equation to find the total number of teeth and, by extension, the total number of bite marks:
(100 teeth) × (5 alligators) = 500 teeth
We have now proven that the 5 alligators have a combined total of 500 teeth. Consequently, Sammy will have 500 bite marks.
I hope this helps!
Answer:
x = - 3
Step-by-step explanation:
Given
7(x + 2) = 2x - 1 ← distribute parenthesis on left side
7x + 14 = 2x - 1 ( subtract 2x from both sides )
5x + 14 = - 1 ( subtract 14 from both sides )
5x = - 15 ( divide both sides by 5 )
x = - 3
