Answer:
<em>The required values are b=-6 and d=4</em>
Step-by-step explanation:
The graph corresponds to the function
We are required to find the values of b and d.
They can be found by using two points that are clearly visible on the graph. For example, the points (0,4) and (2,0) belong to the function. Substituting their values in the function:
Simplifying:
4 = d
d = 4
Now use the point (2,0):
Since d=4, and calculating
Simplifying:
Dividing by 4:
The required values are b=-6 and d=4
Part A: Scatter plot with best-fit line attached. You'll find the line to have equation (approximately)
The positive slope suggests that test scores and study time are directly are proportional.
Part B: Same as in a previous question you had posted. Pick two points on the provided line and compute the slope as best you can. For example, I might pick (2, 30) and (4, 40), which gives a slope of
and assuming the line passes through (2, 30) exactly, it would have equation
<u>ANSWER: </u>
Jack picked 10 ears of corn. The amount of corn left is ears of initial corn.
<u>SOLUTION: </u>
Given, Jack picked 10 ears of corn.
Now the total corn present is 10 ears.
He and two of his sisters ate two each.
Then, remaining corn = 10 ears – eaten corn
= 10 – 2 (by him) – 2 (by his first sister) -2 (by his second sister)
= 10 – 6 = 4
Now, the amount of corn left in fraction is remaining corn divided by initial corn.
Left over corn =
Hence, the amount of corn left is ears of initial corn.
