Answer:
option: A and Option: B are correct.
Step-by-step explanation:
We are given a scatter plot we are asked to find which of the given statements hold true such that it's ranges describe the cluster in the scatter plot.
Clearly from the scatter plot we could see that:
The most of the points are between 6-12 years of experience in the scatter plot.
also the earnings are between $40,000 and $60,000 that covers most of the data.
Hence, option A. ( A. between 6 and 12 years of experience) and Option B ( B.
between $40,000 and $60,000 ) are correct.
Answer:
She would not have enough
Step-by-step explanation:
85x10=$850 divided by 12=70.8
Answer:
The slope of a horizontal line is zero
Step-by-step explanation:
All horizontal lines are parallel to the x-axis.
The x-axis has a zero slope.
All parallel lines have the same slope.
Therefore the slope of a horizontal line is zero.
This means there is no rise in y.
So rise over run will become:
0/run=0
The value of b in the equation 5/2b+(-25/2) is 1.
Answer:
W = 15900 ft.lb
Step-by-step explanation:
From the given information.
Consider y to be the distance from the ground towards the bucket of the cement.
At height y, suppose the bucket is lifted by Δy.
Then, the workdone can be = 500Δy + 0.5(75 - y) Δy
where;
The bucket of the cement = 500Δy
The remaining of the rope = 0.5(75 - y) Δy
However; the workdone (W) can be calculated as:
W = 15000 + 0.5 ( 2250 - 450)
W = 15000 + 900
W = 15900 ft.lb
