The actual height of Karen = 142 cm
The measured height of Karen = 147 cm
We have to determine the approximate percent error of Karen's measurement.
The difference in the heights = 147 cm - 142 cm = 5 cm
So, Error percentage =
=
= 3.52
= 3.5 (approximately)
So, the approximate percent error of Karen's measurement = 3.5%
The percentage of dogs who didn't try to bite the groomer is; 65%.
<h3>What is the percentage of dogs that did not try to bite the groomer?</h3>
If follows from the task content that the number of dogs is 300 of which, 0.35 faction of the whole tried to bite the groomer.
Hence, the faction that did not try to bite the groomer is; 0.65 which corresponds to 65% when expressed as a percentage.

Answer:
Part a. The graph does not model a proportional relationship.
Part b. The values in table model a proportional relation.
3.5 minutes per mile.
Step-by-step explanation:
Part a.
The graph shown in the question representing Janet's data is not a straight line although it passes through the origin.
That is why the rate of change of distance with time is not constant.
Therefore, the graph does not model a proportional relationship.
Part b.
If we plot the data in the table using distance in miles along the y-axis and time in minutes along the x-axis, then we will get a straight line passing through the origin.
So, the values in the table model a proportional relation.
Now, Tarik's unit rate in minutes per miles will be minutes per mile. (Answer)
Answer:
84.4 m
Step-by-step explanation:
We are given that
The new angle,
Slop of the present bank=210 ft
We have to find the horizontal distance into the bank must they dig.
The horizontal distance they have to dug=191.8-107.4=84.4 m
28 - 6n + 7.(5n - 2) - 2n
28 - 6n + 35n - 14 - 2n
28 - 14 + 35n - 6n - 2n
14 + 28n
14.(2n + 1)
