Answer: the answer is D
Step-by-step explanation:
This is because the x and y values constantly add two, making it exponential
<h3>
Answer: 40%</h3>
===================================================
Work Shown:
Subtract the values to get 2.1-1.5 = 0.6
Brianna is off by 0.6 liters
Divide that error by the true value 1.5 to get 0.6/1.5 = 0.40
Then move the decimal point 2 spots to the right to arrive at 40%
Therefore, the percent error is 40%
------------------
The formula you can apply is:

where
P = percent error
G = guess value (in this case it is 2.1)
T = true value (which is 1.5 in this case)
If we were to apply the formula, then we get:

Answer:
14/41=9
Step-by-step explanation:
6*3/7*3=18/21
1*7/3*7=7/21
18*7=126/441
126/9=14
441/9=49
Remark
The average is found by adding the total miles and dividing by the total number of hours.
Average
total distance = 52 + 64 + 49
Total distance = 165 miles
Total time = 1 + 1 + 1 = 3 hours.
Average = total distance/ total time
Average = 165 / 3 = 55 miles per hour.
