Hi! So, a ratio is basically comparing one amount to another. And you do that by putting the first number, a colon, and the second number.
So, it's asking for oranges to apples. There's 60 oranges, and 18 apples. So you write:
60:18
The absolute error is 4 cu. in. and the relative error is 10%.
To find the absolute error, subtract the actual value from the estimate:
36 - 40 = -4
With absolute error, we ignore negative signs, so the absolute error is 4 cu. in.
To find the relative/percent error, divide the absolute error by the actual value:
4/40 = 0.1
Converting this to a percent, 0.1(100) = 10%
9514 1404 393
Answer:
14
Step-by-step explanation:
Assuming the grade is proportional to the number of problems answered, we have ...
a/20 = 70/100
a = 20(0.70) = 14 . . . . multiply by 20
