Answer:
The percent error of Heather's calculation is <u>8%</u>.
Step-by-step explanation:
Given:
Heather measures the temperature of her coffee to be 133.4 degrees fahrenheit. It is actually 145 degrees fahrenheit.
Now, to find the percent error of Heather's calculation.
The temperature of coffee Heather measures = 133.4° F.
Coffee's actual temperature = 145° F.
So, to get the measurement in error we subtract the temperature of coffee Heather measures from coffee's actual temperature:
Now, to get the percent error:
Therefore, the percent error of Heather's calculation is 8%.
Answer:
5
Step-by-step explanation:
Since we are dealing with a volume problem (3 dimensions) when you increase the radius by a factor of 2, you increase the volume by a factor of 2^3 or 8
So, the larger sphere has a volume 8 times greater than the smaller sphere.
Answer:
(17y/8) - 101 or (17y - 808) / 8
Step-by-step explanation:
Please enclose the fractional coefficient 1/8 inside paretheses:
(1/8)y + 17 + 2y - 118.
Now combine like terms. (1/8)y + 2y comes to (1/8)y + 16y/8 = (17/8)y.
We thus have (17/8)y + 17 - 118. Leaving (17/8)y alone, evaluate 17 - 118:
(17y/8) - 101
You could leave your answer in this form, or combine the terms using the LCD 8:
17y - 808
--------------
8
There is absolutely no correlation between the variables.
