Answer are in pictures below
7v-v=12 subtract v from 7v to get 6v
6v=12 divide 12 by 6 to find variable
v=2
Answer: The mean of the frequency distribution is 51.7°.
The computed mean 51.7° is greater than the actual mean 50.7° .
Step-by-step explanation:
The given table :
Low Temperature (°F) Frequency Mid -value
Class interval f x fx
40-44 2 42.5 85
45-49 7 47.5 95
50-54 9 52.5 105
55-59 5 57.5 115
60-64 1 62.5 25

The computed mean 51.7° is greater than the actual mean 50.7° .
*Tenths and *hundredths
The digit in the tenths place is 10 times the digit in the hundredths place. hope this helps.
