The distance will be given by the equation;
D=

D=

D=

D=

D=13 units
To solve for a, you must get a by itself on one side of the equation. Now, a is "joined" to m by multiplication. To "separate" them, use the inverse operation, division.
Divide both sides of the equation by m.
Answer:
The answer is 55 6/9, but when simplified, it is 55 1/3
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° .
