-7x + 6 =27
subtract 6 from both sides
-7x =21
divide both sides by -7
x= -3
I’m pretty sure the distance would be (2,5)
5 1/2 ft equals 66 inches
Answer:
false
Step-by-step explanation:
Answer:

Using the frequency distribution, I found the mean height to be 70.2903 with a standard deviation of 3.5795
Step-by-step explanation:
Given
See attachment for class
Solving (a): Fill the midpoint of each class.
Midpoint (M) is calculated as:

Where
Lower class interval
Upper class interval
So, we have:
Class 63-65:

Class 66 - 68:

When the computation is completed, the frequency distribution will be:

Solving (b): Mean and standard deviation using 1-VarStats
Using 1-VarStats, the solution is:
