If there are 30.48cm in a foot and 12cm represents 102 feet then 12 cm represents 3109cm or 12:3109. Divide both sides by 12 to get the scale and it is: 1:259, the scale is 259.
Hope this helps :)
Answer: Not unusual.
Step-by-step explanation:
We know that the z-scores lower than -1.96 or higher than 1.96 are considered as unusual.
Given : Sample size : n= 65
Sample mean = 
Standard deviation : 
Formula for z-score : 
At x= 213

Since , -1.96< 0.17 <1.96
It means the probability of a sample mean being greater than 213 is not unusual.
Answer:
Solve for x by simplifying both sides of the equation, then isolating the variable
So your Answer is x = 2 Hope this helps :)

Answer:
25/32 chapter per hour
Step-by-step explanation:
(5/8)/(4/5)=x/1
cross product
4/5*x=(5/8)(1)
4/5x=5/8
x=(5/8)/(4/5)
x=(5/8)(5/4)
x=25/32
A and B are the correct options
