Answer: The z-score = 2.46
Step-by-step explanation:
Given: sample size : n= 10
Population mean : 
population standard deviation : 
Sample mean : 
Formula to calculate z :

Substitute all values, we get

Hence, the z-score = 2.46
Answer:
y = 4x + 1
Step-by-step explanation:
Find slope, rise over run

find y intercept by plugging in one of the coordinates in y=mx+b, including m=4
-7 = 4(-2) + b
1 = b
Answer:
z/y
Step-by-step explanation:
the quotient of z and y
this does no require any work just understand the question
the quotient of z and y means z divide by y
z/y
Answer: C.
Both functions are decreasing, but function f is decreasing at a faster average rate on that interval.
Step-by-step explanation:
Let first work out g(x)
When x = 0
g(x) = 75
When x = 1
g(x) = 75( 1 - 50%)
g(x) = 75(0.5) = 37.5
Which is less than 43
With this, we can conclude that:
Both functions are decreasing, but function f is decreasing at a faster average rate on that interval.
Answer:
14
Step-by-step explanation:
Divide 140 by 10. That will get you 14. 10% of 140 is 14
