(-7/8) / (-1 2/5) = (-7/8) / (-7/5) = (-7/8) * (-5/7) = 5/8
Since D=MV, we can infer that M=D/V
That is your equation----------------^
Answer:
Her z-score is 2.03.
Step-by-step explanation:
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
Michelle’s height is 1.758 meters. What is her z-score?
Michelle's is a woman.
The average height of women is 
and the standard deviation is 
This is Z when X = 1.758. So
Her z-score is 2.03.
Answer:-10
Step-by-step explanation: The slope-intercept form is
y
=
m
x
+
b
y
=

Answer:
x+2y=- 7
x-2y =9
Step-by-step explanation:
Solving Steps
2x+4y=-14
x-2y=9
Divide both sides
(2x+4y) ÷2=-14=2
{x-2y=9
Remove the parentheses
Divide
2x÷2+4y÷2=-7
x-2y =9
Divide
Solution
x+2y=- 7
x-2y =9
