Given:
Population mean, μ = 10
Population standard deviation, σ = 1.5
Random variable, x = 11.
By definition, the z-score is
z = (x - μ)/σ
= (11 - 10)/1.5
= 0.667
Answer: 0.667
Answer:
A
Step-by-step explanation:
I believe it is A because there is not any repeating X's. There is a repeating y which is 1. Therefore it is A.
Answer:
n = 15
Step-by-step explanation:
A straight line equals 180 degrees
Angle SWT is congruent to angle XWV meaning:
SWT (55 degrees) = XWV (55 degrees)
Set up an equation:
3n + 80 + 55 = 180
Combine like terms
3n + 135 = 180
Subtract both sides by 135 to isolate variable n
3n = 45
Divide both sides by 3 to isolate variable n
n = 15
It is less because 3 yards is 9 feet
Simply divide 53 by 18 to find that out. You can use a calculator (53/18) or mentally which would result to 2.94 times.
