Answer: (I REDID THIS ANSWER)
$128
Step-by-step explanation:
20% off of $16,000 = $3,200
20% off of $3,200 = $640
20% off of $640 = $128
Answer= $128
Since it's a sample size, we use x, as the mean and s= standard deviation
_
Given: x =27, s = 2 and total sample = 32.
Probability that a recruit is at least 31 years old?
Let's calculate the Z score :
_
X - x 31 - 27
Z = ----------- → Z = -------- → Z = 2 (now look up in the Z score table,
s 2
Area (Z=2) =0.9772 , but Z ≥ 2 (at least) , then :
Area (Z≥2) = Area (Z≤ - 2) = 0.0228
P(≥31)= 0.0228
We use a conjecture that says that the perpendicular bisector of a chord in a circle passes through the center of the circle.
The distances of the two bisectors are the same so the chord lengths are the same.
b = half of 22.5 = 11.25
The answer to your question is 11.25.
