Use the pythagorean therom. 12 squared + 3 squared = x squared
So the answer is 12.4 feet
Answer:
x=-4/3
Step-by-step explanation:
Distribute
Like terms
Subtract from both sides
Divide both sides
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
