Given:
μ = 55 in, population mean
σ = 6 in, population standard deviation
Part (a)
x = 48 in, the random variable
Calculate the z-score.
z = (x - μ)/σ
= (48 - 55)/6
= -1.667
From standard table, obtain
P(X < 48) = 0.12167
Answer: 0.1217 (tyo 4 dec.places)
Answer:
D. Omar's transaction involves more money, because |-15| is greater than |10|.
Step-by-step explanation:
The absolute value of a number is simply the magnitude or numerical value of a number while ignoring any sign attached to it. For example, given that x is a real number, absolute value of x, |x| = x. The absolute value of x does not take account of any sign attached to it.
Thus:
The absolute value of Omar's transaction is given as |-15| = 15.
While that of Jake is |10| = 10.
15 is greater than 10.
Therefore, we can conclude that:
"Omar's transaction involves more money, because |-15| is greater than |10|."

Answer:
48 degrees
Step-by-step explanation:
First, calculate the supplementary angles for 99 degrees and 129 degrees. You would get 81 degrees and 51 degrees respectively.
Then add those two numbers and you'll get 132 degrees. Since a triangle equals 180 degrees, use: x + 132 = 180. You would get x as 48.
