Answer:
Step-by-step explanation:
Part 1
P(z < -1.45)
Using the z score table
P =
Part 2
We solve using z score formula
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
a) P(X >52)
x = 52
Mean = 60
Standard deviation = 8
z = 52 - 60/8
z = -1
P-value from Z-Table:
P(x<52) = 0.15866
P(x>52) = 1 - P(x<52) = 0.84134
b) P(48 < x < 64)
Answer:
yes!
Step-by-step explanation:
if it has a 90° angle it is a right triangle :)
Answer:
Step-by-step explanation:
Multiply both sides of the equation by 5.
5 · 
· 
5 · 4
Simplify both sides of the equation.
Subtract 10 from both sides of the equation.
Divide each term by 2 and simplify.

Substitute x for 6
Multiply 3 · 6
Add 18 + 9
Divide 
÷ 27
9 = 9
