Answer:
f(q)=1.77q+47,738
Step-by-step explanation:
Answer:
a) 9.56%
b) 0.0019
Step-by-step explanation:
a) Find the z-scores.
z = (x − μ) / σ
z₁ = (-0.0050) / 0.0030
z₁ = -1.67
z₂ = (0.0050) / 0.0030
z₂ = 1.67
Find the probability using a chart or calculator.
P(Z < -1.67 or Z > 1.67) = 2 P(Z < -1.67)
P(Z < -1.67 or Z > 1.67) = 2 (0.0478)
P(Z < -1.67 or Z > 1.67) = 0.0956
b) Use a chart or calculator to find the z-score.
P(Z < -z or Z > z) = 0.01
P(Z < -z) = 0.005
z = 2.576
Find the standard deviation.
z = (x − μ) / σ
2.576 = (0.0050) / σ
σ = 0.0019
I got -6/25 Sorry I can't really explain this try web2.0calc.com it helps alot with math.
56 + 32 = (8 x 7) + (8 x 4) = 8(7 + 4) (Answer C)
Answer:
see the explanation
Step-by-step explanation:
we know that
A mixed number is equal to sum a integer plus a fraction less than 1. The result is a fraction where the numerator will be always greater than the denominator (This fraction is called an improper fraction)
Example
----> a mixed number
a is a integer
b/c < 1
so
Adds the integer plus the fraction
---> an improper fraction
