Answer:
140
Step-by-step explanation:
14 x 10 = 140
The expected completion time is μ = 40 weeks.
The random variable, X = 38 weeks (the probable time)
If the standard deviation is σ, then the z-score is z = (x - μ)/σ.
Let us test the given standard deviations.
When σ=1,
z = (38-40)/1 = -2
From standard tables,
P(x<=38) = P(z<=-2) = 0.0228 =2.3%
When σ=2,
z = (38*40)/2 = -1
P(x<=38) = P(z<=-1) = 0.1587 = 15.9%
When σ=4,
z = (38-40)/4 = -0.5
P(x<=38) = P(z<=-0.5) = 0.3085 = 30.9%
Answers:
z=1 => 2.3%
z=2 => 16% (approx)
z=4 => 31% (approx)
Answer:
1.5% of 4000 or 60

Answer:
205/6
Step-by-step explanation:
The question simply asks us to plug in 45 minutes into the given equation. In the graph, we see that y-axis is defined to be time. Therefore we set y=45 and solve for x.
45=-6/5x+86
-41=-6/5x (subtract 86 from both sides)
-41*(-5)=-6/5x*(-5) (multiply both sides by -5)
205=6x (divide both sides by 6)
205/6=x
Answer: The answers are in the steps please look carefully.
Step-by-step explanation:
To solve for each value input the value into the function and solve to find f(x)
A. f(-3) = 2(-3)^2 + 2
f(-3) = 2(9) + 2
f(-3) = 18 + 2
f(-3) = 20
B. f(6) = 2(6)^2 + 2
f(6) = 2(36) + 2
f(6) = 72+ 2
f(6) = 74
C. f(-1) = 2(-1)^2 + 2
f(-1) = 2(1) + 2
f(-1)= 2 + 2
f(-1) = 4
D. f(4) = 2(4)^2 + 2
f(4) = 2(16) + 2
f(4) = 32 + 2
f(4) = 34
