Answer:
The answer is : 0.0597
Step-by-step explanation:
Population mean = μ = 80
Standard deviation = σ = 20
Sample = N = 60
σ_mean = σ/√N
= (20)/√(60) = 2.582
Now we will find z1 and z2.
z1 = {(84) - μ}/σ_mean = 
z2 = {(88) - μ}/σ_mean = 
Now probability that the sample mean will be between 84 and 88 is given by:
Prob{ (1.549) ≤ Z≤ (3.098) } = (0.9990) -(0.9393) = 0.0597
"centi" means "hundredth". Think "cent" as in "penny". There are 100 cents or 100 pennies in a dollar.
That helps me remember that
1 meter = 100 centimeters
The original "1 meter or 105 centimeters" turns into "100 centimeters or 105 centimeters"
At this point, it is clear that 105 is larger than 100. So 105 cm is larger than 1 meter.
Hi there!
For a line to be PARALLEL, it must contain the same slope.
The given line has a slope of 4, so we can use the point-slope formula to solve:

y1 = y-coordinate of given point
x1 = x-coordinate of given point
m = slope
Plug in the values:

Simplify:
