You can use normalCdf(.72,.78,.75,.01) to find the answer or if you standardize your numbers (z scores) normalCdf(-3,3,0,1).
Answer:
1 min 45 sec
Step-by-step explanation:
First convert 14 min to seconds.
14 x 60 = 840s
Now we can use ratios to find the answer
840s : 800m
Divide both sides by 8
105s : 100m
105s is 1 minute and 45 seconds
Answer:

Step-by-step explanation:
Call 
Now, 

This is the inverse of the given function.
You can cross - verify it by substituting a point, say, 
We see that the point satisfies both the equations.
Answer:
Step-by-step explanation:
Find the slope of the line
(x₁ , y₁) = (6 , 8) & (x₂ , y₂) = (0 , 5)

m = 1/2 ;(x₁ , y₁) = (6 , 8)
y - y₁ = m(x - x₁)

C.
If you spin it around 180 degrees from the center, it's the same object
