I believe it's graph C! I hope it will help you...
I’d have to say rate of change.
Answer:
No. Hardy should have multiplied by the scale factor to find the missing length.
Step-by-step explanation:
Given equation is
Now we can compare it with general form of quadratic equation (
)
a = 3 , b = 3 and c = 4
Now we can apply quadratic formula which is given as
Now we can plugin value of a , b or c
In general we know
So we can write
So
So
or
Answer:
The answer is given below
Step-by-step explanation:
The mean (μ) = 21.2 minutes and the standard deviation σ = 3.5 minutes.
the oil-change facility will perform 45 oil changes between 10 A.M. and 12 P.M, therefore the sample size n = 45
there be a 10% chance of being at or below. From the normal distribution table, The z score corresponding to a probability of 10% (= 0.1) is -1.28.
z = -1.28
To calculate the mean oil-change time, we use the formula:
