As there are no given data to work with in this given problem, allow me to generally describe the steps involved in going about this type of problems.
If we are asked about rate, we simply divide the number of fuels (in gallons) used by the racing dragster by the time (in second) it takes for it to be consumed.
Answer:
A) 3x+2
Step-by-step explanation:
Factor the numerator and denominator and cancel the common factors.
The answer would be 1/4
Answer:
The mean is 24.205
Step-by-step explanation:
Firstly, we need to get the z-score
From the question, the probability we have is the probability that commuters take more than 22 minutes to commute one-way
So the probability we had was;
P( x > 22)
So we need the z-score corresponding to 63.70% or simply 0.637
We can use the standard normal distribution table to get this
Mathematically, from the standard normal distribution table this is -0.35
z-score = (x- mean)/SD
-0.35 = (22-mean)/6.3
22-mean = -2.205
mean = 22 + 2.205 = 24.205
