Answer:
(SA - 2s^2)/4s
Step-by-step explanation:
Assuming you mean 2s^2
SA = 2s^2 + 4sh
4sh = SA - 2s^2
h = (SA - 2s^2)/4s
Answer:
59.48%
Step-by-step explanation:
To determine the probability you have to calculate the z score which is equivalent to the number of standard deviations you are from the mean.
x is the value you want to know its probability
μ is the mean
σ is the standard deviation
A z score of -0.24 means you are 0.24 standard deviation at the left of the mean, the probability associated to a z of -0.24 can be found in a z table and it is 40.52%.
That probability cover the minimum value until 12 minutes, so the probability to need more than 12 minutes is 100 - 40.52 = 59.48%
Answer:
The answer is 5+2h because it is $2 per hour so 2h and $5 per day. it does not have a variable for $5 per day
28 is False
29 is True
