Step-by-step explanation:
step 1
Find the volume of the snow
Convert inches to feet
1 ft=12 in
8 in=8/12=(2/3) ft

step 2
Find the mass of the snow
Multiply the density by the volume


Answer:
16% probability that the facility needs to recalibrate their machines.
Step-by-step explanation:
We have to use the Empirical Rule to solve this problem.
Empirical Rule:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
What is the probability that the facility needs to recalibrate their machines?
They will have to recalibrate if the number of defects is more than one standard deviation above the mean.
We know that by the Empirical Rule, 68% of the measures are within 1 standard deviation of the mean. The other 100-68 = 32% is more than 1 standard deviation from the mean. Since the normal distribution is symmetric, of those 32%, 16% are more than one standard deviation below the mean, and 16% are more than one standard deviation above the mean.
So there is a 16% probability that the facility needs to recalibrate their machines.

Step-by-step explanation:
Hi there!
Let
represent "the number".
A number added by 7 is the same as that number times four minus eleven.
A number added by 7 ⇒ 
Is the same as ⇒ 
The number times four ⇒ 
Minus eleven ⇒ 
I hope this helps!
