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.
Answer:
its number d. my 1/8 brain cell said so.
Step-by-step explanation:
If f(x)=6x+2,
f(x+3)=6(x+3)+2
f(x+3)=6x+18+2
f(x+3)=6x+20
Answer:
We can see that point
represent the amount of calories she/he has had in the last 2 minutes. Therefore, to find how many she has had per minute follow like so:
2:20
2/2:20/2
1:10
She has 10 calories per minute
Step-by-step explanation:
The answer is 13.
You can evaluate this by substituting x for 5 in the expression.
4x-7
4(5)-7
20-7
13
