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:
C. It’s APR because it’s less then it’s effective interest rate.
Answer:
Step-by-step explanation:
4) 35x + 28y =7*5*x + 7*4*y = 7(5x + 4y)
5) Cost of top = $9
Cost of 3 top = 9*3 = $27
Cost of skirt = $x
Cost of 3 skirt = 3x
Cost of 3 skirt and 3 top = 3x + 27
Cost of 2 skirt = 2x (as she bought 5 skirts)
Cost of her purchase = Cost of 3skirt &3 top and 2skirt
= (3x + 27) + 2x
= 5x +27
6) Cost of 5 nail polish bottle = 5p
Cost of two lip gloss tube = 2g
Cost of one gift bag = 5p + 2g
Cost of 8 gift bag = 8* ( 5p + 2g)
=8*5p + 8*2g
= 40p + 16g
It is 4 feet
Because it just is
