Answer:
4.01% probability that the battery will break down during the warranty period
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:

a. What is the probability that the battery will break down during the warranty period
Warranty of 2 years = 24 months. So this is the pvalue of Z when X = 24.



has a pvalue of 0.0401
4.01% probability that the battery will break down during the warranty period
Answer:
The GCF of 27 and 72 is 9
Step-by-step explanation:
prime factorization of 27 is 3*3*3
prime factorization of 72 is 2*2*2 by 3*3
3*3 is in both, and so we need to multiply that to get our GCF. 3*# is 9, so the GCF of 27 and 72 is 9

While setting up a fireworks
display, you have a tool at the top of the
building and need to drop it
to a coworker below. Given the equation:
h(t) = -16t^2 + h0
h = 84 feet
it will take the tool to fall
to the ground 2.29 time unit
-84 = -16t^2 – 0
<span>t = 2.29 time unit</span>
