Answer:
0
Step-by-step explanation:
The slope formula is (change in y)/(change in x)
since the numerator (change in y) is 0, the slope will be 0
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
Your question is:

Then, the above formula equate:

Factor out 8 from the numerator we get:

Factorization of the denominator:

Simplifying the numerator and the denominator by (u-9) we get:
Answer:
Step-by-step explanation:
first step is to multiply
-5(2x-2)=-10x+10
-10x+10-7x-8=-17x+2
Answer:
6
Step-by-step explanation:
The outlier is 67.
The mean with the outlier is: 115
(112+ 118 + 120 +67 + 128 + 119 + 121 + 124 + 126) ÷ 9
The mean without he outlier is: 121
(112+ 118 + 120 + 128 + 119 + 121 + 124 + 126) ÷ 8
So, 121 - 115 = 6
