Step-by-step explanation:
they can all divide 72
Answer:
/2
Step-by-step explanation:
/
=1.2422
/2=0.66 <-- not matching with the top expression.
/2=1.11<--not matching with the top expression.
/2=1.2422<-- matches!!
/3=0.91<-- not matching with the top expression.
Y = 1/2 +7

Using the normal distribution, it is found that 25.14% of the batteries will last more than 420 hours.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
In this problem, we have that the mean and the standard deviation are given, respectively, by:
.
The proportion of the batteries will last more than 420 hours is <u>one subtracted by the p-value of Z when X = 420</u>, hence:


Z = 0.67
Z = 0.67 has a p-value of 0.7486.
1 - 0.7486 = 0.2514.
0.2514 = 25.14% of the batteries will last more than 420 hours.
