Step-by-step explanation:
Answer:
The function that models the data in this table would be a linear function.
Step-by-step explanation:
161-52=9
7-14=3
9/3=3
52-43=9
14-11=3
9/3=3
Answer:
4.75% probability that the battery will last more than 9 hours before running out of power
Step-by-step explanation:
Problems of normally distributed samples are solved using 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 problem, we have that:

What is the probability that the battery will last more than 9 hours before running out of power g
This is 1 subtracted by the pvalue of Z when X = 9. So



has a pvalue of 0.9525
1 - 0.9525 = 0.0475
4.75% probability that the battery will last more than 9 hours before running out of power
2x-6=3x+1-x-7
Simplify the right side by combining like terms:
2X - 6 = 2X - 6
Because both sides of the equation are the same any value of X will make this true.
