Ok, so i got 144 cubic cubic meters by multiplying 6 by 6 by 4. Tell me if it's correct because i'm not the best at Math, but I checked and rechecked it. <span />
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

Answer: c
Step-by-step explanation: Y=4 will result in a straight line across 4 from the y axis. Y=4x is a linear equation for which result in a straight constant like. Y=4x2 represents a parabola equation and will create one. Y=4x3 represents a cubic equation
