Answer:
A discrete function is a function with distinct and separate values. A continuous function, on the other hand, is a function that can take on any number within a certain interval. Discrete functions have scatter plots as graphs and continuous functions have lines or curves as graphs.

Answer:
65.54% probability that a battery lasts more than 4 hours
Step-by-step explanation:
Problems of normally distributed samples can be 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 a battery lasts more than 4 hours?
4 hours is 4*60 = 240 minutes.
So this is 1 subtracted by the pvalue of Z when X = 240.
has a pvalue of 0.3446
1 - 0.3446 = 0.6554
65.54% probability that a battery lasts more than 4 hours
