Answer:

Step-by-step explanation:
Z-score:
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:

You listen to the radio station for 1 hour, at a randomly selected time, and carefully observe that the amount of advertising time is equal to 17 minutes. Calculate the z-score for this amount of advertising time.
We have to find Z when X = 17. So



Those are positive numbers.
Those that are less than zero are called negative numbers.
Zero itself can be considered both, or neither.
AB- 3in.
BC- 5in.
CD- 7.2in.
sorry i don't really have an explanation I just looked at the picture and i guess imagined it in my head? lol sorry but here are the answers I hope that helps at least a little bit :))
Basically y would be whatever the number x is times 2, so -2 to the second power is -4, -1 to the second power is -1, 0 to the second power is 0, 1 to the second power is 1 and 2 to the second power is 4. now all you have to do is graph those points and you’re good!
