In the given question, we have a graph given, and on the basis of that graph, we have to find the interval where the graph is increasing, decreasing or constant .
As we see in the graph, that the graph goes up and up only, no where it goes down or it is constant.
So the graph is increasing on all real numbers and decreasing nowhere.
Answer:
0.0475 = 4.75% probability that a randomly selected complaint takes more than 15 minutes to be settled.
Step-by-step explanation:
Normal Probability Distribution
Problems of normal distributions can be solved using the z-score formula.
In a set with mean
and standard deviation
, the z-score 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 p-value, we get the probability that the value of the measure is greater than X.
Mean of 10 minutes and a standard deviation of 3 minutes
This means that 
Find the probability that a randomly selected complaint takes more than 15 minutes to be settled.
This is 1 subtracted by the p-value of Z when X = 15, so:



has a p-value of 0.9525.
1 - 0.9525 = 0.0475.
0.0475 = 4.75% probability that a randomly selected complaint takes more than 15 minutes to be settled.
Answer:
72%
Step-by-step explanation:
Because you add 10 and 4 to get 14.
Next minuse 14 from 50 to get 36.
Then divide 36 and 50 to get 0.72.
Finaly move your decimal to get your percent
Answer:
1 yes 2 no 3 no
Step-by-step explanation:
You are adding 9/3 each time
so 2/3, 11/3, 20/3, 29/3, 38/3, 47/3
hope this helps
