Answer:
(A) 0.0013
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:
The probability that telephone call selected a random will last more than 15.5 min is most nearly
This is 1 subtracted by the pvalue of Z when X = 15.5.
So
has a pvalue of 0.9987
1 - 0.9987 = 0.0013
So the correct answer is:
(A) 0.0013
Answer:
<u>Option d</u>
Step-by-step explanation:
The graph of an inverse relation is the reflection of the original graph over the identity line, y = x.
So, the graph which contain the line y = x is the correct graph
Graph a ⇒ includes a function, its inverse, and the line x = 1
Graph b ⇒ includes a function, its inverse, and the line y = -x
Graph c ⇒ includes a function, its inverse, and the line y = 1
Graph d ⇒ includes a function, its inverse, and the line y = x
<u>So, the answer is option d</u>
Answer:
A
Step-by-step explanation:
if staci has flown 6 times as many miles as joe, you would mulitply the number of miles joe has flown by 6, or A
According to the results of the experiment, the chances of her falling 5 of the next 7 times would be 4/19 or 21.1% chance. This answer is strictly based on the fact that in his experiment, it happened 4 times out of the 19 times he attempted it.
