Answer:
2.1 in
Step-by-step explanation:
I only wrote the expression 7n = 15. Then figured it out from there. I ended up with n = 2.1
I'm sorry if this doesn't help. I tried my best to solve it. Hope this leads you to the right answer ^^
Answer:
x = 63.6
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 and also the area to its left. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X, which is the area to its right.
In this problem, we have that:

Find a value of x that has area 0.01 to its right
This is x when Z has a pvalue of 1-0.01 = 0.99. So it is X when Z = 2.3267.




So x = 63.6

Answer:
Step-by-step explanation:
What variable are you solving for?
In this question , we have to find, which option represents inverse functions.
Let's check out option b
Let it be y
So we have

Switching x and y and solving for y,

Performing cross multiplication

Combining like terms


Which is same as of the other function.
So correct option is b .
