The hypotenuse


= 53 cm
The meaning of this problem is that with 7 nurses they can only hire D=13.25
<h3>What is the meaning of this problem.?</h3>
Generally, the equation for the model is mathematically given as

Therefore,


Also

Equations 1 and 2

.sub D=(60N)/4

N=6.67
N=7
solve for D
D=(60(7))/4
D=13.25
In conclusion, with 7 nurses they can only hire D=13.25

Answer:
27,361.
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:

Ninety-five percent of all students at private universities pay less than what amount?
This is the 95th percentile, that is, X when Z has a pvalue of 0.95. So X when Z = 1.65.




So the answer is 27,361.
I’m assuming that you only need the answer to the last one but let me know if I’m wrong :)))
I believe C would be 23.6
In this equation, there is nothing to solve for. However, the expression

is the Pythagorean theorem. If there is a right triangle, then when the lengths of two shorter legs (a and b) are added together, and then square rooted, you get c, which is the hypotenuse.
Hope this helps!
