Answer:
2/13
Step-by-step explanation:
Cdgfsggdehfetgfrhfer
Her credits need to be AT LEAST EQUAL TO OR GREATER THAN 144 (credit hours) so we can eliminate choices B and D.
She already completed 4 semesters in which she receives 15 credit per semester.
This expression can be written as 4(15).
She needs to do a certain remaining hours of credit which can be represented by c and only c without any other coefficient.
So, the most reasonable choice here is A.
Answer:
3x^7+2x^6-5x^5
Step-by-step explanation:
(3x^7-4x^5+3)+(2x^6-x^5-3)
3x^7-4x^5+3+2x^6-x^5-3
3x^7+2x^6-4x^5-x^5+3-3
3x^7+2x^6-5x^5
Answer:
The probability that the man is greater than 74 inches is 0.1587
Step-by-step explanation:
The required probability is found by evaluating the area under the corresponding distribution curve for the corresponding values
The standard normal variate factor (Z) is given by
![Z=\frac{x-\bar {X}}{\sigma }](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7Bx-%5Cbar%20%7BX%7D%7D%7B%5Csigma%20%7D)
where
is mean of the data
is the standard deviation of the data
Thus corresponding to x = 74 the Z factor equals
![Z=\frac{74-70}{4}=1](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7B74-70%7D%7B4%7D%3D1)
Using the standard normal distribution table corresponding to mean of 70 and deviation of 4 the area under the curve corresponding to Z = 1 equals
0.1587
