Answer:
Step-by-step explanation:
I'm going to guess that the question is "How do you represent the distance between the left and right sides?"
The red dots are closed which means that the end points are included.
5 ≤ x ≤ 8
The length is 8 - 5 = 3
Answer:
B - Spider-Man
Step-by-step explanation:
The answer would be 101/20
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
