Answer: 1.25
Step-by-step explanation:
Given: A college-entrance exam is designed so that scores are normally distributed with a mean
= 500 and a standard deviation
= 100.
A z-score measures how many standard deviations a given measurement deviates from the mean.
Let Y be a random variable that denotes the scores in the exam.
Formula for z-score = 
Z-score = 
⇒ Z-score = 
⇒Z-score =1.25
Therefore , the required z-score = 1.25
The answer would be 242.8
It will not go up because in order to round up it must be 5 or above.
2x-4 D it can be your answer if you multiply correctly and you do it
Step-by-step explanation:
Create a right triangle with the hypotenuse = 2400in (same as 200ft) and angle from horizontal =15 degrees
you can create the equation to find the opposite line (y-value)
2400sin(15) =
621 in
