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

Step-by-step explanation:
If you take 72 inches and convert it into yards you get 2 yards.
(divide the length value by 36. so 72 divided by 36 and you get 2 yards)
i dont know if im right......
2. x = 9
3. x = -7
4. x = 3.42 or 3.41
Let x be the unknown number. This means that "six times a number" becomes 6x. Finally, we want to compute the quotient between this quantity and 16, which leads to
