The answer is A because 25 percent is equivalent to .25
Answer:
2 because if x=0 y=1 and 2 is closest so a and b
28 ÷ 2 = 14. you need 14 cups of each nut to get a total of 28 cups combined
The probability that his number will be 4 is one in eleven, or 1/11.
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
