Answer:
-2a-4n+14
Step-by-step explanation:
I assume that in this question, you are asked to evaluate the value(s) of r. To answer that question, dividing 1252 by 48 gives us 26.0833 or 26. Mathematically expressing the solution,
26 = 26r^4
Then, divide the equation by 26, giving us 1 = r^4. Evaluate r. This will give us answers of +-1.

..............Answer
Answer: 0.4987
Step-by-step explanation:
Given : The weights of newborn baby boys born at a local hospital are believed to have a normal distribution with
Mean : 
Standard deviation : 
Let X be the random variable that represents the weight of randomly selected student .
Z score : 
For x = 5 lbs

For x = 11 lbs

By using the standard normal distribution table , the probability that the weight of the newborn baby boy will be between 5 lbs and 11 lbs :-

Hence, the probability that the weight of the newborn baby boy will be between 5 lbs and 11 lbs =0.4987
