Cause its not :/ why would it be
If so then it is not rational Square root of 2 is irrational and any number formed by multiplying or dividing it by a rational number is also irrational.
The mean and standard deviation for the number of boys in the 950 babies are 475 and 15.41, respectively
<h3>How to determine the mean and the standard deviation?</h3>
From the complete question, we have:
P(boy)= 0.5
Sample size = 950
The mean is then calculated as:

This gives

Evaluate

The standard deviation is calculated as:

This gives

Evaluate

Hence, the mean and standard deviation for the number of boys in the 950 babies are 475 and 15.41, respectively

Answer:
NO 2+2 = 22
Step-by-step explanation:
As it's a square root the underroot value must be greater than or equal to 0
So
let's find out the domain
- √4x+11≥0
- 4x+11≥0
- 4x≥-11
- x≥-11/4
Domain
