Answer:

The Mean is 3

Step-by-step explanation:

For future reference, here's how to solve the mean.

<em><u>1.Add up all data values to get the sum</u></em>

<em><u>2.Count the number of values in your data set  and divide the sum by that number.</u></em>

In this problem, there are 5 values, and all the values added together equals 15. Divide 15 by 5 and you get 3. The mean is 3.

Identify any extraneous solution. See above pic
Sav [38]

Answer:

There are no extraneous solutions

Reasoning:

An extraneous solution is a solution that isn't valid, it might be imaginary like the square root of a negative number.

first we want to isolate z:

1+sqrt(z)=sqrt(z+5)

^2 all      ^2 all

(1+sqrt(z))(1+sqrt(z))=z+5

expand

1+2sqrt(z)+z=z+5

-1              -z  -z -1

2sqrt(z)=4

/2           /2

sqrt(z)=2

^2 all    ^2 all

z=4

Since there is one solution and it is a real number, there are no extraneous solutions.
