Answer: 1.5923926292577
Step-by-step explanation: Count, N: 14
Sum, Σx: 49
Mean, μ: 3.5
Variance, σ2: 2.5357142857143
Steps
σ2 =
Σ(xi - μ)2
N
=
(1 - 3.5)2 + ... + (6 - 3.5)2
14
=
35.5
14
= 2.5357142857143
σ = √2.5357142857143
= 1.5923926292577
<u>Answer:</u>
The slope is 0.8 or 4/5.
<u>Step-by-step explanation:</u>
Let's take two points on a line. (-2,0) and (3,4).
Now, determine the rise and run.
Slope = Rise/Run
<u>Conclusion: </u>
Therefore, the slope is 0.8 or 4/5.

Answer:
Step-by-step explanation:
The last (fourth) graph is that of the parent function y = √x. The negative sign in front of √x leads to reflection of this parent function graph in the x-axis. Thus, the correct graph of f(x) = -√x is the first one.
