Answer:
-3
Step-by-step explanation:

The standard deviation is 1.43 below the mean
<h3>How to determine the number of standard deviation?</h3>
The given parameters are:
Mean = 98.249
Standard deviation = 0.733
x = 97.2
To calculate the number of standard deviation below the mean, we use

So, we have:

Evaluate the like terms

Divide both sides by -0.733
n =1.43
Hence, the standard deviation is 1.43 below the mean

This is a vertical parabola, because (x-1)².
Vertex of the parabola (1,1).
So line symmetry is x=1.
The Area of Sector = 49.0873852187 thus 49.06 cm² the answer is C.
Answer:
y=17/3x+2
Step-by-step explanation:
Get 2 points from the graph
(3;19) (-10;2)
Grad=change in y/change in x
=2-19/-10-3
=-17/-13
=17/3
y=mx+c
19=17/13(3)+c
19=17+c
19-17=c
2=c
y=17/13x+2.
Well I think you are supposed to find the equation of the line so I think that's it.
