Answer:
1. r=17
2. (-15,14) or (-15,-16)
Step-by-step explanation:
The radius of the circle is the distance from the center to the point on the circle, thus

The equation of the circle is

If point lies on this circle, then its coordinates satisfy the circle's equation:

Answer:h=e-200/3
Step-by-step explanation:
Answer:
a)
=4.63 md=4.55 mo= 1.9 b) Sample Standard Deviation≈ 2.58 Coefficient of Variation=55.72% Sample Range=6.9
Step-by-step explanation:
a)
<u>Mean</u>

For the <u>Median</u>, we have to order the entries. So, ordering it goes:
1.9 1.9 2.3 3.9 5.2 5.7 7.3 8.8
Since we have even entries 
mode
The mode for this data 1.9 1.9 2.3 3.9 5.2 5.7 7.3 8.8 is 1.9
b)
<u>Sample Standard Deviation</u>
Here it is the formula to calculate it:

<u>Coefficient of Variation</u>
CV is the quocient between sample Standard deviation over Mean and it is used to make comparisons.

<u>Range</u>
The difference between the highest and the lowest value of this sample
8.8-1.9=6.9
Answer:
either negative or positive integer
hope that helps uhh :)
Please double check my work
AB = -2x
BC = 4x
