<u>Given</u>:
Given that the radius of the circle is √98 units.
The circle is centered at the point (5.9, 6.7)
We need to determine the equation of the circle.
<u>Equation of the circle:</u>
The general form of the equation of the circle is given by

where (h,k) is the center and r is the radius of the circle.
Substituting the center point (h,k) = (5.9, 6.7) and r = √98, we get;

Simplifying, we get;

Thus, the equation of the circle is 
Answer: b) sq. root of 65
use pythagorean theorem to solve
a2+b2=c2
3^2+b^2=5^2
9+b^2=25
b^2=16
b=4
apply to other triangle for second leg
7^2+4^2=c^2
49+16=c^2
65=c^2
sq root of 65= c
Answer:
Snowball Sampling
Step-by-step explanation:
Based on the specific scenario that is being described it can be said that the best type of sampling for you to use would be Snowball Sampling. This is a unique nonprobability sampling technique where subjects for the experiment at hand are recruited from the existing subjects list of acquaintances. Such as in this case it would target all the acquaintances of the Sting-Ray owners.
Answer:
9, 12, -5
Step-by-step explanation:
Let us move all the terms to one side.
9x^2+12x-5=0
Therefore, using the quad formula of ax^2+by+c=0,
a=9
b=12
c=-5
Hope this helps! :)
Answer:
Sampling Error
Step-by-step explanation:
When the researcher randomly selected 200 people, he is creating an sample or subset from the population, that would be all the people in the earth. The error obtained was product of the fact that the analysis he made was estimated from the sample and not the whole population. There is no other mentioned factor that could cause an error, so the answer would be a sampling Error.
