Answer:
The greatest common factor of 12m^2 and 9b^4 is 3.
I hope this could help, let me know if you need anymore help.
1. You have that the circle that defines the part of the planter wall which gets watered by the sprinkler is: (x−10)²+(y+12)²<span>=36.
2. The standard form for the equation of a circle is:
(x-h)</span>²+(y-k)²=r²
(h,k) is the center point.
r is the radius.
3. Keeping this on mind, you can find the value of the radius, as below:
r²=36
r=√36
r=6 m
4. Then, the diameter of the circle is:
D=2r
D=2(6m)
D=12 m
<span>
What is the diameter, in meters, of the circular area that gets watered by the sprinkler?</span>
The answer is: 12 m
It is found that Margo will be using random sampling.
• Random sampling in statistics is a part of the sampling technique in which each sample has an equal probability of being chosen. In other words, a sample chosen randomly is an unbiased representation of the total population.
Sample strategies may be classified as :
1) Convenient : The sample which is drawn from a conveniently available pool.
2) Random : When all options are into a hat and draw some of team
3) Systematic : Every kth element
4) Cluster : When we divide population into groups called clusters, and each element os cluster is surveyed.
5) Stratified : In stratified also divides the population into groups, However only some of the elements of the group are surveyed.
According to the question
Marbles are taken from the bag, and after they are taken they are again placed back in the bag so it depicts Random Sampling.

X/5= 15
So we gotta get x alone sooo
Since it’s division we do reverse and do multiplication for the answer
So 15 times 5 is 75
X = 75
Size of the painting: A * B
Scale factor: 1/3
Size of the photo: [1/3]A * [1/3]B
[1/3]A = 13inches
A = 13inches * 3 = 39 inches
[1/3]B = 17 inches
B = 17 inces * 3 = 51 inches.
Answer: the size of the painting is 39 inches by 51 inches.
