62.831 because the firs number that is different between the two is .8 and .3, and .8 is greater regardless of the numbers that follow afterward.
Answer:
x^2 + 6
Step-by-step explanation:
X squared or "x^2" just means X times X. For example, 9^2=81 which is the same as 9x9. Then just add 6.
Hope this helps
The sum of (2x-5y) and (x+y)
(2x-5y)+(x+y) combine like terms
3x-4y

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.

Answer:
2198 cm²
Step-by-step explanation:
Total surface area of a cylinder = 2πrh + 2πr²
Radius, r = diameter/2
= 20cm/2
= 10 cm
Height, h = 25 cm
Total surface area of a cylinder = 2πrh + 2πr²
= 2*3.14*10*25 + 2*3.14*10²
= 1,570 + 6.28*100
= 1,570 + 628
= 2198 cm²
Total surface area of a cylinder = 2,198 cm²
