Answer:
Altura = 20,000 cm
Step-by-step explanation:
V = (pi x r^2 x a)/3
1.696.464 = (3.14 x 9^2 x a) / 3
1.696.464 = 84,82 altura
1.696.464 / 84,82 = altura
a = 20,000cm
Answer:
"Members of a population are organized in clusters, each of which is representative of the population, and then whole clusters are randomly selected to make up the sample"
Step-by-step explanation:
In cluster random sampling, "the population is divided, usually geographically, into groups that generally have the same size. A certain number of groups are randomly chosen, and every individual in the chosen groups are chosen for the sample."
In accord with this logic, the second choice, "Members of a population are organized in clusters, each of which is representative of the population, and then whole clusters are randomly selected to make up the sample" seems to be correct.
NOTE: This may not be the correct answer. I am simply basing my answer on the definition I have learnt.
Answer: The measures of center would most likely get smaller.
I assume that we are looking for the average rainfall during a month. If we had 7 days, there would be more rain meaning higher measures of center.
On the other hand, with only 3 days, they would most likely be lower. Unless, we had a lot of rain on those 3 days.
To find the tax you first move the decimal place 2 places to the left giving you the exact percent in decimal form. .075 is the correct decimal for this percent. You then multiply that percent by the cost of the product. (125) After multiplying you get the product $9.375. Then you round to the nearest tens place giving you $9.38
Answer:
w=10.75 l=32.25
Step-by-step explanation:
So if we know that the length is 3 times as long as the width than if the width is x, length would be 3x.
3x+3x+x+x=86 There are two lengths and two widths
8x=86 Combine like terms
x=10.75 divide both sides by 8 and our width is 10.75
Length is 32.25 multiply 10.75 by 3
