Answer:
stratisfied Sampling
Step-by-step explanation:
By definition, stratified sampling is a method of sampling from a population which can be partitioned into subpopulations.
In this modern space age in which we live, we'll need to be careful.
2 kilograms weighs 4.409 pounds on Earth. If that much
costs $3.20, then the cost for 4 pounds is
(4 / 4.09) x (3.20) = $2.90 .
But what if you grow up to live or work on the Moon ?
2 kilograms weighs only 0.73 pounds on the Moon. If that much
costs $3.20, then the cost for 4 pounds up there is
(4 / 0.73) x (3.20) = $17.54 .
The thing to remember is that if you make frequent trips between
the Earth and the Moon, make sure you buy stuff by mass, not by
weight. The weight changes when you take it somewhere else,
and you don't want to get cheated.
To find height divide the area of a cylinder by its base. since the base is a circle and area for a circle is A = (3.14) x r^2 fill it in and you get the base with an area of 12.56.
divide 100 by 12.56 = 7.96
Answer:
Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.
