Answer:
The answer is C
Step-by-step explanation:
First of all let's eliminate the answers that do not make sense. For A. numbers are NOT irrational because they are a fraction. Numbers are also not irrational because they are a repeating number. C and D are both correct as fractions and terminating decimals are both rational numbers.
34/3≈11.33333333
By using a certain formula you can convert repeating decimals to a fraction. But most people know that .3333333 is 1/3. This gives us 11 1/3 as our answer. So what does it match? It is not a terminating decimal. It repeats but can be written as a fraction. Therefore our answer is C) Rational, because it is a fraction.
Answer:
Step-by-step explanation:
Surface Area of Cuboid= 2(6x3)+2(6x10)+2(3x10)=216m²
Surface Area of Sphere= 4πr²
= 4xπx6²
= 144πm²
Surface Area= 144π+216
Answer:
c. 10
Step-by-step explanation:
Pick any two points from the table. I chose (0, -20) and (1, -10)
Let's find the slope between your two points.
(0,−20) (1,−10)
(x1, y1)=(0, −20)
(x2, y2)=(1, −10)
Use the slope formula:
m= y2 − y1 / x2 − x1
= −10 − −20 / 1 − 0
= 10 / 1
= 10
Answer:
c. Cluster sampling
Step-by-step explanation:
Taking into account that the exercise researcher is looking with limited resources to study a population that is divided, her best option is cluster sampling, which is a method applicable to this type of population, we could select in each group randomly her sample, the observational study is discarded because she does not have much availability of time or resources, nor would the stratified study be useful because she should select subgroups and create them to take samples and this would take more time and resources and sampling systematic is not adequate because it must have all the individuals and after having the list select the sample, but as we know, it is a process that will study the number of individuals so this option is not feasible.
