A, b, and c are used as variables.. letters in the place of the where a number would originally be. So in that statement, a is less then b while b is less then c making c the largest number, the one greater upon the three.
Answer:
To select a <u>stratified</u> random sample, first classify the population into groups of similar individuals, then choose a separate SRS in each group and combine these SRS to form the full sample
Step-by-step explanation:
Stratified random sampling involved dividing the population into small groups of similar individuals (called strata) and then from among those groups, a stratified random sample is selected and then, all these samples are combined to form the full sample. Hence, the missing word in this sentence is <u>stratified.</u>
Answer:
well there is 60% girls
Step-by-step explanation:
40% are boys out of 100%
So what you have to do is find out what added by 40 is 100 which is 60 so it's
40% boys to 60% girls
Answer:
Step-by-step explanation:
you could think that 22% is close to 25% , so one forth of it, 1/4
78 percent is close to 80
1/4 of 80 is 20
actually 78*22/100=17.16
Given:
x and y are both differentiable functions of t.
To find:
The value of 
.
Solution:
We have,
...(i)
At x=-1,
Divide both sides by 3.
Taking cube root on both sides.
So, y=2 at x=-1.
Differentiate (i) with respect to t.
Putting x=-1, y=2 and 
, we get
Divide both sides by -8.
Therefore, the value of is 36.
