Answer: c. Stratified sampling
Step-by-step explanation:
Stratified sampling is a sampling method in which the studied population is divided into separate groups or subgroups known as strata, there after a simple random sample can then be drawn from each separate or subgroups.
One of the main merit of stratified sampling is that it helps to reduce the size of sample required to get accurate result.
Let number be x and x+13
Then x+x+13=15 (A/q)
2x+13=15
2x=2
X=1
:. X+13= 14
Two numbers are 1 And 14
The correct answer is 10/15
6/9 simplified is 2/3.
2/3 multiplied by the scale factor of 5 is 10/15.
2/3=6/9=10/15

Answer:26 retart
Step-by-step explanation:
Hello!
You will solve this like an algebraic equation.
54 - y = 174
Subtract 54 from both sides
- y = 120
Since y is negative you can multiply both sides by -1 to make y positive
y = -120
Hope this helps!
