Answer:

The length of AB is 30 units.

Step-by-step explanation:

Given B is the midpoint of AC and D is the midpoint of CE.

BD = 3x, AE = 60 and  AC = 5x + 10

we have to find the value of AB.

As B is the mid point of AC and D is the mid-point of CE.

By mid-point formula, the length of line joining the mid-points of two sides of triangle is half of the parallel side.

∴ BD=\frac{1}{2}AE

⇒ 3x=\frac{1}{2}\times 60

⇒ x=10units

As, B is the mid-point of AC

⇒ AB=\frac{1}{2}AC=\frac{1}{2}(5x+10)=\frac{1}{2}(5(10)+10)=30units

The length of AB is 30 units.

Answer:

Cluster sample

Step-by-step explanation:

This is an example of a cluster sample. In a cluster sample, the examiner divides the population into groups (each one of these groups is called a cluster) and once the examiner has these clusters, takes one of them and recollects the data from ALL the members of that cluster. In this case, the teacher divided the class in 3 different groups and then selects one of these groups and asks the average amount of time per week he/she spent studying.
