Debora [2.8K]3 years ago
8 0

Answer:

A, B, D

Step-by-step explanation:

A random sample is one in which every member of the population has an equal chance of being chosen.

If employees are chosen out of a hat, or balls are drawn from a bowl, each has an equal chance of being chosen.

Samples selected through volunteering, or where not everyone has an equal chance of being selected, is not random.

What is the sum of 1 2/8 + 2 5/8
SVEN [57.7K]
Hey there!

1 + 2 = 3

2/8 + 5/8 . . .

= 7/8 (denominator stays the same)

3 + 7/8 = 3 7/8

The sum of the numbers 1 2/8 and 2 5/8 is 3 7/8.

1 2/8 + 2 5/8 = 3 7/8.

Hope this helps you.
Have a great day!
