Answer: 65 people completed graduate school.
Step-by-step explanation:
25% of 260 is 65.
Yes she does have enough. Here is why:
If you add 1/4 and 1/4, you get 2/8 which is also 1/2.
3/4 is bigger than one half. If you subtract 1/2 from 3/4, you get 1/4.
So she would have 1/4 left.
Absolutely enough to get to her friends house and back. :)
(- 3/4) + (-3/8)
= (- 6/8) - 3/8
= negative 9/8
Probably the most effective method researchers use to prevent sampling bias is through simple random sampling where samples are selected strictly by chance.
