Answer:
C
Step-by-step explanation:
Money lost. Keyword "lost". Ages, people, and height can't be negative. ( I guess people can be negative mentally but not physically)

Answer:
192
Step-by-step explanation:
to find the mean you have to use this formula: mean= N(total number of trials) times P( probability of "success")
n=640
p=0.3
640x0.3= 192
If 36 is 80% ( a piece) of a number. that means the number must be higher than 36
Changing the English to math:
36 = 80% x n (n being the number)
36= .8n (changed the percent to a decimal by moving it back two places
<u>36</u> = <u>.8</u>n
.8 .8 I divided both sides by .8 - when you divide a number by a decimal (less than one) the number will become larger.
The answer is 45
