Answer:
100 children
150 adults
Step-by-step explanation:
c- children
a- adults
---------------
we get equations as per question:
- 1.5c+4a= 750
- c+a= 250 ⇒ a= 250- c
- 1.5c +4(250-c)= 750 ⇒
- 1.5c- 4c+1000=750 ⇒
- 2.5 c= 250 ⇒
- c= 100
- a= 250-100 ⇒
- a= 150
Children 100, adults 150
Step-by-step explanation:
A negatively skewed distribution means that the distribution curve doesn't fall evenly on both sides of the median, but stretches out further to the low end. If the values above the median are only slightly above the median, but those below it could be far below it, the average (mean) will be below the median. If the mean (average) is 68, then the median must be above it, or 72.
