Answer:
1 / 8 ÷ 3 = 1 / 24
3 ÷ 1 / 8 = 24
Step-by-step explanation:
1 / 8 ÷ 3
= ( 1 / 8 ) / 3
= 1 / ( 8 x 3 )
= 1 / 24
3 ÷ 1 / 8
= 3 / ( 1 / 8 )
= ( 3 x 8 ) / 1
= 24
Answer:
False
Step-by-step explanation:
This is false because a population represents all and not some. A population is the collection of all outcomes, responses, measurements, or counts that are of interest. It is not a collection of 'some' outcomes. It is a collection of 'all' outcomes.

Answer:
(a)
(b)
(c)
the cost of 8 people is $116
(d)
Graph is attached
Step-by-step explanation:
we are given
It costs $145 for 10 people to attend a concert
(a)
Number of people =10
Total cost =145
now, we can find constant proportionality
k= ( total cost)/(number of people)
(b)
Let's assume
cost is C
number of people as x
so, we can set equation as
now, we can plug value
(c)
we can plug x=8
C=116
So,
the cost of 8 people is $116
(d)
we can draw graph
