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
Number of people =10
Total cost =145
now, we can find constant proportionality
k= ( total cost)/(number of people)
Let's assume
cost is C
number of people as x
so, we can set equation as
now, we can plug value
we can plug x=8
C=116
So,
we can draw graph
1) HL=LJ=63
(ZJ)²=16²+63²
(ZJ)²=256+3969
ZJ=√4425
ZJ= 65
2)HJ=HL+LJ
= 63+63
HJ=126
3) XC=XA=8
4) BE=AB/2=20/2=10

Answer: -2.5
The average can be found by adding up the numbers then dividing by how many numbers there are in this case there are two numbers.
-30+25=-5
-5/2 = -2.5
