Arrange in ascending order:-
6 7 11 13 14 15 15 19 21
median = 14
lower quartile = mean of 7 and 11 = 9
upper quatile = mean of 15 and 19 = 17
Interquartile range = 17 - 9 = 8
answer is 8
Just use the power rule:
We also could have use the fact that the integrand is even to write
I'll continue with this expression since it's easier to evaluate (if only a little):
Answer:
Step-by-step explanation:
The equation of a line is given by
Y=mx+c
m= the slope (2/3)
Therefore applying slope and one point method, the equation is given by
y-y1= m(x-x1)
y-3=2/3(x+5)
= y-3= 2x/3 + 10/3
3(y-3)=2x+10
3y-9=2x+10
3y=2x+19
$57.52
divide the price for 6 people by 6, then multiply it by 9.
56 because
2(1)=2
3(2)=6
4(3)=12
5(4)=20
6(5)=30
7(6)=42
8(7)=56
