Answer:
24
Step-by-step explanation:
Just subtract the first quartile form the third quartile.
third quartile - first quartile
32 - 8 = 24 IQR
FIRST quartile: 8
SECOND quartile: 20
THIRD quartile: 32
So the IQR is 24

Find the perimeter of the rectangle with points...
W(6,9), X(9,7), Y(3,-2), Z(0,0)
Y - 5 = -1/2(x-1)
hope this helps!
Answer:
x=2
Step-by-step explanation:
log_x(y)+log_x(z)=log_x(yz), so logb(x-1) + logb(x+2)=logb((x-1)(x+2)). next subtract logb(8-2x) from both sides to get logb((x-1)(x+2))-logb(8-2x)=0. log_x(y) - log_x(z) = log_x(y/z). so now we have logb((x-1)(x+2)/(8-2x)). now you can put it into exponential form: (x-1)(x+2)/(8-2x)=b^0=1 now just solve for x:
(x-1)(x+2)= 8-2x, x^2 + x -2 = 8-2x, x^2 + 3x -10 = 0, (x+5)(x-2)=0 x=-5, x=2. plug both into the original equation to check which one is correct, since log_x(y) can't have a negative y, x=-5 doesnt work
C = 0.25r
this is becasue quarters have a value of 0.25 and c is the total cents
hope this helps and have a great day! :)
