The upper quartile is, Q1, is 45. The lower quartile, Q2, is 85. The interquartile range is 40. I hope this helps!
O.K.
(h; k) are the coordinates of the vertex.
On the graph are (3; 4), therefore we have:

We have the x-intercept (1; 0) → x = 1; y = 0.
Substitute them in the equation:

so. We have the answer:
Answer:
A) 8.25c + 25s = 206.25
B)This contribution affects the equation because it adds money and a person and because she is adding more than the normal amount that each student pays
Step-by-step explanation:
132/16= 8.25
each student paid $8.25
Would assume:
f(n + 1) = f(n) - 2
f(2) = f(1 + 1) = f(1) - 2 = 18 - 2 = 16
<span>f(3) = f(2 + 1) = f(2) - 2 = 16 - 2 = 14
</span>
<span>f(4) = f(3 + 1) = f(3) - 2 = 14 - 2 = 12
</span>
<span>f(5) = f(4 + 1) = f(4) - 2 = 12 - 2 = 10
</span>
f(5) = 10
Answer:
Yea it does
