Answer:
Step-by-step explanation:
Given
See attachment for box plot
Required
The interquartile range (IQR)
This is calculated using:
On the second attachment, I identify the positions of Q1 and Q3 respectively;
So:
<em>The interquartile range is 38</em>
Your first step would be to unsolve the zeros, which would leave you with x-1, x-1, and x+2. Then arrange the zeros in the position of a factored polynomial, such as (x-1)(x-1)(x+2), and then FOIL the first two terms. You would then end up with, x^2-2x+1(x+2). After this just finish unfactoring the polynomial.
Your answer would be:
1x^3+0x^2+-3x+2
Answer:
-40
Step-by-step explanation:
Multiply both sides by the reciprocal of 9/10 to get rid of the fraction
