The IQR is the difference between Q3 and Q1.
First we need to get the data from the stem and leaf plot:
10, 23, 23, 28,] [33, 45, 80, 90
Since there are 8 data items Q1 would be the median of the lower half (4 items), both are 23 so Q1 is 23.
Q3 is the median of the upper half, since the middle numbers are not the same we need to average 45 and 80. (45 + 80)/2 = 62.5 so Q3 = 62.5
IQR = 62.5 - 23 = 39.5
Well you will divide 27 by 12 because there are 12 months in a year to get 2.25 lbs per month, you go gurl, way to work out and loose weight:):) gope I helped
Answer: 6
Step-by-step explanation:
Let's start by getting the equation to slope intercept form
First simplify

Then get y by itself

In slope intercept form y=mx+b, m is the slope
In this case the slope is 6
Answer: {-16,4,92}. 2) {-16,10 ,42}. 3) {0,10,42}. 4) {0,4,92}. 5 The function f(x) = 2x. 2 + 6x - 12 has a domain.
Step-by-step explanation:
dividing 11.5 by 5 gives you the unit rate, then you just multiply that answer by 2 and you should be okay
