Answer:
The answer is
<h2>

</h2>
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
<h3>

</h3>
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-7, 1), and (-4, -3)
The slope is
<h3>

</h3>
We have the final answer as
<h3>

</h3>

Answer:5
Step-by-step explanation:
Answer:
108.5
Step-by-step explanation:
46.50/3= 15.50
15.50 x 7=106.5
D1,..,d9 = 0,0,2,2,2,3,4,6,8 //there are 9 values, in ascending order
Q2 (median) = d5 = 2 //value in the middle
Q1 = (d2+d3) / 2 = (0+2)/2 = 1
(Q1 is middle value of d1,d2,d3,d4, but there is no middle element among four elements, that is why arithmetic mean is taken)
Q3 = (d7+d8) / 2 = (4+6)/2 = 5
interquantlie range = IQR = Q3 - Q1 = 5 -1 = 4
answer: 4
