Step-by-step explanation:
just copy and paste these, then it'll give u theanswer on a number line on a graph and in standard form
(14,-1) is the answer to the question
I is a graph equation
It is asking you which of those options will make a line that would cross the two points that are listed in the question
So I am pretty sure the answer is option B
If this answer is not understandable please message me or leave a comment
Take DEBC a parralelogram
Parralel sides are DE and BC
THEREFORE,
1/2*(a+b)*h
1/2*(6+15)*h
1/2*(21)*h=0
10.5*h=0
h=-10.5
Answer to first part 1: First you obtain number of intervals you would like to have by getting the square root of the total number of observations. In this case, square root of 14 = 3.74; round up and use 4.0.
Answer to Second part: 2: The interval width is then obtained by dividing the range by the number of intervals. For this case, interval width = (42-9)/4 = 8.25. This can be rounded up to the convenient evenfigure of 10.0.
Hope this helps!!!!
