Step-by-step explanation:
Equ of line -
y=mx+c
Using point (3,-1)
3 as x, - 1 as y
M=2/3
Substitute the values of these coordinates
3=2/3(-1) +c - - - - now find for c
c= 3- (-2/3)
c= 3.67
Now with the value of c, put the values back into the equation form .. Assuming we don't have a point to work with
y=2/3x + 3.67
A is not true, there are only 1 in the 70 inches tall column, and 3 in 69 1/2 column.
B is right, there are more dots in the right side of the data set.
C is not true, there is one dots in the 68 1/2, which means there is one player that is 68 1/2 inches.
D is right, because there are four dots in the column of 71
E is right, because there are total 6 different list/ column of dots.
F I am not sure, I think it is not true, because 74 inches is more like a outlier than 68 1/2
Right answer: B D E
Answer:
13a: Measure of angle 1 is 120 degrees
13b: Angle 2 is 60 degrees
Step-by-step explanation:
Angle 1 is alternate exterior (so in a parallel pair they are equal) to the angle on line m given as 120 deg.
Angle 2 is 180 minus 120= 60 Sum of the two angles must equal 180.
Answer: C. 5/6
Steps:
Use the formula x1-x2/y1-y2 to find the slope
(5,11), (-5,-1)
-5-5/-1-11
= -10/-12
=5/6
