Answer:
It's 45 is it not? The coordinate is (1,45) I could be wrong. I believe it is D.
(Sorry if I am wrong!)
Step-by-step explanation:
when the value of one variable is related to the value of a second variable we have a relation
The stem and leaf plot will look like:
6 | 1 5 8 - 3 scores
7 | 1 7 7 9 - 4 scores
8 | 2 3 4 5 7 9 - 6 scores
9 | 0 1 4 7 9 - 1 score
To total up the number of students who scored less than 90, we have 3 under 60-69, 4 under 70-79, and 6 under 80-89, so this is 3 + 4 + 6. This is the third choice.
Answer:
2x - y - 4 = 0
Step-by-step explanation:
Here, (x1,y1) = (0,4) and m = -2
Point-slope form of the equation of a line is
y - y1 = m(x - x1)
So,
y - 4 = -2(x - 0)
y - 4 = -2x
2x - y - 4 = 0 is the equation of the line.
