Question 1 is no doubt B, because Johnny only asked the students in his science class, not the entire school's population. As for question 2, If you could give me a picture of the actual graph, that would be fantastic. Until then, i don't think I can answer Q2 properly.

Question 1 is D.<em> </em>

It's not clear that the science class is a good sample of the school as a whole. It may be an elective or for a particular grade, making it a biased sample.

For Question 2 I'll try to create the histogram from your description.

N TOP BOTTOM

9 3 3

10 5 4

11 2 3

If that's accurate the BOTTOM, B, group has longer arms, due to a single person measuring 11 instead of 10.

Neither B or D is really a good answer making me think I transcribed the table incorrectly. I'd guess D

Write an equation of the line that passes through the point(-6,-9) with slope -5
LUCKY_DIMON [66]

Answer:

  y = -5(x +6) -9

Step-by-step explanation:

The point-slope form of the equation for a line can be written as ...

  y = m(x -h) +k

for a line with slope m through point (h, k).

You have m=-5 and (h, k) = (-6, -9). Filling in these values gives ...

  y = -5(x -(-6)) -9

Simplifying a bit, you get ...

  y = -5(x +6) -9
