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

If LN = 12x + 16, what is the length of Line segment L N in units?
elena55 [62]

Answer:

LN = 64 units

Step-by-step explanation:

Given M lies on LN, so LN = LM + MN --------------(1)

LN = 12x + 16

LM = 10x + 8

MN = 5x - 4

Substituting the values in equation 1, we get:

12x + 16 = (10x + 8) + (5x - 4)

12x + 16 = 15x + 4

15x - 12x = 16 -4

3x=12

Therefore x=4

LN= 12(4) + 16 = 64 units

The circumference of one of the smaller circles is 12pie cm. Find the circumference of the larger circle.. . A. 12pie cm. B. 24p
Temka [501]
There exists a similar question that would lead to the relationship of the given circumference to the unknown value. The radius of the larger circle is 12 cm. The formula for determining the circumference is,
                                  C = 2πr
Substituting the known value,
                                    C = 2π x 12 cm = 24π cm
Thus, the answer is letter B.
