Answer:
D. 36, 12
Step-by-step explanation:
Okay, so for the first part (how many total students are in Ms. Smith's class) all we need to do is count all the dots. So there's 5 in the none category, 6 in the one category, 1 in the two category, 6 in the three category, 8 in the four category, 5 in the five category, 2 in the six, 2 in the seven, and 1 in the nine, so we add all that up:
5 + 6 + 1 + 6 + 8 + 5 + 2 + 2 + 1 = 36
So there's 36 students total in Ms. Smith's class
Now we have to count how many students have less than 3 siblings, so we're going through the 0 - 2 categories:
5 + 6 + 1 = 12
So there's 12 students in Ms. Smith's class with less than 3 siblings
let me know if this is wrong
hope this helps:)
6n - 13 = 27
6n = 27 + 13
6n = 40
n = 40/6
n = 6 2/3
Answer: n = 6 2/3
