To answer the problem just add the frequencies that correspond to email counts that are 19 or fewer. So you're adding the counts that correspond to 0-9 and 10-19. So the frequency of 0-9 is 4 and the frequency of 10 -19 is 7. So 4 + 7 = 11

Which of the following arguments correctly justifies the second step of the flow proof of the triangle angle sum theorem below
pochemuha
We need to see the second step of the proof, so we know what needs to be justified. It would also be nice to see the list of answer choices. I'll never understand how someone who can't answer the question and has to ask someone else can then go ahead and decide that the person helping him only needs to see parts of the question.

Anthony has 15 coins, all of which are quarters and dimes. In all, they're worth $3.60. How many of each kind of coin does Antho
Usimov [2.4K]

Answer:

1 Dime

14 Quarters

Step-by-step explanation:

d + q = 15

0.10d + 0.25q = 3.60

d = 15 - q

0.10d + 0.25q = 3.60

0.10(15 - q) + 0.25q = 3.60

1.5 - 0.10q + 0.25q = 3.60

0.15q = 3.60 - 1.5

0.15q = 2.1

0.15q/0.15 = 2.1/0.15

q = 14

d = 15 - q

d = 15 - 14

d = 1
