Answer, will mark brainliest ^^ (worth 61 points)

1) ven diagram #1

2)160

3) 420

4)16

Step-by-step explanation:

1) lets make a ratio table:

(look at image below, sorry for the horrible writing)

the original ratios are 18 and 17, and 18+17=35   35 is the number of students who play either or both sports. 30 is the number who play either sport:

so 35-30=5

5 students play both sports:

18-5=13(baseball)

17-5=12(basketball)

2) add up all the students who do band or sports and subtract from the total number of students

so

89/464+215/464= 304/464 students play in band or orchestra or both, to find the number of students who dont:

464-304=160

3) 630/1000+420/1000=1050/1000

1050/1000-210/1000=840/1000

840/1000-420/100=420/1000

420 ppl use brand p

4) 15+9=24

40-24=16

16 ppl

hope this helps!

1) option 1

2) 191 students

3) 420 people

4) 16

Step-by-step explanation:

n(Baseball & Basketball) = x

30 = 18 + 17 - x

30 = 35 - x

x = 35 - 30

x = 5

Only basketball: 17 - 5 = 12

Only baseball: 18 - 5 = 13

2) 464 - (89 + 215 - 31)

464 - 273

192

3) 630 - 210 = 420

4) 40 - 15 - 9 = 16
