Answer:
P(80-90)=66.666666...% Or 0.666666...
Step-by-step explanation:
Total tests = 21

14 ÷ 21 = 2/3 which is 66.66666% or 0.66666
Answer:
c =1/2
Step-by-step explanation:
2(3–5c) = 4(1–c) -1
Distribute
6 - 10c = 4 -4c -1
Combine like terms
6 - 10c =3 -4c
Add 10c to each side
6-10c+10c = 3 -4c+10c
6 = 3+6c
Subtract 3 from each side
6-3 = 3-3+6c
3 = 6c
Divide by 6
3/6 =6c/6
1/2 =c
