1/5 divided by 5/7 is 7/25
1/5 ÷ 7/5 = 7/25
Your answer is 7/25
Theoretical probablity=desiredoutcomes/totalpossibleoutcomes
desired=number of white marbles=20
total possible=red+blue+white=30+50+20=100
so theoretical probablity=20/100=2/10=0.2=20%

Answer:
principal (p)=$1895
time (t)=4years
rate(r)=7.9%
Step-by-step explanation:
- compound interest amount=p((1+r/100)^t-1)=$1895((1+7.9/100)^4-1)=$1895×((1.355)-1)=$1895×(0.355)=$672.725
- simple interest=ptr/100=$1895×4×7.9/100=$598.82
