Answer:
Step-by-step explanation:
Любимая радиостанция Линды, WMAT, раздает один бесплатный пропуск на концерт за кулисами каждые 60 минут в течение одного дня. Его дочерняя станция, KPRO, раздает один бесплатный билет на общий концерт каждые 65 минут в один и тот же день. Чтобы выиграть любой из билетов, Линда должна быть первой, кто позвонит на станцию после объявления. Правила запрещают ей выигрывать оба билета.
This problem is easier solved by finding the probability that she does NOT do her homework both Monday and Tuesday, which is obtained by the multiplication rule.
P(no HW on Monday) = 1-0.75 = 0.25
P(no HW on Tuesday) = 1-0.75 = 0.25
P(no HW on both Monday and Tuesday) = 0.25*0.25=0.0625
[by the multiplication rule]
This means that the rest of the time (1-0.0625=0.9375) Elsie does her homework either Monday, or Tuesday, or both days.
=>
P(HW either Monday, Tuesday, or both) = 0.9375
(note: in current English, Monday or Tuesday means "either Monday, Tuesday, or both days")
Answer:
A = 1000 ( 1 + .031/12) ^(12t)
The approximate monthly interest rate is .2583 percent
Step-by-step explanation:
A=1000(1.031)^t
The formula for compound interest is given by
A = P(1 + r/n) ^ (nt)
Take 1.031 and subtract 1
.031 is the yearly rate in decimal form
A = 1000 ( 1 + .031/12) ^(12t)
Change to a percent = 3.1 %
Divide by 12
3.1/12 = .2583333333(repeating) %
This would be the monthly rate
Answer:
x<-3 or x>2, 2<x<-3
Step-by-step explanation:
Subtract/add from each side then divide, if dividing by a negative reverse the sign.
Answer:
-4
