1744.5 hours, you multiply 72 times 24 (72 days, 24 hours in a day) and add the 300 minutes (.5)

So, we have the amount of time for Planet Hulu for 1 day, but we need to convert into hours. Each day is 24 hours and it takes planet hulu 72 days to do 1 rotation. Time for the math!

Multiplication: 72*24=1728

Now, we have our time of 1728 hours and 30 minutes. But wait! 30 minutes is half of an hour, so we can add a .5 to the end of our number and get our final answer:

Answer: 1728.5 hours for one full day to go by on Planet Hulu.

avanturin [10]

Answer:

0.0286 = 2.86% probability that today is Monday.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Dressed correctly

Event B: Monday

Probability of being dressed correctly:

100% = 1 out of 4/7(mom dresses).

(0.5)^3 = 0.125 out of 3/7(toddler dresses himself). So

P(A) = 0.125\frac{3}{7} + \frac{4}{7} = \frac{0.125*3 + 4}{7} = \frac{4.375}{7} = 0.625

Probability of being dressed correctly and being Monday:

The toddler dresses himself on Monday, so (0.5)^3 = 0.125 probability of him being dressed correctly, 1/7 probability of being Monday, so:

P(A \cap B) = 0.125\frac{1}{7} = 0.0179

What is the probability that today is Monday?

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0179}{0.625} = 0.0286

0.0286 = 2.86% probability that today is Monday.

QUESTION 1
RoseWind [281]

Answer:

1) (D)

2) (B)

3) (C)

Step-by-step explanation:

1) Amount borrowed = $1380 (P)

APR =13% or 0.13 (R)

Time = 15 months (T) = 15/12

Interest amount = \frac{P*R*T}{100}

                           =  \frac{1380*13*15}{1200}

                          = $224.25

Total amount  = 1380+224.25

                        = $1604.25

Monthly payment = 1604.25/15 = $106.95 (D)

2) Amount borrowed = $2240

APR = 15% or 0.15

Time = 18 months

Interest = \frac{P*R*T}{100}

           = \frac{2240*15*18}{1200}

          = $504 (B)

3) Amount borrowed = $5500

APR = 11.5% or 0.115

Time = 5 years

n= 12 (compounded monthly)

M = \frac{P}{\frac{1-(1+r/n)^{-nt}}{r/n} }

   = \frac{5500}{\frac{1-(1+\frac{0.115}{12} )^{-60}}{\frac{0.115}{12}} }

  = $120.95 (C)
