Janie flips a coin 70 times and records if it comes up heads. If getting heads is a success, what is the probability of a failure? 0. 2 0. 5 0. 7 1. 0.

Answers

The probability of a failure is 0.5

Probability is the likelihood or chance that an event will occur.

Probability  = Expected outcome/Total outcome

Since Janie flips a coin 70 times, then the total outcome is 70

The probability of getting a failure will be 50% of the total times;

Expected outcome  = 50% of 70

Expected outcome = 35

Pr(a failure) = 35/70

Pr(a failure) = 0.5

Hence the probability of a failure is 0.5

Mindy owns 20 pairs of shoes and every week she purchases two more pairs. How long will it take for her closet to have 50 pairs of shoes?

Answers

Answer: she will get 50 shoes in 15 weeks

How: she gets 2 pairs of shoes each week and she need 30 more shoes. 30 divided by 2 equals 15.

The number of weeks that takes for her closet to have 50 pairs of shoes will be 15 weeks.

What is an arithmetic sequence?

Let a₁ be the first term and d be a common difference.

Then the nth term of the arithmetic sequence is given as,

aₙ = a₁ + (n - 1)d

Mindy claims 20 sets of shoes and consistently she buys two additional matches.

The first term is 20 and the common difference between the succession terms is 2. Then the equation is given as,

aₙ = a₁ + nd

aₙ = 20 + 2n

The number of weeks is given as,

50 = 20 + 2n

50 = 20 + 2n

50 = 20 + 2n

Simplify the equation, then we have

2n = 50 - 20

2n = 30

n = 30 / 2

n = 15

The number of weeks that takes for her closet to have 50 pairs of shoes will be 15 weeks.

Tammy’s home cost her $184,000. She lives in an area with a lively real estate market, and her home increases in value by 3. 5% every year. If Tammy sells her home after thirteen years, how much profit will she have made, to the nearest hundred dollars? a. $8,500 b. $87,800 c. $83,700 d. $103,800.

Answers

The profit to be made when she sells the house is $103,800.

The first step is to determine the value of Tammy's house in 13 years. The formula to be used is:

FV = P (1 + r)^n FV = Future value  P = Present value  R = interest rate   N = number of years  

$184,000 x (1.035)^13 = $287,767.92

Profit = value of the house in 13 years - cost of the house

$287,767.92 - $184,000 = 103,767 = $103,800
