Answer 1

Answer:

B. [tex]\frac{14}{625}[/tex]

Step-by-step explanation:

Total paper in the hat:

2 blue + 6 red + 10 yellow + 7 purple = 25 total pieces of paper

P(AB) = 7 / 25 x 2 / 25

A is the probability of pulling a purple paper

B is the probability of pulling a blue paper

Answer 2

Answer:

14/625

Step-by-step explanation:

probability = favorable outcomes/total number of outcomes

First find the probability of drawing a purple piece of paper.

There are 7 pieces of purple paper.

Add all the amounts of colored paper together to get the total number of outcomes.

2 + 6 + 10 + 7 = 25

The probability of drawing purple is 7/25

Now find the probability of drawing blue. There are 2 blue pieces of paper. Since he replaces the purple paper the total stays at 25.

The probability of drawing blue is 2/25

This is a compound probability problem, so multiply the two probabilities together.

7/25 x 2/25

14/625

Ingrid Nilsen purchased a $4,000 hydroponic system for her garden. The down payment is 20%, and the
installment loan has an APR of 10% for 36 months. Find the a) down payment, b) amount financed, c) monthly
payment, d) total amount repaid, and e) finance charge.

Answers

The purchase of the hydroponic system by Ingrid Nilsen for $4,000 with a 20% down payment at 10% APR for 36 months, and the related calculations, are as follows:

a) down payment = $800.00 ($4,000 x 20%)

b) amount financed = $3,200 ($4,000 - $800)

c) monthly payment = $103.25

d) total amount repaid = $4,517

e) finance charge = $517

How is periodic payment computed?

The amount of the periodic payment, finance charge, and total repayment can be computed using an online finance calculator as follows:

Data and Calculations:

Auto Price = $4,000

Loan Term = 36 months

Interest Rate = 10%

Down Payment = $800 ($4,000 x 20%)

Monthly Payment = $103.25

Total Loan Amount $3,200.00

Upfront Payment = $800.00 ($4,000 x 20%)

Total of 36 Loan Payments = $3,717. ($103.25 x 36)

Total Loan Interest = $517

Total Cost (price, interest, tax, fees) = $4,517

Thus, Ingrid Nilsen repaid a total of $4,517 with $517 in interest (finance charge).

b) 294.76
c) 525.51
d) 304

Answers

Answer:

A) 266.39

Step-by-step explanation:

Answer:

a) 266.39 unit^2.

Step-by-step explanation:

Area of the base = 8^2 = 64 .

There are 4 triangular sides.

To find the area of 1 side we need to know the slant height s of the triangle, This can be found using the Pythagoras Theorem

s^2 = 4^2 + 12^2 = 160

s = √160

So the area of 1 side = 1/2 * base * s

= 1/2 * 8 * √160

and

area of 4 sides

= 4 * 1/2 * 8 * √160

= 202.386

So the Surface area of the pyramid

= 64 + 202.386

= 266.386

Answer: 1/16

Step-by-step explanation:

Given that there are 4 green marbles, when Dan takes a marble the first time, the probability is 1/4 as there are 4 green marbles. When he puts it back and draws another one, the probability is still 1/4 because Dan didn't take the marble out of the bag(this is known as with replacement)

If you pull a card from a standard deck of 52 and then pull a second card without replacing the first card, you have about a ____ chance(round to nearest percent) of pulling out a face card, followed by on ace.

Answers

The probability that you pull a card from a standard deck of 52 and then pull a second card without replacing the first card is 2%

How to determine the probability?

The given parameters are:

Cards = 52

Face card = 12

Ace = 4

The probability of selecting a face card is:

P(Face card) = 12/52

Now, there are 51 cards.

The probability of selecting an ace is:

P(Ace) = 4/51

The required probability is:

P = 12/52 * 4/51

Evaluate

P = 0.0181

Express as percentage

P = 1.81%

Approximate

P = 2%

Hence, the probability is 2%
