In the context of probability, an experiment is a process:

First, he has to decide on a pair of shirts and he has 7 different colors to choices.

A value between 0 and 1, inclusive, describes the relative possibility (chance or likelihood) that an event will occur.

For each of those choices he has a choice of 7 different shirts, so that gives him 3 times 7 = 21 different shirts.

For each of those 21 possibilities, he has 21 times 3 = 63 different outfits, and some of them may be acceptable to wear in public.

It is simply,3*3*7=64 ways.

The number of favorable outcomes is divided by the number of possible outcomes.

When you square or cube a negative number is it still negative or does it become positive?
Fynjy0 [20]
When you square a negative number, the result is positive.
(-4)^2 = (-4)ª(-4) = 16

When you cube a negative number, the result is negative.
(-4)^3 = (-4)•(-4)•(-4) = -64

Negatives pair up and cancel out, so odd exponents always have one negative unpaired, making the result negative.

Suppose that Marlie had decided to apply for a private loan rather than a federal loan. She has
34kurt

Using simple interest, and considering a loan of $5,000, it is found that:

a) Her monthly payment is of $74.17.

b) She will pay back $8,900.

c) The total interest amount is of $3,900.

The amount of money after <u>t years</u> in <em>simple interest</em> is modeled by:

A(t) = A(0)(1 + rt)

In which:

  • A(0) is the initial amount.
  • r is the interest rate, as a decimal.

In this problem:

  • The loan is of $5,000, hence A(0) = 5000.
  • The APR is of 7.8%, hence r = 0.078
  • 10 years, hence n = 10

Item b:

A(10) = 5000[1 + 0.078(10)] = 8900

She will pay back $8,900.

Item a:

$8,900 will be paid in 10 x 12 = 120 months, hence:

M = \frac{8900}{120} = 74.17

Her monthly payment is of $74.17.

Item c:

<u>Loan of $5,000, pays back $8,900</u>, hence:

8900 - 5000 = 3,900

The total interest amount is of $3,900.

Add the opposite of the term not containing y, then divide by the coefficient of y.

... -1.4y = 2.1 -4.2x

... y = -3/2 +3x
