21-(x+7)
how do i solve it.

Answers

Answer 1
Answer: 21 - (x + 7) We would multiple the numbers inside the parenthesis with -

21 - x - 7 Then we simplify

14 - x

Or if it’s equal to 0 and you need to isolate the x then it’s

x = -14

A Nashville-area radio station plays songs from a specific, fixed set of artists. The station has no DJ; instead, a computer randomly selects which songs to play. The songs themselves are picked randomly, and the same song may be played many times in a row. In the set of songs, 45% are sung by a female singer, 45% are sung by a male singer, and 10% are instrumental with no vocals. What is the probability that a particular set of 3 songs contains exactly 2 female singers and 1 male singer? (Hint: Be aware that there are multiple ways to achieve this pattern of songs.)

Answers

The answer is 27.3375%.

To calculate this, a multiplication rule is used. The multiplication rule calculates the probability that both of two events will occur. In this method, the possibilities of each event are multiplied.

So, we have three events occurring simultaneously:

1. set contains female singer: 45% = 0.45

2. set contains female singer: 45% = 0.45

3. set contains female singer: 45% = 0.45


Also, it should be taken into consideration that there are three set combinations:

female-female-male,

female-male-female,

male-female-female


So, the probability for one set of the song is:

0.45 × 0.45 × 0.45 = 0.091125

Therefore, the probability is multiple ways to achieve this pattern of songs):

3 × 0.091125 = 0.273375 = 27.3375%.

For the function f(x)=x^2-12 find (f^-1)(4)

Answers

f(x) = x^2 - 12
y = x^2 - 12
y + 12 = x^2
x = sqrt(y + 12)
(f^-1)(x) = sqrt(x + 12)

(f^-1)(4) = sqrt(4 + 12) = sqrt(16) = 4
(f^-1)(4) = 4

Sally needs to have some drywall and insulation work done in her house. She has received a quote from a professional drywall contractor to complete her repairs for $1,200. Her neighbor Steve says he can complete the same job for $800. Sally could use a credit card to pay the contractor, but Steve can only accept cash. Sally’s credit card has a 14% APR for credit purchases and a 32% interest rate for cash advances. Expecting to pay $50 of the principle plus appropriate interest each month, Sally estimates that it would take her 24 months to pay off the contractor balance and 16 months to pay off the cash advance balance. In the end, would it be cheaper for Sally to hire the contractor or her neighbor to complete the repairs?
