Each week, Bailey earns $12 per hour for the first 40 hours she works, and $18 for each hour of work after 40 hours. Her weekly earnings are a function of the amount of time she works.
Which function models the amount of money that Bailey earns?
the answers are graphs
The function model for the amount of the money that Bailey earns is,
Regular earning +overtime pay=total earnings.
We have given that the
12$ =1hours
first 40 hours in a week
and 18$ for each hour after a week.
We have to determine the function models the amount of money that bailey earns
What is the formula for regular earning?
regular hour × regular rate=regular eaning
40(12)=480$
overtime hours × overtime rate=overtime pay
Regular earning +overtime pay=total earnings
Here we don't know the overtime hours
Therefore we are unable to calculate total earnings.

Determine whether the sequence converges or diverges. If it converges, give the limit.
9, 27, 81, 243,
The sequence diverges because the value of the absolute common ratio r is greater than the 1.
What is convergent of a series?A series is convergent if the series of its partial sums approaches a limit; that really is, when the values are added one after the other in the order defined by the numbers, the partial sums getting closer and closer to a certain number.
We have series:
9, 27, 81, 243....
The above series is a geometric progression with common ratio r is 3
[tex]\rm r =\dfrac{27}{9}[/tex]
r = 3
We know the formula for a geometric sequence:
[tex]\rm S_n = 9(3)^n[/tex]
[tex]\rm S_n = 3^{n+2}[/tex]
A geometric series converges only if the absolute value of the common ratio:
r < 1 and
It diverges if the ratio ≥ 1
Here the value of r = 3 which is greater than the 1 so the sequence diverges.
Thus, the sequence diverges because the value of the absolute common ratio r is greater than the 1.

The question:
Divide. give the quotient and remainder. 4374/5
(This is from Aleks)
Answer:
Q: 875 R: 4
Step-by-step explanation:
If you dont like doing long division, try plugging values in usling a calculator! Estimate tht 5*8=40, and then, 5*800 must then equal 4000, which is pretty close to 4374
5*7=35, so the 5*70 must equal 350
5*4 equals 20, so when you add these values up you get...
4000+350+20...
or 4370
and, since 4374-4370 equals 4, your remainder would be 4!

A coin is Flipped 3 times. What IS the probability that the coin lands heads up once and tails up twice if order does not matter?
Answer:
The probability that the coin lands heads up once and tails up twice is .375, or 3/8.
Step-by-step explanation:
Check the conditions for a binomial distribution problem:
Define success = heads and failure = tails.The number of trials is fixed; n = 3.Each coin flip is independent of the other.Probability p = .5 of getting either heads or tails.We need to use combinations to determine the probability of getting one success (one head) and two failures (two tails).
The combination would be 3 choose 1: [tex]p = {3 \choose 1} (.5)^1(.5)^2[/tex].
There is one success and two failures, denoted by the superscripts above the probability p = .5.
Use a calculator to evaluate and we get:
[tex](3)(.25)(.5) = .375[/tex]The probability that the coin lands heads up once and tails up twice is .375, or 3/8.

A store uses binary numbers to assign a unique binary sequence to each item in its inventory. What is the minimum number of bits required for each binary sequence if the store has between 75 and 100 items in its inventory?.
Answer:
Introduction:
Binary numbers are used by different departmental stores to keep track of their inventory.
Explanation:
For this the minimum binary numbers should be 8 bits which can represent 256 unique values.
If a store needs to represent its inventory items between 25 to 75, it should use at least 8 bits which can formulate a eight bit number for every item.
