The price of sunglasses is greater original price and 0.45 is tax amount.
What is Tax?A tax is a mandatory fee or financial charge that a government imposes on a person or a business in order to raise money for public projects like building the greatest infrastructure and services.
Taxes are required financial contributions imposed by a government body, whether local, regional, or federal, on people or businesses. Tax revenues are used to fund a variety of government initiatives, such as Social Security and Medicare as well as public infrastructure and services like roads and schools.
Given:
Original price of sunglasses = $10.
Price according to cashier= $10.45
So, the price of sunglasses is greater original price.
and, the difference both price

Part A: A graph passes through the points (0, 2), (1, 3), and (2, 4). Does this graph represent a linear function or a non-linear function? Explain your answer in words
Part B: Write one example of a linear function and one example of a non-linear function.. (Use x and y as the variables) (10 points)
Answer:
Part A:
The graph passes through (0,2) (1,3) (2,4).
If the graph that passes through these points represents a linear function, then the slope must be the same for any two given points. Using (0,2) and (1,3). Write in slope-intercept form, y=mx+b. y=x+2
Using (0,2) and (2,4). Write in slope-intercept form, y=mx+b. y=x+2. They are the same and in graph form, it gives us a straight line.
Since the slope is constant (the same) everywhere, the function is linear.
Part B:
A linear function is of the form y=mx+b where m is the slope and b is the y-intercept.
An example is y=2x-3
A linear function can also be of the form ax+by=c where a, b and c are constants. An example is 2x + 4y= 3
A non-linear function contains at least one of the following,
*Product of x and y
*Trigonometric function
*Exponential functions
*Logarithmic functions
*A degree which is not equal to 1 or 0.
An example is...xy= 1 or y= sqrt. x
An example of a linear function is 1/3x = y - 3
An example of a non-linear function is y= 2/3x

Are 4x, 4y, and 4xy like terms?
In algebra, like terms are terms that have the same combination of variables raised to the same powers. Let's determine whether 4x, 4y, and 4xy are like terms.
The term 4x consists of the variable x raised to the power of 1, while the term 4y contains the variable y raised to the power of 1. Thus, both 4x and 4y have the same combination of variables raised to the same power. Therefore, they can be considered like terms. On the other hand, the term 4xy consists of both the variables x and y, each raised to the power of 1.
Although it includes both x and y, the arrangement of the variables is different from the previous terms. This means that 4xy is not a like term to either 4x or 4y. In conclusion, among the given terms, 4x and 4y are like terms, while 4xy is not. It is important to identify like terms in algebra to simplify expressions and combine similar terms for easier calculations.

The combined average weight of an okapi and a llama is 450 kilograms.
3 llamas, on average, weigh 190 kilograms more than an average okapi.
You want to find the average weight of each type of animal.
Answer:
An average Ilama weighs 160 kilograms and an average okapi weighs 290 kilograms.
Step-by-step explanation:
Let,
x be the average weight of a Ilamas
y be the average weight of an okapi
According to given statement;
x + y = 450 Eqn 1
3x = y + 190 Eqn 2
From Eqn 2
y = 3x - 190 Eqn 3
Putting this value of y in Eqn 1
x + (3x-190) = 450
x + 3x - 190 = 450
4x = 450 + 190
4x = 640
Dividing both sides by 4
[tex]\frac{4x}{4}=\frac{640}{4}\\x=160\\[/tex]
Putting x = 160 in Eqn 3
y = 3(160) - 190
y = 480 - 190
y = 290
Hence,
An average Ilama weighs 160 kilograms and an average okapi weighs 290 kilograms.
The head of maintenance at XYZ Rent-A-Car believes that the mean number of miles between services is 2135 miles, with a variance of 145,924. If he is correct, what is the probability that the mean of a sample of 40 cars would differ from the population mean by less than 29 miles
Answer:
0.36878
Step-by-step explanation:
Given that:
Mean number of miles (m) = 2135 miles
Variance = 145924
Sample size (n) = 40
Standard deviation (s) = √variance = √145924 = 382
probability that the mean of a sample of 40 cars would differ from the population mean by less than 29 miles
P( 2135 - 29 < z < 2135 + 29)
Z = (x - m) / s /√n
Z = [(2106 - 2135) / 382 / √40] < z < [(2164 - 2135) / 382 / √40]
Z = (- 29 / 60.399503) < z < (29 / 60.399503)
Z = - 0.4801364 < z < 0.4801364
P(Z < - 0.48) = 0.31561
P(Z < - 0.48) = 0.68439
P(- 0.480 < z < 0.480) = 0.68439 - 0.31561 = 0.36878
= 0.36878
Answer: 0.3688

Overhead is 1.5 times weekly labor cost. Material cost is $6 per pound.Week Output (units) Workers Material (lbs)1 30,000 6 4502 33,600 7 4703 32,200 7 4604 35,400 8 480
Answer:
Week 1 =3.03
Week 2 =2.99
Week 3=2.9
Week 4=2.83
Step-by-step explanation:
Computation for the multifactor productivity measure for each of the weeks shown for production of chocolate bars.
Using this formula
Week Multifactor productivity measure = (Output / Total Cost)
Where:
Output represent Quantity produced
Total cost represent Labor cost + Material cost + Overhead
Let plug in the formula
Week 1= 30,000/(40*12*6)+[(40*12*6)1.5]+(450*6)
Week 1 =30,000/(2,880)+(2,880*1.5)+2,700
Week 1 =30,000/(2,880+4,320+2,700)
Week 1=30,000/9,900
Week 1 =3.03
Week 2= 33,600/(40*12*7)+[(40*12*7)1.5]+(470*6)
Week 2 =33,600/(3,360)+(3,360*1.5)+2,820
Week 2=33,600/(3,360+5,040+2,820)
Week 2=33,600/11,220
Week 2 =2.99
Week 3= 32,200/(40*12*7)+[(40*12*7)1.5]+(460*6)
Week 3 =32,200/(3,360)+(3,360*1.5)+2,760
Week 3=32,200/(3,360+5,040+2,760)
Week 3=32,200/11,160
Week 3=2.9
Week 4= 35,400/(40*12*8)+[(40*12*8)1.5]+(480*6)
Week 4 =35,400/(3,840)+(3,840*1.5)+2,880
Week 4=35,400/(3,840+5,760+2,880)
Week 4=35,400/12,480
Week 4=2.83
Therefore the multifactor productivity measure for each of the weeks shown for production of chocolate bars is :
Week 1 =3.03
Week 2 =2.99
Week 3=2.9
Week 4=2.83

Abigail wants to ride her bicycle 30.4 miles this week. She has already ridden 7 miles.
If she rides for 3 more days, write and solve an equation which can be used to
determine m, the average number of miles she would have to ride each day to meet
her goal.
Answer:
3m + 7 = 30.4
m = 7.8
Step-by-step explanation:
3m, where m is the average number of miles per day, will represent how many miles she rides in the next 3 days.
She has already ridden 7 miles, so 7 has to be added to 3m in the equation.
Then, the equation has to be set equal to 30.4, because that is her goal for the week
Put this all together:
3m + 7 = 30.4
Solve for m:
3m + 7 = 30.4
3m = 23.4
m = 7.8
So, Abigail has to ride an average of 7.8 miles per day to meet her goal.

Number of Similar Preferences Number of Married Couples
All four 30
Three 128
Two 124
One 61
None 32
Suppose that a married couple is selected at random.
(a) Use the data to estimate the probability that they will have 0, 1, 2, 3, or 4 personality preferences in common. (Enter your answers to 2 decimal places.)
0 1 2 3 4
1 2 3 4 5
(b) Do the probabilities add up to 1? Why should they?
i. Yes, because they do not cover the entire sample space.
ii. No, because they do not cover the entire sample space.
iii. Yes, because they cover the entire sample space.
iv. No, because they cover the entire sample space.
(c) What is the sample space in this problem?
i. 0, 1, 2, 3 personality preferences in common
ii. 1, 2, 3, 4 personality preferences in common
iii. 0, 1, 2, 3, 4, 5 personality preferences in common
iv. 0, 1, 2, 3, 4 personality preferences in common
Answer:
a. Probability (0) = 36/375 = 0.096
Probability (1) = 61/375 = 0.162
Probability (2) = 124/375 = 0.330
Probability (3) = 128/375 = 0.341
Probability (4) = 30/375 = 0.08
b. iii) Yes, because they cover the entire sample space.
c. Obviously, the sample space in this problem is iv.
iv = {0,1,2,3,4} personality preferences in common.
Step-by-step explanation:
In this question, we are asked to calculated the probability of preferences in common.
As we know, the general formula for probability is:
Probability = Number of favorable outcome/ Total number of favorable outcomes
Data Given:
For 0 = 36
For 1 = 61
For 2 = 124
For 3 = 128
For 4 = 128
Total = 375 Married Couples
Probability (0) = Number of favorable outcomes/ Total Number of Favorable outcomes
Probability (0) = 36/375 = 0.096
Similarly,
Probability (1) = 61/375 = 0.162
Similarly,
Probability (2) = 124/375 = 0.330
Similarly,
Probability (3) = 128/375 = 0.341
Similarly,
Probability (4) = 30/375 = 0.08
b. Total Probability can never be greater than 1 and less than 0.
So, Probabilities of the sample will add up to 1
iii) Yes, because they cover the entire sample space.
Total Probability = P(0) + P(1) + P(2) + P(3) + P(4) = 1
Total Probability = 0.09 + 0.16 + 0.33 + 0.34 + 0.08 = 1
c. Obviously, the sample space in this problem is iv.
iv = {0,1,2,3,4} personality preferences in common.
