Give the domain and range.
a. domain: {3, 0, 3), range: {3, 0}
b. domain: {-3, 0, 3), range: {0, 3}
c. domain: {3, 0,3), range:{-3.0}
d. domain: (3, 0, 3), range: {0,3}
Given:
The graph.
To find:
The domain and range of the graph.
Solution:
The three points on the graph are (-3,3), (0,0) and (3,3).
We know that, domain is the set of input values or x-values. So,
Domain = {-3,0,3}
We know that, Range is the set of output values or y-values. So, elements for range are 3,0,3. But a set contains only distinct elements. So, consider 3 once in range.
Range = {0,3}
Therefore, the correct option is b.

Step-by-step explanation:
A plastics manufacturer has developed a new type of plastic trash can and proposes to sell them with an unconditional 6-year warranty. To see whether this is economically feasible, 20 prototype cans are subjected to an accelerated life test to simulate 6 years of use. The proposed warranty will be modified only if the sample data strongly suggests that fewer than 90% of such cans would survive the accelerated test. After the accelerated life test on the 20 prototype cans, 13 survive. Does this indicate that the proposed warranty should be modified? Use =0.05.
Answer:
since -3.73 is less than 1.645, we reject H₀.
Therefore this indicate that the proposed warranty should be modified
Step-by-step explanation:
Given that the data in the question;
p" = 13/20 = 0.65
Now the test hypothesis;
H₀ : p = 0.9
Hₐ : p < 0.9
Now lets determine the test statistic;
Z = (p" - p ) / √[p×(1-p)/n]
= (0.65 - 0.9) /√[0.9 × (1 - 0.9) / 20]
= -0.25 / √[0.9 × 0.1 / 20 ]
= -0.25 / √0.0045
= -0.25 / 0.067
= - 3.73
Now given that a = 0.05,
the critical value is Z(0.05) = 1.645 (form standard normal table)
Now since -3.73 is less than 1.645, we reject H₀.
Therefore this indicate that the proposed warranty should be modified
a shoe store uses a 60% markup for all the shoes it sells what would be the selling price of a pair of shoes as a wholesale cost of $51
Answer:
81.60 is your selling price
Step-by-step explanation:
60% = 0.60
0.60 x 51 = 30.60
51 + 30.60 = 81.60
The selling price of shoes after a markup of 60% of the price will be equal to $81.60.
What is the Percentage?The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages. In other terms, it is a relationship where the worth of the entire is always considered to be 100.
As per the given information in the question,
The wholesale price of shoes = $51
There is a markup of 60% on every shoe.
Then the price of shoes will be,
$51 + $51 × (60/100)
$51 + 30.6
= $81.60

Sabrina plans to apply for a loan that requires a down payment at the end of this year what will help her reduce the total cost of the loan
Answer:
D. reducing the loan term and increasing the down payment
Step-by-step explanation:
Sabrina's loan balance should be lowered in order to have a lower interest. Therefore, she should "increase her down payment." An increase in down payment means a smaller loan balance.
In addition to this, she should also reduce the loan term because extending the term will most likely lead to an increase overall interest. Although the monthly payment is smaller than a shorter loan term, the overall amount Sabrina will pay is actually bigger.

What is the cross-sectional area of a cement pipe 2 in. thick with an inner diameter of 5 ft? Use pie 3.14.
Answer:
1.60 [tex]ft^{2}[/tex]
Step-by-step explanation:
Assuming that this is a cylindrical pipe, the area can be determined by applying the formula for calculating the area of a circle.
i.e Area = [tex]\pi[/tex][tex]r^{2}[/tex]
So that,
for the inner part of the pipe,
r = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{5}{2}[/tex]
= 2.5 feet
Area of the inner part of the pipe = [tex]\pi[/tex][tex]r^{2}[/tex]
= 3.14 x [tex](2.5)^{2}[/tex]
= 19.625
Are of the inner part of the pipe is 19.63 [tex]ft^{2}[/tex].
Total diameter of the pipe = 5 + 0.2
= 5.2 feet
r = [tex]\frac{5.2}{2}[/tex]
= 2.6 feet
Area of the pipe = [tex]\pi[/tex][tex]r^{2}[/tex]
= 3.14 x [tex](2.6)^{2}[/tex]
= 21.2264
Area of the pipe is 21.23 [tex]ft^{2}[/tex].
Thus the cross sectional area = Area of the pipe - Area of the inner part of the pipe
= 21.2264 - 19.625
= 1.6014
The cross sectional area of the cement pipe is 1.60 [tex]ft^{2}[/tex].

Answer:
Angle 1 is 140.
Step-by-step explanation:
Set angle 1 and angle 3 equal to each other since they are congruent to each other to get this equation 20x+60=30x+20. Subtract 20x on both sides to get this equation 60 = 10x + 20. Subtract 20 on both sides to get to 40 = 10x. Divide 10 on both sides to get your x-variable which is 4. Since you are solving for angle 1, plug in the x-value to get 20(4)+60. You should get 140 degrees as your final answer.

Round to the greatest place to estimate 23 x 1.75
IM GIVING AWAY 11 POINTS
Answer:
I think the answer is 992.5
After rounding off to the greatest place, the expression will be equivalent to 46.
What is rounding of in numbers?
Rounding numbers means adjusting the digits of a number such that it gives an estimated result. If the digit next to the digit which is to be rounded is less than 5, round down and if the digit is 5 or more than 5, than round up.
Given is to round off 23 x 1.75 to the greatest place.
We have the following expression -
23 x 1.75
We will no round of 23 as it would become 20, which is less than 23 itself. However, we will round off 1.75. Since, 75 > 49, we can round
1.75 to 2.00. Now, the expression becomes - 23 x 2.00. On multiplying, we get - 46
Therefore, after rounding off to the greatest place, the expression will be equivalent to 46.

I NEED HELP! DESPERATE! ATTACHED!
Answer:
x-1.77=13.73
x=15.50
Step-by-step explanation:
First, we susbitute variable x for the amount earned. Next as she spent 1.77 and has 13.73 remaining we derive x-1.77=13.73. Finally, add 1.77 to both sides to get x=15.5.
Answer:
The equation is x - 1.77 = 13.73.
The simplified version is x = 15.50.
Step-by-step explanation:
The equation is x - 1.77 = 13.73.
The simplified version is x = 15.50.
To get to this answer, we first need to plug the provided numbers into a simple equation.
We can assume that "x" (the unknown number) is the total. The total minus the amount of money spent, $1.77, will equal the new total, $13.73.
Therefore, x - 1.77 = 13.73.
Next, we need to solve the problem. By adding 1.77 to both sides of the equal sign, we effectively isolate the variable.
-1.77 + 1.77 = 0; 13.73 + 1.77 = 15.50.
We can, at last, come to the conclusion that x = 15.50.

a. Multiplying decimals less than one is taking a part of a whole.
b. Multiplying decimals less than one is finding a part of a part.
c. Multiplying decimals less than one can be shown as repeated addition.
d. Multiplying decimals less than one can be shown as repeated subtraction.
Answer:
b. Multiplying decimals less than one is finding a part of a part.
Step-by-step explanation:
A part of a given number implies a selected part of a given number which can be expressed as a fraction of the number. Example, the half of any number is [tex]\frac{1}{2}[/tex].
The product of a part and another part can be expressed as;
[tex]\frac{1}{3}[/tex] x [tex]\frac{2}{3}[/tex] = [tex]\frac{2}{9}[/tex]
or,
[tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] = [tex]\frac{1}{4}[/tex]
or,
[tex]\frac{1}{2}[/tex] x [tex]\frac{2}{3}[/tex] = [tex]\frac{2}{6}[/tex] = [tex]\frac{1}{3}[/tex]
The three examples shows: a part x a part.
Therefore, it would be observed that multiplying decimals less than one is the same as finding a part of a part.
