Answer: Qualititative, Nominal and Categorical
Explanation:
The variable is qualitative since it does not involve numerical data (i.e. numbers). Rather we're dealing with names or labels.
Since names or labels are involved, and there isn't really inherent order to them, we consider this qualitative data to be nominal.
We can also consider it categorical since each label is a category.
1.Does the relationship between number of people and the bill appear to be weak, moderate or strong?
2.Does the relationship between number of people and the bill appear to be linear?
3.The equation of the line of best fit is Bill = 5.80 + 11.15 · People. (y=5.80+11.15x) Sketch this line on the scatterplot.
4.Interpret the slope of the line of best fit in the context of this problem.
5.Note that the points in the scatterplot do not all lie on the line. What could explain this variability?
6.Use the equation of the line of best fit to estimate how much would you predict the bill to be for a party of 8?
7.There was one party of 8 whose bill was $82.50. Did they pay more than or less than the predicted amount? How much more or how much less did they pay?
The relationship depicts to be fairly strong and also linear as the points on the graph doesn't move far from a line.
What is the relationship about?The interpretation of the slope of the line of best fit in the context of this problem is that the additional person added to the party will bring or add about $11.15 to the bill above.
The variability can be shown or explained by the differences that are seen in what the parties in the graph has ordered to eat or drink.
Since the party of 8 paid were said to have paid (95 - 82.50 =12.50) therefore, 12.50 is known to be less than the predicted amount.

A ladder is leaning against a house at an angle of 35° at the roof line. The base of the ladder is 8 feet from the house. How long is the ladder to the nearest whole foot? Use a calculator if needed.
A. 27 feet
B.43 feet
C. 8 feet
D. 14 feet
E. 35 feet
Answer:
D
Step-by-step explanation:
Remark
What you are trying to solve for is the hypotenuse of a right triangle. You will use the sine to do it.
Givens
Base = 8 feet
angle = 35 degrees
hypotenuse = ?
Formula
Sin(35) = base / hypotenuse
Solution
Sin (35) = 8 / hypotenuse Multiply both sides by the hypotenuse
hypotenuse * sin(35) = hypotenuse * 8/hypotenuse
hypotenuse * sin(35) = 8 Divide by sin(35)
hypotenuse = 8/sin(35) Substitute value of sin(35)
hypotenuse = 8 / 0.5736
hypotenuse = 13.94
Answer
The ladder is about 14 feet long or D

Option B (Lucy says to multiply 4 x 4 = 16 because 2 x 4 = 8.) is the solution.

[tex]\left[\begin{array}{cc}2&8\\4&?\\5&20\end{array}\right][/tex]
Do you see a pattern here? Concentrate on the second row rather than the first. Both integers are multiplied by four, therefore 4 x 4 must be multiplied.

Dividing a decimal number that is ________ than 1 gives a quotient that is larger than the dividend.
Answer:
Suppose we want to divide 3 by 2.
By Long Division we first write 1 as the first digit as the quotient, then we subtract 2 from 3, then we add a zero to the remainder 1, and then add a decimal point after the quotient 1, then write 5 after the decimal point, getting the quotient as 1.5
I know it is indeed right as we can verify. But why do we add a zero and the decimal point in the quotient?
Thank you.
Answer:
less
Step-by-step explanation:
Dividing a decimal number that is less than 1 gives a quotient that is larger than the dividend.
For example :
Take 3/0.3 :
⇒ 3 / 0.3
⇒ 10
10 is greater than the dividend 3.

an angle is 10 degrees more than 3 times the measure of its compliment. find the measure of both angles
Answer:
20° and 70°
Step-by-step explanation:
complimentary angle sum to 90°
let x be the compliment then the angle is 3x + 10 , so
x + 3x + 10 = 90 , that is
4x + 10 = 90 ( subtract 10 from both sides )
4x = 80 ( divide both sides by 4 )
x = 20
3x + 10 = 3(20) + 10 = 60 + 10 = 70
the 2 angle measures are 20° and 70°

The area of a rectangular piano is 5 5/8 square yards, it's length is 1 1/2 yards. what's the patios width in yards.
pls show work
Answer:
3 3/4 yards
Step-by-step explanation:
The area of a rectangle can be found by multiplying length * width. Since we have the area of the patio and the length, all we need to do to find the width is divide 5 5/8 (area) / 1 1/2 (length) =3 3/4 yards (width).
To check if this is correct, we can solve 1 1/2 * 3 3/4 = 5 5/8 yards.

Solve for D: 48 = 12D - 30 + 6D. Round to nearest hundredths if applicable!
Answer:
D = 4.33
Step-by-step explanation:
⇒ 48 = 12D - 30 + 6D
⇒ 48 = 18D - 30
⇒ 18D = 78
⇒ D = 78/18
⇒ D = 26/6
⇒ D = 13/3
⇒ D = 4.33
The requried simplified value of the given expression is D = 4.33.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
What is rounding of values?The rounding of values is superseding a number with an inexact value that has a more ephemeral, more uncomplicated, or more direct representation.
Here,
48 = 12D - 30 + 6D
Simplify,
48 = 18D - 30
D = 78 / 18

Explanation:
[tex]f(x)= -13x^2+15\\\\f(x)= -13x^2+15*1\\\\f(x)= -13x^2+15x^0\\\\[/tex]
Each term of the polynomial function has an exponent which is an even number, therefore the function is even.
-------------
Another approach:
[tex]f(x)= -13x^2+15\\\\f(-x)= -13(-x)^2+15\\\\f(-x)= -13x^2+15\\\\[/tex]
Since f(x) = f(-x) for all x, this proves the function is even.

We have found one solution to the equations that the two equations intersect at the point (2.5,-1.5).
What are equations?The equation is actually a relationship between the numbers and the variables. In this question we have two equations y=2x²-6x+1 and y=-x+1 so by equating them we can find the value of x which is the intersecting point of the two lines.
Now the solution of the equations:-
y=2x²-6x+1
y=-x+1
2x²-6x+1 = -x+1
2x²=5x
x=5/2=2.5
y=-2.5+1=-1.5
Hence the one solution to the equations that the two equations intersect at the point (2.5,-1.5).

Thomas is taking out a business loan of $20,000 over 5 years. He is given an APR of 6.12% he would like his monthly payments to not exceed $350 a month. Looking at the first few rows of the amortization table below, will his monthly payment be below $350 ? How much over/ under will hi actual payments be from his goal of $350? How much over/ under will his actual payments be from his goal of $350 per month?
1. Thomas' monthly payment for the loan exceeds $350.
2. An excess monthly payment of $37.77 exists.
3. Thus, the actual monthly payment is $387.77.
What is interest?The interest is the finance charge for the loan, representing the cost of the time value of money.
The interest and the monthly payments can be calculated using an online finance calculator as follows:
Data and Calculations:Business Loan = $20,000
Down Payment = 0%
Loan Term = 5 years or 60 months (5 x 12)
Interest Rate = 6.12%
Monthly Mortgage Payment = $387.77
Total of 60 Mortgage Payments = $23,266.38 ($387.77 x 60)
Total Interest = $3,266.38
Thus, Thomas' actual monthly payment is $387.77.
