Create a scatterplot displaying the data in the table. Be sure to include a linear trend line. (2 points)
Can you show more information please?
Answer:
Using technology, the linear regression equation which models the data of the relationship between the number of customers served and tips received is :
y = 1.87x + 3.66
predicted amount of tip for 100 customers = $191
The predicted amount of tips received of 100 customers are served :
y = 1.87x + 3.66
x = 100 ; substitute x = 100 into the equation
y = 1.87(100) + 3.66
y = 187 + 3.66
y = 190.66
Hence, about $191 would be received on tips if 100 customers are recorded.
Using a regression calculator to make prediction from a data table :
Enter the x and y axis data into the appropriate column so that the calculator can display the actual data model. Hence, given a certain value of either variable, the predicted value of the required variable can be calculated from the model.

A proportional relationship between the number of pounds of potatoes x and the price in dollars y is graphed and the ordered pair 4, 3 is on the graphed line
Part a: what is the price of 1 pound of potatoes show your work
Part b: what does the ordered pair 8,6 on the graph represent? Explain in words.
Answer:
A proportional relationship between the number of pounds of potatoes (x) and the price in dollars (y) is graphed, and the ordered pair (4, 3) is on the graphed line. Part A: What is the price of 1 pound of potatoes? Show your work, including the proportion you used to determine the price. (8 points) Part B: What does the ordered pair (8, 6) on the graph represent? Explain in words. (2 points)
The point (4,3) means that 4 lbs. of potatoes = $3. Therefore, we have:
4 lbs / $3 = 1lb / x cross-multiply
4x = 3 divide by 4
x = 3/4 dollars = $.75 per pound
The point (8,6) means that 8 lbs. of potatoes = $6.

The simplified expression is [tex]27/(16x^6y^8).[/tex]
We have,
To simplify the expression [tex]4(3x^2y^4)^3 / (2x^3y^5)^4,[/tex] we can simplify each part separately and then divide.
Let's simplify the numerator first:
[tex](3x^2y^4)^3 = 3^3 * (x^2)^3 * (y^4)^3 = 27x^6y^{12}[/tex]
Now, let's simplify the denominator:
[tex](2x^3y^5)^4 = 2^4 * (x^3)^4 * (y^5)^4 = 16x^{12}y^{20}[/tex]
Now we can divide the numerator by the denominator:
[tex](27x^6y^{12}) / (16x^{12}y^{20})[/tex]
To divide the variables with the same base, we subtract their exponents:
[tex]27/16 * x^{6-12} * y^{12-20}[/tex]
Simplifying further:
[tex]27/16 * x^{-6} * y^{-8}[/tex]
To make the exponents positive, we can move the variables with negative exponents to the denominator:
[tex]27/(16x^6y^8)[/tex]
Therefore,
The simplified expression is [tex]27/(16x^6y^8).[/tex]

How is evaluating an expression with fractions like evaluating an expression with whole numbers? How is it different?
pls help
Answer:
Step-by-step explanation:
How do you evaluate fractions with whole numbers?
Multiply a fraction with a whole number by multiplying only the numerator. For example, 5 x 1/8 = 5/8. Multiply a fraction with another fraction by multiplying the numerators together and the denominators together. For example, 3/8 x 2/5 = 6/40 = 3/20.
Lucy wants to decorate the curved surface of a trash can that has a radius of 4 in. and a height of 12 in.
What is the area of the curved surface of the trash can she will need to decorate?
A trash can with radius 4 inches and height 12 inches.
12 in =30 cm
4 in = 10 cm
area of 1 circle= 3.14×10×10= 314 cm²
area of 2 circle= 314×2= 628 cm²
if u unfold the trash can the biggest surface(not the circle) will become a rectangle with two circles(628 cm²)
length of rectangle = circle circumference
= 2×3.14×10
=62.8 cm
area of rectangle= 62.8 × 30 = 1884 cm²
total area= 1884 + 628 = 2512 cm²

Laura is training to run a race. She keeps track of the number of miles she runs. She has been training for 7 weeks, and she has run a total of 63 miles. At what rate has she been running, in miles per week?
Explanation:
You divide the two values given to get 63/7 = 9.
We can think of it as if it was a ratio 63 miles: 7 weeks. Dividing both parts of that ratio by 7 will turn the "7 weeks" into "1 week".
You can check the answer by multiplying the 9 miles per week with the 7 weeks to get 9*7 = 63 miles total.

Green is with C, Blue is with A, Orange is with D, Purple is with B
Step-by-step explanation:
Hi!
So, it's been a while since I've done math like this, so the way I solved this was simply by doing the equations themselves and seeing which one matches. I'm sure there is an algebraic way to find which ones match, but this is all I know how to do :)
(By the way...I got the decimals by doing the fraction itself. 1 divided by 4(1/4th)=.25, as an example)
1(left)-7/1/4 is the same as 7/ .25. This is 28.
2(left) 2/3/ 4/5 is the same as .6666666/ .8. This is .83333repeating
3(left) 4/5 / 3/2 is the same as .8/1.5. This is .53333repeating
4(left) 1/4 / 1/7 is the same as .25/.143. This is 1.74(approx.)
1(right) 2/3 x 5/4 is the same as .66666 x 1.25 This is .8333 approx.
2(right) 1/4 x 7 is the same as .25*7. This is 1.75
3(right) 7*4 is 28.
4(right) 4/5 x 2/3 is the same as .8x.66666. This is .533
Now, we can match.
Green is with C.
Blue is with A
Orange is with D
Purple is with B
