regression equation to be y = 0.496.1.3%,
The scatterplot and residual plot are shown.

Select the true statements.
O A. The model is a good fit because the patterns in the plots are both
curves.
B. The points in the scatterplot follow a line, so a linear model would
fit the data better.
O C. The residual plot changes direction, so a quadratic model would
fit the data better.
D. The model is not a good fit because there is a pattern in the
residual plot.
Answer:
B.)The points in the scatterplot follow a line, so a linear model would fit the data better
A.)The model is not a good fit because there is a pattern in the residual plot.
Step-by-step explanation:
The linear model would best fit the scatter plot while the quadratic model would fit the residual plot. The true statements are: B and C.
What is a Linear Model and a Quadratic Model?A linear model is appropriate for data points that lie along a straight line on graph. If the line is not straight but curved and changes direction, a quadratic model is a better model for such data.
Thus, since the data points on the scatter plot are on a straight line, a linear model would fit the data.
For the residual plot that changes direction, a quadratic model would better fit the data.
The true statements are therefore: B and C.

Step-by-step explanation:
What is the next whole number after 267 In base 8
The next number would be 270₈. The given number has an digit expansion of
267₈ = 2•8² + 6•8¹ + 7•8⁰
If x is the next number, then adding 1 to the both sides gives
x = 2•8² + 6•8¹ + 7•8⁰ + 1
x = 2•8² + 6•8¹ + 7•8⁰ + 1•8⁰
x = 2•8² + 6•8¹ + 8•8⁰
x = 2•8² + 6•8¹ + 1•8¹
x = 2•8² + 7•8¹
x = 2•8² + 7•8¹ + 0•8⁰
and so x = 270₈.
The following ordered pairs represent a function.
(-2,-4) (-1, -2) (0, 0) (1, 2) (2, 4)
Which two ordered pairs can be added to the given set and still have the set represent
a function?
Answer:
(-3,-6) and (3,6)
Step-by-step explanation:
First, use process of elimination on the answer choices with x coordinates already used in the relation, because a value of x cannot have 2 outputs, or y-values. This leaves you with 2 options. Hope I helped :D
The sum of two angles is 90°. The difference of twice the larger angle and the smaller angle is 105º. The system of linear equations:

The answer is 12
Step-by-step explanation:
3x² - 2xy + 4y²
Let x = -2
y = -1
3(-2)² - 2(-2)(-1) + 4(-1)²
= 3(4) - 2(2) + 4(1)
= 12 - 4 + 4

Answer:
For 5.) I believe the slope is 3/5, for 6.) the slope is -2/8 (-1/4 when simplified) and the y-int is 2, for 7.) the slope is 6/2 (3/1 when simplified), for 8.) the slope is -2/4 (-1/2 when simplified) + the y-int is -3, and for 9.) the slope is 1/6.
Step-by-step explanation:
5.) the slope is 3/5 because it rises 3 and runs 5 (from the two plotted points)
6.) the slope is -2/8 (-1/4) because from the two points, it runs 8 and drops 2 (so -2) + when simplified its -1/4 because -2/8 divided by 2 on top and bottom would get you -1/4. And y-int is 2 because on the y-axis, the line is going through 2.
7.) the slope is 6/2 (3/1) because it rises 6 points and runs 2 (from the two points) and when simplified (6/2 divided by 2 on both top and bottom) would get you 3/1.
8.) the slope is -2/4 (or -1/2) because it runs 4 and drops 2 (which would be -2), and when simplified it gets you -1/2.
9.) the slope is 1/6 because between the two points, you rise one and run 6. Which gets you 1/6

The lengths two sides of a triangle are 10 cm and 11cm. Between what two measures should the length of the third side fall?
Step-by-step explanation:
a triangle can only be a triangle (all sides connect with each other), if every side is less than the sum of the other 2 sides.
so, the third side must be shorter than 10+11 = 21 and longer than 11-10 = 1, so that the side of 11 cm is shorter than the sum of the other two sides.
Answer:
1 < x < 21
Step-by-step explanation:
Given 2 sides of a triangle then the third side x is in the range
difference of 2 sides < x < sum of 2 sides , that is
11 - 10 < x < 11 + 10
1 < x < 21

(5 + 13 + 21 + ......... + 18) = ?
Correction:
5+13+21+...+181
First term = 5
Common difference = 13-5 = 8
Last term = an = 181
⇛a+(n-1)d = 181
⇛5+(n-1)(8) = 181
⇛ 5+8n-8 = 181
⇛ 8n-3 = 181
⇛ 8n = 181+3
⇛ 8n = 184
⇛n = 184/8
⇛ n = 23
Sum of the first n terms = Sn = (n/2)(a+an)
Sum of 23 terms = S 23
⇛(23/2)(5+181)
⇛ (23/2)(186)
⇛23×93

Answer:
x = 15
Step-by-step explanation:
The angles shown are supplementary angles. Supplementary angles add up to equal 180°
This means that 2x + 8 + 8x + 22 must equal 180
Note that we've just created an equation that we can use to solve for x
We now solve for x using that equation
2x + 8 + 8x + 22 = 180
combine like terms : 2x + 8x = 10x and 8 + 22 = 30
10x + 30 = 180
subtract 30 from both sides : 30 - 30 cancels out and 180 - 30 = 150
10x = 150
divide both sides by 10: 10x / 10 = x and 150 / 10 = 15
we're left with x = 15

A pianist charges $200 to perform at a restaurant. At the end of the night she collected her tips and left with a total earning of $310. Write an equation and solve for the amount she made in tips for the performance.
Answer:
310-200= T
Step-by-step explanation:
310 = 200 + x
Let’s break this down. 310 is their total earning, 200 is our set price for performing, and x represents how much she earned in tips.
310 = 200 + x
110 = x

What is 12,925 to the nearest ten thousand
Answer:
To round to the nearest 10,000, you look at the number immediately to the right. If this number is 5 or above, you add 1 to the column in question and zero all numbers to the right. If the number immediately to the right is 4 or less, you just zero all numbers to the right.
In this case, the 10,000 column is the column with the 1. The number immediately to the right is 2. This is 4 or less, so we set all numbers to the right of the 10,000 column to zero.
