The regression line is not a good model because the residuals are not randomly distributed.

For a residual plot to represent a good model, the points on the residual plot must be randomly distributed across the coordinates.

From a regression, the residual is the difference between the observed values and the predicted values.  

Using the graph, we can see that the points that follow a pattern (or curve) regression line is not a good model because the residuals are not randomly distributed.

Answer:

(A)

(1) NO

(2) YES

(B)

(3) YES

(4) NO

(5) YES

Step-by-step explanation:

According to the triangle sum theorem, the three interior angles of any triangle add up to 180 degrees. So, if we add up the three angles given, to be a triangle, they have to add up to 180 degrees.

38 + 42 + 110 = 190

So, ( (1)  38, 42, 110 ) is not a triangle becuase it adds up to more than 180 degrees (1).

20 + 40 + 120 = 180

So, ( (2)  38, 42, 110 ) is a triangle because it adds up to 180 degrees (2).

For the lengths for a triangle, the length of one side of a triangle must be greater than the difference and less than the sum of the lengths of the other two sides. This is saying:

A-B < C

A+B > C

So to find if they can be, simply plug in the values.

False : 5 > 5

(4) is not a triangle

Answer:

r=4/63

Step-by-step explanation:

Divide each term in 9r=47 by 9 and simplify.

Answer:

[tex]r=\frac{4}{63}[/tex]

Step-by-step explanation:

1) Divide both sides by the same factor

[tex]9r=\frac{4}{7}[/tex]

[tex]\frac{9r}{9} =\frac{\frac{4}{7} }{9}[/tex]

2) Simplify

[tex]\frac{9r}{9} =\frac{\frac{4}{7} }{9}[/tex]

[tex]r=\frac{\frac{4}{7} }{9}[/tex]

[tex]r=\frac{\frac{4}{7} }{9}[/tex]

[tex]r=\frac{4}{63}[/tex]

The volume of the rectangular prism filled with unit cubes each measuring the value of the length given is 72ft³.

Hence, Option D) 72ft³ is the correct answer.

A rectangular prism is simply a three-dimensional solid shape with six faces which are rectangles.

The volume of a rectangular prism is expressed as;

V = l × w × h

Where l is length, w is width and h is height of the prism

A cube is a three-dimensional solid with six equal square-shaped sides.  

Given the data in the question;

To determine the volume of the rectangular prism, we substitute our given values into the expression above.

V = l × w × h

V = 4ft × 3ft × 6ft

V = 72ft³

Option D) 72ft³ is the correct answer.

Hence, the volume of the rectangular prism filled with unit cubes each measuring the value of the length given is 72ft³.

Answer: 1575

Step-by-step explanation:

Volume of Pyramid: b*l*h/2 = 21*9*7/3 = 441

Volume of Rectangular prism = V= lwh = (21*12*9)/2 = 1134 (divide by two because it is half of a rectangular prism)

441 + 1134 = 1575

The amount of square yards of fabric that Margo used to make each dress is; 1.5 sq. yds

We are told that;

Last year, she used 78 yd² to make 52 dresses

We are told that she used the same amount of square yards for each dress.

Thus, to find the  square yards of fabric that Margo used to make each dress, we just divide 52 by 78.

Square yards used for each fabric = 78/52 = 1.5 sq. yds

Answer:

Step-by-step explanation:

Solving system of symultaneous equation:

Let the cost of one roll of plain wrapping pair = x

Let the cost of one shiny wrapping paper = y

Amanda:

   Cost of 3 rolls of plain paper + cost of 3 rolls of shiny paper = $ 60

3*x + 3*y = 60

3x + 3y = 60 ------------------(I)

Molly:

 Cost of 1 roll of plain paper + cost of 9 rolls of shiny paper = $ 132

  x + 9y = 132 ---------------------(II)

         x  = 132 - 9y ---------------(III)

Substitute x = 132 -9y in equation (I)

  3*(132-9y) + 3y = 60

3*132 - 3*9y + 3y = 60

    396 - 27y + 3y = 60

         Combine like terms

            396 - 24y  = 60

       Subtract 396 from both sides

                  -24y  =  60 - 396

                  -24y   = -336

        Divide both sides by (-24)

                      y   = -336/(-24)

[tex]\sf \boxed{y=14}[/tex]

Now, substitue y = 14 in equation (III)

x = 132 - 9*14

    = 132 - 126

[tex]\sf \boxed{x = 6}[/tex]

cost of one roll of plain wrapping paper = $ 6

Cost of one roll of shiny wrapping paper = $ 14

Range for Arnold: 18; IQR: 12

Range for Jackson: 20; IQR: 13

Jackson's had the greatest spread.

Arnold's middle 50% had the least spread

Range = Maximum value - minimum value

Interquartile range (IQR) = Q3 - Q1

Range and IQR are both measures of variability. The larger the value, the more spread the data values in a data set are.

Range for Arnold's training times = 102 - 84 = 18

Range for Jackson's training times = 103 - 83 = 20

Therefore, Jackson's training times had the greatest spread.

Interquartile range for Arnold's training times = Q3 - Q1 = 99 - 87 = 12

Interquartile range for Jackson's training times = Q3 - Q1 = 100 - 87 = 13

Thus, Arnold's middle 50% of his training times had the least spread.

The range and interquartile range tells us that, Arnold's training times are more consistent than Jackson's.

1/9 converted to a decimal is 0.1 (it's repeating- I am not sure how to do that on brainly w/ the fancy - over it, so it's 0.111111111...)

so as a percent, it makes it 11.1% (repeating) or 11 [tex]\frac{1}{9}[/tex]% (which is a more exact solution)

2x + (-2x) + 6 = 6

0 + 6 = 6

Answer:

1/12 + 3/12 = 4/12 (or 1/3)

Step-by-step explanation:

we want to express

1/12 + 1/4 as 1/12 + something / 12

1/12 + 1/4 = 1/12 + something/12

we already have the 1/12 part, so we're left with

1/4 = something / 12

first, we can calculate (denominator we want) / (denominator we have) = 12/4 = 3

then, we want to multiply our current value (1/4) by our result of the multiplication divided by itself.

3/3 = 1

1/4 = 1/4 * 1 = 1/4 * 3/3 = 3/12

thus, our second value is 3/12

we then have 1/12 + 3/12

if we have the same denominators, we can simply add the numerators up

1/12 + 3/12 = (1+3)/12 = 4/12
