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.

btw, when Pythagoras said the square of this equals that and so on, he really meant the square or square area.

Answer:

  C.  90

Step-by-step explanation:

The numbers being multiplied are "factors." The result of multiplication is a "product." In this problem, the product is 90.

Answer:

Step-by-step explanation:

You already have the slope. It is + 1 as in y = (+1)x when you have been given

y = x + b

That means all you need do is subtract to find out what  b is

y =   x + b

x = 5

y = 11

Difference is 11 - 5 = 6

Try it a couple more times.

x = 10

y = 16

y = x + b

16 = 10 + b        Subtract 10

16 - 10 = b

b = 6 just as it did before.

y = x + b

x = 20

y = 26

26 = 20 + b      Subtract 20

26-20 = b

b = 6

So ? = 6

Answer:

1

Step-by-step explanation:

In sohcahtoa:

Cos (c) = adjacent (a) / hypotenuse (h)

cosA = adjacent / hypotenuse. The hypotenuse is 4.24 (the side opposite the right angle) and the side next to A is 3, so cosA = 3/4.24

cosB = adjacent/hypotenuse. The side next to B is 3, so cosB = 3/4.24 as well

Therefore, cosA = cosB

cosA/cosB = cosA/cosA = 1

Answer:

13

Step-by-step explanation:

add 3/4 and 3/4 to get 6/4 then get 1/2 times the bottom and the top but 2 to get 2/4 so then do 6/4 - 2/4 to get 4/4 or 1

add 10,8 to get 18 then subtract 6 to get 12 then all the 1 and you get your answer. Hope this helped

Answer:

13

Step-by-step explanation:

Convert 10 3/4

to an improper fraction.

43/4 + 8 3/4 − 6 1/2

Convert 8 3/4

to an improper fraction.

43/4 + 35/4 − 6 1/2

Convert 6 1/2

to an improper fraction.

434 + 354 − 132

Combine fractions.

78/4 + −13/2

Simplify each term.

39/2 − 13/2

Combine fractions.

Answer:

80 square metres

Step-by-step explanation:

A = L× w

= 72×20

= 1440

answer ÷ 18 = 80

Answer:

see explanation

Step-by-step explanation:

9W + 1 = 19 ( subtract 1 from both sides )

9W = 18 ( divide both sides by 9 )

W = 2

Answer:

180

Step-by-step explanation:

add 1% to 31.50 to get 31.815

then take the total 5276.70 and divide by 31.815

Answer:

55º

Step-by-step explanation:

The 125º angle makes a straight angle (180º) with the one next to it. This makes the angle next to it (adjacent angle) 55º. According to the rules of a transversal, the adjacent angle said above and angle 2 are alternate interior angles, making them equal.

We need slope/rate of the table

[tex]\\ \sf\longmapsto m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\\ \sf\longmapsto m=\dfrac{4-2}{6-3}[/tex]

[tex]\\ \sf\longmapsto m=\dfrac{2}{3}[/tex]

Slopes of all options

Option D is correct

Option

Answer:

The black car

Step-by-step explanation:

First, we need to fin the mile to gallon ratio.

To get this we would divide the number of miles by the gallon for each car

Green Car:

18.4/0.8

23 miles per gallon

Black car:

17.4/0.75

23.2 miles per gallon

In conclusion, The black car would travel further on one gallon of gas than the green car would.

Hope this helps!!

Answer:

51°

Step-by-step explanation:

angle2 is equal to 51 degrees

Answer:

∠2 = 51°

Step-by-step explanation:

These are consecutive interior angles that add up to 180°. Same as the other problem, you can solve for the angle like this:

480 because 50% is just haf and half has to be equal to the 240 so you just add 240 to 240

Step-by-step explanation:

The answer is C because 1 times 20 is 20 and .5 times 20 is 10 then you get 30

Answer: C.) $30.00

Step-by-step explanation: If 1.5 U.S. dollars equals 1 euro, then 1*20 would be 20 euros. So then, you could multiply 0.5*20 to get 10. Finally, you add $10 + $20 to get $30 U.S. dollars.

0.5*20= $10

20+10= $30

Answer:

290

Step-by-step explanation:

(16+13)(12-2)= 29 * 10 = 290

Answer:

290

Step-by-step explanation:

(16+13)(12-2)

29*10

290

Given data

height (h) = 25 m ,

velocity (v) = ?

we know that,

                    v²-u² = 2as

                     initial velocity (u) = 0,

                                               a = g = 9.8 m/s ,

                 Now the equation becomes,

                                    v² = 2 × g × h

                                        = 2 × 9.8 × 25

                                    v² = 490.5

                                    v = √490.5

                                   v = 22.1 m/s

Therefore answer is C , i.e., 22 m/s

Answer:

10x - 2y

Step-by-step explanation:

simplify the expression.

8x–2y + x + x

combine numbers that have the same variables

8x + x + x

*those x have 1 coefficient each.

it will be 8x+1x+1x = 10x then –2y

10x–2y.
