Construct a scatterplot and identify the mathematical model that best fits the data. Assume that the model is to be used only for the scope of the given data and consider only linear, quadratic, logarithmic, exponential, and power models. Use a calculator or computer to obtain the regression equation of the model that best fits the data. You may need to fit several models and compare the values of R2.

Answer:  

A line has a slope of zero. Which of the following points could this line pass through?

(3, -6) and (7, -6)

(-8, 6) and (8, -6)

(12, 9) and (12, 6)

(3, 4) and (4, 6)

(-8, 6) and (8, -6)

(12, 9) and (12, 6)

(3, 4) and (4, 6)

Step-by-step explanation:

The answer would be (3,-6) and (7,-6) because if the slope is zero it wouldn't go any where it would stay the same, and I'm pretty sure it would be negative.

|-21.5|

it doesn't matter which direction because its just furthest from 0 so you just need to find the highest number and you can ignore any negative signs

Answer:

Y = 1/2x + 2

Step-by-step explanation:

First you find (b) or the Y-intercept which is 2 (Y = mx + 2)

Then you do rise over run to find slope. Rise = 1. Run = 2. Slope (m) = 1/2

Now you have your answer Y = 1/2x + 2

Answer:

The larger angle is 144 degrees and the smaller angle is 36 degrees

Step-by-step explanation:

Because this is a  supplementary angle you have to find out what x is to solve  this equation [tex]2.4x+9.6x=180[/tex]

Because 2.4x and 9.6x are like terms we add them [tex]2.4x+9.6x=12x[/tex]

So now to find x we divide 180 by 12 to get 15  [tex]\frac{12x}{12} =\frac{180}{12}[/tex]

We replace the x with 15 [tex]2.4(15)+9.6(15)=36+144[/tex]

We add 36 and 144 which equals 180

Answer:

8 gallons at $7

12 gallons at $2

Step-by-step explanation:

x gallons at $7 with the remaining (20 - x) gallons at $2 to get 20 gallons at $4

x(7) + (20 - x)(2) = 20(4)

Distribute

7x + 40 - 2x = 80

Combine like terms

5x + 40 = 80

Subtract 40 from both sides

5x = 40

Divide both sides by 5

x = 8 gallons at $7

20 - x = 12 gallons at $2

Answer: hope this helps ♡

The fraction of computer and video game players that are 18 years old or more is 3/4.

Step-by-step explanation:

Under 18: 25% or 1/4

25% → 25/100 → 5/20 (divided by 5) → 1/4 (divided by 5)

18 years old or more: 45% (18 to 49) + 30% (50 or more) → 75% or 3/4

75% → 75/100 → 15/20 (divided by 5) → 3/4 (divided by 5)

An expression for the number of dollars he has left is: 124 - B = T

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbol; which can also be used to indicate the logical syntax's order of operations and other features.

We know that Ravi has 124$, we don’t need how much he spent So, for the money he’s spent we are using B to represent it.

The expression is:

124 - B = T

Consider that B is how much money he spent.

T is his total after.

quiz name: 5.18 Quiz: Model the Real World with Multistep Equations

Answer:fewer than 12

Step-by-step explanation:

a) 20.9

    The mean is calculated by adding up the scores and dividing the total by the number of scores, it is also called the average.

    First, we can count and see there are 11 players (makes sense for a football team). Adding up the ages gives us 19 + 19 + 20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23 = 230. Divide by 11 and we get a mean of of about 20.9!

b) 30

To figure this out, we will set up an equation that looks like this:

[tex]\frac{19 + 19 + 20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23+x}{12} =22[/tex]

And now we will solve:

[multiply both sides by 12] 230 + x = 264

[subtract 130 from both sides] x = 30

So the age of the new player should be 30!

Have a nice day!

very good question let's think of a satellite can see if there is a hurricane and do math and use rational numbers all the time the world is made out of math

Answer:

45

Step-by-step explanation:

The area of a triangle is height x width /2, so the answer is 45

When we multiply powers with the same base, we add the powers together. This will give us:

[tex]\frac{3^8*3^4}{3^2 * 3^8} \\\frac{3^{12} }{3^{10}}\\[/tex]

When we divide the fractions with the same base then we subtract the exponents:

3^12 / 3^10 = 3^12-10 = 3^2

I hope this helps! :)

what is this I have the same problem what's the answer

Answer:

2.5

Step-by-step explanation:

By matching the statistical measures with their corresponding values, we have:

Median: 23.5

Mean: 22.5

Mode: 20, 24, 25, 26

Lower Quartile: 21.5

Upper Quartile: 24.5

To match the statistical measures with their corresponding values, we need to analyze the dataset and identify the appropriate measures. Here's the breakdown:

Median: The median is the middle value of the dataset when it is arranged in ascending order. In this case, since we have 12 data points, the middle two values are 23 and 24. Therefore, the median is the average of these two values, which is 23.5.

Mean: The mean is calculated by summing up all the values in the dataset and dividing by the total number of values. Adding up the given values, we get 262. Dividing this sum by 12 (the number of values), we obtain a mean of 22.5.

Mode: The mode represents the value(s) that appear(s) most frequently in the dataset. In this case, the values 20, 24, 25, and 26 all appear twice, making them the modes of the dataset.

Lower Quartile: The lower quartile divides the dataset into four equal parts, with 25% of the data falling below it. To find the lower quartile, we need to locate the value that is greater than or equal to 25% of the data. In this case, the 25th percentile falls between the values 21 and 22. The lower quartile is the average of these two values, which is 21.5.

Upper Quartile: The upper quartile divides the dataset into four equal parts, with 75% of the data falling below it. Similar to the lower quartile, we need to locate the value that is greater than or equal to 75% of the data. In this case, the 75th percentile falls between the values 24 and 25. The upper quartile is the average of these two values, which is 24.5.

I think the best deal would be 14 oz

The 10 0z, 1 oz would be equal to 25 cents and when you add 4 oz the price would have been 3.50 if it was going off of the same ratio as the 10 oz bottle. the 16 oz bottle is the same ratio as the 10 oz bottle and the 18 oz bottle would be 30 cents per oz.
