A linear regression equation is computed for a sample of n = 13 pairs of X and Y scores. For the analysis of regression testing the significance of the equation, what are the df values for the F-ratio?

Answers

Answer 1

Answer:

The degrees of freedom are

                         ν₁ = n₁ -1 = 13 -1 = 12

                          ν₂= n₂-1 = 13 -1 =12

Step-by-step explanation:

Step(i):-

Given size 'n' = 13

size of sample of X score     n₁ = 13

size of sample of Y score     n₂ = 13

The degrees of freedom are

                         ν₁ = n₁ -1 = 13 -1 = 12

                          ν₂= n₂-1 = 13 -1 =12

Test statistic formula

                    [tex]F = \frac{S_{1} ^{2} }{S_{2} ^{2} } if S_{1} ^{2} > S_{2} ^{2}[/tex]

16.8 is 10% of what number? Someone help TWT

Answers

Answer:

168

Step-by-step explanation:

16.8 = 10%

x = 100%

To get to 100%, you have to multiply 10 by ten and 16.8 by 10. Like this:

16.8 = 10%                   original equation

16.8 (10) = 10% (10)      * both sides by 10

168 = 100%                  simplify

Find the slope. Explain what the slope and y-intercept means for the situation. Be sure to use your labels when explaining the real-life situation.

Answers

Answer:

Slope: 25, y-intercept: 0

Step-by-step explanation:

Take any two points. I'm going to take (3, 75) and (4, 100).

How to find slope: change in y/change in x

Change in y --> 100 - 75 = 25

Change in x --> 4 - 3 = 1

25 ÷ 1 = 25.

Slope is 25

Since 3 · 25 = 75, the y-intercept is 0.

The y-intercept stands for how much money someone gets for working 0 days, so they get $0 for working/whatever situation they're in for 0 days.

A candy maker is mixing up some sugar syrup for use in making sweets. How much of 30% sugar syrup should she add to 12 liters of 20% sugar syrup to obtain a mixture that contains 26% sugar? Write your answer as a whole number or as a decimal rounded to the nearest tenth.

Answers

Answer:

She should add 18 liters of 30% sugar syrup

Step-by-step explanation:

Let the amount of sugar syrup be x

Mathematically;

30% of x liters + 20% of 12 liters = 26% of (x + 12)

So, we have

0.3x + 2.4 = 0.26x + 3.12

0.3x-0.26x = 3.12-2.4

0.04x = 0.72

x = 0.72/0.04

x = 18

Answer:

A-(x+4,y-5)

B- move 1 unit left and 7 units down

Step-by-step explanation:

A- 4 units right is x so

(x+4,y__)

5 units down is y so

(x+4,y-5)

B- move 1 unit left and 7 units down

because (x-1,y__) is going left because of the subtraction sign and its the x-coordinate, and (x-1,y-7) is down because its a Y-coordinate and sub so its going down.

TIP- Going left/down is always subtract/negative going right/up is positive/addition.

Use the graph to write a linear function that relates y to x .

Answers

Answer:

2y = x + 2

Step-by-step explanation:

Looking at the graph, we can see from one point to the next (from right to left), the x-value rises by 2 and the y-value by 1;

From this we can work out the gradient between two points using the formula, i.e. the change/difference in y divided by the change/difference in x:

[tex]m = \frac{dy}{dx} = \frac{1}{2}[/tex]

Joining the points gives a straight line, which means a constant gradient of ¹/₂

Use the line equation formula to get the function:

y - y₁ = m(x - x₁)

m = ¹/₂

x₁ = 0

y₁ = 1

y - 1 = ¹/₂.(x - 0)

y - 1 = ¹/₂.x

2y - 2 = x

2y = x + 2
