The table below represents the closing prices of stock ABC for the last five days. What is the r-value of the linear regression
Mekhanik [1.2K]

Answer:

C. -0.68427

Step-by-step explanation:

Enter the data into a graphing calculator.

First decide which is the independent and which is the dependent variable.  Since the value of the stock depends on the day, value will be dependent and day will be independent.

This means that the days will be entered into the first list and the values will be entered into the second list.

Entering these and running the linear regression, we find the r-value to be -0.68427 .

Aneli [31]

Answer:

Thus, option “c” 10% is correct.

Step-by-step explanation:

The percentage of students that like dubstep = 30%

The percentage of students that like trance music = 25%

The percentage of student that wants only house music = 20%

The percentage of students that like bot dubstep and trance = 15%

Now we have to find the percentage of students that like trance music but nor dubstep.

The percentage of students that like the trance music but nor dubstep = 100% - 30% – 25 % - 20% - 15%

The percentage of students that like trance music but nor dubstep = 10%

Thus, option “c” 10% is correct.

Wanahton is cooking a breadstick on a rectangular baking sheet measuring 9\dfrac129
salantis [7]

<u><em>Answer:</em></u>

The longest bread stick is approximately 16 in

<u><em>Explanation:</em></u>

The diagram representing the tray is shown in the attached image

From the diagram, we can note that the diagonal of the tray represents the hypotenuse of a right-angled triangle having legs 9.5 in and 13 in

<u>Therefore, to get the length of the hypotenuse, we can use the Pythagorean equation which is as follows:</u>

c² = a² + b²

where c is the length of the hypotenuse and a and b are the length of the two legs

<u>Substitute with the givens in the above equation to get the length of the hypotenuse as follows:</u>

c² = (9.5)² + (13)² = 259.25

c = 16.1 in which is approximately 16 in

<u>From the above, we can conclude that:</u>

The longest bread stick that can be fit straight along the diagonal of the tray is approximately 16 in

Hope this helps :)
