Answers

Answer:
The correct option is;
b. Stem and leaf plot

Step-by-step explanation:
A stem-and-leaf plot shows the data shape and the densities of the different classes in a graphical form such that the information in the data such as the data characteristics are self displayed by the data numbers arranged in the stem-and-leaf plot. The stem-and-leaf plot keeps the raw numerical data, in the form they were obtained and by their arrangement, outliers are easily spotted.

50% of 28 is 14.

What is (-3, -14) and (0, -9) written in slope intercept form? Thank you!

Answers

Answer:

Y= 5/3x + -9

Step-by-step explanation:

Well its

y=mx+b

m is slope

B is y intercept

To fidn y intercept, just make sure the X value of any coordiante given is 0 and the y value is not 0. So basically anything with (0, y), thats your y intercept.

Slope Is just

(y2-y1) / (x2-x1)

Answer:

y = 5/3x - 9

The equation for slope-intercept form would be y = mx + b.

Where y would be the total, m would be the slope, and b would be the y-intercept.

find the median: 10, 8, 14, 16, 13, 12.

Answers

Answer:

12.5

Step-by-step explanation:

10, 8, 14, 16, 13, 12

Organize the numbers from least to greatest

8, 10, 12, 13, 14, 16

Normally, the median would just be the number in the middle. However, because there are two numbers in the middle for this data set, add them and divide the sum by 2.

12+13=25

25÷2=12.5

Therefore, the median is 12.5.

I hope this helps!

12.16 is the answer 10+8+14+16+13+12=73 and 73 divided by the amount of numbers there which is 73/6=12.16

Garret invested $12,000 at an annual interest rate of 6%. How much money would Garret have had to invest at 10% so that the combined interest rate for both investments was 7% over the year?

Answers

Step-by-step explanation:

To determine how much money Garret would have had to invest at 10% in order to achieve a combined interest rate of 7% over the year, we can set up the following equation:

(12000 * 0.06) + (x * 0.10) = (12000 + x) * 0.07

Let's solve this equation to find the value of 'x', which represents the amount Garret would have had to invest at 10%:

720 + 0.10x = 0.07(12000 + x)

Simplifying the equation:

720 + 0.10x = 840 + 0.07x

0.10x - 0.07x = 840 - 720

0.03x = 120

x = 120 / 0.03

x = 4000

Therefore, Garret would have had to invest $4,000 at a 10% annual interest rate in order to achieve a combined interest rate of 7% over the year.

Garrett would have to invest 4000 at 10%

Dani experimented with a dollar bill and the copy machine a dollar bills length is 6.1 inches and width is 2.6 inches, she reduced the dollar bill so its length was 80% of its original size. What is the length of the copy of the dollar bill? please show how you figured it out. NO LINKS

Answers

Answer:

The length of the copy of the dollar bill is 4.88 inches in length and 2.08 inches in width.

Step-by-step explanation:

If Dani wants to make a smaller copy of a dollar bill and reduce its size to 80%, you will need to multiply the dollar bills original length by 8%.

80% = 0.8

0.8 x 6.1 = 4.88

80% = 0.8

0.8 x 2.6 = 2.08

8% I think not for sure! Hope this helped.

This is already declared as a private instance variable.Create a getTurn method that returns the value of turn.Other methods to implement:printBoard()- This method should print the TicTacToe array onto the console. The board should include numbers that can help the user figure out which row and which column they are viewing at any given time. Sample output for this would be: 0 1 20 - - - 1 - - - 2 - - - pickLocation(int row, int col)- This method returns a boolean value that determines if the spot a user picks to put their piece is valid. A valid space is one where the row and column are within the size of the board, and there are no X or O values currently present.takeTurn(int row, int col)- This method adds an X or O to the array at position row,col depending on whose turn it is. If its an even turn, X should be added to the array, if its odd, O should be added. It also adds one to the value of turn.checkWin()- This method returns a boolean that determines if a user has won the game. This method uses three methods to make that check:checkCol- This checks if a player has three X or O values in a single column, and returns true if thats the case.checkRow - This checks if a player has three X or O values in a single row.checkDiag - This checks if a player has three X or O values diagonally.checkWin() only returns true if one of these three checks is true.public class TicTacToeTester{ public static void main(String[] args) { //This is to help you test your methods. Feel free to add code at the end to check //to see if your checkWin method works!
