name for the quadrilateral.
Then, find x and y.

A) square x=80 y=5
B) rhombus x=80 y=5
C) rhombus x=100 y=10
D) square x=80 y=10
E) rectangle x=100 y=7

Answers

Answer 1

Answer:

Step-by-step explanation:

quadrilaterals= 360 degrees, now if you sub 80 for x, 80 +100 is 180 x 2( counting the other side) so 180 x 2 is 360

*I know there is a better way to explain it, but this is a way i find it

D. 84 square units

Answers

Answer:

Step-by-step explanation:

12-9 = 3 square unit

10 x 3 = 30 square unit

9×6 = 54 square unit

54+30 = 84 square units

and thats the answer

The area of the polygon is 84 square units, option D is correct.

What is Area of Rectangle?

The area of Rectangle is length times of width.

The given polygon has two rectangles.

Area of rectangle with length 9 and width is 6 units

Area of rectangle 1 =9×6

=54 square inches

Now Area of rectangle with length 10 and width is 3 units

Area of rectangle 2 =10×3

=30 square inches

Total area = 54+30

=84 square units

Hence, the area of the polygon is 84 square units, option D is correct.

James invests $5400 in two different accounts. The first account paid 14 %, the second account paid 6 % in interest. At the end of the first year he had earned $580 in interest. How much was in each account?

Answers

Given:

Total invested amount = $5400

Rate of interest for first account = 14%

Rate of interest for second account = 6%

Total interest after one year = $580

To find:

The amount invested in each account.

Solution:

Let the amount invested in the first account be $x, then the amount invested in the second account is $(5400-x).

Total interest = 14% of $x + 6% of $(5400-x).

[tex]580=\dfrac{14}{100}x+\dfrac{6}{100}(5400-x)[/tex]

Multiply both sides by 100.

[tex]58000=14x+6(5400-x)[/tex]

[tex]58000=14x+32400-6x[/tex]

[tex]58000-32400=8x[/tex]

[tex]25600=8x[/tex]

Divide both sides by 8.

[tex]\dfrac{25600}{8}=x[/tex]

[tex]3200=x[/tex]

Now,

[tex]5400-x=5400-3200[/tex]

[tex]5400-x=2200[/tex]

Therefore, the amount invested in first account is $3200 and the amount invested in the second account is $2200.

It is desired to check the calibration of a scale by weighing a standard 10-gram weight 100 times. Let μ be the population mean reading on the scale, so that the scale is in calibration if μ = 10 and out of calibration if μ ≠ 10. A test is made of the hypotheses H0 : μ = 10 versus H1 : μ ≠ 10. Which of the three conclusions is best if H0 is rejected?

Answers

Complete question :

It is desired to check the calibration of a scale by weighing a standard 10 g weight 100 times. Let µ be the population mean reading on the scale, so that the scale is in calibration if µ = 10. A test is made of the hypotheses H0:µ = 10 versus H1:µ ≠ 10. Consider three possible conclusions: (i) The scale is in calibration, (ii) The scale is out of calibration, (iii) The scale might be in calibration.

Which of the three conclusions is best ifH0 is rejected?

Answer:

The scale is out of calibration

Step-by-step explanation:

The null hypothesis ; H0

H0 : μ = 10 ; if this hold true, then the scale is in calibration

Alternative hypothesis ; H1

H1 : μ ≠ 10 ; if this holds true, then the scale is out of calibration

If the Null hypothesis, H0 is rejected, it means that, there is significant evidence to support the alternative hypothesis ; that the scale is out of calibration.

Hence, the best conclusion is that, the scale is out of calibration.

Answers

The number of fences needed to build around the entire garden is 12.

What is a square?

A square is a two-dimensional figure that has four sides and all four sides are equal.

The area of a square is given as side².

We have,

Side of the square garden = 3 inches

Scale factor.

1(1/2) inches = 4 feet

3/2 inches = 4 feet

3 inches = 8 feet

Now,

Length of one fence.

= 2(2/3) feet

= 8/3 feet

Now,

The perimeter of the square.

= 4 side

= 4 x 3 inches

= 12 inches

= 4 x 8 feet

= 32 feet

Now,

The number of fences needed to build the fence around the garden.

= 32 ÷ 8/3

= 32 x 3/8

= 12 fences

Thus,

12 fences are needed to cover the entire garden.

Suppose we are interested in bidding on a piece of land and we know one other bidder is interested. The seller announced that the highest bid in excess of $10,200 will be accepted. Assume that the competitor's bid x is a random variable that is uniformly distributed between $10,200 and $14,500.
a. Suppose you bid $12,000. What is the probability that your bid will be accepted?
b. Suppose you bid $14,000. What is the probability that your bid will be accepted?
c. What amount should you bid to maximize the probability that you get the property?
d. Suppose you know someone who is willing to pay you $16,000 for the property. Would you consider bidding less than the amount in part (c)? Why or why not?

Answers

Answer:

0.4185;

0.8835;

$14500;

Step-by-step explanation:

Given that :

a = 10200

b = 14500

f(y) = 1 /(b - a) = 1/(14500 - 10200) = 1/4300 = 0.0002325

A.)

P(x <12000) = ∫fydy at(12000 ; 10200) = ∫0.0002325dy at(12000 ; 10200)

P(x < 12000) = 0.0002325(12000) - 0.0002325(10200) = 0.4185

B.)

P(x <14000) = ∫fydy at(14000 ; 10200) = ∫0.0002325dy at(14000 ; 10200)

P(x < 14000) = 0.0002325(14000) - 0.0002325(10200) = 0.8835

(c.) 14500 ; because competitor's bid is at most 14500

D.) No ; Because by bidding $14500 ; getting the property is certain ; once the property is gotten, then it could be resold for $16000, to make a profit of $1500 ; by bidding less, winning the bid becomes uncertain which may means the profit might be lost in the long run.

For this exercise, you will complete the TicTacToe Board that we started in the 2D Arrays Lesson.We will add a couple of methods to the TicTacToe class.To track whose turn it is, we will use a counter turn. 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.
