Answer:

increase

Step-by-step explanation:

Given data is: 71, 67, 67, 17, 69, 84, 21, 87

Arranging in ascending order we find: 17, 21, 67, 67, 69, 71, 84, 87

Here N = 8 (Even number)

N/2 = 4 and N/2 + 1 = 5

4th term = 67, 5th term = 69

-> median = Sum of 4th and 5th term/2 = (67 + 69)/2 = 132/2 = 66

Now, when one of the 67 is replaced by 71, the new data set in ascending order will be: 17, 21, 67, 69, 71, 71, 84, 87

Here, 4th term = 69, 5th term = 71

New median = (69 + 71)/2 = 140/2 = 70

-> new median > initial median

CONCLUSION: Median will increase if the number 71 replaced one of the 67's in the set.

11 5/8 in = 11.625 in

9 3/4in = 9.75 in

10 1/2 in= 10.5 in

11.625+9.75+10.5= 31.875in

To find the average divide the total of inches by the amount of pieces there are to find the average:

31.875 / 3 = 10.625in

Someone help find the value of these music notes !!!

Elodia [21]

Answer:

See below

Step-by-step explanation:

1) 4/16 + 1/4 = 1/4 + 1/4 = 2/4 = 1/2 note

2) 4/16 + 2/8 = 1/4 + 1/4 = 2/4 = 1/2 note

3) 1/16 + 1/8 = 1/16 + 2/16 = 3/16 note (sixteenth note with a dot)

4) 1/4 + 1/16 = 4/16 + 1/16 = 5/16 note (sixteenth note with 2 dots)

5) 1/4 + 2/16 = 4/16 + 2/16 = 6/16 = 3/8 note (eighth note with dot)

6) (1/8+1/16)+1/8 = 2/8 + 4/16 = 4/16 + 4/16 = 8/16 = 1/2 note

7) 2/8 + 1/16 = 4/16 + 1/16 = 5/16 note (sixteenth note with 2 dots)

8) 2/16 + 2/16 = 4/16 = 1/4 note

9) (2/16+1/8)+1/4 = 2/16+2/16+4/16 = 8/16 = 1/2 note

10) 1/16 + 1/16 = 2/16 = 1/8 note

11) 1/16 + 1/8 = 1/16 + 2/16 = 3/16 note (sixteenth note with a dot)

12) 1/4 + 1/16 = 4/16 + 1/16 = 5/16 note (sixteenth note with 2 dots)

13) 1/4 + 2/16 = 4/16 + 2/16 = 6/16 = 3/8 note (eighth note with dot)

14) (1/8+1/16)+1/8 = 2/8 + 4/16 = 4/16 + 4/16 = 8/16 = 1/2 note

15) 4/16 + 1/4 = 1/4 + 1/4 = 2/4 = 1/2 note

16) 4/16 + 2/8 = 1/4 + 1/4 = 2/4 = 1/2 note

17) (2/16+1/8)+1/4 = 2/16+2/16+4/16 = 8/16 = 1/2 note

18) 1/16 + 1/16 = 2/16 = 1/8 note

19) 2/8 + 1/16 = 4/16 + 1/16 = 5/16 note (sixteenth note with 2 dots)

20) 2/16 + 2/16 = 4/16 = 1/4 note

21) (1/8+1/16)+1/8 = 2/8 + 4/16 = 4/16 + 4/16 = 8/16 = 1/2 note

22) 4/16 + 1/4 = 1/4 + 1/4 = 2/4 = 1/2 note

23) 4/16 + 2/8 = 1/4 + 1/4 = 2/4 = 1/2 note

24) (2/16+1/8)+1/4 = 2/16+2/16+4/16 = 8/16 = 1/2 note

25) 1/16 + 1/16 = 2/16 = 1/8 note

26) 2/8 + 1/16 = 4/16 + 1/16 = 5/16 note (sixteenth note with 2 dots)

27) 2/16 + 2/16 = 4/16 = 1/4 note

28) 1/16 + 1/8 = 1/16 + 2/16 = 3/16 note (sixteenth note with dot)

29) 1/4 + 1/16 = 4/16 + 1/16 = 5/16 note (sixteenth note with 2 dots)

30) 1/4 + 2/16 = 4/16 + 2/16 = 6/16 = 3/8 (eighth note with dot)

Bonus Question:

1/4 + 1/8 + 1/8 + 1/4 + 1/16 + 2/8 + 1/16 + 1/4 + 1/16 + (2/16+1/8) = 4/16 + 2/16 + 2/16 + 4/16 + 4/16 + 1/16 + 4/16 + 1/16 + 2/16 + 2/16 = 26/16 = 13/8 (whole note with dot tied with eighth note with 2 dots)

Write an equation of a circle that has the center at the origin and goes through (-3,-6)

dexar [7]

Answer:

$x^{2} +y^{2} = 45$

Step-by-step explanation:

General Equation of circle is

$(x-x_1)^{2} +(y-y_1)^{2} = r^{2}$ ----------- (1)

Here

$(x_1, y_1)= (0, 0)$

Radius r is distance from origin (x1, y1) to point (x2, y2)=(-3, -6)

$r=\sqrt{(x_2-x_1)^{2} + (y_2-y_1)^{2} }$

$r= \sqrt{(-3-0)^{2} + (-6-0)^{2} }$

$r= \sqrt{9+36}$

$r=\sqrt{45}$

Substituting values in equation (1)

$(x-0)^{2} +(y-0)^{2} =( \sqrt{45})^{2}$

$x^{2} +y^{2} = 45$
