Graphically, the MEDIAN of a density curve is the equal-area point, the point with half the area under the curve to its left and the other half to its right. The quartiles divide the area under the curve into quarters.
Step-by-step explanation:
The median of a density curve is the equal-areas point: the point that divides the area under the curve in half. The mean of a density curve is the balance point, at which the curve would balance if it were made of solid material.

7/9 < 5/6
We find the LCM of 9 and 6 which is 18.
For the first fraction, 6 multiplied by 3 is 18 so we multiply both the numerator and denominator by 3 to get:
5/6 = 5*3/6*3 = 15/18
For the second fraction, 9 multiplied by 2 is 18 so we multiply both the numerator and denominator by 2 to get:
7/9 = 7*2/9*2 = 14/18
We can see that 5/6 is greater than 7/9.
7/9 <. 5/6

An appliance store decreases the price of a 19 inch television set 21% to a sale price of $475.19. What was the original price
Answers
Answer:
The original price of the TV was $609.51
Step-by-step explanation:
100% - 21% = 79%
Now the question were really asking here is "475.19 is 79% of what?"
475.19 = 0.79 * x
To get x we must take 475.19 and divide by 0.79, which is about 601.51
The original price of the TV was $609.51

y = 15 so 2/3 times 15 equals 30/3, which equals to 10
so far, you have 1/5 - 10 = 30
10 plus 30 equals to 40 so basically you have to find what times 1/5 equals to 40
200 times 1/5 is 40

k(x) = 6x -12
15 = 6x -12 . . . . substitute for k(x)
27 = 6x . . . . . . add 12
27/6 = x = 9/2 = 4 1/2 . . . . . divide by 6

Write an equation in slope intercept form for the line with slope - 3/4 and y-intercept -2. Then graph the line.
Answers
Answer:
y = (-3/4)x - 2
Step-by-step explanation:
Start with the slope-intercept form y = mx + b. Replace m with -3/4 and y with -2. We then have y = (-3/4)x - 2.
Graphing this line: Knowing that b = -2, plot the point (0, -2). Find the x-intercept by letting y = 0 in the above equation and solving for x:
0 = (-3/4)x - 2, or (3/4)x = -2, or x = (4/3)(-2), or x = -8/3. Plot this x-intercept (-8/3, 0). Finally, draw a line through the points (0, -2) and (-8/3, 0).

The perimeter of a rectangle is 48 inches. If the length is 2 more than the width, what is the length and width?
Only an algebraic solution is accepted
Answers
Answers:
Length = 13 inches
Width = 11 inches
=====================================================
Work Shown:
w = width, some positive number
w+2 = length, since it is 2 inches more than the width
P = perimeter of the rectangle
P = 2(width + length)
P = 2(w + w+2)
P = 2(2w+2)
P = 4w+4
We're told that the perimeter is 48 inches. So we'll set the previous result equal to 48 and solve for w.
P = 48
4w+4 = 48
4w = 48-4
4w = 44
w = 44/4
w = 11
The width is 11 inches.
w+2 = 11+2 = 13
The length is 13 inches.
----------------
Checking the answers:
P = 2(L+W)
P = 2(13+11)
P = 2(24)
P = 48
The answers are confirmed.
L + W = 24
(W + 7) + W = 24
W = 8.5 inches
L = 15.5 inches
