The mean is 21. The median is 15. The mode is 15. The range is 16.
Answer:

Step-by-step explanation:
We can use the slope-intercept form of the equation of a line, y = mx + b, where m is the slope and b is the y-intercept.
From the graph, we see the line crosses the y-axis at y = 15. That means the y-intercept is 15, and we have so far y = mx + 15.
Now we need the slope. On the graph we see that for every 3 units up in y, there is 1 unit to the right in x. The slope is 3/1 = 3. m = 3. Now we add the slope to the equation.
y = 3x + 15
Answer: y = 3x + 15
Answer:
Area of bigger rectangle = length x breadth = 12 x 9 = 108 square cm
Area of small rectangle = length x breadth = 8 x 5 = 40 square cm
Area of the shaded region = Area of big rectangle - Area of small rectangle
= 108 - 40 = 68 square cm
Answer:
hello :
note :
the linear function of x have equation : y = ax + b
correct answer is : A) and C) and E)
A) : 3y = 2x -15
y = (2/3)x -15/3
y = ( 2/3)x -5 ..... when : a = 2/3 and b = -5
B) : 5(x+y)=-25
x + y = - 5
y = - x -5 ...... when : a = -1 and b = -5
C) y = 1
y = 0x +1 .....when : a = 0 and b = 1
