The median is equal to the average of the numbers
add up all of the numbers and divide that by the total number of numbers to get the average, or median
for example: the average of 13,20, 15, and 23 would be (13+20+15+23)/4=17.75

if you have the sequence of 4, 8, 10, 5, and 9, the average would be (4+18+10+4+9)/5 = 9

Hope that helps!

Actually, the median is not the same as the average.
The mean and the average are the same.
To find the median, put these numbers in order.
So 4, 5, 8, 9, 10. Now see which number is in the middle.
It is 8, so 8 is the median number.

Given the points A(0, 0), B(e, f), C(0, e) and D(f, 0), determine if line segments AB and CD are parallel, perpendicular or neit
Virty [35]

Answer:

Perpendicular

Step-by-step explanation:

Calculate the slopes m of the segments using the slope formula.

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

Parallel lines have equal slopes

The product of the slopes of perpendicular lines equals - 1

(x₁, y₁ ) = A(0, 0) and (x₂, y₂ ) = B(e, f)

m_{AB} = \frac{f-0}{e-0} = \frac{f}{e}

Repeat with (x₁, y₁ ) = C(0, e) and (x₂, y₂ ) = D(f, 0)

m_{CD} = \frac{0-e}{f-0} = - \frac{e}{f}

Thus AB and CD are perpendicular since \frac{f}{e} × - \frac{e}{f} = - 1

How is the graph of y=4(2)^x+3 translated from the graph of y=4(2)^x
Pie

Answer:

Vertical movement: Move up 3 units

or

Horizontal movement: Move left 3 units

Step-by-step explanation:

If your parent equation is f(x) = 4(2)^{x} and your child equation is f(x) = 4(2)^{x} + 3, then it has vertically moved up 3 units.

If your parent equation is f(x) = 4(2)^{x} and your child equation is f(x) = 4(2)^{x+3}, then it has moved horizontally left 3 units.
