Mean is the average of a data set, which can be found by adding up all the data values and then dividing the sum by the amount of data values.

Median is the middle number of a data set. It is found by ordering the values from least to greatest and then finding the middle number. If there is an even amount of values, the mean of the two middle numbers must be found.

Mode is the number that appears most frequently in the data set.

20) -5(1 - 5x) +5(-8x - 2) = -4x – 8x
Alchen [17]

Answer:

x = -5

Step-by-step explanation:

-5(1 - 5x) +5(-8x - 2) = -4x – 8x

First lets simplify each side of the equation.

-5+25x-40x-10 = -4x-8x

Combine like terms

-15x-15=-12x

Add 15x to both sides (addition property of equality)

-15=3x

Divide each side by 3 (division property of equality)

x=-5

The answer is x = -5

valina [46]

This is the formula to solve for the vertex.

Example Question:

Find the vertex of y = -0.5x^2 + 100x

-b/2a = -100/2(-0.5) = -100/-1 = 100

The x coordinate of the vertex is 100.

Best of Luck!

P.S. this is 1000th question i've answered :)

1. Solve the absolute value equation, if possible. If there is no solution, explain why.
dexar [7]

Answer:The absolute value of a number is its distance away from zero. That number will always be positive, as you cannot be negative two feet away from something. So any absolute value equation set equal to a negative number is no solution, regardless of what that number is.

Step-by-step explanation:

Help pleasee asaapp im lost
avanturin [10]

Answer:

C

Step-by-step explanation:

The area of a circle is pi * r^2.  The radius is 7 because the diameter is 14 so the radius is 14/2.  The square of 7 is 49.  Pi is approximately 3.14, so 49 * 3.14 is about 154.
