Mean: add all the values together and divide by how many numbers there are.
Example- 2+4+6+8+10=30
30/5=6. The mean is 6

Median: arrange the numbers in order from least to greatest (counting order). If there is more than one of any number make sure to put them all together. Then find the number in the middle. That's the median. If there isn't one number in the middle, take the two 'middle' numbers, add them together and divide by 2. That will be the median
Ex- 2, 4, 6, 8, 10 median is 6
Ex- 2, 4, 6, 8, 10, 12 6+8=14 14/2=7 median is 7

Mode: what number shows up the most often? Sometimes there might not be a mode if there are no repeated values.
Ex- 2, 4, 6, 6, 8, 10 the mode is 6, it is in the list more than any other number

Range: the difference of the greatest value and least value
Ex- 2, 4, 6, 8, 10 10-2=8. The range is 8
One thing that is the MOST helpful when finding all of these is to put all the numbers in counting order (least to greatest) before you try to do anything!

Sorry I can't be more specific, it's difficult to read the graphs and charts

Select the correct answer. Solve for x. (x - 4)(x - 4) = 0 A. -16 B. -4 C. 4 D. 16
Rzqust [24]

Answer:

C. 4

Step-by-step explanation:

To solve, set each parenthesis equal to the opposite side (0 in this case).

(x - 4)(x - 4) = 0

x - 4 = 0

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 4 to both sides:

x - 4 (+4) = 0 (+4)

x = 0 + 4

x = 4

Do the same for the other parenthesis:

x - 4 = 0

x - 4 (+4) = 0 (+4)

x = 0 + 4

x = 4

C. 4 is your answer.

Solve log x = 3.<br> x = 10,000<br><br> x = 3<br><br> x = 30<br><br> x = 1,000
ella [17]

Answer:

x = 1000

Step-by-step explanation:

Logarithms are just a base, exponent and answer, rearranged in a different order. No doubt you have seen "log" followed by a small font, low (subscript) number or letter, followed by a regular-size font number or letter. This is set equal to another number or letter. Your problem doesn't have that subscript (small font, low on the line) When this is not written, it is understood to be a 10. So your problem, rearranged to look like an exponent is:

10^3 = x

10 to the 3rd power is 10×10×10 which is

1000.
