What is mean median mode range?
Answer:
Mean- the average of data, meaning you add up all the numbers, and then divide the sum of the numbers by how many numbers there are. For example:
2, 2, 3, 4, 6, 6, 9.
7 numbers total.
2 + 2 + 3 + 4 + 6 + 6 + 9 = 32
32 ÷ 7 = 4.57
The mean would be 4.57.
Median- the middle point of the numbers. You cross off each of the numbers until you have one last number standing. If you have an even number of numbers, you find the middle of the last two numbers you crossed off. For example:
2, 2, 3, 4, 6, 6, 9
2, 3, 4, 6, 6
3, 4, 6
4
4 would be the median.
Mode- the largest number on the data.
Range- subtract the mode (largest number) from the smallest number to get range. For example:
2, 2, 3, 4, 6, 6, 9
9 - 2 = 7
7 would be the range.

which reflection carries parallelogram QRST onto itself?
Step-by-step explanation:
that 180° and 360° clockwise and counterclockwise rotations about this point will carry the parallelogram onto itself.
The parallelogram forms the angle [tex]180[/tex] degree and [tex]360[/tex] degree.
What is the parallelogram?
A parallelogram is a flat shape with four straight, connected sides so that opposite sides are congruent and parallel.
This means a parallelogram is a plane figure, a closed shape, and a quadrilateral.
If we rotate it in clockwise then it covers the angle [tex]180[/tex] degree and [tex]360[/tex] degree whether it is in clockwise or in anticlockwise.
Hence, the parallelogram forms the angle [tex]180[/tex] degree and [tex]360[/tex] degree.

Hi there!
We are given:

We can rearrange this into a logarithm:
[tex]log_4256 = \frac{1}{2}x[/tex]
Evaluate the left side:
4 = 1/2x
Multiply both sides by 2:
x = 8

hi <3
multiply the coefficient of x^2 with the last value:
2 x 3 = 6
you need to find a value that multiplies to give 6 and adds to give 5
this would be 3 and 2
now you have:
(x + 3)(x + 2)
we need to incorporate the 2 into it
you can divide the 2 by 2 so that part is fine. however, as 3 cant be divided by 2, you have to carry the 2 up as a coefficient for x
your final answer works out to be:
(2x + 3)(x + 1)
