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

18/X=2.4/28 find X plz help
yulyashka [42]
Cross multiply

18 / X = 2.4 / 28
so
18 * 28 = X (2.4)
and that becomes
504 = X * 2.4
then divide by 2.4
X = 210

Help please i dont wanna pull an all-nighter ill give 20 points i really dont care at this point
vagabundo [1.1K]

Answer:

y = 38, x = 90, x = 10, u = 6.2, w = 52, and v = 7.9

Step-by-step explanation:

Since the triangles are congruent, the angle and side lengths are also congruent. (CPCTC) Therefore, y = 38, x = 90, x = 10, u = 6.2, and v = 7.9. For w, we need to use the sum of angles in a triangle. So, we do 180 - 38 - 90 = w

w = 52.

What is the slope of a line that passes through the points (3, 1) and (2, 5) Please help! thanks!
Romashka-Z-Leto [24]
3=x1. 1=y1
2=x2. 5=y2

the formula to find slope is y2-y1 divided by x2-x1

so it would be 5-1 over 2-3 which would be 4/-2 and if you need it simplified it would be -2
