What the median number for 4, 8 10 5 9

2 answers:

8 0

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.

Solve this system of equations using substitution:

The substitution method means you replace the variable in one equation with the other equation, so your new equation is x+4x-8=10. Add 10 to both sides to get 5x=18. Divide both sides by 5 to get x=3.6. This is a weird equation, but then to get y, work backwords. 3.6 times 2=7.2. 7.2-4=3.2 y=3.2. Finally to finish checking solve the equation as normal. 3.6+6.4=10. I hope this helped! Please give brainliest!
Your final answer is x=3.6 y=3.2

Use reciprocal to find 1/7p=3

1/7p = 3
Multiple both sides by 7

7 x 1/7p = 7 x 3
Then cross multiply

P= 21
