To find the median, add up the frequency column to find how many trains there were in total. There were 44 trains in total in this grouped frequency table, so work out 44 + 1 2 = 45 2 = 22.5. The median is therefore between the 22nd and 23rd values.
This is a combination problem.
The formula is n! / (r!(n-r)!
where n is the total number of people and r is the number of people to be picked.
n = 15, r = 4
15! / (4!(15-4)!)
15! / (4!*11!)
Total combinations = 1,365

(c + 3) + -2c + -1(1 + -3c) = 2
Reorder the terms:
(3 + c) + -2c + -1(1 + -3c) = 2
Remove parenthesis around (3 + c)
3 + c + -2c + -1(1 + -3c) = 2
3 + c + -2c + (1 * -1 + -3c * -1) = 2
3 + c + -2c + (-1 + 3c) = 2
Reorder the terms:
3 + -1 + c + -2c + 3c = 2
Combine like terms: 3 + -1 = 2
2 + c + -2c + 3c = 2
Combine like terms: c + -2c = -1c
2 + -1c + 3c = 2
Combine like terms: -1c + 3c = 2c
2 + 2c = 2
Add '-2' to each side of the equation.
2 + -2 + 2c = 2 + -2
Combine like terms: 2 + -2 = 0
0 + 2c = 2 + -2
2c = 2 + -2
Combine like terms: 2 + -2 = 0
2c = 0
Solving
2c = 0
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Divide each side by '2'.
c = 0

Blue: O
Yellow: O O O each box has 2 inside because the box from blue and the 3 boxes from yellow= 4 and 4 x 2=8 ounces that jenny used
Step-by-step explanation:
Since it says 3 times more than yellow paint, blue should have 3 boxes and the yellow should have 1 box. The total is 4 boxes divided by 8 is 2 ounces in each box. Hope this helps!!
