$28.3 each I know this because you subtract 35 from 130 and you get 85. Then you do 85 divided by 3 and get 28.3
Answer:
67.6
Step-by-step explanation:
first, to find the mean you add up all the numbers and you would get 338. Next, you divide by how many numbers there are (5) so 338 divided by 5 equals 67.6
Answer:
That would be :
4x – 10 = x2 – 5x + 10 ( y = 4x - 10 is substitute for y)
PROOF: y + 5x = x² + 10
(4x - 10) + 5x = x² + 10
4x - 10 = x² -5x + 10
0 = x2 – 9x + 20 (liked terms are grouped and simplified)
PROOF: 4x - 10 = x² -5x + 10
4x = x² -5x + 10 + 10
0 = x² -5x -4x + 20
0 = x² - 9x + 20
Solving:
x² - 9x + 20 = 0
x² - 5x - 4x + 20 = 0
(x - 5) (x - 4) = 0
⇒ x = 4 (as question says) OR x = 5
Step-by-step explanation:

Answer:
The number of possible outcomes is 24×18.
The number of favorable outcomes are as follows: (3×5)+(8×7)+(13×6)
The probability is simply:
(3×5)+(8×7)+(13×6)/24×18=149/432
