Answer:
144 boys and 384 girls
Step-by-step explanation:
8 girls to every 3 boys. You can make an equation to solve this: 8x + 3x = 528. 528 = 11x. Then divide 528 by 11 to get 48. x=48. 8(48) = 384 girls. 3(48) = 144 boys.
If you would like to solve the equation x^2 + 9x - 22 = 0, you can do this using the following steps:
<span>x^2 + 9x - 22 = 0
</span>(x - 2) * (x + 11) = 0
1. x = 2
2. x = - 11
The correct result would be x = 2 and x = - 11.
Answer:
Step-by-step explanation:
Using the mean concept, it is found that the average score of Adrian’s favorite team relative to its opponent using the observations Adrian made during the game is of -0.3333.
-----------------
The mean of a data-set is given by the sum of all observations divided by the number of observations.
Adrian looked the scores every 10 minutes in 2 hours, thus 12 times, as .
4 times ahead by 3 points, thus
4 times behind by 4 points, thus
At the other moments, the game was tied, thus the observation is 0.
Thus, the mean is of:
The average score of Adrian’s favorite team relative to its opponent using the observations Adrian made during the game is of -0.3333.
Answer:
both If's and a b
Step-by-step explanation:
I don't know for sure
9 1/2 = 19/2
(29/5) / (19/2)
When changing division to multiplication, flip the number (right hand side).
(29/5) * (2/19)
58/95
