Because the higher the number, tho more numbers it can be multiplied by.
The probability that a flight that departs on schedule also arrives on schedule
83%×68%=56%
First, you convert 2 3/4 to a improper fraction, which is 11/4. Then you multiply 4/5 with 11/4, after you cross simplify the fractions, you can multiply 1/5 with 11/1, which equals 2 1/5. Hope can help you a little bit. :)
So this is easy counting
so 5x^2-3x-9
we have 5 x^2's
-3 x's
-9
wat do we add to that to get
1 x^2's
-5 x's
+6
so we do each
5x^2+what=1x^2
subtract 5x^2
from both sides
what=-4x^2
first is -4x^2
then we have -3x to -5x
-3x+what=-5x
add 3x to both sides
what=-2x
second is -2x
-9 to 6
-9+ what=6
ad d9
what=15
last is 15
thereffor add -4x^2-2x+15
