Cool if badly worded question. They're called dice. "given than"?
P(sum of two dice is odd GIVEN one is 4)
Of the 36 pairs of dice rolls, eleven have one with a 4:
(4,1),(4,2),(4,3),(4,4),(4,5),(4,6),(1,4),(2,4),(3,4),(5,4),(6,4)
Six of eleven have an odd sum;
Answer: 6/11
20.
The sides of a 45/45/90 triangle are in ratio 
so each side is
and the area is
Answer: 144
We have to set up 2 equations:
A) x + y = 10 liters
B) .05x + .25y = 10 * .10
Multiply equation B) by -4
B) -.2x - y = -4 then add to equation A)
A) x + y = 10 liters
.8x = 6 liters
x = 7.5 liters of 5%
y = 2.5 liters of 25%
They will have the same solution because the first equation of system b
is obtained by adding the first equation of system a to 4 times the
second equation of system a.
Answer: bigger number is 48 and smaller number is 36
Step-by-step explanation:
Answer:
24
Step-by-step explanation:
You need to plug in 3 for all of the x-values
That looks like 2(3)^2 + 5(3) - 9
Then if you simplify it is 2(9) + 15 - 9
Then simplify one last time and you get a final answer of 24
