Answer:
C. 15/62
Step-by-step explanation:
The probability of drawing a boy's name first is 12/32. Then the probability of drawing a girl's name is 20/31, assuming the boy's name was not replaced. The joint probabiilty is the product of these:
... (12/32)·(20/31) = (3·4·5·4)/(16·2·31) = 15/62
The formula for finding the volume of a cube is base times width times height
3cmx3cmx3cm=27CM
Answer:
3(a + 5b + 7c) and 2x(2 + 5y + 11z)

Answer:
-0.8 and -8.2
Step-by-step explanation:
To solve a quadratic you first need to have one side of the equation equal to zero (because x-intercepts are when y is zero).
4x^2 + 24x + 13 = 2x^2 + 6x
2x^2 + 18x + 13 = 0
Then you can use the quadratic formula to solve for x. You will then come to
-18 ± sqrt(220) / 4
This will simplify out (rounding to the nearest tenth) to -0.8 and -8.2
