The probability of drawing a black marble from a bag is 1/2, and the probability of drawing a white marble from the same bag is

s344n2d4d5 [400]

<span>W = event where white marble is drawn
B = event where black marble is drawn

The two events W and B are independent. This is because the marble taken out on the first draw is put back into the bag. Since W and B are independent, we can use this rule

P(W and B) = P(w)*P(B)

Use the rule to get

P(W and B) = P(W)*P(B)
P(W and B) = (1/2)*(1/4)
P(W and B) = (1*1)/(2*4)

P(W and B) = 1/8

1/8 is equivalent to 0.125. Use long division or a calculator

0.125 = 12.5% </span>

Is 24 FL. Oz smaller or greater than 3 cups

user100 [1]

Take 24/8 to find out how may cups are in 24 ounces
so 24/8 = 3 cups

So it is equal to 3 cups not smaller nor greater

A line has a slope of -1/2 and a y-intercept of –2. What is the x-intercept of the line? –4, –1, 1 ,4

grin007 [14]

To get the x-intercept, we simply set y = 0 and solve for "x".

now, we have the slope and the y-intercept, well, let's plug those two in the slope-intercept form, reason why is called that anyway,

$\bf y=\stackrel{slope}{-\cfrac{1}{2}}x\stackrel{y-intercept}{-2}\implies 0=-\cfrac{x}{2}-2\implies \cfrac{x}{2}=-2\implies x=-4$
