A bag contains red and blue marbles, such that the probability of drawing a blue marble is e. an experiment consists
marble, replacing it, and drawing another marble. The two draws are independent. A random variable assigns the num
marbles to each outcome.
What is the probability that the random variable has an outcome of 0?
a. ≈24%
c. ≈14%
b. ≈39%
d. 0

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

lol.

it's ok we all do this sometimes.

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%

a reflection across the x axis and a 90 degree rotation left and right.
