57 % of which are french. every time he picks a card, he sticks it back in the deck and shuffles again. if seth picks a study card from the deck 4 times during her first study session, what is the probability that exactly 2 cards have a french word?

d 600 because 15*10*2=300

300+300=600

step-by-step explanation:

agree

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12
