A bag contains 10 blue, 6 green, and 4 red marbles. You choose a marble with one hand and then a second marble with the other ha

Sergeu [11.5K]

Answer:

6/95.

Step-by-step explanation:

Prob(red marble on the first choice) = 4/(10+6+4)

= 4/20

= 1/5.

Prob(green marble on the second draw) = 6/19.

Prob( read then a green)

= 1/5 * 6/19

= 6/95.

(1 point) For the equation given below, evaluate ′ at the point (−1,2). (5−)^4+4^3=2433. ′ at (−1,2) =

ryzh [129]

Answer:

$\dfrac{343}{71}$

Step-by-step explanation:

Given the equation

$(5x-y)^4+4y^3=2433$

Find the derivative:

$((5x-y)^4+4y^3)'=(2433)'\\ \\4(5x-y)^3\cdot (5x-y)'+4\cdot 3y^2\cdot y'=0\\ \\4(5x-y)^3\cdot (5-y')+12y^2y'=0$

Substitute

$x=-1\\ \\y=2,$

then

$4(5\cdot (-1)-2)^3\cdot (5-y')+12\cdot 2^2\cdot y'=0\\ \\4(-5-2)^3(5-y')+48y'=0\\ \\4\cdot (-7)^3\cdot (5-y')+48y'=0\\ \\-1,372(5-y')+48y'=0\\ \\-6,860+1,372y'+48y'=0\\ \\1,420y'=6,860\\ \\y'=\dfrac{6,860}{1,420}=\dfrac{686}{142}=\dfrac{343}{71}$

How do I make 3.0035 into a fraction?

olga55 [171]

Make 3.0035 into a proportion, or over 1000000, to make it a whole number. 30035/1000000.

Factor the equation.

goblinko [34]

Answer:

$(5t+3), (t+3), (t-3)$

Step-by-step explanation:

Reorder terms.

$5t^3+3t^2-45t-27$

Factor out the greatest common factor from each group

$t^2(5t+3)-9(5t+3)$

Factor the polynomial by factoring out the greatest common factor, $5t +3$

$(5t+3)(t^2-9)$

Factor.

$(5t+3), (t+3), (t-3)$

hope this helps :)
