There are ten balls in a bag. Three balls are black and seven balls are white. a One ball is chosen at random and then replaced.
pickupchik [31]

Answer:

Given:

  • Total balls = 10
  • Black balls = 3
  • White balls = 7

⇒ P(black ball) = 3/10 = 0.3

⇒ P(white ball) = 7/10 = 0.7

If one ball is chosen at random and <u>replaced</u>, the probabilities do not change between the first and second ball.

Let event D = first ball is black

Let event S = second ball is black

P(D) = 0.3

P(S) = 0.3  (since the first ball is replaced)

⇒ P(D ∩ S) = P(D) × P(S)

                   = 0.3 × 0.3

                   = 0.09

For Independent Events we know that:  P(A ∩ B) = P(A) × P(B)

Therefore, as P(D ∩ S) = P(D) × P(S) the events are independent.

Drum tight containers is designing an open-top, square-based, rectangular box that will have a volume of 62.5 in^3. what dimensi
Leno4ka [110]
Square means L=W
V=62.5=LWH

L=W so
V=62.5=HL^2
SA=2(L^2+2LH)

we have
V=62.5=HL^2
solve for H
divide both sides by L^2
62.5/L^2=H
sub that for H in other equation

SA=2(L^2+2L(62.5/L^2))
SA=2(L^2+125/L)
SA=2L^2+250/L
find minimum of 2L^2+250L^-1
take the derivitive
4L-250L^-2, or 2(2L^3-125)/L^2
find where it equals zero
it equals zero at L=2.5∛4
L=W
if we evaluate 2L^2+250/L at L=2.5∛4, the value is 75∛2

H=62.5/L^2
H=\frac{25 \sqrt[3]{2} }{4}



dimentions are
L=2.5∛4
W=2.5∛4
H=\frac{25 \sqrt[3]{2} }{4}
minimum surface area is 75∛2 in^2 or aprox 94.4941 in^2
