its pithagoreon so

c^2= a^2+ b^2

c^2= 32^2 +24^2

c^2= 1,024+576

c^2= 1600

c= $\sqrt{1600\\$ = 40

Suppose that two cards are randomly selected from a standard 52-card deck. (a) What is the probability that the first card is a

Roman55 [17]

Answer:

a. $\frac{1}{17}$

b. $\frac{1}{16}$

Step-by-step explanation:

We are given that two cards are drawn are randomly selected from a standard 52- cards deck.

Total cards=52

Total number of spade cards=13

Probability= $\frac{number\;of\;favourable\;cases}{total\;number\;of cases}$

a.The probability of drawing two cards first card is spade and second card is spade without replacement = $\frac{13}{52}\times \frac{12}{51}$

The probability of drawing two cards first card is spade and second card is spade= $\frac{1}{17}$

b. The probability of drawing two cards first is spade and second card is a spade with replacement = $\frac{13}{52}\times\frac{13}{52}$

The probability of drawing two cards first is spade and second card is a spade with replacement = $\frac{1}{16}$

Find the dimensions of the open rectangular box of maximum volume that can be made from a sheet of cardboard 41 in. by 22 in. by

BlackZzzverrR [31]

Answer:

V(max) = 1872.42 in³

Step-by-step explanation:

Let call " x " the side of the cut square in each corner, then the sides of rectangular base ( L and W )will be

L = 41 - 2*x and

W = 22 - 2*x x = the height of the open box

Volume of the box is

V(b) = L*W*x

And volume of the box as a function of x is:

V(x) = ( 41 - 2*x ) * ( 22 - 2*x ) * x

V(x) = ( 902 -82*x - 44*x + 4*x² ) * x ⇒ V(x) = ( 902 -126*x + 4x²) * x

V(x) = 902*x - 126*x² + 4x³

Taking derivatives on both sides of the equation we get:

V´(x) = 902 - 252*x + 12 *x²

V´(x) = 12*x² - 252*x + 902

V´(x) = 0 ⇒ 12*x² - 252*x + 902 = 0

A second degree equation solving for x (dividing by 2 )

6*x² - 126* x + 451 = 0

x₁,₂ = ( 126 ± √ 15876 - 10824 ) / 12

x₁,₂ = ( 126 ± 71,08 ) / 12

x₁ = 16 in ( we dismiss this value since 2x > than 22 there is not feasible solution for the problem)

x₂ = 54.92/12 ⇒ x₂ = 4,58 in

Then maximum volume is:

V(max) = 31.84 * 12.84 * 4,58

V(max) = 1872.42 in³
