Select all that apply. A card is randomly drawn from a deck of cards. (There are 52 cards in a deck, with 13 cards of each suit.

) You record the following results for the experiment. Hearts Clubs Spades Diamonds Times Drawn 28 32 18 22 Which of the following are true? The experimental probability of drawing a club is 32%. The theoretical probability of drawing a diamond is 25%. Based on the experimental probability, there would be 90 spades drawn in 500 trials. Based on the theoretical probability, there would be 120 hearts drawn in 500 trials.

True: The theoretical  probability of drawing a diamond is 25%. Since there are the same number of cards for each of the four suits, the chance of drawing any suit is 25%.

True: Based on the experimental probability, there would be 90 spades drawn in 500 trials. 0.18 x 500 = 90

The rest of the statements are false.

The correct answer would be 3(7+1) because 7+1=8 and 8 times 3 equals 24. 24 divided by six is 4 plus 20 would also be 24.

How much material is used
Neko [114]
This question is essentially asking you to find the surface area of the box.
The formula for SA on a rectangular prism is: 2(L*W+L*H+W*H)
L=Length W=Width H=Height

Lets input the information we know:
2(20*8+20*30+8*30)
Follow BEDMAS
2(160+600+240)
2(760+240)
2(1000)
2*1000
=2000

The box will need 2000 centimeters squared of material.

Hope this helps!

Answer:

x = 4 is the solution

Step-by-step explanation:

given  = x ( square both sides )

x + 12 = x² ( rearrange into standard form )

x² - x - 12 = 0 ← in standard form

(x - 4 )(x + 3 ) = 0 ← in factored form

equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x + 3 = 0 ⇒ x = - 3

Insert these values into the original equation, and if both sides are equal, and those are the solutions.

x = 4 :  =  = 4 = x ← correct

x = - 3 :  =  = 3 ≠ - 3 ← false

the answer is x = 4

A bag contains 4 red marbles, 6 blue marbles and 7 green marbles. If three marbles are drawn out of the bag, what is the probabi
yawa3891 [41]

Answer:

Step-by-step explanation:

Total marble = 4+6+7 = 17

Number of green = 7

Prob(1st green) = 7/17

Now their are 6 green left and 16 marble

Prob(2nd green) = 6/16 = 3/8

Now their are 5 green left and 15 marble

Prob(3rd green) = 5/15 = 1/3

Prob(1st and 2nd and 3rd green) will be = 7/17 × 3/8 × 1/3

= 7/(17×8)

= 7/136

The area of this rectangle is 3x2 what does the coefficient 3 mean in term of the problem
tangare [24]
By definition, the area of a rectangle is given by:
 A = (w) * (l)
 Where,
 w: width
 l: long
 For this case, we have that the area is given by:
 A = (3) * (2)
 Therefore, in terms of this problem, the coefficient 3 represents one of the dimensions of the rectangle.
 Answer:
 
The coefficient represents one of the dimensions of the rectangle.
