An ordinary (fair) die is a cube with the numbers 1 through 6 on the sides (represented by painted spots). Imagine that such a die is rolled twice in succession and that the face values of the two rolls are added together. This sum is recorded as the outcome of a single trial of a random experiment.
Compute the probability of each of the following events.
Event A: The sum is greater than 6.
Event B: The sum is not divisible by 4.
Write your answers as fractions.

i need help with the volume, tsa and x please

Answers

Answer:

Volume = 42 units^2

x = 5 units

Total Surface Area = 96 units

Step-by-step explanation:

Volume

V = bh, where b = 1/2 * 3 * 4 and h = 7,

= 6 * 7 = 42 units^2

x

You can solve for this variable by using the pythagorean theorem;

a^2 + b^2 = c^2, where a = 3 and b = 4,

9 + 16 = x^2

= 25 = x^2

= x = 5 units

Total Surface Area

You can solve this by multiplying the perimeter of the base (3 + 4 + 5) by the height and adding that to two times the area of the base:

7 * (3 + 4 + 5) + 2(1/2*3*4)

= 7*12 + 12

= 96 units

Answer:

640 units squared

Step-by-step explanation:

First, the formula of a trapezoid is (a + b) x 2 divided by h

So, 40 + 24 = 64

64 x 20 = 1280

and 1280/2 = 640

what is the perimeter of 6 and 2

Answers

Answer:

In order to calculate perimeter, you need to add together the lengths of all four sides of the square. You are given the length of one side. Remember, all sides of a square are equal, so really you already have the measures of each side. Then, you add them together, so 6 + 6 + 6 + 6 = 24 inches.

Step-by-step explanation:

To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.

Answer:

Step-by-step explanation:

She walked 12 miles. Then she walked 1/4 that distance. "That distance" is 12 miles.

That means she walked 12 miles plus 1/4 of 12 miles.

She walked

12 + 1/4 * 12

You can factor out 12 from the expression above, and write it as

12(1 + 1/4)

Now you can do the addition in parentheses.

12(1 + 1/4) = 12(4/4 + 1/4) = 12(5/4)

Answer:

C, D, F

Answer:

12 + 1/4 x 12, 12 x 5/4, and 12 (1 + 1/4)

Step-by-step explanation:

To solve this, you need to add 1/4 of 12 to 12. 1/4 of 12 is 3, and 12 + 3 is 15. All of these equations are equal to 15, therefore they are all correct.

1/4 x 12 = 3 + 12 = 15

12 x 5/4 = 60/4 = 15

1 + 1/4 = 5/4

5/4 x 12 = 60/4 = 15
