Step-by-step explanation:

Two dice with #s 1-6

To roll a sum of 7, the 2 numbers have to add up to 7.

First die                Second die

1                              6

2                              5

3                              4

4                               3

5                               2

6                               1

Each of those combinations adds up to 7. There are 6 of them. The total number of possibilities of rolls is 6 x 6 = 36.

Probability is favorable outcomes / total outcomes, so it's 6/36 = 1/6

PLEASE SOMEONE TELL ME HOW THEY GOT 423 cm AS THE ANSWER FOR A. I NEED HELP WITH THIS QUESTION!!!!!!!!!!!!!
3241004551 [841]

From the setup of the problem, the "length of the top of the bookcase, measured along the attic ceiling" will be the hypotenuse of a right triangle, the length "AB". We have both the angle between AB and AC and the length of AC (3.24 meters), so we can use trigonometric identities.

The cosine of the 40 degree angle between AB and AC is equivalent to the length of AC divided by the length of AB. Equivalently, we have:

cos(40) = \frac{3.24}{h}

where "h", the hypotenuse, is the length we want. Rearranging the formula to solve for h we have that

$h = \frac{3.24}{cos(40)}$

which is 4.2295... meters. Converting to centimeters (multiplying by 100) we have that h = 422.95... centimeters, or if we round the value, h = 423 centimeters.
