What is the value of x?

1 answer:

7 0

Since vertical angles are congruent, (4x+7)=5(x-4). So simplifying we get 4x+7=5x-20. If we add 20 on both sides we get 4x+27=5x. Now when we subtract x from both sides, we get x=27

Two diced are rolled. What is the probability that the sum of two numbers on the dice will be 4? 11/121/40

makkiz [27]

Each die has 6 possible outcomes (the numbers from 1 to 6).

If we roll two dices, the total number of outcomes is 6 * 6 = 36.

From these outcomes, the ones that have a sum of 4 are:

(1, 3), (2, 2) and (3, 1).

So, if we have 3 wanted outcomes from a total of 36, the probability is:

$P=\frac{3}{36}=\frac{1}{12}$

Therefore the correct option is the second one.
