Answer:
1.67
Step-by-step explanation:
you should do 15 ÷ 9 and you get 1.6666666667 and when you simplify that you get 1.67
Since ∠1 and ∠2 are complementary...they add up to be 90°.
∠1 = (-2x + 54)
∠2 = (8x + 18) we add these two up
6x + 72 = 90 subtract 72 from both sides
6x = 18
x = 3 place the value of x into the ∠2 equation
(8x + 18) = 8(3) + 18 = 24 + 18 = ∠2 = 42°

Step-by-step explanation:
The two rolls of the number cube are independent events because
the result of 1 roll does not affect the result of the other roll.
To find the probability of two independent events, we first find
the probability of each event, then we multiply the probabilities.
We can find the probability of an event using the following ratio:
number of favorable outcomes/total number of outcomes
Since there is only one way to roll a 3 and there are six
possible outcomes, 1, 2, 3, 4, 5, and 6, the probability of rolling a 3 is 1/6.
Since there is also only one way to roll a 2 and there are
six possible outcomes, the probability of rolling a 2 would be 1/6.
Now we multiply the probabilities.
1/6 x 1/6 is 1/36.
So the probability of rolling a 3 and a 2 is 1/36.
