Answer:
it would be the Adjacent side (8) over the Hypotenuse, or the longest side which is 10. an easy way to remember this is CAH or Cosine=Adjacent/Hypotenuse
It is the fourth choice - 1/4.
There are five odd number out of the ten number they are choosing from.
The probability that Jason will choose an odd number is 5/10 = 1/2
The probability that Kyle will choose an odd number is 5/10 = 1/2
Multiply the two probabilities to get the probability of them choosing odd numbers.
1/2 * 1/2 = 1/4

Answer:
x = -7
Step-by-step explanation:
8x - 9 = 12 + 11x
Subtract 11x to both sides of the equation. Then, it will look like this:
-3x - 9 = 12
Add 9 to both sides of the equation. After that, it will look like this:
-3x = 21
Divide both sides of the eqution by -3. Your answer is:
x = -7
