Answer:
17 is a prime number
Step-by-step explanation:
A prime number has only two distinct factors. The number is itself a factor and 1 is the other factor.
An example is 17.
The factors of 17 are:
{1,17}
A composite number has more than two factors.
Therefore 17 is not a composite number.
It must however be noted that , 1 is not a prime number.
Answer:
(x - 9)(x + 9)
Step-by-step explanation:
x² - 81 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b), then
x² - 81
= x² - 9²
= (x - 9)(x + 9)
The probability that Olive flips heads and rolls an even number is 3/12 or 1/4.
These events are known as independent events which means the result of one event will not affect the other. The find the probability of the two events, you must multiply the probability of flipping heads and rolling an even number on a number cube.
1/2 x 3/6 = 3/12 OR 1/4 :)
I think the answer is X = 110°
