Answer: 2</h3>
========================================================
Explanation:
If a number only has one factor pair, then that number must be prime. This is because prime numbers only have factors of 1 and the number itself.
For instance, the value 7 is prime because the only factors of this are 1 and 7.
For something like the number 32, it is composite and not prime because it has the factors {1,2,4,8,16,32} and it leads to these three factor pairs: 1*32, 2*16, 4*8. This is one example showing why the answer isn't composite.
-----------
Let's say that p is the unknown prime we want to find. The factors of this are 1 and p. We're told that "one of the factors is twice the other factor", so that must mean p = 2*1 = 2. We can see that 2 is twice that of 1.
Answer:
Since U is the midpoint of XY,
90.42857143 or
90.4 to nearest decimal
From the problem, the way the spinner is set up could be
red red blue blue green green yellow yellow purple purple
with two sections of each color and 10 total equal sections.
From this we know that 4 out of the 10 sections are red or green.
That means that there is a 4/10 chance of getting a green or a red every time Kevin spins.
Multiply 180 by 4/10 and you get 72.
The spinner will land on red or green about 72 times.
Hope this helps!
