We must select a counter-example that makes the conclusion false.
3 is a prime, 5 is a prime, and 7 is a prime.
The conclusion is that all odd numbers are prime numbers.
A counter example is that 9 is an odd number but it is NOT a prime number.
Answer:
i believe its 11
Step-by-step explanation:
i counted the squares and the ones that are split in half im not 100 percent sure but pretty sure
The radius of the circle is given to be r = 14.5
Let the center be O. So OB is the radius = 14.5
We can draw a triangle as shown in the image below. We have a right angled triangle. We know the hypotenuse and the base, we need to find the perpendicular side. This can be done using the Pythagorean theorem.
So, we can write:

Thus, the measure of OA = 10.5
OB = OA + AB
14.5 = 10.5 + AB
⇒
AB = 4
This is false because 2(7)+0.8/0.2=56 and 22* -4 is equal to -88 and -88 is not equal to 56
A thumb-wrestling match requires two thumbs, so we can either suppose that we need at least two people

, or allow one to thumb-wrestle one's self. In either case, we'd have

, so let's just say we need a minimum of two players.
If we add one more person to the set of players, then the first two people would need to play 1 additional match each. So

.
If we add one more person, then the first three people would again each have to play 1 more match with the new person. So

.
And so on, so that in general, the number of games needed for everyone to play exactly one match with everyone else is given recursively by
