A spinner has 12 equal sectors with different letters for each sector Hamlet spins the spinner 5 times, and it stops at the letter "B" 4 times. If he spins the spinner a 10th time, what is the theoretical probability that this time it will stop at the letter 'B'?

Answers

Answer 1

Answer: The spinner has no memory. The probability of a 'B' is 1/12 or 8-1/3%. The first time, the 10th time, and the millionth time. No matter what has happened before.

Rewrite the expression -2a(a+b-5)+3(-5a+2b)+b(6a+b-8)

Answers

First, think of it as 3 different expressions.Go through them one at a time. There is:
-2a(a+b-5) ] +3(-5a+2b) ] +b(6a+b-8)
Multiply everything out.] Multiply everything out. ]Multiply everything out
-2a x a = -2a² ] +3 x -5a = -15a ] +b x 6a = 6ab
-2a x b = -2ab ] +3 x 2b = 6b ] +b x b = b²
-2a x -5 = 10a ] -15a + 2b = -15a+2b ] +b x -8 = -8b -2a² + -2ab + 10a = ] ] 6ab + b² + -8b =
-2a²+-2ab+10a ] ] 6ab+b²+-8b
Now add everything up, but before that, remember these algebraic rules:
∞A.S.S. Add Same Signs, meaning positive add positive or negative add negative equals a positive number or 0. E.g 1+1=1 and -1+-2= 1
∞S.I.D. Subtract If Different, meaning a positive number add a negative number always equals a negative number or 0. E.g 1 + -2 = -1
∞You can only add up "similar terms", meaning you can add 'terms' ending in 'a' for example with another 'term' ending in 'a'. However. you cannot add a term ending in 'a' to an 'ab' or an 'a²'.
Following these rules, -2a²+-2ab+10a+-15a+2b+6ab+b²+-8b =
4ab-5a-6b+b²-2a²

Hope that helps you and that it wasn't too tricky to understand. :)

What is greater .5 or .5%

Answers

When you see math printed or written, " % " means " /100 ".

So " .5% " means " .5/100 ".

If you simplify that, or write it as a decimal, you get 1/200 or 0.005 .

Either way, " .5 " is greater.

.5(0) is Fifty percent but .5% is less than 1%
