Answer:
5 : 3
Step-by-step explanation:
The odds in favor are ...
P(red) : P(not red) = (5/8) : (1 -5/8) = (5/8) : (3/8) = 5 : 3
_____
<em>Comment on the problem statement</em>
"equally sized slices" and "probability of red is 5/8" seem contradictory. Possibly we're missing a description that says there are 8 slices, of which 5 are colored red?
Divide 110 by 5 to get 22 or choice A.
You do this because at the end of the day he has 5 times more so we do the inverse to get the beginning or divide by 5.
a^2 + b^2 = c^2
In this case we're looking for C
so
(3)^2 + b^2 = (6)^2
9 + b^2 = 36
b^2 = 36-9
√b^2 = √27
b = 3√3
Answer: 5
Step-by-step explanation: f(3) = 2x - 1
substitute the x with 3. 2(3)-1
6-1
5
The number is x
it is negative
the square is 28 more than 3 times itself
x²=28+3x
minus (28+3x)
x²-3x-28=0
factor
(x-7)(x+4)=0
set to zero
x-7=0
x=7
this is not the answer because we were told the number was negative
x+4=0
x=-4
correct
the number is -4
test
(-4)²=28+3(-4)
16=28-12
16=16
check
the number is -4
