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?
13/7 * 49/2 * 4/49
13/7 * 1/2 * 4
13/7 * 2
26/7
Answer:
C
Step-by-step explanation:
Angle in a triangle add up to 180
since this is an isosceles triangle two angles are the same
180-(47+47)=86
Opposite angles are equal
Angles around a point add up to 360
360-(86+86)=188
188/2=94
94 degrees

Answer:
3 is the answer.
Step-by step explanation:
1/4 x 12
=> 1 x 3
=> 3
Therefore, 3 is the answer.
Hoped this helped.
<span>The question is asking us to find the complex number such that: ( 3 + 2 i ) * x = 17 + 7 i. We know that i^ 2 = - 1. x = ( 17 + 7 i ) / ( 3 + 2 i ) . We have to multiply the numerator and the denominator by ( 3 - 2 i ). Then: x = ( 17 + 7 i ) * ( 3 - 2 i ) / ( 9 - 4 i^2 ) = ( 51 - 34 i + 21 i - 14 i^2 ) / ( 9 + 4 ) = ( 51 + 14 - 13 i ) / 13 = ( 65 - 13 i ) / 13 = 65 / 13 - 13 i / 13 = 5 - i. Answer: The complex number is 5 - i. </span>
