Answer:
B
Step-by-step explanation:
Dilations are the only transformations in which the shape is changed.
Answer:
b
Step-by-step explanation:
divide both sides by 2pi
Answer:
b = -10
<M = 90
<N = 50
<O = 40
Step-by-step explanation:
The sum of the angles of a triangle add to 180
<M + <N + <O = 180
90 + -3b+20 + -3b +10 = 180
Combine like terms
120 -6b = 180
Subtract 120 from each side
120-120 -6b = 180-120
-6b = 60
Divide by -6
-6b/-6 = 60/-6
b = -10
<M = 90
<N = -3b +20 = -3(-10) +20 = 30+20 = 50
<O = -3b +10 = -3(-10)+10 = 30+10 = 40
I would use the theoretical method because each of the 52 cards is equally likely to be drawn.
There are 52 cards in a deck so there are 52 possible outcomes.
The event of interest is drawing a club or a diamond. There are 13 clubs and 13 diamonds. Add those up and that gives you 26 cards, which is the possible number of outcomes. knowing this we divide 26 by 52.
number of outcomes / total number of possible outcomes
26 / 52 = 1 / 2 = .5 = 50%
So the probability of this even is 1 out of 2 or you have a 50% chance of getting your club or diamond
