Answer:
Step-by-step explanation:
Probability of getting a 7 + Probability of not getting a 7 = 1.
Odds against drawing a 7 = Probability of not getting a 7.
We could calculate the probability of getting a 7 and subtract 1 from it to get the answer.
There a four sevens in a deck of card, one of each kind.
Probability of getting a 7 = 
P(not getting a 7) 
w=61, the equation is w=(456-a-b-c)/2, so the work would look like 456-132-94-108=122/2=61
Answer: 720.3
Step-by-step explanation:
First you divide 6.4 by 9.8 then you divide by 470.40 to get 720.3

Answer:
A=63.6 approximately
Step-by-step explanation:
P=14.28
p=1/4(2pi*r)
p=1/2pi*r
14.28=1/2pi*r
28.56=3.14*r
r=9...... approximately
A=1/4pi*r^2
A=0.25*3.14*81
A=63.6......approximately
Answer:
x = 16
Step-by-step explanation:
The two angles are vertical angles, which means they are equal
3x-3 = 2x+13
Subtract 2x from each side
3x-3-2x =2x-2x+13
x-3 =13
Add 3 to each side
x-3+3 =13+3
x = 16
