Answer:
The expected number of wins for the player is 2.31
Step-by-step explanation:
No. of face cards = 12
total cards = 52
Probability of getting face card = 
Probability of getting face card = 
The player plays 10 times
Formula : 
n = no. of trials = 10
p = probability of success= 
E=expected number of wins


So, the expected number of wins for the player is 2.31
Well if you had 10 pencils and you added 1 more pencil it would be 11
The fourth and first one. :)
Answer:
P = 180 inches
A = 1800 square inches
Step-by-step explanation:
The perimeter of a rectangle is equal to P = 2b+2h where b=base and h=height. Here the base is 5 feet and the height is 30 inches. They are different measurements and must be in the same. Convert 5 ft into inches by multiplying 5*12 = 60 inches. Substitute b=60 and h=30.
P = 2*60 + 2*30
P = 120 + 60
P = 180 inches
The area of a rectangle is A = b*h. Substitute b=60 and h=30.
A= 60*30
A = 1800 square inches
Its decreased by 200 in the 4 years from 1994 to 1998 That is 50 less per year
In 1990 the population would have been 2500
So the required formula is
P = -50t + 2500 ( or you could write it as P = 2500 - 50t
