Expected value of the bet is
the sum of the products of value of outcome and its probability,
less the amount paid to place the bet.
Outcomes value probability
win 225 1/4
lose 0 3/4
cost of bet = 40
So expected value of bet
E[X]=225*(1/4)+0*(3/4)-40
=56.25-40
=16.25
This means that in the long run, gambler will win, since the expected value is positive. (does NOT mean she will win in the next bet!)

Answer: n/5 - 10 = 18: this would be the equation. Your answer would be 140.
Step-by-step explanation: Let consider the number as ‘X’
Quotient of a number and 5 can be written as
X divided by 5
Ten subtracted from the quotient of a number and 5 can be written as
(X divided by 5)-10
Ten subtracted from the quotient of a number and 5 is 18 can be written as
(X divided by 5)-10=18
By solving the above equation, find ‘X’
(X divided by 5) = 18 + 10
X/5=28
X = 28 x 5 = 140
Answer:
y = 7°
Step-by-step explanation:
By interior angle sum theorem of a triangle.

7,134 + d = 10,000
Subtract 7,134 from each side:
d = 10,000 - 7,134
d = 2,866
