Answer:
-$0.90
Step-by-step explanation:
There are only two possible outcomes, winning $23 (W) or losing $15 (L). Therefore:

The probability of the player making his next 3 free throws (P(W)) is:

The probability of the player NOT making his next 3 free throws (P(L)) is:

Expected value (EV) is given by the payoff of each outcome multiplied by its probability:

The expected value of the proposition is -$0.90
Answer:

12-2√4*√5
12-2*2√5
12-4√5
Answer:
B is correct.
Step-by-step explanation:
Quadratic Expression (Standard Form) is:

To say it simply, the expression must have 2 as the highest degree.
This means that if there are any higher or lower degrees than 2 then they are not quadratic expression.
A choice is not quadratic expression because it has 1 as the highest degree.
B choice is correct because 2 is the highest degree.
C choice is wrong because 3 is the highest degree.
D choice is wrong because it is not a polynomial.
Therefore, B is correct.
Answer:
Sam worked
hours that day (fractional answer)
Step-by-step explanation:
The total number of hours Sam worked is the sum of all the three hours given.
Let's add the first 2 using LCM and then add that result with the last.
Firstly:

Now,

The hours worked by Sam is 41/30 hours (fractional answer).
