Answer:
0.75 ;
150
Step-by-step explanation:
Probability of rolling two even numbers :
{1, 2, 3, 4, 5, 6}
P(even) = 3 / 6 = 1/2
From a roll of 2 dice :
P(even) * P(even) = 1/2 * 1/2 = 1/4 = 0.25
P(not even) = 1 - 1/4 = 3/4
X : ____ 6 _______ - 1
P(x) ____ 0.25 ____ 0.75
Expected value :
Σx*p(x) = (6*0.25) + (-1 * 0.75)
= 1.50 - 0.75
= 0.75
If 200 games are played :, n = 200
Expected value * n
0.75 * 200
= 150
Answer:
b is -mx+y and m is -b+y/x
Step-by-step explanation:
Given:
quarterly deposits of 2,000
8 percent compounded quarterly ⇒ 2% per quarter
4 quarters in 15 years = 60 quarters
Future Value = (1 + r) x P [{(1+r)^n - 1} / r]
FV = (1 + 0.02) x 2,000 [{(1 + 0.02)⁶⁰ - 1} / 0.02]
FV = 232, 665.14 Choice B.
Each person will pay $7 before taxes and tip.
Step-by-step explanation:
Price of salad = $4
Price of two salads = 4*2 =$8
Price of sandwich = $6
As 4 friends ordered sandwiches, therefore,
Price of 4 sandwiches = 6*4 = $24
Price of slice of cake = $3
Total = 2 salads + 4 sandwiches + 1 slice of cake
5 friends will split the bill evenly, therefore,
Bill for one person = 
Bill for one person = 
Each person will pay $7 before taxes and tip.

Answer:
(1,0)
(-2,3)
(5,24)
Step-by-step explanation:
To solve this you can can just plug in the x and y values and see which work
y = x²-1
Lets test (0,1):
1 = 0²-1
1 = -1
This pair <em>does not</em> work, because 1 does not equal -1
Lets test (1,0):
0 = 1²-1
0 = 0
This <em>does</em> work, because 0 equals 0
Lets test (3,5):
5 = 3²-1
5 = 9 - 1
5 = 8
This pair <em>does not</em> work, because 5 does not equal 8
Lets test (5,24):
24 = 5²-1
24 = 25 -1
24 = 24
This pair <em>does</em> work, because 24 equals 24
Lets test (-2,3):
3 = (-2)²-1
3 = 4-1
3 = 3
This pair <em>does</em> work, because 3 equals 3
Lets test (-4,-17):
-17 = (-4)²-1
-17 = 16 - 1
-17 = 15
This pair <em>does not</em> work, because -17 does not equal 15
So the pairs that are on the graph are:
(1,0)
(-2,3)
(5,24)
