Answer:
The expected value is -$0.17
Since it gives a negative expected value, the game is not favorable and should not be played
Step-by-step explanation:
Here, we want to calculate the expected game value and decide if the game is worth playing
Probability of rolling a six is 1/6
Probability of rolling a 5 is 1/6
Probability of rolling a number less than 5 is 4/6 = 2/3
So the only way to win is rolling a six
The expected value is thus;
1/6(3) - 0(1/6) - 2/3(1)
= 1/2 - 2/3
= -$0.17
Since the game gives a negative expected value, it is not favorable and should not be played
Hey!
What this question wants you to do is use PEDMAS, that is the order of operations, to get the answer.
P - Parentheses
E - Exponents
D - Division
M - Multipliation
A - Addition
S - Subtraction
So using PEDMAS, solve this problem by doing the operations first that come first, so you might want to start by solving 16 divided 2. (Division comes before multipliciation)
25
-13
which equals 12
This is because the circles have areas of 9
and 4
respectively.
Plus we can tell the square has the area of 100 due to the fact that the diameters of the circles add up to 10, meaning the larger circle has a radius equal to 5 and an area of 25
. Subtract the other two from the larger one and you get your answer.
Answer:
1
Step-by-step explanation:
(((a/b)^(-4))^0)=
((b/a)^4)^0)=
((b^4)/(a^4))^0=
1
(ANYTHING to the power of 0 is equal to 1)
Answer:
y=6x
Step-by-step explanation:
1. find the slope m. Pick two points on the line, such as (0,0) and (1,6). Plug those points into the slope formula.
m=change in y/change in x
m=6-0/1-0 Plug in (0,0)(1,6)
m=6/1 simplify
m=6
The slope is 6
2. Find the y-intercept. Since the line crosses the y-axis at 0, the y-intercept is 0.
3. Use the slope m=6 and the y-intercept b=0 to write the equation in slope-intercept form.
y=mx+b
y=6x+0 Plug in m=6 and b=0
y=6x
