(Find the expected value of the winnings from a game that has the following payout probability)
I have all the answers with work shown and how to solve on the second image
Hope this help you guys :)
Answer:
The expected value is $2.1
Step-by-step explanation:
If we have an event with some given outcomes:
x₁, x₂, ..., xₙ
Such that each one of these outcomes has the correspondent probability:
p₁, p₂, ..., pₙ
The expected value is:
EV = p₁*x₁ + ... + pₙ*xₙ
In this case we have a table with the events (the payouts) and the probability for each one, so we have:
x₁ = $0
p₁ = 0.5
x₂ = $2
p₂ = 0.2
x₃ = $4
p₃ = 0.15
x₄ = $6
p₄ = 0.1
x₅ = $10
p₅ = 0.05
Now we can just replace these in the expected value equation, so we get:
EV = $0*0.5 + $2*0.2 + $4*0.15 + $6*0.1 + $10*0.05 = $2.1

John has $4,069 in an account. The interest rate is 12% compounded annually. To the nearest cent, how much interest will he earn in 1 year? Use the formula B=p(1+r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years. $
After solving the equation: the nearest cent, the interest earned is $467.
What is interest?Interest is a mathematical concept used to describe the cost or gain associated with the use of money over a period of time. It is usually expressed as a percentage rate of the principal (the amount borrowed or invested). Interest can be earned or paid, depending on the situation.
Using the formula B=p(1+r)t, John's final balance after 1 year is B = 4069(1+0.12)1 = $4,536.28.
The interest earned in 1 year is the difference between the final balance and the starting amount, which is $4,536.28 - $4,069 = $467.28. To the nearest cent, the interest earned is $467.

Calculate the perimeter of the parallelogram. Round to the nearest tenth, if necessary. Enter the perimeter, in units, using numbers only (decimal point is ok, if needed).
Answer:
28 units
Step-by-step explanation:
Firstly, we can see that the vertical sides are 9 units each.
To get the diagonal sides, we can turn the ends into right triangles, which we can then use with the Pythagorean Theorum.
To make the top side into a triangle, we would draw a horizontal line connecting points (-1, 3) and (3, 3). This creates a right angle which is essential when using the Pythagorean Theorum.
A^2 + B^2 = C^2
We can plug in values for the Pythagorean Theorum because we can see that going across horizontally from point (-1, 3) to (3, 3), there are 4 units in between the two points. This will be our A value. We will do the same but vertically from points (3, 6) to (3, 3). The 3 units between the two points will be our B value. Now, we can plug in our values into the Pythagorean Theorum to find side C, the hypotenuse.
4^2 + 3^2 = C^2
16 + 9 = C^2
25 = C^2
√25 = C
C = 5
Now that we know the diagonal value of the side, we also know the same diagonal value of the bottom side. When you add all four sides together,
9 + 5 + 9 + 5 = 28
you get 28, which is the perimeter of the parallelogram.

The right triangle represents a sketch of a wheelchair ramp that meets safety requirements. What is the horizontal distance required for the ramp? Round your answer the nearest tenth
The horizontal distance required for the ramp is 143.5 inches
Consider the following figure.
In right triangle ACB, CB is the horizontal distance,
hypotenuse AB = 144 in.
and the vertical distance AC = 12 in.
We need to find the measure of side CB
Let m be the measure of the horizontal distance CB
Using Pythagoras theorem for right triangle ACB,
(AB)² = (AC)² + (CB)²
Substitute given values in above equation.
(144)² = (12)² + (m)²
20736 = 144 + m^2
20736 - 144 = 144 + m^2 - 144
20592 = m^2
m^2 = 20592
m = 143.5 in.
Therefore, the horizontal distance is 143.5 in.

Two similar cones have volumes of 3970cm3 and 3100 cm3 respectively.
The height of the larger cone is 25cm.
Calculate the height of the smaller cone.
Answer:
The height of the smaller cone is 19.52 cm
Step-by-step explanation:
Given that,
The volume of cone 1, V₁ = 3970 cm³
The volume of cone 2, V₂ = 3100 cm³
The height of the larger cone, h₁ = 25 cm
We need to find the height of the smaller cone. Let it is h₂. For similar cones,
[tex]\dfrac{V_1}{V_2}=\dfrac{h_1}{h_2}[/tex]
Put values,
[tex]h_2=\dfrac{h_1V_2}{V_1}\\\\h_2=\dfrac{25\times 3100}{3970}\\h_2=19.52\ cm[/tex]
So, the height of the smaller cone is 19.52 cm.

Write them as ordered pairs in the form (x-coordinate, y-coordinate). Starting from the origin, explain how to plot the three equivalent ratios on a coordinate grid. (10 points)
9514 1404 393
Answer:
(1, 4)(2, 8)(3, 12)Step-by-step explanation:
The ratios all have ...
first number : second number = 1 : 4
Using first numbers of 1, 2, 3, the second numbers can be found by multiplying these by 4. (1, 4), (2, 8), (3, 12)
__
You plot these (x, y) points the same way you plot any point on a coordinate grid. The first (x) value is the horizontal distance from the vertical axis. Positive is to the right. The second (y) value is the vertical distance from the horizontal axis. Positive is up.
__
Of course, the origin is where the horizontal and vertical axes meet. It can be convenient to find one of the coordinates on its respective axis, then use the other coordinate to find the point at the desired distance from that axis.
Usually, you would choose the axis on the basis of how easy it is to determine exactly where the coordinate lies. If the y-axis is marked every 5, for example, it might be hard to determine where a multiple of 4 will lie. Locating the x-coordinate on the x-axis may be an easier way to start.
5( x-3 ) + 2x =41
What is x?
Answer:
8
Step-by-step explanation:
5 ( x - 3 ) + 2x = 41
5x - 15 + 2x = 41
5x + 2x - 15 = 41
7x - 15 = 41
7x = 41 + 15
7x = 56
x = 56 / 7
x = 8
Answer:
X=8
Step-by-step explanation:
Combine like terms: 5x + 2x = 7x
-15 + 7x = 41
Solving
-15 + 7x = 41
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '15' to each side of the equation.
-15 + 15 + 7x = 41 + 15
Combine like terms: -15 + 15 = 0
0 + 7x = 41 + 15
7x = 41 + 15
Combine like terms: 41 + 15 = 56
7x = 56
Divide each side by '7'.
x = 8

Answer:
a = 1.5
VW = 9 ft
Step-by-step explanation:
Since the tangent lines connect both circles, we know that the line VU and VX are congruent (equal). Thus, we can set them equal to each other and solve for a:
a + 4 = a² + 0.25 Set equal
a² - a = 3.75 Isolate a values
a² - a + 0.25 = 3.75 + 0.25 Complete the square
(a + 0.5)² = 4 Factor
a + 0.5 = 2 Simplify
a = 1.5
Now we need to calculate VW, but thats easy because its equal to TV, and since we know a, we can just plug it in:
((1.5) + 7.5) ft

Which statement regarding the region of rejection for a 5%
significance level is TRUE?
A z-score higher than 2 is part of the region of rejection
The region of rejection lies between the z-scores -2 and
2.
If a z-score falls within the region of rejection, it indicates
that the alternative hypothesis may be valid.
The region of rejection indicates that the null hypothesis
is true.
The statement regarding the region of rejection for a 5% significance level would be true is the region of rejection lies between the z-scores -2 and 2.Option B is correct.
What is region of rejection?A collection of values for the test statistic for which the null hypothesis is rejected constitutes a critical zone, sometimes referred to as the region of rejection. For example, if the observed test statistic is in the critical range, the null hypothesis is rejected and the alternative hypothesis is accepted.
Further the rejection zone is the area in which we have sufficient data to reject the null hypothesis if our test statistic falls within it. The rejection area, for the right-tailed test, for instance, is any value bigger than the critical value, or c 1 .
Therefore, the interval that causes the null hypothesis H 0 to be rejected in a hypothesis test is known as the region of rejection and is measured in the sampling distribution of the statistic under examination.
