You play a game where you roll a single die. You pay $1 to play, and the payouts are $0.50 if you roll an
even number, $2 if you roll a 1, and $1 if you roll a 3 or 5. What are the odds for winning money if you play this game? Show your work and Explain.
Answers
Let W be the random variable representing your winnings from playing the game. Then
\(P(W=w)=\begin{cases}\text{prob. of rolling an even number}=\frac12&\text{if }w=\$0.50-\$1=-\$0.50\\\text{prob. of rolling a 1}=\frac16&\text{if }w=\$2-\$1=\$1\\\text{prob. of rolling 3 or 5}=\frac13&\text{if }w=\$1-\$1=\$0\\0&\text{otherwise}\end{cases}\)
In short, you have a 1/6 chance of profiting from the game, and a 5/6 chance of losing money. So the odds of winning are (1/6)/(5/6) = 1/5 or 1 to 5.

Let's roll two dice and find the probability of rolling a certain sum. Is this a simple or compound event?
Two dice - Red and Blue
Recall that a simple event has one and only one outcome of interest. In this example, we are rolling two dice, but we are only interested in one outcome, the sum of the two dice. This is a simple event.
What is the probability of:
Rolling a sum of 1?
Rolling a sum of 3?
Rolling a sum of 12?
Rolling a sum of 7?
Since we are rolling a pair of dice and looking for the sum, the sample space is a little more complicated than rolling one die. The chart below will help us determine the possible outcomes. The top row indicates the numbers on the sides of the blue die and the first column represents the number on the sides of the red die. The white area indicates the sum of the numbers in the row and column.

Based on the circle graph how many pounds of milk and eggs does the average American consume each year PLS EXPLAIN FOR BRAINLEST
Answers
Answer:
Milk and Eggs = 552
Step-by-step explanation:
First add all of the other percentages together. (70%), 100%-70%=30%. 30% of 1840 = 552.
Answer:
H. 552
Step-by-step explanation:
Circle graph information:
Milk and eggs = x%Fruits and vegetables = 38%Cereals = 10%Meat and fish = 10%Sugar = 8%Fats and oils = 4%Total consumption = 1840 pounds per person
First, calculate the percentage of milk and eggs (the value of x).
Total percentages = 100%
⇒ x + 38 + 10 + 10 + 8 + 4 = 100
⇒ x + 70 = 100
⇒ x = 30
Therefore, 30% of food consumption is milk and eggs.
To calculate the number of pounds of milk and eggs the average American consumes each year, simply find 30% of the total consumption:
= 30% of 1840
= 30% × 1840
\(=\sf \dfrac{30}{100} \times 1840\)
= 552
Therefore, the average American consumes 552 pounds of milk and eggs each year.

The distance between the points (-6, 4) and (5, 4) is 11 units.
To find the distance between two points in a Cartesian coordinate system, we can use the distance formula:
Distance = √[(x2 - x1)² + (y2 - y1)²]
Given the two points (-6, 4) and (5, 4), we can plug in the coordinates into the distance formula:
Distance = √[(5 - (-6))² + (4 - 4)²]
= √[(5 + 6)² + 0²]
= √[11² + 0]
= √[121]
= 11
Therefore, the distance between the points (-6, 4) and (5, 4) is 11 units.
In this case, since the y-coordinates of both points are the same (4), the distance between them only considers the difference in their x-coordinates. As the x-coordinate of the second point is 11 units greater than the x-coordinate of the first point, the distance between them is simply the absolute value of the difference, which is 11.

Find the general solution of the given differential equation.
x dy/ dx − y = x^2 sin(x)
Also determine whether there are any transient terms in the general solution. (Enter the transient terms as a comma-separated list; if there are none, enter NONE.)
Answers
Answer:
\(y=-x\,cos\,x+Cx\)
There are no transient terms.
Step-by-step explanation:
Given: \(x\,\frac{dy}{dx} -y=x^2\,sin\,x\)
To find: general solution of the differential equation and the transient terms in the general solution.
Solution:
For an equation of the form \(\frac{dy}{dx}+yp(x)=q(x)\),
solution is given by \(ye^{\int {p(x)} \, dx }\) = ∫ q(x)\(e^{\int {p(x)} \, dx }\) dx
The given equation \(x\,\frac{dy}{dx} -y=x^2\,sin\,x\) can be written as \(\frac{dy}{dx}-\frac{y}{x}=x\,sin\,x\)
Here,
\(p(x)=\frac{-1}{x}\,,\,q(x)=x\,sin\,x\)
\(e^{\int{p(x)} \, dx } =e^{\int{\frac{-1}{x} } \, dx } =e^{-ln(x)} =e^{ln(x^{-1} )}=x^{-1}=\frac{1}{x}\)
So,
the solution is \(\frac{y}{x}=\int \frac{1}{x}x\,sin\,x\,dx\)
\(\frac{y}{x} =\int\,sin\,x\,dx\\\\\frac{y}{x} =-cos\,x+C\\y=-x\,cos\,x+Cx\)
Here, C is a constant.
Transient term is a term such that it tends to 0 as x → ∞
Here, there does not exist any term that tends to 0 as x → ∞
So, there are no transient terms.

Krystal throws a rappelling rope at a speed of 10 m/s down a 50 m cliff.
When will the rope hit the ground? Use the drop-down to put the correct order to solve for when the rope will hit the
ground.
Answers
With speed=10 m/s, the rope will hit ground after 3.36 seconds.
What exactly is speed?Speed is a measure of how fast an object is moving, usually measured in units of distance per unit time, such as meters per second (m/s) or kilometers per hour (km/h). It is a scalar quantity, meaning it only has magnitude and no direction.
Mathematically, speed is defined as the distance an object travels per unit time. The formula for calculating speed is:
Speed = Distance / Time
where Distance is the distance traveled by the object, and Time is the time taken to cover that distance.
here, we have,
Now,
To find when the rope will hit the ground, we can use the kinematic equation:
y = vi * t + (1/2) * a * t²
where:
y = 50 m (the height of the cliff)
vi = 10 m/s (the initial velocity of the rope)
a = 9.8 m/s² (the acceleration due to gravity, acting downward)
t = time it takes for the rope to hit the ground
We can solve for t by setting y=50 and solving for t:
50 = 10t + (1/2) * 9.8 * t²
50 = t(10 + 4.9t)
t = 50/14.9=3.36 s
Therefore, the rope will hit the ground after 3.36 seconds.

Roy used 1/4 of his money on 3 pens and 6 notebooks. The cost of each pen is 3 times the cost of each notebook. He bought some more pens with 2/3 of his remaining money. How many pens did Roy buy altogether?
Answers
=========================================================
Explanation:
Roy spends 1/4 of his money on 3 pens and 6 notebooks. That means 3/4 of it is leftover.
2/3 of 3/4 = (2/3)*(3/4) = 1/2 of his money is spent on buying some unknown number of additional pens. We'll come back to this later.
---------------
In terms of cost,
1 pen = 3 notebooks
which is another way of saying 1 pen is the same price as 3 notebooks.
Multiply both sides by 2 to get
2 pens = 6 notebooks
Therefore, saying "3 pens + 6 notebooks" is the same as "3 pens + 2 pens = 5 pens" when just thinking about costs.
---------------
In short, Roy buying 3 pens and 6 notebooks is the same as him buying 5 pens. He spends 1/4 = 25% of his money on getting these 5 pens.
Multiply those two values by 2 to find that 50% = 1/2 of his money would allow him to get 10 pens.
--------------
Recall that at the end of the first section, we concluded that Roy spent 1/2 of his money on buying those unknown additional number of pens. Then the previous section mentioned that 1/2 of his money gets him 10 pens. Therefore, he must have bought 10 additional pens on top of the original 3 mentioned in the instructions.
Overall, he purchased 3+10 = 13 pens
Answer:
13 pens
Step-by-step explanation:
If a pen costs 3 times the cost of a notebook, then the cost of 3 notebooks will equal the cost of a pen. The 6 notebooks that Roy bought are equivalent in cost to 2 pens, so 1/4 of Roy's money is the cost of 3+2 = 5 pens.
After the first purchase, Roy has (1 -1/4) = 3/4 of his money remaining. If he spends 2/3 of that on more pens, he will have spent ...
(2/3)(3/4) = 2/4
of his money on more pens. We've already seen that 1/4 of his money buys 5 pens, so 2/4 will buy 10 more pens.
Roy bought 3 +10 = 13 pens altogether.

Answers
The two equations that represent the situation are r+s= 1,787 and
4r+3s= 5,792. The solution is obtained using cost function.
What is Cost Function?
A mathematical formula known as a cost function is used to visualise how manufacturing costs will vary depending on the output level. In other words, given a specified quantity produced, it calculates the entire cost of production.
We are given that 'r' represent the number of reserve seats.
So, if 'r' number of reserve seats are sold, then '1,787-r' represents the number of student tickets sold.
Therefore, we get the equation as,
⇒ s= 1,787-r
⇒ r+s= 1,787
Also, we are given that tickets for a reserved seat, r, for the basketball game cost $4 each and student tickets, s, cost $3 each. Total $5,792 was earned in ticket sales.
Therefore, we get the equation as,
⇒ 4r+3s= 5,792
Hence, the two equations that represent the situation are r+s= 1,787 and
4r+3s= 5,792.

The numeric value of the exponential expression in this problem is given by the following option:
A. 2^12.
How to obtain the numeric value of the exponential expression?The exponential expression for this problem is defined as follows:
8^x/2^y.
8 is the third power of 2, hence:
8 = 2^3.
When a term is elevated to two of it's powers, the powers are multiplied, hence:
(2^3)^x = 2^(3x).
Meaning that the exponential expression is then written as follows:
8^x/2^y = 2^(3x)/2^y.
When two terms of the same base and different exponents are divided, we keep the base and subtract the exponents, hence the expression is given as follows:
2^(3x)/2^y = 2^(3x - y).
As stated in the problem, the numeric value of the expression 3x - y is given as follows:
3x - y = 12.
Hence the entire expression is simplified as follows:
2^(3x - y) = 2^12.
Meaning that the correct option is given by option A.

Answers
Answer:
∠ W = 53°
Step-by-step explanation:
the measure of the secant- secant angle W is half the difference of the measures of the intercepted arcs , that is
∠ W = \(\frac{1}{2}\) (YC - GT) = \(\frac{1}{2}\) (160 - 54)° = \(\frac{1}{2}\) × 106° = 53°
Suppose you are standing 19 feet from the base of a flagpole. You are able to determine that the angle of elevation to the top of the pole is 64.60 . Determine the height of the flagpole.
Answers
Answer:
40 ft
Step-by-step explanation:
Given that the angle of elevation is 64.6°, this means that the angle of depression from the top of the flagpole is 180 - 90 - 64.6, which is 25.4°
We can solve by using the sine rule, or the cosine rule.
Using the sine, we have
Sinθ = OPP/HYP, we're going to use the angle of depression, and thus
Sin 25.4° = 19/x, on rearranging, we have
x = 19/ sin 25.4°
x = 19/0.4289
x = 44.30 ft.
Now, we use Pythagoras theorem to get the height of the flagpole.
44.3² = 19² + y²
y² = 44.3² - 19²
y² = 1962.49 - 361
y² = 1601.49
y = √1601.49
y = 40 ft
