Answers

The value of the probability represented by P(Take the bus | Sophomore) is 0.83

What are conditional probabilities?

Conditional probabilities are probabilities that only occurred because an event has already occurred i.e. they are dependent on the initial event

How to determine the conditional probabilities?

From the table of values in the question, we have the following parameters:

Number of students that (Take the bus and Sophomore) = 25Number of students that are (Sophomore) = 2 + 25 + 3

The required probability represented by P(Take the bus | Sophomore ) = [?] is then calculated as:

P(Take the bus | Sophomore) = Number of students that (Take the bus and Sophomore) divided by Number of students that are (Sophomore)

Substitute the known values in the above equation

P(Take the bus | Sophomore) = 25/(2 + 25 + 3)

Evaluate the sum in the denominator

P(Take the bus | Sophomore) = 25/30

Evaluate the above quotient

P(Take the bus | Sophomore) = 0.83

Hence, the value of the probability represented by P(Take the bus | Sophomore) is 0.83

you go to a convenience store to buy candy and find the owner to be rather odd. he allows you to buy pieces in multiples of four, and to buy four, you need . he only allows you to do this by using pennies and dimes. you have a bunch of pennies and dimes, and instead of counting them, you decide to weigh them. you have g of pennies, and each penny weighs g. each dime weighs g. each piece of candy weighs g

Answers

To buy four pieces of candy from the odd owner, you need to have a specific number of pennies and dimes.

To buy candy from the odd owner, you need to use multiples of four. The problem states that each piece of candy weighs g, so to buy four pieces, you need g. The owner only accepts payment in pennies and dimes. Each penny weighs g, and each dime weighs g.

To figure out how many pennies and dimes you need to buy four pieces of candy, you can use the weight information. Since you have g of pennies, and each penny weighs g, you can calculate the number of pennies. This can be done by dividing the total weight of the pennies (g) by the weight of each penny (g). The result will give you the number of pennies you have.

Similarly, you have g of dimes, and each dime weighs g. By dividing the total weight of the dimes (g) by the weight of each dime (g), you can find the number of dimes you have.

Now, let's say the number of pennies you need to buy four pieces of candy is P, and the number of dimes you need is D. To find the values of P and D, you can set up an equation:

P * penny weight + D * dime weight = g.

This equation represents the total weight of the pennies and dimes you have.

Solving this equation will give you the values of P and D, which represent the number of pennies and dimes you need to buy four pieces of candy.

To buy four pieces of candy from the odd owner, you need to have a specific number of pennies and dimes. By using the weight information provided in the problem, you can calculate the number of pennies and dimes you have. You then set up an equation to determine the values of P and D, representing the number of pennies and dimes needed. Solving this equation will give you the required values, allowing you to conclude the number of pennies and dimes needed to buy four pieces of candy.

explain why the function defined by M(t) = 2t + 1 has no maximum value on the interval [0,4)

Answers

The function defined by M(t) = 2t + 1 has no maximum value on the interval [0,4) as the derivative of m(t) is not equal to zero.

The maxima of the function can be calculated by the derivative of the function. The derivative is equated to 0 to calculate the critical points. If the second derivative is negative at this critical point then a maximum exists at this point.

The function is M(t) = 2t + 1 . Differentiate the function with respect to t. Now equate the derivative to 0. This will give the critical point. Since 2 is not equal to 0, the critical point does not exist on the curve of the function. Therefore, the function M(t) = 2t + 1does not have a maxima. M(t) = 2t + 1

d/dt M(t) = d/dt 2t + 1

= 2

d/dt m'(t) = 0

2 not equal to 0

The function does not have a critical point. Therefore, the maxima do not exist for the function.

Find the value of k for which the following system of linear equations has no solutions: (k-1)x - y = 5 and (k + 1) + (1 - k)y = (3k + 1).

Answers

If k = 2/3, the two lines will be parallel and the system of linear equations will have no solutions.

What is linear equation?

An equation is a mathematical assertion in which the algebraic expression is separated by an equal symbol (=). Equations of degree 1 are linear equations. It is the straight line's equation. When values are replaced for the unknown values in linear equations' solutions, the equation is proved to be true. There is only one answer when there is only one variable.

We can solve this problem using the concept of parallel lines in the coordinate plane. If two lines are parallel, they will never intersect and therefore have no solutions in common.

To determine if the system of linear equations has no solutions, we need to check if the lines represented by the equations are parallel. To do this, we can rewrite the equations in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept:

(k-1)x - y = 5 --> y = (k-1)x - 5

(k + 1) + (1 - k)y = (3k + 1) --> y = (-k/2) + ((3k + 2)/2)

Comparing the slopes of the two lines, we can see that they are parallel when k - 1 = -k/2, since the slopes of the lines are k - 1 and -k/2, respectively.

Simplifying the equation k - 1 = -k/2, we get:

2k - 2 = -k

Adding k to both sides, we get:

3k - 2 = 0

Adding 2 to both sides, we get:

3k = 2

Dividing both sides by 3, we get:

k = 2/3

Therefore, if k = 2/3, the two lines will be parallel and the system of linear equations will have no solutions.

Answers

The given definite integral ∫ arccos(x)√(1-x²) dx over the interval [0, 1/2] is to be evaluated. To rewrite the integral in a known form, a creative strategy is used by completing the square.

To evaluate the given integral, we can rewrite it using a creative strategy called completing the square. We start by observing that the integrand involves the square root of a quadratic expression, which suggests completing the square.

First, let's focus on the expression inside the square root, 1 - x². We can rewrite it as (1 - x)² - x(1 - x). Expanding and simplifying, we have (1 - x)² - x + x² = 1 - 2x + x² - x + x² = 2x² - 3x + 1.

Now, the integral becomes ∫ arccos(x)√(2x² - 3x + 1) dx. By completing the square, we can rewrite the quadratic expression as √2(x - 1/4)² + 15/16. This simplification allows us to rewrite the integral in the form of a known formula, specifically the integral of arccos(x)√(1 - x²) dx. Therefore, the integral becomes ∫ arccos(x)√(1 - x²) dx, which is a standard form with a known solution. We can proceed to evaluate this integral using appropriate techniques.

is an acute triangle sometimes, always or never equilateral? if the answer is always or never explain how you know.

Answers

An acute triangle is never equilateral. The reason is that in an acute triangle, all three angles are less than 90 degrees. An equilateral triangle has three equal angles, each measuring 60 degrees. Since all angles of an acute triangle are less than 90 degrees, none of them can be equal to 60 degrees, which is necessary to form an equilateral triangle.

As a result, an acute triangle cannot be equilateral. An acute triangle is a triangle in which all three angles are acute, meaning that each angle is less than 90 degrees. On the other hand, an equilateral triangle is a triangle with three sides of equal length and three equal angles. Since all angles of an acute triangle are less than 90 degrees, none of them can be equal to 60 degrees, which is necessary to form an equilateral triangle.

Therefore, an acute triangle cannot be equilateral. In conclusion, an acute triangle can never be equilateral, because an equilateral triangle requires all three angles to measure 60 degrees, while all three angles of an acute triangle are less than 90 degrees.

For a recent paint job, Josh mixed red and white paint to make two different shades of pink. When the job was done, Josh ended up with leftover paint: 5 gallons of dark pink paint (80% red) and 4 gallons of light pink paint (30% red). Josh wants to make a medium pink color (50% red) to paint his daughter's bedroom. He will need 3 gallons to completely cover the walls. How much of each of the leftover paints should Josh mix to achieve his desired color?
? gallons of dark pink paint
? gallons of light pink paint

Answers

Josh should mix 1.2 gallons of dark pink paint and 1.8 gallons of light pink paint to achieve the desired medium pink color.

To find out how much of each leftover paint Josh should mix to achieve a medium pink color (50% red), we can set up a system of equations based on the percentages of red in the paints.

Let's assume that Josh needs x gallons of dark pink paint and y gallons of light pink paint to achieve the desired color.

The total amount of paint needed is 3 gallons, so we have the equation:

x + y = 3

The percentage of red in the dark pink paint is 80%, which means 80% of x gallons is red. Similarly, the percentage of red in the light pink paint is 30%, which means 30% of y gallons is red. Since Josh wants a 50% red mixture, we have the equation:

(80/100)x + (30/100)y = (50/100)(x + y)

Simplifying this equation, we get:

0.8x + 0.3y = 0.5(x + y)

Now, we can solve this system of equations to find the values of x and y.

Let's multiply both sides of the first equation by 0.3 to eliminate decimals:

0.3x + 0.3y = 0.3(3)

0.3x + 0.3y = 0.9

Now we can subtract the second equation from this equation:

(0.3x + 0.3y) - (0.8x + 0.3y) = 0.9 - 0.5(x + y)

-0.5x = 0.9 - 0.5x - 0.5y

Simplifying further, we have:

-0.5x = 0.9 - 0.5x - 0.5y

Now, rearrange the equation to isolate y:

0.5x - 0.5y = 0.9 - 0.5x

Next, divide through by -0.5:

x - y = -1.8 + x

Canceling out the x terms, we get:

-y = -1.8

Finally, solve for y:

y = 1.8

Substitute this value of y back into the first equation to solve for x:

x + 1.8 = 3

x = 3 - 1.8

x = 1.2

Therefore, Josh should mix 1.2 gallons of dark pink paint and 1.8 gallons of light pink paint to achieve the desired medium pink color.

Polya's four-step problem-solving strategy is as follows:

Step 1: Understand the problem.

We are given that a frog is at the bottom of a 19-foot well. Each time the frog leaps, it moves up 3 feet. If the frog has not reached the top of the well, it slides back 1 foot before it is ready to make another leap. We are asked to find out how many leaps the frog needs to escape the well.

Step 2: Devise a plan.

To solve this problem, we need to determine how many leaps the frog needs to reach the top of the well. We can use a table to keep track of the frog's progress. Each row of the table represents a leap, and each column represents the frog's position after each leap.

Step 3: Carry out the plan.

Table:

According to the table inserted above, the frog needs 10 leaps to escape the well.

Step 4: Evaluate the solution.

We can verify our answer by checking the last row of the table. After the 10th leap, the frog reaches a position of 21 feet, which is above the top of the well. Therefore, the frog has escaped the well in 10 leaps.

Therefore, the frog needs 10 leaps to escape the well.

The x-intercept of the line calculator is (-1,0) while the y-intercept is (0,-3).

To determine the x-intercept, let y = 0 and solve for x in the equation y = 3x - 1.

Substitute 0 for y in the equation.0 = 3x - 1

Add 1 to both sides1 = 3x

Divide both sides by 3x = 1/3

The x-intercept of the line is (1/3, 0).

To find the y-intercept, let x = 0 and solve for y in the equation y = 3x - 1.

Substitute 0 for x in the equation.y = 3(0) - 1y = -1

Answers

This indicates that after accounting for the inflation rate of 7%, the purchasing power of the $1,000 investment decreased by approximately 1.92%.

The real rate of return represents the rate of return adjusted for inflation, which reflects the purchasing power of the investment. To calculate the real rate of return, we subtract the inflation rate from the nominal interest rate.

In this case, the nominal rate of interest is 5 percent, but prices have actually risen by 7 percent, indicating an inflation rate of 7 percent. Therefore, the real rate of return can be calculated as follows:

Real rate of return = Nominal interest rate - Inflation rate

Real rate of return = 5% - 7%

Real rate of return = -2%

The negative sign indicates that the purchasing power of the investment has decreased. To express the real rate of return as a positive value, we take the absolute value, resulting in approximately 2%. Therefore, Gladys earned a real rate of return of approximately -2% or -1.92% (rounded to two decimal places).

Write an equation for a parabola with a vertex of (-2,1) and a focus of (-2,4)

Answers

Answer:

$y=\frac{1}{12}(x+2)^{2}+1$

Explanation:

Given a parabola with the following properties:

• Vertex: (-2, 1)

• Focus: (-2, 4)

We want to write an equation for the parabola.

The standard equation of an up-facing parabola with a vertex at (h,k) and a focal length |p| is given as:

$\begin{equation}(x-h)^{2}=4 p(y-k)\end{equation}$$\begin{gathered} Vertex,(h,k)=(-2,1)\implies h=-2,k=1 \\ Focus,(h,k+p)=(-2,4)\implies h=-2,k+p=4 \end{gathered}$

We solve for p:

$\begin{gathered} k+p=4 \\ 1+p=4 \\ p=4-1 \\ p=3 \end{gathered}$

Substitute the values h=-2, k=1, and p=3 into the standard form given earlier:

$\begin{gathered} (x-(-2))^2=4(3)(y-1) \\ (x+2)^2=12(y-1) \\ \text{ Divide both sides by 12} \\ \frac{1}{12}(x+2)^2=y-1 \\ \text{ Add 1 to both sides of the equation} \\ y=\frac{1}{12}(x+2)^2+1 \end{gathered}$

The equation for the parabola is:

$y=\frac{1}{12}(x+2)^{2}+1$

true or false: if a is a matrix with more columns than rows then the number of non-zero singular values of a is greater than the rank of a

Answers

The given statement is False.

The number of non-zero singular values of a matrix is equal to the rank of the matrix. The rank of a matrix is the number of non-zero singular values, or equivalently, the dimension of the space spanned by its columns. It is not related to the number of columns or rows in the matrix.

In general, the singular values of a matrix are a measure of the "size" or "magnitude" of the matrix and are defined as the square roots of the eigenvalues of the matrix A^T A (where A^T denotes the transpose of A). The rank of a matrix is the number of linearly independent columns or rows in the matrix. It is a measure of the "degrees of freedom" of the matrix and is equal to the number of non-zero singular values.

So to summarize, if a is a matrix with more columns than rows, it does not necessarily mean that the number of non-zero singular values of a is greater than the rank of a. The number of non-zero singular values and the rank of a matrix are both determined by the structure of the matrix itself and are not directly related to the number of columns or rows.
