Hi there

Ok so here we have $7500 which needs to be decreased by 7%,

As it is decrease we need to reduce 7% of $7500 or in other words we need to subtract  whatever is 7% of $7500 from $7500

So we need 7% of $7500 first, so  lets find it,

7% of $7500 is: 7500* 7/100

⇒75 * 7/1 [Here we cancelled the zeroes from 7500 and 100]

⇒ 75 *7

⇒ 525

Now we need to subtract 525 from our 7500

⇒$7500-525

⇒$6975 is the required answer

I think you meant to write

(2 × 10⁶) × 0.00009

First, convert 0.00009 to scientific notation:

0.00009 = 9 × 10 ⁻⁵

Then

(2 × 10⁶) × 0.00009 = (2 × 10⁶) × (9 × 10 ⁻⁵)

… = (2 × 9) × (10⁶ × 10 ⁻⁵)

… = 18 × 10¹

… = 1.8 × 10²

The ending balance is $1032.5.

What is simple interest?

Simple interest is an interest rate that is solely calculated on the principal amount or the portion of the principal that is still owed. It does not take compounding into account. Simple interest may be used on a schedule other than annually, such as every month, week, or even every day.

Here, we have

Given: P = $2,500, r = 5.9%, t = 7 years

Convert 5.9% to a decimal

5.9% = 5.9 ÷ 100

 = 0.059

Substitute the values into the simple interest formula,

I = Prt   and we get

I = Prt

= 2500 × 0.059 × 7

= $1032.5

Hence, the ending balance is $1032.5.

Answer:

The First choice

Step-by-step explanation:

Prediction for some count is usually expressible as expectation of some random variable. The reasonable prediction for the number of times a white or red marble will be drawn is 54

A  random variable is usually taking some numerical information of each elementary event of the sample space . (map from sample space to real numbers). Its expected value is the best prediction value in most of the cases.

Binomial distributions consists of n independent Bernoulli trials.

Bernoulli trials are those trials which end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))

Suppose we have random variable X pertaining binomial distribution with parameters n and p, then it is written as

\(X \sim B(n,p)\)

The probability that out of n trials, there'd be x successes is given by

\(P(X =x) = \: ^nC_xp^x(1-p)^{n-x}\)

For the given case, as the ball being drawn is being replaced too, so we can take all 180 experiments to be independent from each other.

If we call

Success = Event of drawing white or  red marble

Failure = Event of drawing any other marble instead of white or red

Then, each marble drawing event is having two outcomes: success or failure. This makes each drawing a Bernoulli  experiment.

Modelling this situation with binomial distribution would be good.

Let X = number of successes in those 180 experiments.

Thus, we get

\(X \sim B(n = 180, p= 0.3)\)

The expectation of random variable X is the best prediction of count of times we will get in those 180 trials.

The expectation of a  random variable is: \(E(X) = np\)

Thus, we get:

\(E(X) = 180 \times 0.3 = 54\)

Thus, the reasonable prediction for the number of times a white or red marble will be drawn is 54

The volume of the Great Pyramid of Giza is approximately 2,583,283.3 cubic meters.

The Great Pyramid of Giza has a height of 146 meters and base sides of 230 meters. The formula for the volume of a pyramid is given as;

                    V = 1/3Ah

where V is the volume, A is the area of the base and h is the height of the pyramid.

Now, the Great Pyramid of Giza has a height of 146 meters and base sides of 230 meters. The area of its base can be calculated as follows:

Area, A = (1/2)bh

where b is the length of one side of the base and h is the height of the pyramid.

So, the area of the base is given by;

A = (1/2)(230)(230)A = 26,450 m²

Thus, the volume of the Great Pyramid of Giza is given by;

V = (1/3)(26,450)(146)

  = 2,583,283.3 cubic meters.

Therefore, the volume of the Great Pyramid of Giza is approximately 2,583,283.3 cubic meters.

The slope of the new road is zero.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

Take points from the Graph (5, 0) and (5, 4).

Slope of a line = m = tanθ

where θ is the angle made by the line with the x−axis.

For a line parallel to y−axis ,θ= π/2.

​

∴m = tan π/2 = undefined

The new road will therefore have 0° of inclination if it is perpendicular to D street because if they are perpendicular and D street is vertical, the new road is level and has 0° of inclination.

An horizontal line now has zero slope.

The equation for a multiple regression model with p predictor variables (x1, x2, ..., xp) and a response variable (y) can be written as:

y = β0 + β1*x1 + β2*x2 + ... + βp*xp + ε

In this equation:

- y represents the response variable (the variable we are trying to predict).

- β0 represents the y-intercept or the constant term.

- β1, β2, ..., βp represent the coefficients or weights associated with each predictor variable (x1, x2, ..., xp).

- x1, x2, ..., xp represent the predictor variables.

- ε represents the error term or residual, which accounts for unexplained variation in the model.

The multiple regression model aims to estimate the relationship between the predictor variables and the response variable by finding the best-fitting values for the coefficients β0, β1, β2, ..., βp.

The solution to the system of equations is (-10/3, 22/15) means there is only one unique solution.

The solution to the system of linear equations need to find the point the two lines intersect.

From the given information can see that one line passes through (-10, 4), (-5, 3) and (0, 2) the other line passes through (-8, 0), (-5, 3) and (0, 8).

The equations of the two lines using the slope-intercept form:

Line 1:

slope = (3-4)/(-5+10)

= -1/5

Using the point-slope form with the point (-5, 3), we get:

y - 3 = (-1/5)(x + 5)

Simplifying, we get:

y = (-1/5)x + 4

Line 2:

slope = (3-0)/(-5+8) = 1

Using the point-slope form with the point (-5, 3), we get:

y - 3 = 1(x + 5)

Simplifying, we get:

y = x + 8

Now, we can set the two equations equal to each other and solve for x:

(-1/5)x + 4 = x + 8

Multiplying both sides by 5, we get:

x + 20 = 5x + 40

Simplifying, we get:

6x = -20

x = -10/3

Substituting x = -10/3 into either equation, we can solve for y:

y = (-1/5)(-10/3) + 4 = 22/15

The solution set of a homogeneous system of 18 linear equations in 20 variables lies in the null space of the coefficient matrix.

To know that every associated nonhomogeneous equation has a solution, we need to ensure that the homogeneous system has a nontrivial solution.

This means that we need to know whether the rank of the coefficient matrix of the homogeneous system is less than the number of variables, i.e., whether there exist free variables.

If the rank is less than the number of variables, then there are infinitely many solutions to the homogeneous system, and thus every associated nonhomogeneous equation has a solution.

However,

We also need to ensure that the particular solution to the nonhomogeneous equation does not lie in the null space of the coefficient matrix.

This is equivalent to checking whether the null space of the coefficient matrix is orthogonal to the vector on the right-hand side of the nonhomogeneous equation.

If it is, then the nonhomogeneous equation has a solution.

So, in summary, to know that every associated nonhomogeneous equation has a solution.

In the original game, there are infinitely many Nash equilibria, as any pair of numbers chosen by the players where neither player can increase their payoff by unilaterally changing their choice is a Nash equilibrium.

However, the most commonly studied Nash equilibrium in this game is for both players to choose 0.
In the modified game, where one person choosing a number less than or equal to 10 and the other choosing a number greater than 10 results in both players receiving 0, there are two Nash equilibria: one where both players choose 0 and another where both players choose numbers greater than 10.
Explanation:
(a) In the original game, let's consider the case where both players choose the same number, let's say x. In this case, both players receive x dollars, and neither player can increase their payoff by changing their choice. Therefore, any pair of numbers where both players choose the same number is a Nash equilibrium.

(b) In the modified game, if one player chooses a number less than or equal to 10 and the other chooses a number greater than 10, both players receive 0. In this case, neither player can increase their payoff by unilaterally changing their choice, as both players will still receive 0. Therefore, the Nash equilibria in this game are pairs of numbers where both players choose 0 or pairs of numbers where both players choose numbers greater than 10.
Overall, the original game has infinitely many Nash equilibria, while the modified game has two Nash equilibria: one where both players choose 0 and another where both players choose numbers greater than 10.

The computed value of the test statistic is 2.94.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

We have a sample size of n = 12, engine size (x) and emissions (y) are the two variables being correlated, and the sample correlation coefficient is r = 0.47.

The null hypothesis is that the population correlation is zero (H0: ρ = 0) and the alternative hypothesis is that the population correlation is positive (Ha: ρ > 0).

To compute the test statistic, we need to first calculate the degrees of freedom (df), which is (n-2) = 10 in this case.

We can then use the formula for the test statistic, which is:

t = (r√(df)) / √1 - r²

Substituting the values we have, we get:

t = (0.47 √10) / √(1 - 0.47²)

t = 2.94

Absolute change is the numerical difference between two values and relative change is the proportional difference between two values expressed as a percentage.

Absolute change is the numerical difference between two values and is typically expressed as a positive number. It tells us the amount by which a value has increased or decreased.

For example, if the temperature increases from 20 degrees Celsius to 25 degrees Celsius, the absolute change in temperature is 5 degrees Celsius.

Relative change, on the other hand, is the proportional difference between two values and is typically expressed as a percentage. It tells us the amount by which a value has increased or decreased relative to its original value.

For example, if the price of a product increases from $10 to $15, the relative change in price is 50%, because the increase of $5 is 50% of the original price of $10.
