Hello.

First, let's calculate

\(\tt{\displaystyle(\frac{7}{3}) ^{-3}\)

Remember the Properties of Exponents:

If we have a number to a negative power, we flop the number over:

\(\tt{a^{-b}=\displaystyle\frac{1}{a^b}\)

Now, let's use this property to simplify our expression.

Flop the number over:

\(\tt{\displaystyle(\frac{3}{7} )^3\)

Now, we should recall another property of exponents:

\(\tt{\displaystyle(\frac{a}{b} )^m=\frac{a^m}{b^m}\)

Since we have a fraction to a power, we should raise both the numerator and the denominator to the power:

\(\tt{\displaystyle\frac{3^3}{7^3}\)

3 cubed is 9, and 7 cubed is 343:

\(\tt{\displaystyle\frac{9}{343}\)

Now, the multiplicative inverse of that number is simply that number flopped over:

\(\Large\boxed{\tt{\displaystyle\frac{343}{9} }}\)

I hope it helps.

Have a great day.

\(\boxed{imperturbability}\)

Hi there! I am EnjoyingLife, and I hope you find my answer helpful! :)

STEPS:

First we have a negative power so we flop the number over

Then since we have a fraction to a power we raise both the top & bottom to that power.

Then, we flop the number over once more to find the multiplicative inverse.

The potential third side lengths that could form a triangle lies in the range 9<x<81.

Given that, two sides lengths are 36 inches and 45 inches.

The triangle inequality theorem describes the relationship between the three sides of a triangle. According to this theorem, for any triangle, the sum of lengths of two sides is always greater than the third side.

Here, the potential third side lengths that could form a triangle.

So, the range of third side lengths(x) is 45-36<x<45+36

⇒ 9<x<81

Therefore, the potential third side lengths that could form a triangle lies in the range 9<x<81.

The maximum price Matthew can pay for the car, considering his repayment capability and the loan terms, is approximately $126,318.29.

To determine the maximum price Matthew can pay for the car, we need to consider his repayment capability and the terms of the loan.

Matthew can make annual repayments of $35,000. Since the loan term is six years, the total amount he can repay over the loan period is $35,000 multiplied by six, which equals $210,000.

To calculate the maximum price of the car, we need to account for the interest rate of 9.25%. The interest rate represents the cost of borrowing and is applied to the loan amount.

Let's assume the loan amount is denoted by P.

The formula to calculate the future value of a loan with interest is:

FV = P(1 + r)^n

Where:

FV = Future value (total amount repaid)

P = Principal amount (maximum price of the car)

r = Interest rate per period (9.25% or 0.0925)

n = Number of periods (six years)

Since Matthew can repay a total of $210,000 over the loan period, we can set up the equation:

$210,000 = P(1 + 0.0925)^6

Now we can solve for P:

P = $210,000 / (1 + 0.0925)^6

Evaluating this expression, we find:

P ≈ $126,318.29

Therefore, the maximum price Matthew can pay for the car, considering his repayment capability and the loan terms, is approximately $126,318.29.

The solution to the equation is x = 17/30.

To solve the equation, start by combining like terms on both sides.

On the left side, we have the fraction 2/3 and the term -4x.

On the right side, we have the fraction 7/2 and the term -9x.

To combine the fractions, we need a common denominator.

The least common multiple of 3 and 2 is 6.

So, we can rewrite 2/3 as 4/6 and 7/2 as 21/6.

Now, the equation becomes:

4/6 - 4x = 21/6 - 9x

Next, let's get rid of the fractions by multiplying both sides of the equation by 6:

6 * (4/6 - 4x) = 6 * (21/6 - 9x)

This simplifies to:

4 - 24x = 21 - 54x

Now, we can combine the x terms on one side and the constant terms on the other side.

Adding 24x to both sides gives:

4 + 24x - 24x = 21 - 54x + 24x

This simplifies to:

4 = 21 - 30x

Next, subtract 21 from both sides:

4 - 21 = 21 - 30x - 21

This simplifies to:

-17 = -30x

Finally, divide both sides by -30 to solve for x:

-17 / -30 = -30x / -30

This simplifies to:

x = 17/30

So the solution to the equation is x = 17/30.

When one set of numbers in a measurement goes up as another set of numbers goes down, the two sets of numbers exist in an inverse relationship.

An inverse relationship occurs when there is a consistent pattern between two sets of numbers, where one set increases while the other decreases. This relationship can be observed in various scenarios and is often represented graphically as a downward-sloping line. In mathematics, this relationship is expressed using negative correlation coefficients or negative slopes. It implies that as one variable increases, the other variable decreases at a corresponding rate.

For example, consider the relationship between the price and demand for a product. As the price of a product increases, the demand for that product tends to decrease. This is known as the law of demand in economics. Similarly, in physics, the relationship between speed and time can exhibit an inverse relationship. As time decreases, speed tends to increase.

Overall, an inverse relationship between two sets of numbers indicates that they move in opposite directions. When one set of numbers increases, the other set decreases, and vice versa.

x - 4 = 6x + 16 or x - 4 = -6x - 16 for first equation

x - 4 = 6x + 16 export like terms to the same side of the equation

-4 - 16 = 6x - x (The terms chages signs from negative to positive and from positive to negative when exported to the other sideof the equation)

To find the number of days it will take for Juliana's investment to grow, we can use the formula for simple interest

I = P * r * t.

I = interest earned
P = principal amount (initial investment)
r = interest rate per year (in decimal form)
t = time in years In this case,

Juliana's principal amount (P) is $3,300, the interest rate (r) is 6.25% or 0.0625, and she wants to reach $3,450. We need to solve for t. $3,450 = $3,300 * 0.0625 * t Divide both sides of the equation by ($3,300 * 0.0625) to isolate t:
t = $3,450 / ($3,300 * 0.0625)
t = 17 So it will take Juliana approximately 17 days for her investment to grow to $3,450.

The probability of examining the five people till first patient has athlete's foot is given by (0. 84)^4(0. 16)^1.

Percent of people have athlete foot = 16%

Let us consider the probability of success represented by p = 0.16.

Using geometric distribution,

Probability of finding first patient with athlete's foot on kth examination is given by geometric probability distribution,

P(X = k) = (1 - p)^(k - 1) × p

where X is random variable representing number of trials needed until  first success.

Probability of finding the first patient with athlete's foot on the fifth examination k = 5,

⇒ P(X = 5) = (1 - p)^(5 - 1) × p

⇒ P(X = 5) = (0.84)^4 × 0.16

Simplify it we get,

⇒ P(X = 5) = 0.0473

Therefore, the probability of a podiatrist examining five people until he finds the first patient who has athlete's foot is (0. 84)^4(0. 16)^1.

The criterion used to obtain the ordinary least square (OLS) estimator is to minimize the sum of the squared differences between the observed values and the predicted values.

In OLS, the goal is to find the line that best fits the given data points. The estimator minimizes the sum of the squared residuals, which are the differences between the observed values and the predicted values. The squared residuals are used to ensure that both positive and negative differences contribute to the overall error measure.

The OLS estimator achieves this by calculating the coefficients of the linear regression model that minimize the sum of the squared residuals. It finds the intercept and slope of the line that minimizes the total squared distance between the data points and the regression line. This minimization process is based on the principle of least squares, which aims to find the best-fitting line by minimizing the overall error.

By minimizing the sum of the squared residuals, the OLS estimator provides a measure of how well the regression line represents the data points. It allows for the determination of the line's slope and intercept, which can be used for predicting values and understanding the relationship between the variables.

Answer:

F and G are both 112

Step-by-step explanation:

The 4 angles of a trapezoid add up to 360 degrees. Since you already have the two 68 degree angles, add them together to get 136/ Subtract this from 360 to get 224, then divide that by 2 to get the last two angles as 112 degrees each.

Answer: <F = 68˚, <G = 112˚, <H = 112˚

Since the trapezoid is isosceles,  <F = <J = 68˚, and <G = <H. To solve for the remaining angles, we note that the sum of all angles in a quadrilateral is 360˚, so <F + <J + <G + <H = 360˚. Plugging in <F = <J = 68˚, we have <G + <H = 360˚ - 2 × 68˚  = 224˚. Since <G = <H, they are both equal to 224/2 = 112˚.
