Answer:

slope = 2

Step-by-step explanation:

-8 - -6 / -9 - -8 = 2

Answer:

\(\frac{2}{1}\) which is just 2

Step-by-step explanation:

slope = \(\frac{y2 - y1}{x2 - x1}\)

So plug the numbers in, now it should look like \(\frac{-6 - (-8)}{-8 - (-9)}\)

-6 - (-8) = 2

-8 - (-9) = 1

So the slope is \(\frac{2}{1}\)

The, option (a) is the correct answer. Option (b) is incorrect since the higher interest rate in Japan would discourage investment in Canada, rather than attracting it. Option (c) is also incorrect since interest rate differentials are a significant driver of capital flows between countries. Option (d) is not directly related to the question of interest rate differentials and capital flows.

Capital will flow from Japan to Canada.

When interest rates are higher in one country compared to another country, investors will seek to invest in that country to earn higher returns. In this case, the interest rate is higher in Japan (7%) compared to Canada (4%), and financial assets in the two countries are equal in risk. As a result, investors in Japan will seek to invest in Canada to earn a higher return, which will result in the outflow of capital from Japan and the inflow of capital into Canada.

Suppose that the interest rate in Canada is 4%, in Japan it is 7%, and financial assets in the two countries are equal in risk. As a result, capital will flow from Canada to Japan. The correct option is (b).

To determine the direction of capital flow between countries based on interest rate differentials, we need to consider the concept of interest rate parity.

According to interest rate parity, capital tends to flow from a country with a lower interest rate to a country with a higher interest rate.

In this case, the interest rate in Canada is 4% while in Japan it is 7%. Since the interest rate in Japan is higher than in Canada, according to interest rate parity, capital is expected to flow from Canada to Japan.

It's important to note that this analysis assumes that other factors such as exchange rates, inflation, and market conditions remain constant.

In reality, capital flows can be influenced by a range of other factors, including market expectations, political stability, and economic outlook, which may complicate the relationship between interest rates and capital flows.

Therefore, the correct option is (b.) capital will flow from Canada to Japan.

Answer:

y = -2x + 2

Step-by-step explanation:

slope is found with (change in y/change in x), or in this case, (-4--2,3-2), which is -2

with the equation y = -2x + b, solve for b by plugging in the x and y values of one of the points

using (2, -2):

-2 = -2(2) +b

b = 2

so the equation is y = -2x + 2

Using the properties of similar triangles and ratio and proportion we get the vale of x as 2.8 units.

In the given figure the triangle ΔKFG and ΔFJH

KG is parallel to JH

Hence ΔKFG is similar to ΔFJH

Now using the property of similarity and proportion we can say that:

FG/FH = KF/JF

putting the values in the above proportion we get:

7 /(7+x) = 5/ 7

or, 49 = 35 +5 x

or, 14 = 5x

or, x =14/5

or, x = 2.8

The majority of ratio and percentage explanations involve using fractions.

A proportion states that two variables are equal, whereas a ratio is a fraction that is written as a:b. The two ratios given are equal to one another, as demonstrated by the proportional equation.

Hence the value of x is 2.8 units.

Dave bought more than 4 packs of trading cards.

Dave attended a game convention to purchase packs of trading cards, with each pack costing $5.

He exceeded his $20 budget in order to acquire all the cards he wanted. Let x represent the number of packs Dave bought.

Since each pack costs $5 and he went over his $20 budget, he must have bought more than 4 packs (4 packs would have cost exactly $20).

The inequality 5x > 20 represents this situation, as it demonstrates that Dave spent more than $20 on the card packs.

To determine the minimum number of packs Dave bought, we can solve the inequality for x: 5x > 20 x > 4

Therefore, Dave bought more than 4 packs of trading cards to obtain all the cards he desired.

Based on the given mean delivery time of 10:28am and the standard deviation of 0:55 mins, the estimated times within which 95% of the deliveries are made is (a) between 8:38 am and 12:18 pm.

To calculate this interval, we need to use the z-score formula, where we find the z-score corresponding to the 95th percentile, which is 1.96. Then, we multiply this z-score by the standard deviation and add/subtract it from the mean to get the upper and lower bounds of the interval.

The upper bound is calculated as 10:28 + (1.96 x 0:55) = 12:18 pm, and the lower bound is calculated as 10:28 - (1.96 x 0:55) = 8:38 am.

Therefore, we can conclude that the interval between 8:38 am and 12:18 pm represents the estimated times within which 95% of the deliveries are made based on the given mean delivery time and standard deviation.

Step-by-step explanation:

If you start by distributing the parentheses, you will end up with this equation:

5x - 0.2x + 2 = 7.2 + 4.4x + 26.4

After that, you can subtract the right side from both sides to combine like terms. It should end up like this:

5x - 0.2x + 2 - 7.2 - 4.4x - 26.4 = 0

Once you combine the like terms it will end up like this:

0.4x - 21.6 = 0

Now, you should add 21.6 to both sides to separate the terms:

0.4x = 21.6

From here, you should divide both sides by the coefficient of x (0.4) to get your answer:

x = 54

The second derivative is negative at x = 0.408, we know that this critical point corresponds to a local maximum.

Calculus uses the second derivative test as a technique to identify a function's concavity and local extrema. It entails taking a function's second derivative and checking the sign at a crucial point. A local minimum or maximum is indicated by a positive second derivative and the opposite is true for a negative second derivative.

To find the critical points of the function\(f(x) = -64x^4 + 42x - 4\), we need to find where the derivative of the function is equal to zero or undefined. Taking the derivative of f(x) gives us:

\(f'(x) = -256x^3 + 42\)

Setting\(f'(x) = 0\), we can solve for x:

\(-256x^3 + 42 = 0\\x^3 = 42/256\\x = (42/256)^(1/3) = 0.408\)

So the only critical point of the function is x = 0.408.

To apply the second derivative test, we need to take the second derivative of f'(x):

\(f''(x) = -768x^2\)

Plugging in our critical point x = 0.408, we get:

\(f''(0.408) = -768(0.408)^2 = -125.3\)

Since the second derivative is negative at x = 0.408, we know that this critical point corresponds to a local maximum.

The probability of the arrow landing on an odd number is the number of odd numbers divided by the total number of possible outcomes. Therefore, the probability of the arrow landing on an odd number is  0.5 or 50%.


To find the probability that the arrow will point at an odd number on a circular board with 8 equal parts, we'll first determine the total number of odd numbers present and then divide that by the total number of possible outcomes.

Step 1: Identify the odd numbers on the board. They are 1, 3, 5, and 7. The game consists of spinning the arrow on a circular board with 8 equal parts, which means there are 8 possible outcomes or numbers. Since we want to know the probability of landing on an odd number, we need to count how many odd numbers are on the board. In this case, there are four odd numbers: 1, 3, 5, and 7.

Step 2: Count the total number of odd numbers. There are 4 odd numbers.

Step 3: Count the total number of possible outcomes. Since the board is divided into 8 equal parts, there are 8 possible outcomes.

Step 4: Calculate the probability. The probability of the arrow pointing at an odd number is the number of odd numbers divided by the total number of possible outcomes.

Probability = (Number of odd numbers) / (Total number of possible outcomes)
Probability of landing on an odd number = Number of odd numbers / Total number of possible outcomes
Probability of landing on an odd number = 4 / 8

Step 5: Simplify the fraction. The probability of the arrow pointing at an odd number is 1/2 or 50%.

So, the probability that the arrow will point at an odd number is 1/2 or 50%.

The function y = 7|x + 1| - 5 can be written as a Piecewise Function as follows,

               7x + 2                for x > -1

y   =

              -7x - 12               for x < -1

Given, a function y = 7|x + 1| - 5

Now, we have to write the given function as a piecewise function

|x + 1| = (x + 1) for x > -1 and

|x + 1| = - (x + 1) for x < -1

So, the given function can be written as a piecewise function

               7(x + 1) - 5                for x > -1

y   =

              -7(x + 1) - 5                for x < -1

On simplifying, we get

               7x + 2                for x > -1

y   =

              -7x - 12               for x < -1

Hence, the given function y = 7|x + 1| - 5 can be written as a Piecewise Function as follows,

Answer:

Step-by-step explanation:

The system of equations is:

x^2 = y

x^2 + y^2 = 9

Substituting the first equation into the second, we get:

x^2 + (x^2)^2 = 9

x^4 + x^2 - 9 = 0

Using the quadratic formula, we can solve for x^2:

x^2 = (-1 ± sqrt(37))/2

Taking the positive root, we get:

x^2 = (-1 + sqrt(37))/2

Substituting this back into the first equation, we get:

y = (-1 + sqrt(37))/2

So the solution is the point (sqrt((-1 + sqrt(37))/2), (-1 + sqrt(37))/2)

Looking at the graphs, only graph (d) contains the point (sqrt((-1 + sqrt(37))/2), (-1 + sqrt(37))/2), so the answer is (d).

Answer:

The hand moved \(\bf \frac{3}{4}\) of a complete turn.

Step-by-step explanation:

The hand moved from 3 to 12, that is, it moved:

12 - 3 = 9 hours

In a clock, 12 hours represent a complete turn.

∴ Using the unitary method:

12 hours    ⇒     1 turn

1 hour        ⇒     \(\frac{1}{12}\) turns

9 hours     ⇒     \(\frac{1}{12}\)  × 9 = \(\frac{9}{12}\)

                                     = \(\bf \frac{3}{4}\) turns    (simplified)

∴ The hand moved \(\bf \frac{3}{4}\) of a complete turn.

The answer is  \(\boxed{\frac{3}{4}}\).

To find the fraction of a complete turn it moved in this case, take the ratio between hours covered between 3 and 12, and the hours covered in a complete turn.

Answer:

A. 27.50 = 5.50 + 2.75h

B. 8 hours

C. 9 hours

Step-by-step explanation:

Total spent = $27.50

Base fee = $5.50

Hourly rate = $2.75

A. Create an equation that can be used to determine how many additional hours, ℎ, Rose parked her car in the garage

Total cost = fixed cost + variable cost

27.50 = 5.50 + 2.75h

B: Solve the equation to determine the number of additional hours, ℎ, Rose parked her car in the garage.

27.50 = 5.50 + 2.75h

Subtract 5.50 from both sides

27.50 - 5.50 = 5.50 - 5.50 + 2.75h

22 = 2.75h

Divide both sides by 2.75

h = 22/2.75

= 8

h = 8 hours

C: What is the total number of hours that Rose parked her car in the garage

Total number of hours = first hour + additional hours
