Answer: 6^4

Step-by-step explanation:

You have 6^5 / 6 which is basically 6^5 / 6^1

When you are dividing exponents with the same base, you can subtract the exponent from each other.

When you do this, you get 6^4

The percentage of students scoring 84 or more in the exam is 99.18%.

Given, Mean test score = 72,

Standard deviation = 5.

We are supposed to find the percentage of students scoring 84 or more in the exam.

To find the percentage of students scoring 84 or more in the exam, we will use the following steps:

First, we need to find the z-score associated with 84.

Let us assume that z is the z-score corresponding to the value 84, then;

z = (84 - 72) / 5 = 2.4

Now, we have the value of z, we can find the percentage of students scoring 84 or more in the exam using the normal distribution table.

The percentage is the area under the normal distribution curve to the right of the z-score.

To find the area using the normal distribution table, we need to look for the value 2.4 in the z-table. Since 2.4 is not exactly listed in the z-table, we will use the value for 2.4 closest to it.

Using the z-table, the value closest to 2.4 is 0.9918.

Therefore, the percentage of students scoring 84 or more in the exam is;

P(Z > 2.4) = 0.9918 × 100 = 99.18%.

The original equation and the orthogonal equation are the same, we can conclude that the family of conics with the same focus x^2/a^2+C + y^2/b^2+C = 1 is its own orthogonal family of curves.

To show that the family of conics with the same focus x^2/a^2+C + y^2/b^2+C = 1 is its own orthogonal family of curves, we need to take the derivative of the equation and set it equal to -1/b^2, the slope of the orthogonal line.

First, we take the derivative of the equation with respect to x:

2x/a^2 = -2y/b^2 * dy/dx

Simplifying, we get:

dy/dx = -b^2*x/a^2*y

Now, we set this equal to -1/b^2:

-b^2*x/a^2*y = -1/b^2

Cross-multiplying and simplifying, we get:

x/a^2*y = 1/b^2

Finally, we can rearrange this equation to get:

y = b^2*x/a^2

This equation represents the orthogonal family of curves to the original family of conics. Since the original equation and the orthogonal equation are the same, we can conclude that the family of conics with the same focus x^2/a^2+C + y^2/b^2+C = 1 is its own orthogonal family of curves.

Number line model represented in option C represents the expression 6 + (-2).

Number line is a pictorial representation of numbers, both negative and non-negative numbers, written on a horizontal straight line within specific intervals.

Number line are used to determine basic mathematical operations like addition, subtraction, division and multiplication.

So here, we are adding the value -2 with 6.

First draw an upward arrow from 0 to 6 in order to represent that we are initiating the addition process with 6.

Then the number -2 added to 6 implies that the number 2 is actually deducting from 6.

So we draw a downward arrow to unit units from 6.

Then we get the number 4 corresponding to the point where the arrow ends.

Hence, option C is the model which represents the expression 6 + (-2).

g) Without these details, it is not possible to conduct the t-test.

Scatter diagram is a visual representation of data points plotted on a Cartesian coordinate system. It is used to display the relationship between two variables.

a) To develop a scatter diagram, plot the given data points (xi, yi) on a graph, where xi represents the values of the independent variable and yi represents the values of the dependent variable. The  scatter diagram is shown below.

b) To develop the estimated regression equation, we need to find the equation of the line that best fits the data points. This line represents the relationship between the independent variable (x) and the dependent variable (y). The estimated regression equation is given by:

y = a + bx

where "a" represents the y-intercept and "b" represents the slope of the line.

Using statistical methods such as least squares regression, the estimated regression equation can be calculated. In this case, the estimated regression equation is:

y = 5.47 + 1.18x

c) To predict the value of y when x = 6, substitute x = 6 into the estimated regression equation:

y = 5.47 + 1.18(6)

y = 12.65

Therefore, when x = 6, the estimated value of y is approximately 12.65.

d) The percentage of the total sum of squares accounted for by the estimated regression equation is given by the coefficient of determination (R-squared). It represents the proportion of the total variation in the dependent variable (y) that can be explained by the independent variable (x) through the estimated regression equation.

In this case, the coefficient of determination (R-squared) is 0.6563, or approximately 65.63%. This means that the estimated regression equation can account for about 65.63% of the total variation in the dependent variable.

e) The sample correlation coefficient (r) measures the strength and direction of the linear relationship between the two variables. In this case, the sample correlation coefficient is approximately 0.8107, indicating a strong positive linear relationship between the variables.

f) The standard error of the estimate measures the average distance between the observed data points and the predicted values from the regression equation. In this case, the standard error of the estimate is approximately 5.10.

Step-by-step explanation:

so you want to input the numbers into variables so for (p+q)^2 you input p as 4 and q as 8 (4+8)^2 and then you add 4+8 which is 12. Then you have to do 12 to the power of 2 which is 12x12 and the answer to that is 144. For the bottom you input p as 4 and then for -2q you have to input the 8, -2(8) and that equals to -16 so then it's 4-16 so it equals to -12. Then you have to do -12 divided by 12 which equals to 1.

Game theory is a branch of mathematics that deals with the study of decision-making in situations where two or more individuals or groups are involved.

It aims to predict the outcomes of these decisions by analyzing the strategies and incentives of each player. In the context of oligopoly, game theory helps us understand how firms interact and compete with each other in a market. Oligopoly is a market structure where a small number of large firms dominate the market. In this situation, firms must take into account the actions and reactions of their competitors when making decisions about pricing, production, and advertising. Game theory provides a framework for analyzing the strategic behavior of firms in an oligopolistic market. It helps us understand how firms may collude or engage in strategic behavior to gain an advantage over their competitors. It also provides insights into how changes in market conditions or government regulations can affect the behavior of firms in an oligopoly. I can say that visual aids and real-world examples can be helpful in understanding complex concepts like game theory. Video clips can be a great way to illustrate key ideas and make them more accessible to a wider audience. However, it is important to remember that game theory is a highly technical field and may require a significant amount of study and practice to fully grasp its concepts and applications.

Answer:

(1,5)

Step-by-step explanation:

x = 1

y = 8

If you move down 3 units, it means the y would be lower. This is because y is the vertical value in a pair of coordinates.

8-3 = 5

Answer:

(1, 5)

Step-by-step explanation:

A coordinate defined as point (x, y) is called Cartesian Coordinate. The x-coordinate represents right-left direction while the y-coordinate represents up-down direction.

Its transformation depends on how would you move the coordinate point. An example is if you start with (x, y) point and move to right 3 units, our new position will be at (x + 3, y).

Properties

Suppose we have point (x, y), if we move to right “a” units then the new point will be (x + a, y)

If we move (x, y) to left “a” units, our new point will be (x - a, y)

If we shift (x, y) up “a units”, you’ll get (x, y + a)

If we shift (x, y) down “a units”, we’ll have (x, y - a)

Suppose you start at (1, 8) and you move down 3 units, you can apply the transformation property to find your new position.

Since you move down, this means you are dealing with y-coordinate only so you’ll apply property of (x, y - a)

You’ll have (1, 8 - 3) which equals to (1, 5).

Hence, you’ll end at (1, 5).

Answer:

35 degrees

Step-by-step explanation:

for all positive angles less than 360°, if csc (2x+30°)= cos (3y-15°), the sum of x and y is?​

Let the given expression be equal to 1, hence;

csc (2x+30°)= cos (3y-15°) = 1

csc (2x+30°) = 1

1/sin(2x+30) = 1

1 = sin(2x+30)

sin(2x+30) = 1

2x+30 = arcsin(1)

2x+30 = 90

2x = 90-30

2x = 60

x = 60/2

x = 30 degrees

Get the value of y;

cos (3y-15°) = 1

3y - 15 = arccos (1)

3y - 15= 0

3y = 0+15

3y = 15

y = 15/3

y = 5

Sum of x and y;

x+y = 30 + 5

x+y = 35degrees

Hence the sum of x and y is 35 degrees

To show that a^(t-1) + a^(t-2) + ... + 1 is congruent to 0 (mod p), we can use the fact that a has order t (mod p).

Recall that the order of an integer a (mod p) is the smallest positive integer k such that a^k is congruent to 1 (mod p). Therefore, we know that a^t is congruent to 1 (mod p) and that a^k is not congruent to 1 (mod p) for any positive integer k < t.

Now, let's consider the expression a^(t-1) + a^(t-2) + ... + 1. We can write this as:

a^(t-1) + a^(t-2) + ... + a + 1 - a^t + a^t

Notice that we added and subtracted a^t in the expression. We can do this because adding or subtracting a multiple of p does not change the congruence class (mod p).

Now, let's focus on the first part of the expression:

a^(t-1) + a^(t-2) + ... + a + 1 - a^t

We can factor out an "a" from each term in the first part to get:

a(a^(t-2) + a^(t-3) + ... + a^2 + a + 1) - a^t

Notice that the expression in the parentheses is a geometric series with common ratio a and first term 1. Therefore, we can use the formula for the sum of a geometric series to get:

a^(t-1) + a^(t-2) + ... + a + 1 = (a^t - 1)/(a - 1)

Plugging this into our original expression, we get:

(a^t - 1)/(a - 1) - a^t + a^t

Simplifying, we get:
(a^t - 1)/(a - 1)
Now, we can use the fact that a has order t (mod p) to show that this expression is congruent to 0 (mod p).

Since a has order t (mod p), we know that a^t is congruent to 1 (mod p) and that a^k is not congruent to 1 (mod p) for any positive integer k < t. Therefore, a - 1 is not congruent to 0 (mod p), since otherwise we would have a^k congruent to 1 (mod p) for some k < t.

Therefore, we can invert a - 1 (mod p) to get a unique solution for x such that (a - 1)x is congruent to 1 (mod p). Multiplying both sides of the expression (a^t - 1)/(a - 1) by x, we get:

(a^t - 1)x/(a - 1) congruent to x(0) (mod p)

Simplifying, we get:

(a^t - 1)x/(a - 1) congruent to 0 (mod p)

Since a - 1 is not congruent to 0 (mod p), we can multiply both sides by (a - 1) to get:

a^t - 1 congruent to 0 (mod p)

Therefore, we have shown that a^(t-1) + a^(t-2) + ... + 1 is congruent to 0 (mod p), as desired.

The Triangle RST is missing, so i have attached it.

Answer:

A) TZ = 34

B) ZW = 17

C) SY = 69

D) XZ = 21

Step-by-step explanation:

To form the centroid, we see median drawn from the centre of all three sides.

Thus means the 3 sides are divided into 2 and as such;

XS = XT

YR = YT

WR = WT

Now, for median that forms centroid, the two parts are usually not the same length but instead in the ratio 2:1. That means one portion of the line segment is twice the length of the other.

Thus, by inspection of the given triangle, we can say that;

SZ = 2(ZY)

TZ = 2(ZW)

RZ = 2(XZ)

A) Now, we are given TW = 51

TW is made up of TZ and ZW

But since TZ : ZW = 2:1, it means that;

TZ = ⅔ × TW

TZ = ⅔ × 51

TZ = 34

B) From earlier, we saw that TZ = 2(ZW).

Thus; 34 = 2(ZW)

ZW = 34/2

ZW = 17

C) We are given ZY = 23.

From earlier, we saw that;SZ = 2(ZY)

Thus; SZ = 2(23)

SZ = 46

From the attached image we can see that;

SY = SZ + ZY

Thus;

SY = 46 + 23

SY = 69

D) We are given RZ = 42.

From earlier, we saw that;

RZ = 2(XZ)

Thus;

42 = 2(XZ)

XZ = 42/2

XZ = 21

Amount of interest on loan at Rimrock Bank, using ordinary interest at a rate of 15%, is $48,750 and at rate of 14.5%, is $47,125. In Southside National Bank , interest at a rate of 15%, is $49,500.

To compete with Rimrock Bank's offer, Southside National Bank would need to quote a rate of 14.38% using exact interest.                                    (a) To calculate the amount of interest on the loan at Rimrock Bank, we use the formula I = PRT, where I is the interest, P is the principal amount, R is the interest rate, and T is the time in years. Plugging in the values, we have I = $1,300,000 * 0.15 * (90/365) = $48,750.

(b) The amount of interest on the loan at Southside National Bank using exact interest is calculated the same way as in part (a), resulting in I = $1,300,000 * 0.15 * (90/360) = $49,500.                                                        (c) Similarly, using the same formula, we find the interest on the loan at Rimrock Bank with a rate of 14.5% to be I = $1,300,000 * 0.145 * (90/365) = $47,125.

(d) To determine the rate at which Southside National Bank should quote to compete with Rimrock Bank's last offer, we subtract the given interest difference of $1,125 from the interest calculated in part (b). Solving for R, we have $48,750 - $1,125 = $1,300,000 * R * (90/360). Solving this equation results in R ≈ 0.1438, which is 14.38% rounded to the nearest hundredth of a percent.
