The constant proportionality is 15, which means that for every box of candy, there are 15 pieces of candy. The equation is 15x.

A variable in mathematics is a sign that denotes a value that may vary, as opposed to a constant, which is a set number that never changes. Variables are used to represent unknown or changing quantities, such as time (t) or the distance (d) travelled by an item, whereas constants are used to represent fixed numerical values, such as pi or the speed of light (c). In contrast to variables, which are often represented by lowercase letters, constants are typically represented by capital letters. In mathematical equations and formulae, the distinction between constants and variables establishes which values are fixed and which values are subject to change.

The slope of line is given as:

m = (change in y) / (change in x)

Substitute the values from the table:

m = (135 - 150) / (9 - 10) = -15/-1 = 15

For the equation to be of the form y = mx we have:

y = mx + b

150 = 15(10) + b

b = 0

Substituting the values the equation is:

y = 15x

Hence, the constant proportionality is 15, which means that for every box of candy, there are 15 pieces of candy. The equation is 15x.

The volume of the box is 1000 cubic inches. False, the government does not ensure that you always get paid in international transportation; payment is determined by contracts and agreements between parties.

3: To find the volume of the box in cubic inches, we need to convert the dimensions from centimeters to inches. Given that 1 inch is approximately equal to 2.5 cm, we can calculate the volume as follows:

Length in inches = 25 cm / 2.5 cm/inch = 10 inches

Width in inches = 25 cm / 2.5 cm/inch = 10 inches

Height in inches = 25 cm / 2.5 cm/inch = 10 inches

Volume = Length × Width × Height = 10 inches × 10 inches × 10 inches = 1000 cubic inches

Therefore, the volume of the box is 1000 cubic inches.

5: The statement "International transportation is regulated by the government which ensures that you always get paid" is false. International agencies (such the International Maritime Organization and the International Civil Aviation Organization) as well as standards set by the private sector all have a role in regulating international transportation.

The correct option that describes the set being linearly dependent is option A: f2(x) = c1 f1(x) + c2 f3(x) + c3 f4(x).

If one of the functions in the set can be expressed as a linear combination of the other functions, it implies that the set is linearly dependent. In option A, f2(x) can be written as a linear combination of f1(x), f3(x), and f4(x), indicating that the set is linearly dependent.

Option B does not necessarily imply linear dependence, as it represents a specific linear combination of the functions rather than one function being a linear combination of the others.

Option C refers to the Wronskian, which is a concept used to test linear independence of functions, but its value not being zero does not necessarily imply linear dependence.

The Wilcoxon signed-rank test is employed to see if there is a substantial difference between two related samples. Here the new cognitive therapy group and placebo group are related samples as they both belong to the same sample of cognitive therapy's study. The Wilcoxon signed-rank test is performed on the rank-based data as the data is not normally distributed. Following is the calculation for Wilcoxon’s signed rank test:The null hypothesis for the Wilcoxon signed-rank test is that there is no difference between the new cognitive therapy and placebo treatments. While the alternative hypothesis is that there is a difference between the two treatments.

The Wilcoxon signed-rank test is performed as follows:
Rank all the data, with the lowest value being ranked 1 and the highest value being ranked 12.
Calculate the difference between the new cognitive therapy and placebo group scores.
Take the absolute values of the differences.
Rank the differences in ascending order and ignore the signs.
Calculate the sum of the ranks of the new cognitive therapy group.
Calculate the test statistic T.
For this dataset, the calculations of the Wilcoxon signed-rank test are as follows:
Data Ranked (New therapy) Difference Absolute Difference Ranked Differences + Rank Therapy Differences - Rank Placebo 5 1 4 3 4 4 6 2 4 4 2 2 4 4 8 7 1 1 1 12 10 2 2 3 5 1 6 13 12 1 8 7 7 4 4 1 5 5 5 1 14 13 1 2 1 15 7 8 7 7 5 9 10 3 5 8 56 12 44 12 12 11 7 Total 49
Calculating T:

\($$T =\) \(\frac{Total\ of\ positive\ ranks - \frac{n(n+1)}{4}}{\sqrt{\frac{n(n+1)(2n+1)}{24}}}$$\)

Here, n is the number of pairs, which is 12.
T = 3.52
Using the Wilcoxon signed-rank test table, the critical value at the 0.05 level for n = 12 is 18.
Since T (3.52) is less than the critical value (18), the null hypothesis cannot be rejected.
There is no evidence to suggest that there is a difference between the new cognitive therapy and placebo treatments.

Answer:

x = 46

Step-by-step explanation:

These 2 angles would add up to 180 degrees.

So 41 + (3x+1) = 180

Let's solve for x.

41 + 3x + 1 = 180

Combine like terms.

42 + 3x = 180

subtract 42 from both sides

3x = 180-42

3x = 138

divide both sides by 3

x = 46

The value of f(5) is 47.

What is face value?

Face value is the amount that any security issuer declared when it was first issued in dollars. The core idea behind the stock market is the nominal value.

If publicly traded companies use IPOs to sell stocks, this price stays constant. For instance, the place value of 5 in 5432 is 5000 while its face value is 5.

Solution Explained:

Given, f(1) = 1 and f(n) = -3f(n-1) + n

First we find,

f(2) = -3f(2-1) + 2 = -3f(1) + 2 = -1

f(3) = -3f(3-1) + 3 = -3f(2) + 3 = 6

f(4) = -3f(4-1) + 4 = -3f(3) + 4 = - 14

Now, we calculate f(5)

f(5) = -3f(5-1) + 5 = -3f(4) + 5 = 47

Answer:

A = 72, P = 38

Step-by-step explanation:

Area can be found by getting the area of the overall figure, and then subtracting the blank space in the corner

12 * 7 = 84

3 * 4 = 12(invisible rectangle in top right)

84 - 12 = 72

Perimeter can be found by adding all of the sides

12 + 7 + (12-4) + 3 + 4 + (7-4)

The numbers in brackets are the unlabeled sides on the top and left.

Answer:

\(P=38\\ A=72\)

Step-by-step explanation:

To find the perimeter (P), add up all of the side lengths of the figure:

(numbers in parenthesis are the unlabeled values in the figure).

\(12+7+(8)+3+4+(4)=38\)

To find the area of the figure (A), multiply the length and width of the original rectangle \((12*7=84)\). Then, subtract this amount (84) minus the area of the missing rectangle in the top left corner \((4*3=12)\).

Subtract the required values: \(84-12=72\).

Therefore, the perimeter of the figure is 38 units, and the area of the figure is 72 units.

The function representing the amount of oil in the tank at any time t is given by:

h(t) = 2000 + ∫et() - lt() dt

This function h(t) represents the accumulation of oil in the tank over time. The integral term represents the net change in the amount of oil in the tank over time, taking into account both the rate at which oil enters the tank and the rate at which it leaves.

The initial value of h(0) = 2000 represents the starting amount of oil in the tank at midnight. By finding the definite integral of et() - lt() over a given time interval, we can determine the net change in oil volume during that time and thus find the amount of oil in the tank at any given time t.

Answer:

The population after x years will be P = 29000 + 700x

Let the population after the years be represented by P

Population of the town in 2003 = 29000

Annual increase in growth = 700

Then, the population after x years will be:

P = 29000 + 700(x)

P = 29000 + 700x

Therefore, the population will be P = 29000 + 700x.

When an inequality is multiplied or divided by a negative number, the inequality sign will flip, meaning it will change its direction. For example, if you have a > b and you multiply or divide both sides by a negative number, the inequality will become a < b. This is because the relationship between the values reverses when multiplied or divided by a negative number.

Explanation:

When an inequality is multiplied or divided by a negative number, the direction of the inequality sign is flipped. This is because multiplication or division by a negative number, results in a reversal of the order of the numbers on the number line.

To see why this happens, consider the following example:

Suppose we have the inequality x < 5. If we multiply both sides of this inequality by -1, we get -x > -5. Notice that we have flipped the inequality sign from "<" to ">". This is because multiplying by -1 changes the sign of x to its opposite, and also changes the sign of 5 to its opposite, resulting in a reversal of the order of the numbers on the number line.

Similarly, if we divide both sides of the inequality x > 3 by -2, we get (-1/2)x < (-3/2). Here, we have again flipped the inequality sign from ">" to "<". This is because dividing by a negative number also changes the order of the numbers on the number line.

In general, if we have an inequality of the form a < b or a > b, where a and b are real numbers, and we multiply or divide both sides by a negative number, we obtain:

If we multiply by a negative number, the inequality sign is flipped. For example, if a < b and c < 0, then ac > bc.

If we divide by a negative number, the inequality sign is also flipped. For example, if a > b and c < 0, then a/c < b/c.

Therefore, it is important to be mindful of the signs of the numbers involved when performing operations on inequalities. If we multiply or divide by a negative number, we must flip the direction of the inequality sign accordingly.

Answer:

m<CGD = 26°

m<CGF = 100°

Step-by-step explanation:

m<CGD = 2x - 2

m<EGF = 37

m<CGF = 7x + 2

Since GE bisects <DGF, m<DGF = 2*m<EGF.

m<DGF = 2*37 = 74°

m<CGD + m<DGF = m<CGF (angle addition postulate)

(2x - 2) + (74) = (7x + 2)

Find the value of x using the equation above.

2x - 2 + 74 = 7x + 2

Collect like terms

2x + 72 = 7x + 2

-2 + 72 = 7x - 2x

70 = 5x

70/5 = 5x/5

14 = x

x = 14

m<CGD = 2x - 2

Plug in the value of x

m<CGD = 2(14) - 2 = 28 - 2

m<CGD = 26°

m<CGF = 7x + 2

m<CGF = 7(14) + 2 = 98 + 2

m<CGF = 100°

D. The slope is -2. The y-intercept is (0,3)

Step-by-step explanation:

You can use any two points.

Let's use the first two points: (0, 3), (2, -1)

slope = (y_2 - y_1)/(x_2 - x_1)

slope = (-1 - 3)/(2 - 0)

slope = -4/2

slope = -2

The y-intercept occurs when x = 0. For x = 0, y = 3, so the y-intercept is 3 which means the point (0, 3).

The slope of a line does not necessarily correspond to the true rate constant, k. The slope of a line in a plot of ln([A]t/[A]0) vs time is equal to -k, but this is only true under certain conditions, such as when the reaction is first-order with respect to reactant A.

In general, the slope of a line can only give an estimate of the rate constant. The expression that the slope equals is dependent on the specific plot and reaction conditions.

The slope of the line does not necessarily correspond to the true rate constant, k, directly. This is because the relationship between the slope and the rate constant depends on the order of the reaction.

For a first-order reaction, the equation is ln[A] = -kt + ln[A₀]. In this case, the slope of the line (when plotting ln[A] vs. time) corresponds to the true rate constant, k, and is negative.

For a second-order reaction, the equation is 1/[A] = kt + 1/[A₀]. In this case, the slope of the line (when plotting 1/[A] vs. time) corresponds to the true rate constant, k, and is positive.

So, the expression that the slope equals depends on the order of the reaction. For a first-order reaction, the slope equals -k, and for a second-order reaction, the slope equals k.
