The role of the media in a democracy is essential for a free and informed society.

Democracy is a form of government in which power is held by the people through their elected representatives. It is based on the principle of political equality and rule of law, where all citizens have an equal say in the decisions that affect their lives. It is a system of government in which citizens have the right to vote, stand for office, and participate in decision-making processes that shape their communities and the nation as a whole.

The media acts as a watchdog for the government, keeping them accountable and ensuring that the people are aware of the decisions being made. It also provides a platform for citizens to express their opinions and to discuss important issues. Additionally, the media can help to educate the public on important topics, such as politics, economics, and social issues. This helps to ensure that citizens are well informed and can make informed decisions when voting or engaging in other forms of political participation.

The graph of the linear function y = -3x is attached below.

A linear function is a type of mathematical function that describes a straight line relationship between two variables. It is defined by an equation of the form:

y = mx + b

where y is the dependent variable (output), x is the independent variable (input), m is the slope of the line, and b is the y-intercept (the point where the line crosses the y-axis).

In a graph, a linear function will always be a straight line. The slope (m) tells you how steep the line is, and the y-intercept (b) tells you where the line crosses the y-axis. The slope-intercept form is y = mx + b

The linear function given is y = -3x

From the table of values;

f(x) = -3x

f(-1) = -3(-1)

f(-1) = 3

f(0) = -3(0)

f(0) = 0

f(1) = -3(1)

f(1) = -3

Plotting this on a graph, our slope is -3 and since it doesn't have a            y - intercept, the graph passes through the origin.

16.25 percent the total number of students on the honor roll decreased.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, last year at a certain high school, there were 140 boys on the honor roll and 100 girls on the honor roll.

This year, the number of boys on the honor roll decreased by 25% and the number of girls on the honor roll decreased by 6%.

So, the number of boys = 140 - 25% of 140

= 140 - 0.25×140

= 140 - 35

= 105

The number of girls = 100 - 6% of 100

= 96

Total number of students last year = 140+100

= 240

Total number of students this year = 105+96

= 201

Difference = 240-201

= 39

Now, percentage decrease = 39/240 ×100

= 0.1625×100

= 16.25%

Hence, 16.25 percent the total number of students on the honor roll decreased.

Answer:

80 months

Step-by-step explanation:

If the present monthly heating costs average $300, but the insulation is expected to reduce heating costs by 10%, then there will be a monthly saving of 10%:

[tex]\implies \rm Monthly\;saving=10\%\;of\;\$300 =\dfrac{10}{100} \times \$300=\$30[/tex]

To calculate how many months it will take to recover the cost of the insulation, divide the cost of installing the insulation by the monthly saving:

[tex]\implies \rm Number\;of\;months=\dfrac{\$2400}{\$30}=80[/tex]

Therefore, it will take 80 months to recover the cost of the insulation.

Answer:

80 months

Step-by-step explanation:

The expected monthly savings from the insulation are: $300 × 10% = $30.

So, the number of months required to recover the cost of the insulation, $2400, is $2400/$30 = 80 months.

Answer:

graph the line -2x+3 as a dotted line and shade in below that line.

Step-by-step explanation:

Linear inequalities are an inequality... which contain linear equations. To graph these linear inequalities it helps to first just graph the linear equation and then based on the inequality whether it's less than, less than or equal to, greater than, or greater than or equal to we would draw above or below this line and with a solid or dotted line.

So we're given the equation: [tex]y < -2x+3[/tex] it helps to first just graph the -2x + 3, which we can do by starting at the y-intercept of 3 and then going down 2 and going right 1 as defined by the slope -2. Likewise we can go up 2 and go left 1 from the y-intercept to define points to the left of the y-axis.

Now from here we look at the inequality: [tex]y < -2x+3[/tex], it's telling us y values less than -2x + 3, so we want to be below the line we just graphed, so shade below the line. One thing to note is it's a less than and not a less than or equal to so the line it self is not included, meaning we draw a dotted line.

There is no sufficient evidence to keep up the claim that the bags are underfilled.

We are given;

n = 27 bags

Sample mean;X = 402 gram

Population mean;μ = 404 gram

Variance = 676

We know that, standard deviation(σ) = √variance

Thus;

σ = √676

σ = 26

The hypotheses are;

Null hypothesis; H0: μ = 404

Alternative hypothesis; HA: μ < 404

Let's find the z-score from the formula;

z = (X - μ)/(√σ/n)

z = (402 - 404)/√(26/27)

z = -2.04

The z-distribution table attached, we have a p-value of 0.02068

Answer:

The future value of the annuity is $14,170.

The total amount invested is $39,000.

The interest earned is $14,170 - $39,000 = -$24,830

Step-by-step explanation:

The future value of the annuity can be calculated using the formula:

FV = P * (1 + r)^n

where FV is the future value, P is the annual payment, r is the annual interest rate, and n is the number of years.

In this case, the annual payment is $13,000, the annual interest rate is 3%, and the number of years is 3. So, the calculation is:

FV = $13,000 * (1 + 0.03)^3

FV = $13,000 * 1.09

FV = $14,170

So, the future value of the annuity is $14,170.

How much was invested?

The annual payment is $13,000. We multiply that by the number of years of the investment, 3 years. The total amount invested is $39,000.

How much interest was earned?

We can calculate the interest earned by subtracting the total amount invested from the future value.

The interest earned is $14,170 - $39,000 = -$24,830

So, the future value of the annuity is $14,170, the total amount invested is $39,000 and the interest earned is -$24,830.

Due to length restriction, we kindly invite to check the explanation for further details on profit and risk minimization.

In this problem we find the case of a person that invests a lot of money, distributed in two investments. We need to determine how much money must be invested in each plan to earn a desired return:

R = (C - c) · (r₁ / 100) + c · (r₂ / 100)

Where:

Part A - If we know that R = 9300, C = 91000, r₁ = 10 and r₂ = 11, then the amount invested in the most risky investment:

9300 = (91000 - c) · (10 / 100) + c · (11 / 100)

930000 = (91000 - c) · 10 + c · 11

930000 = 910000 - 10 · c + 11 · c

c = 20000

The person must invest $ 20000 in the least risky investment and $ 71000 in the most risky investment.

Answer:

5 cookies and 4 brownies

Step-by-step explanation:

First, let's assign variable for cookies and brownies:

x= cookies

y= brownies

Now, let's create an equation with the information given to us:

[Note: "#of brownies + 8" equals the number of cookies because, in the question, we are told He bought 8 more cookies than brownies ]

cost of a brownie * #of brownies +  cost of a cookie * (#of brownies + 8 ) = $7.50

1.25y + 0.5x = 7.5

Since we want to solve the problem graphically, let's solve our equation for y, so it can be graphed:

1.25y + 0.5x = 7.5   [Subtract 0.5x from both sides]

1.25y = -0.5x + 7.5   [Divide both sides by 1.25 so we just get y]

y = -0.4x + 6

This equation will be used to determine what we can buy at the bakery with $7.50.

Now, we will graph the equation (see attached image). What we will see is that as x increases, y decreases. This makes sence, since the number of brownies (y) you can buy with your budget decreases as the number of cookies (x) you buy increases. Lastly, since we can't buy a fraction of a cookie, we want to find a coordinate on the line that has both a natural [see definition if confused] x and y value. To do this, we will look at the graph and see if a x value of 1 gives us a natural y value. If not, we go on to 2 and see if it gives us a natural y value. This continues until you find both a natural x and y value. This will happen at x=5 and y=4. This answer tells us that, with $7.50, Qasim and his children bought 5 cookies and 4 brownies.

The estimate of the total number of litter complaints for planet Yellow is:

Between 3,835 and 20,800 complaints.

The average number of complaints about litter from the sample of 250 cities is 3.2 ± 0.59. This means that the actual number of complaints could be anywhere from 2.61 to 3.79. To estimate the total number of complaints for all 6,500 cities on planet Yellow, we need to multiply the sample average by the number of cities.

If we assume the lower end of the sample average (2.61), then the total number of complaints would be:

2.61 x 6,500 = 17,065

If we assume the upper end of the sample average (3.79), then the total number of complaints would be:

3.79 x 6,500 = 24,935

So the total number of complaints for planet Yellow is estimated to be between 17,065 and 24,935, which is equivalent to the range of:

Between 3,835 and 20,800 complaints.

The equations of the tangent to the curve when x = 1 are;

[tex]y = 5\frac{1}{3}\cdot x - 1\frac{1}{3}[/tex]

[tex]y = 1\frac{1}{3} - \frac{1}{3} \cdot x[/tex]

The tangent to a curve at a point, is the line that best fits the rate of change of the curve at the specified point.

The equation to be differentiated in the question is; y² - 5·x·y + 4·x = 0

The derivative of the above equation using the differentiation of a product is as follows;

2·y·y' - (5·y + 5·x·y') + 4 = 0

2·y·y' - 5·y - 5·x·y' + 4 = 0

2·y·y' - 5·x·y' - 5·y + 4 = 0

y'·(2·y - 5·x) - 5·y + 4 = 0

The slope of the curve, therefore is; y' = (5·y - 4)/(2·y - 5·x)

At x = 1, we get;

y² - 5·y + 4 = 0

(y - 4)·(y - 1) = 0

At x = 1, y = 4 and y = 1

Therefore;

At (1, 4), y' = (5 × 4 - 4)/(2 × 4 - 5 × 1) = 16/3

The equation of the tangent is therefore;

y - 4 = (16/3)·(x - 1)

y = 16/3)·x - 16/3 + 4 = 16/3)·x - 4/3

The tangent at (1, 4) is; y = (16/3)·x - 4/3 = (5 1/3)·x - 1 1/3

At (1, 1), y' = (5 × 1 - 4)/(2 × 1 - 5 × 1) = 1/-3 = -1/3

The equation is therefore;

y - 1 = (-1/3)·(x - 1)

y = (-1/3)·x + 1/3 +  1 = 4/3 - (1/3)·x

The equation of a second tangent is; y = 4/3 - (1/3)·x = (1 1/3) - (1/3)·x

The null hypothesis states that there is no difference in the intensity of any discomfort experienced while counting money versus paper. Money-related groups have a M = 7.56 and SS = 42.22 mean.

The null hypothesis assumes that any differences you see between the chosen attributes in a set of data are due to chance. For instance, if the predicted profits from the gambling game genuinely equal zero, then any discrepancy between the data's average profits and zero results from chance.

Here,

According to the null hypothesis, there is no difference in how painful anything feels while counting money versus paper. The mean for the group relating to money is

=>  M = 7.56 and SS = 42.22.

=> M = 11.33 and SS = 38 for the paper group.

=> t(16) is equal to 3.57,

=> the standard error is 1.06, and the pooled variance is 5.01.

=>The critical values for df = 16 are 2.921.
