Answer:

Step-by-step explanation:

180 *8  = 1440

1440 * 5 ( monday to friday ) = 7200

7200 * 4(weeks) = 28800

extra hours

2(180 * 6)

= 1080 * 2

=2160

from the question, she gets paid 1 and a half more for extra hours

2160 * 1.5 = 3240

28,800 + 3240 = 32040

The total amount earned this month including the amount earned overtime is R32,040

Total hours worked in a week = 8 × 5

= 40 hours

Total hours worked in a month = 40 × 4

= 160 hours.

Regular amount earned in a month = 160 hours × 180

= R 28,800

= 2(1080) × 1.5

= 2,160 × 1.5

= R 3,240

Total earned for the month = R 28,800 + R 3,240

= R32,040

Anderson should use a two-sample t-test to determine if there is a statistically significant difference in annual income between college graduates and non-college graduates.

A two-sample t-test is a type of inferential statistic used to compare the means of two independent groups. It is used to determine if the difference between the two groups is statistically significant.

In this case, Anderson would compare the mean annual income of college graduates to the mean annual income of non-college graduates. If the difference between the two means is statistically significant, then Anderson can conclude that there is a difference in annual income between college graduates and non-college graduates.

If the difference is not statistically significant, then Anderson can conclude that there is no difference in annual income between the two groups.

The statement is false because with the conditions, graph of polynomial function is curve with both ends pointing upwards, positive y-intercept indicates that at least part of curve lies above x-axis. Correct answer is C.

A polynomial function of even degree with a negative leading coefficient will have its end behavior determined by the degree and parity of the polynomial. For even-degree polynomials with a negative leading coefficient, both ends of the graph will point upwards.

The positive y-value for the y-intercept indicates that the polynomial function has at least part of the curve lying above the x-axis.

Since the graph of the polynomial function does not intersect the x-axis, it means that there are no real zeros. The statement incorrectly assumes that the positive y-intercept and negative leading coefficient guarantee the existence of at least two real zeros.

So, the correct option is C.

The midsegment linking the cartesian coordinates of two of a triangle's sides is parallel to the fourth aspect of the triangle, and its length is half that of the third side, according to the midsegment theorem.

The assertions that the Greek mathematician Pythagoras discovered the properties of right-angled triangles in the fifth century BC just did not match up, according to many. Some people think following commentary shows it was a joint effort among his disciples, the Pythagoreans.

Equilateral: equal angles and all three sides. Acute isosceles: two identical sides and angles, both of which are only about 90 degrees. Acute scalene has irregular sides and angles, all of which are under 90 degrees. Obtuse isosceles: two identical sides and angles, one of which is more than 90 degrees.

According to the solving the lenght of line segment is TU = 12.

An  portion of a line with two endpoints is referred to as a line segment. A line segment, unlike a line, has a definite length.

Because T is on the line segment SU. so, addition of ST and TU must be equal to SU

SU = ST + TU..........(1)

SU = 3x -7

TU = x -1

ST = x + 7

Substituting these values into equation (1)

3x-7 = x +7 + x -1

3x -7 = 2x + 6

x = 13

For the numerical length of TU

TU = x - 1

TU = 13 - 1

TU = 12

Therefore, the degree of the resulting polynomial is m + n when two polynomials of degree m and n are multiplied together.

What is polynomial?

A polynomial is a mathematical expression consisting of variables and coefficients, which involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents. Polynomials can have one or more variables and can be of different degrees, which is the highest power of the variable in the polynomial.

Here,

When two polynomials are multiplied, the degree of the resulting polynomial is the sum of the degrees of the original polynomials. In other words, if the degree of the first polynomial is m and the degree of the second polynomial is n, then the degree of their product is m + n.

This can be understood by looking at the product of two terms in each polynomial. Each term in the first polynomial will multiply each term in the second polynomial, so the degree of the resulting term will be the sum of the degrees of the two terms. Since each term in each polynomial has a degree equal to the degree of the polynomial itself, the degree of the resulting term will be the sum of the degrees of the two polynomials, which is m + n.

The pooled proportion is 0.590. If the p-value is less than α (commonly 0.05), we reject the null hypothesis. Otherwise, if the p-value is greater than or equal to α, we fail to reject the null hypothesis.

(a) To find the relevant sample proportions in each group and the pooled proportion, we divide the number of individuals who voted by the respective sample sizes.

In Group 1, 45 out of a random sample of 70 voted, so the sample proportion is 45/70 = 0.643 (rounded to three decimal places).

In Group 2, 56 out of a random sample of 101 voted, so the sample proportion is 56/101 = 0.554 (rounded to three decimal places).

The pooled proportion is calculated by combining the total number of individuals who voted from both groups and dividing it by the total sample size. The total number of voters is 45 + 56 = 101, and the total sample size is 70 + 101 = 171. Therefore, the pooled proportion is 101/171 = 0.590 (rounded to three decimal places).

(c) To test whether there is a difference between the two groups in the proportion who voted, we can use the two-proportion z-test. The test statistic is calculated using the sample proportions and the pooled proportion.

The test statistic for the two-proportion z-test is given by the formula:

\[z = \frac{(p_1 - p_2)}{\sqrt{\hat{p}(1 - \hat{p})(\frac{1}{n_1} + \frac{1}{n_2})}}\]

where \(p_1\) and \(p_2\) are the sample proportions, \(\hat{p}\) is the pooled proportion, and \(n_1\) and \(n_2\) are the sample sizes of each group.

Substituting the values, we have:

\[z = \frac{(0.643 - 0.554)}{\sqrt{0.590(1 - 0.590)(\frac{1}{70} + \frac{1}{101})}}\]

Calculating the above expression gives us the test statistic. Round the answer to two decimal places.

To obtain the p-value, we compare the test statistic to the standard normal distribution. The p-value represents the probability of obtaining a test statistic as extreme as the observed one, assuming the null hypothesis is true.

Once we have the test statistic, we can consult the standard normal distribution table or use statistical software to determine the corresponding p-value.

The conclusion of the hypothesis test is typically based on the significance level (α) chosen. If the p-value is less than α (commonly 0.05), we reject the null hypothesis. Otherwise, if the p-value is greater than or equal to α, we fail to reject the null hypothesis.

Please provide the calculated values for the test statistic and p-value, and I can assist you in drawing the conclusion.

The tangent ratio is used to solve for a missing angle in a right triangle by dividing the length of the side opposite the angle by the length of the side adjacent to the angle.

Using the tangent ratio, we can find a missing angle in a right triangle by taking the inverse tangent (arctan) of the ratio. For example, if we know the length of the side opposite an angle and the length of the side adjacent to the angle, we can use the tangent ratio to find the value of the angle.

Using the cotangent ratio, we can also find a missing angle in a right triangle by taking the inverse cotangent (arccot) of the ratio. If we know the length of the side adjacent to an angle and the length of the side opposite the angle, we can use the cotangent ratio to find the value of the angle.

The main difference between using the tangent ratio and the cotangent ratio is the order of the sides in the ratio. The tangent ratio involves the opposite side divided by the adjacent side, while the cotangent ratio involves the adjacent side divided by the opposite side.

Both the tangent and cotangent ratios are useful tools for solving right triangles and finding missing angles. The choice between using one or the other depends on the given information and the specific problem at hand.

The maximum profit if the profits per acre are $75 for corn and $40 for soybeans is $371,255.83. Therefore, the correct option is c.

To find the maximum profit from planting corn and soybeans, we can use linear programming. Let's first define the variables and write the constraints.

Let x be the number of acres of corn and y be the number of acres of soybeans.

1. Total acre constraint: x + y ≤ 6,000

2. Fertilizer/herbicide constraint: 9x + 3y ≤ 40,501

3. Labor constraint: 0.75x + y ≤ 5,250

The objective function to maximize is the profit function: P(x,y) = 75x + 40y

Now, we will use the Solver to find the maximum profit:

Step 1: Set up a spreadsheet with the constraints and the objective function.

Step 2: Go to the Data tab and click on Solver. If Solver is not available, you may need to add it in Excel Options.

Step 3: Set the objective function by selecting the cell with the profit function.

Step 4: Choose "Max" for the objective.

Step 5: Add the constraints by selecting the corresponding cells.

Step 6: Click on "Solve" and the Solver will find the optimal values for x and y.

After using Solver, we find that the optimal values are x = 4,363.89 (corn) and y = 1,636.11 (soybeans), which yields a maximum profit of $371,255.83. Therefore, the correct answer is c: $371,255.83

The ratio of the perimeters is 8:3 and the ratio of the area of the shaded to the non-shaded is 64 : 9 .

We know that when two figures are similar then the ratio of all the corresponding sides of the two figures are the same.

1) Given the ratio of the sides of shaded : non-shaded = 8 : 3

Therefore the perimeter of the shaded figure : perimeter of non shaded rectangle= 8 : 3

Again ratio of areas =  ratio of the square of corresponding sides.

Area of shaded : area of non -shaded = 8² : 3² = 64 : 9

2) ratio of perimeter of shaded to non shaded trapezium

ratio = 6 : 10 = 3: 5

ratio of areas = 3² : 5² = 9 : 25
