Answers
Therefore, the reliability of the results may be questioned due to the small sample size and the fact that the observed and expected counts in some cells are too small.
The fact that two of the six observed counts are 5 or less should make you the most worried about the reliability of the results of the test in this case. This is because when the observed counts in a cell are too small, it is difficult to draw reliable conclusions from them. In such cases, the chi-squared statistic may not accurately reflect the true relationship between the variables being studied. This is because the chi-squared statistic is based on the difference between the observed counts and the expected counts, and if the observed counts are too small, the chi-squared statistic may be biased and not accurately reflect the true relationship between the variables.
Moreover, the fact that two of the six expected counts are less than 5 also raises concerns about the reliability of the results. This is because when the expected counts in a cell are too small, it may indicate that the sample size is too small or that the sample is not representative of the population being studied. In this case, the sample size was only 300 black women, which may not be representative of all black women.

can you make two triangles that are not congruent that have three pairs of congruent angles?
Answers
if two triangles have three pairs of congruent angles, then they must be congruent to each other by the Angle-Angle-Angle (AAA) congruence theorem, and thus cannot be non-congruent.
No, it is not possible to make two triangles that are not congruent and have three pairs of congruent angles. This is because if two angles of a triangle are congruent, then the third angle must also be congruent by the Angle Sum Theorem, which states that the sum of the angles in a triangle is always 180 degrees. If two triangles have three pairs of congruent angles, then all three angles in each triangle are congruent, meaning they have the same measure. However, this does not guarantee that the sides of the triangles are congruent. In order for two triangles to be congruent, they must have the same angle measures as well as the same side lengths. Therefore, if two triangles have three pairs of congruent angles, then they must be congruent to each other by the Angle-Angle-Angle (AAA) congruence theorem, and thus cannot be non-congruent.

yesterday, 28 students took a test. the arithmetic mean of those 28 scores was 72 points. two students who were absent yesterday took the test this morning, and the arithmetic mean of all 30 test scores is 73 points. if the difference of the two scores from this morning is 22 points, what is the lower score from this morning?
Answers
Let's assume the sum of the scores of the 28 students who took the test yesterday is 28 * 72 = 2016.
We know that the sum of the scores of all 30 students is (28 * 72) + x + y, where x and y are the scores of the two students who took the test this morning.
We also know that the mean of all 30 scores is 73. So we can write an equation:
[(28 * 72) + x + y]/30 = 73
Multiplying both sides by 30, we get:
2016 + x + y = 2190
So, x + y = 174.
We are given that the difference of the two scores is 22, so we can write another equation:
y - x = 22
Solving these two equations simultaneously, we get y = 98 and x = 76.
Therefore, the lower score from this morning is 76.

Suriland cannot both export wheat and keep bread plentiful and affordable in Suriland. Accordingly, Suriland's wheat farmers are required to sell their crop to the government, which pays them a dollar per bushel less than the price on the world market. Therefore, if the farmers could sell their wheat on the world market, they would make a dollar per bushel more, less any additional transportation and brokerage costs they would have to pay.
Which of the following, if true, most seriously weakens the argument?
(A) Suriland's wheat farmers have higher production costs than do farmers in many other wheat-producing countries.
(B) Sale of a substantial proportion of Suriland's wheat crop on the world market would probably depress the price of wheat.
(C) The transportation and brokerage costs that Suriland's farmers would face if they sold their wheat outside Suriland could amount to almost a dollar per bushel.
(D) Suriland is surrounded by countries that do not import any wheat.
(E) The price of a bushel of wheat on the world market occasionally drops below the average cost of producing a bushel of wheat in Suriland.
Answers
Answer:
the most accurate argument is (C) The transportation and brokerage costs that Suriland's farmers would face if they sold their wheat outside Suriland could amount to almost a dollar per bushel.
Step-by-step explanation:
The cost of transportation and other logistics is being covered by the government that is why the government pay less than dollar per bushel.
so the price of the wheat would have to decrease at home so that the cost of the transportation can be covered by the government who are buying directly from the farmers.

a. 5.90%
b. 3.08%
c. 5.85%
d. 2.95%

Answers
We need to find the current yield of a bond that pays interest semiannually, given that the bond's price is $958.56, the semiannual coupon payment is $29.50, and the par value is $1,000. Therefore, the answer is option (e) 6.16%.
The formula for current yield is given by (Annual Interest Payment / Current Market Price) * 100.
The bond that pays interest semiannually has a price of $958.56 and a semiannual coupon payment of $29.50.
If the par value is $1,000, what is the current yield?
Solution: Given, Price of the bond = $958.56
Semi-annual coupon payment = $29.50
The par value of the bond = $1000
The coupon rate per period is calculated as follows:
Coupon rate = Semi-annual coupon payment / Par value of the bond
Coupon rate = $29.50 / $1000Coupon rate = 0.0295
The current yield is calculated as follows:
Current yield = (Annual Interest Payment / Current Market Price) * 100
Since the bond pays interest semiannually, the annual interest payment is:
Annual Interest Payment = Semi-annual coupon payment * 2
Annual Interest Payment = $29.50 * 2
Annual Interest Payment = $59
The current market price of the bond is $958.56
Therefore, Current yield = (Annual Interest Payment / Current Market Price) * 100
Current yield = ($59 / $958.56) * 100
Current yield = 6.16%.

Samantha’s normal wage is R300 per hour and her normal working day is 8 hours. The standard production time for each employee is 4 units for every 30 minutes. On 17 March 2022, Samantha’s production was 76 units. Using the Halsey bonus system, a bonus of 50% of the time saved is given to employees.
Answers
Samantha’s remuneration for 17 March 2022 is R2475.
To calculate Samantha’s remuneration for 17 March 2022, we need to find the time saved by her using the Halsey bonus system.
Step-by-step explanation:
As per the given data,
Samantha’s normal wage is R300 per hour and her normal working day is 8 hours.
Thus, Samantha’s normal wage for a day = R300 × 8 = R2400.
The standard production time for each employee is 4 units for every 30 minutes.
Therefore, Production time for Samantha = 76 units
Time taken to produce 4 units = 30 minutes
Time taken to produce 76 units = (30/4) × 76 minutes
= 570 minutes (9.5 hours)
Therefore, Samantha took 9.5 hours to produce 76 units.
Using the Halsey bonus system, a bonus of 50% of the time saved is given to employees.
So, time saved = 9.5 − (76/4 × 0.5)
= 9.5 − 9
= 0.5 hours
= 30 minutes.
Remuneration for the day will be:
Samantha’s normal wage for a day + Bonus
Normal wage for 0.5 hour = 300 × 0.5
= R150
Bonus = 50% of time saved
= 50% of R150
= R75
Therefore, Remuneration for Samantha for 17 March 2022 = R2400 + R75
= R2475.

how to calculate temperature of earth 3 billion years ago with albedo?
Answers
To calculate the temperature of the Earth 3 billion years ago with albedo, we need to first determine the albedo at that time. This can be done by analyzing various geological and chemical data, such as the composition of rocks and sediments, the presence of specific minerals and isotopes, and the amount of atmospheric gases and aerosols.
Once the albedo is estimated, we can use the Stefan-Boltzmann law, which relates the temperature of a body to its radiative energy emission, to determine the equilibrium temperature of the Earth. The Stefan-Boltzmann law states that the radiative energy emission of a body is proportional to the fourth power of its absolute temperature.
Assuming that the Earth was in radiative equilibrium with the Sun, we can use the following formula to calculate the temperature of the Earth:
T = (S (1 - A) / 4 σ)^(1/4)
where T is the temperature of the Earth, S is the solar constant (the amount of solar radiation received by the Earth), A is the albedo, and σ is the Stefan-Boltzmann constant.
By plugging in the values for S, A, and σ, we can calculate the temperature of the Earth at that time. However, it's important to note that there are many uncertainties and assumptions involved in this calculation, and the estimated temperature should be taken as an approximation.
The temperature of the Earth in the past can be estimated using various geological and climatological data. One important factor that can help in determining the temperature is the Earth's albedo, which is the proportion of solar radiation reflected by the Earth's surface and atmosphere. The albedo can affect the amount of energy the Earth receives from the Sun, which can impact the temperature.

statistical power is a measure of the ability to reject the null hypothesis when:
Answers
Statistical power is a measure of the ability to reject the null hypothesis when it is false. It represents the probability of correctly identifying a true effect or relationship in a statistical hypothesis test.
A high statistical power indicates a greater likelihood of detecting a significant result if the null hypothesis is indeed incorrect. The power of a statistical test depends on several factors, including the sample size, the effect size (the magnitude of the true effect or difference), the chosen significance level (often denoted as α), and the variability or noise in the data. Increasing the sample size or effect size generally increases the statistical power, while a lower significance level or higher variability decreases it.
Power analysis is commonly used to determine an appropriate sample size for a study, ensuring that it is adequately powered to detect the desired effect. A higher power is desirable as it reduces the chances of a Type II error (failing to reject the null hypothesis when it is false) and increases the chances of correctly detecting real effects or relationships.
