To consider the results of the 15 experiments valid, they should be similar in at least 8 of the trials . So, option C is the right choice.

To determine the number of times the results should be similar for them to be considered valid, we need to establish a threshold based on the number of experiments conducted. In this case, the experiment was repeated 15 times.

To determine the minimum number of times the results should be similar for validity, we can calculate the majority. We divide the total number of trials by 2 and add 1. In this case, 15 divided by 2 equals 7.5, and adding 1 gives us 8.

Therefore, for the results to be considered valid, they should be similar in at least 8 out of the 15 trials. This threshold ensures that the majority of the experiments produced consistent results, indicating reliability and reproducibility.

Thus, The correct answer is option C.8

Answer:

To find a 90 percent confidence interval for the population mean of the workers' monthly income in the factory, you can use the formula:

Confidence interval = sample mean ± (critical value * standard error)

First, you need to find the critical value corresponding to a 90 percent confidence level. Since the sample size is large (n = 100), we can use the Z-distribution. For a 90 percent confidence level, the critical value is approximately 1.645.

Next, you calculate the standard error, which is the standard deviation of the sample divided by the square root of the sample size:

Standard error = standard deviation / √(sample size)

Standard error = 20 / √(100)

Standard error = 20 / 10

Standard error = 2

Now you can substitute the values into the confidence interval formula:

Confidence interval = 400 ± (1.645 * 2)

Calculating the confidence interval:

Lower bound = 400 - (1.645 * 2) = 400 - 3.29 = 396.71

Upper bound = 400 + (1.645 * 2) = 400 + 3.29 = 403.29

The 90 percent confidence interval for the population mean of the workers' monthly income is approximately 396.71 to 403.29 birr.

Explanation:

Interpretation: We are 90 percent confident that the true population mean of the workers' monthly income in the factory falls within the range of 396.71 to 403.29 birr. This means that if you were to take multiple samples and calculate confidence intervals for each sample, approximately 90 percent of those intervals would contain the true population mean.

Answer:

10,240 tires

Explanation:

To calculate the percentage of tires that are expected to last for between 45,000 and 55,000 miles, we need to find P(45000 < X < 55000).

Calculator input for "normal cumulative distribution function (cdf)":

⇒ P = 0.682689492...

⇒ P = 68.27%

Therefore, approximately 68.27% (2 d.p.) of tires are expected to last for between 45,000 and 55,000 miles.

To find the number of tires that are expected to last between 45,000 and 55,000 miles from a random sample of 15,000, multiply the found percentage by the number in the sample:

⇒ 0.682689492... × 15000 = 10240.3428...

Therefore, of a random sample of 15,000 tires, 10,240 tires are expected to last for between 45,000 and 55,000 miles.

Answer:

To find the 95% confidence interval for the true mean breaking strength of all cables produced by the manufacturer, we can use the formula:

Confidence Interval = Sample Mean ± (Critical Value * Standard Error)

First, let's calculate the standard error, which is the standard deviation divided by the square root of the sample size:

Standard Error = Standard Deviation / √(Sample Size)

= 92 / √(90)

≈ 9.685

Next, we need to determine the critical value corresponding to a 95% confidence level. Since the sample size is large (n > 30), we can use the z-table. The z-value for a 95% confidence level is approximately 1.96.

Now we can calculate the confidence interval:

Confidence Interval = Sample Mean ± (Critical Value * Standard Error)

= 1700 ± (1.96 * 9.685)

Lower Limit = 1700 - (1.96 * 9.685)

≈ 1679.69

Upper Limit = 1700 + (1.96 * 9.685)

≈ 1720.31

Therefore, the 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer is approximately (1679.7, 1720.3). The lower limit is 1679.7 pounds, and the upper limit is 1720.3 pounds.

Answer:

The area of ΔABC = 25 (E)

Explanation:

⭐What is the formula for the area of a triangle?

If AB = BC, then BC = \(5\sqrt{2}\).

If BC = \(5\sqrt{2}\), then ∠A = 45°.

Utilize the triangle sum theorem to solve for ∠B.

⭐What is the triangle sum theorem?

∠A + ∠B + ∠C = 180

45 + ∠B + 45 = 180

90 + ∠B = 180

∴ ∠B = 90

This means that ΔABC is a right triangle.

If ΔABC is a right triangle, then BC is the height of the triangle, because it is the altitude that forms a 90 degree angle.

If ΔABC, then AB is the base of the triangle.

Thus, we need to solve for BC, substitute it into the area formula, and solve for the area.

To find an unknown side length, we use trigonometric functions.

⭐What are trigonometric functions?

⭐What are the types of trigonometric functions?

To determine which trigonometric function we use, we need to see the type of side lengths we are given (adjacent, opposite, or hypotenuse).

We are given side length AB, which is adjacent to ∠A.

We want to find side length BC, which is opposite of ∠A.

∠A = 45 degrees.

Therefore, we will use tan(θ).

Substitute the values of the side lengths and angle measure into tan(θ):

\(tan(x) = \frac{opposite}{adjacent}\)

\(tan(45) = \frac{BC}{5\sqrt{2}}\)

Compute using the trigonometric table (i attached it to this response):

\(tan(45) = \frac{BC}{5\sqrt{2}}\)

\(1 = \frac{BC}{5\sqrt{2}}\)

\(5\sqrt{2} = BC\)

∴ BC, the height, = \(5\sqrt{2}\)

Substitute the values of the base and the height into the area formula, and solve for the area:

\(area = \frac{1}{2}(bh)\)

\(area = \frac{1}{2}(5\sqrt{2}*5\sqrt{2})\)

\(area = \frac{1}{2}(50)\)

\(area = 25\)

∴ The area of ΔABC = 25

Monterey Bay, on the California coast, contains a diverse and complex ecological community. A variety of seaweeds and single-celled algae make up the base of the food web. Many animals, such as sea urchins, abalone, snails, and crabs, graze on these photosynthetic organisms. Otters and small fish eat all of these primary consumers, and in turn, are eaten by orcas and sharks. Orcas eat many other smaller organisms, including dolphins, sea lions, harbor seals, and many kinds of fish. Sea stars prey on sea urchins, abalone, and snails, whereas octopuses eat crabs, fish, and sea stars. Sea lions and harbor seals eat predominantly fish. Sea cucumbers eat dead organic matter that falls to the sea floor. Place each of the organisms in the trophic pyramid based on where it gets its energy. Each organism will be used only once, even if some of the organisms consume organisms from several trophic levels.
