Top Left: Acute Top Right: Acute Bottom Right: Obtuse Bottom Left: Right

Step-by-step explanation:

The top left and right have all angles less than 90 degrees which makes them acute. The Bottom right has an angle over 90 degrees which makes it obtuse, and the last one has a right angle 90 degrees.

The dimensions of the rectangular box are length (L), width (W), and height (H). The radius of the sphere inscribing the rectangular box is 8.

Let's assume the dimensions of the rectangular box are length (L), width (W), and height (H). Since the box is inscribed in a sphere, its longest diagonal will be equal to the diameter of the sphere, which is 2r (r is the radius of the sphere).

The surface area of the rectangular box can be calculated by summing the areas of its six faces: 2(LW + LH + WH) = 384.

The sum of the lengths of the 12 edges of the box is given as 4(L + W + H) = 112.

From these equations, we can solve for L + W + H = 28.

To find the radius of the inscribing sphere, we need to find the longest diagonal of the rectangular box. Using the Pythagorean theorem, the longest diagonal is √(L^2 + W^2 + H^2).

Since we have L + W + H = 28, we can substitute L + W = 28 - H into the equation for the longest diagonal: √((28 - H)^2 + H^2) = 2r.

By solving this equation, we find that H = 8.

Substituting this value into the equation L + W + H = 28, we get L + W = 20.

Finally, substituting L + W = 20 into the equation for the longest diagonal, we find √(20^2 + 8^2) = 2r.

Simplifying, we find r = 8.

Therefore, the radius of the sphere inscribing the rectangular box is 8.

The store should have 445 picks remaining, not 450 as estimated by the manager. To determine if the store manager's estimate is reasonable, let's analyze the situation.

The store initially has 500 guitar picks. They order 15 boxes, and each box contains 9 picks. So the total number of picks they receive from the order is:

15 boxes * 9 picks/box = 135 picks

Next, the store sells 19 boxes, with each box containing 10 picks. Therefore, the total number of picks sold is:

19 boxes * 10 picks/box = 190 picks

To find the remaining number of picks, we can subtract the sold picks from the received picks:

Total remaining picks = Initial picks + Received picks - Sold picks

Total remaining picks = 500 + 135 - 190 = 445 picks

According to the calculations, the store should have 445 picks remaining, not 450 as estimated by the manager.

However, it's important to note that we are working with whole numbers, so there might be some rounding involved in the manager's estimate. It's possible that the manager rounded up to 450 for simplicity or other reasons.

Given the small discrepancy of 5 picks between the calculated value and the manager's estimate, it is reasonable to conclude that the manager's estimate is close enough to the actual number of picks. The discrepancy could be due to rounding or a small counting error. It's unlikely to have a significant impact on the store's operations or inventory management.

In summary, while the manager's estimate of 450 guitar picks may not be exactly accurate, it is reasonably close to the actual remaining number of picks based on the given information.

To test your hypothesis, you would use the One Sample T test. This test is appropriate for comparing the mean of a single sample to a known value, which in this case is 47.

The T test: two sample assuming unequal variances and T test: two sample assuming equal variances are used to compare the means of two independent samples, while the T test: paired two sample for means is used to compare the means of two related samples. None of these tests would be suitable for testing your hypothesis about the average age of customers who buy BMX bicycles.
To test the hypothesis that the average age of customers who buy BMX bicycles is greater than 47, you should use the "One Sample T-test."
The One Sample T-test is appropriate in this scenario because you are comparing the average age of customers to a specific value (47) rather than comparing two different groups of customers. The other T-test options, such as two-sample T-tests and paired two-sample T-tests, are not suitable as they involve comparing two separate groups or pairs of related data.

Mario's new credit balance including interest is $2579.63

Given,

Mario's current credit balance = $2,109.65

Minimum payment amount = $68.00

The amount Mario plans to spend over the next month = $471.00

APR = 31.99%

We have to find the new balance including interest.

Monthly interest rate on credit card = APR/12 = (31.99%/12)

The credit balance before interest = (current balance) + (expense for next month) - (minimum payment)

= 2109.65 + 471 - 68

= $2512.65

The credit balance after interest = 2512.65 ×   (1 + 0.3199/12) = $2579.63

Yes, the given statement is true that the measure of angle 1 is equal to the measure of angle 2 as Option a. they both intercept the same arc on the circle.

Applying the inscribed angle theorem represents that the measure of ∠1 is equal to the measure of ∠2

Inscribed angle theorem  states that an angle formed by two chords which intersect on a circle is equal to half the measure of the intercepted arc.

Measure of an angle is not determined by the factor that the length of the sides of an angle .

Here it is irrelevant the fact that the sides of ∠2 are longer than those of ∠1.

This is also a irrelevant factor that they intercept the circle at different points .

Because position of the points on the circle do not determined the measure of the inscribed angle.

It is the measure of the intercepted arc that determines the measure of the inscribed angle.

Therefore, the measure of angle1 is equal to the measure of ∠2 is the only relevant factor given by option a. they intercept the same arc.

a. yes, because they intercept the same arc.

Answer:

I believe it is reflection

Step-by-step explanation:

So the acute angle of the rhombus is 90 degrees, and the obtuse angle is twice as large, or 180 degrees.

The Pythagorean theorem is a fundamental concept in geometry that describes the relationship between the sides of a right triangle. It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

Let's start by finding the length of one half of the longer diagonal. We can use the shorter diagonal (which we know is 10 cm) and the side length (which we know is 13 cm) to form a right triangle. The hypotenuse of this triangle is half of the longer diagonal, so we can solve for it using the Pythagorean theorem:

\(a^2+b^2 = c^2 \\(13/2)^2 + 10^2 = c^2\\169/4+100 =c^2 \\ 269/4= c^2 \\c = \sqrt{(269)}/2\\\)

Therefore, the length of one half of the longer diagonal is sqrt(269)/2 cm. To find the full length of the longer diagonal, we just need to double this value:

longer diagonal = \(2 \times \sqrt{(269)}/2 = \sqrt{(269)}cm\)

Now, we can use the fact that the sum of the angles in a rhombus is 360 degrees to solve for x:

2x + 2x = 360

4x = 360

x = 90

If the utilization of an M/M/1 model is 0.6, the c of time there is at least one person in the system is 100%.

In an M/M/1 model, the utilization represents the ratio of the arrival rate (λ) to the service rate (μ). If the utilization is less than 1, it means that the arrival rate is lower than the service rate, and the system is not fully utilized. However, even with a utilization of 0.6, there will still be instances where there is at least one person in the system. This is because the arrival rate is not zero, indicating that customers are still arriving, albeit at a lower rate compared to the service rate. Therefore, the percentage of time with at least one person in the system would be 100%. If you are told that the utilization rate for an M/M/1 model is 0.8 and the average number of people in the system is 4, it is impossible to determine the average number of people in the queue without further information. The average number of people in the queue depends on factors such as the arrival rate and service rate, which are not provided in this scenario. The utilization rate alone and the average number of people in the system do not provide sufficient information to calculate the average number of people in the queue accurately. Therefore, it is impossible to determine the average number of people in the queue based solely on the given information.

(b) Sofie can select a simple random sample of students by using a random number generator to assign a unique identification number to each student in the online high school.

(c) The sample for Sofie's research is the 32 completed surveys she received. These surveys represent the responses of a subset of the population. The population, in this case, refers to all the students at the online high school.

(d) If Sofie uses only the completed surveys, she can conclude that approximately 50% (16 out of 32) of the students who completed the survey reported using social media while doing schoolwork.

(a) Please select one of the following options: never, rarely, occasionally, frequently, or always."

(b) She can then use the random number generator again to select a specific number of students from the entire population of students, ensuring that each student has an equal chance of being selected. For example, if there are 500 students in total and Sofie wants a sample size of 50, she can generate 50 random numbers and select the corresponding students based on their identification numbers.

(d) However, it is important to note that this conclusion is specific to the sample of completed surveys and cannot be generalized to the entire population of high school students.

To make an inference about the percent of all high school students who use social media while doing schoolwork, Sofie would need a larger and more representative sample that covers a wider range of students in the online high school.
