I Dont Know What To Write Here The Question Is There

Answers

Answer 1

Answer:

53.93 cm

Step-by-step explanation:

The given arc is 38.95 and the angle is 260 degrees.

A full angle would be 360 degrees, so we can use a ratio to find what the full circle would be:  

260/360 = 38.95/x

This equation is saying that 38.95 is equal to 260 degrees of the circle, while x is equal to 360 degrees.

Solving for x:

260x = 14022

x = 53.9306792

Round and it is:

53.93 cm

The manager of a fast-food restaurant determines that the average time that her customers wait for service is 3 minutes. Find the probability that a customer has to wait more than 4 minutes.

Answers

To find the probability that a customer has to wait more than 4 minutes, we need to use the normal distribution and standard deviation.

If the manager knows the standard deviation, we can use it to calculate the z-score and find the probability using a standard normal distribution table. However, since the standard deviation is not given in this question, we will assume that the distribution of waiting times is approximately normal and use the empirical rule.
The empirical rule states that for a normal distribution, approximately 68% of the values lie within one standard deviation of the mean, approximately 95% lie within two standard deviations, and approximately 99.7% lie within three standard deviations.
Since the average time that customers wait is 3 minutes, and we want to find the probability that a customer waits more than 4 minutes, we need to calculate how many standard deviations away from the mean 4 minutes is.
z = (x - μ) / σ
where x = 4, μ = 3, and σ is the standard deviation. Since we don't know the value of σ, we can't calculate the z-score directly. However, we can make a reasonable assumption that the standard deviation is around 1 minute. This is based on the empirical rule which states that approximately 68% of the values lie within one standard deviation of the mean.
So, σ = 1 minute, and
z = (4 - 3) / 1 = 1
Now we can use a standard normal distribution table to find the probability of a z-score of 1 or greater. From the table, we can see that the probability of a z-score of 1 or greater is approximately 0.1587.
Therefore, the probability that a customer has to wait more than 4 minutes is approximately 0.1587 or 15.87%.

To find the probability that a customer at the fast-food restaurant has to wait more than 4 minutes, we'll use the exponential distribution.
1. First, let's find the rate parameter, which is the reciprocal of the average waiting time: λ = 1 / average waiting time. In this case, λ = 1 / 3 ≈ 0.3333.
2. Now, we'll use the cumulative distribution function (CDF) of the exponential distribution to find the probability of waiting less than or equal to 4 minutes: P(X ≤ 4) = 1 - e^(-λx) = 1 - e^(-0.3333 × 4) ≈ 0.7364.
3. To find the probability of waiting more than 4 minutes, subtract the CDF value from 1: P(X > 4) = 1 - P(X ≤ 4) = 1 - 0.7364 ≈ 0.2636.
So, the probability that a customer at the fast-food restaurant has to wait more than 4 minutes is approximately 0.2636 or 26.36%.

You are using 100 college students to find out how hours of revision affect their performance in a college-level spanish language exam. what variables could be a confounding variable for your study?

Answers

A confounding variable is a variable that is related to both the independent variable (hours of revision) and the dependent variable (performance in a college-level Spanish language exam).

In this study, potential confounding variables could include the students' prior knowledge of Spanish, their natural ability in language learning, their level of motivation, their access to study resources, and their level of stress or anxiety. These factors could impact both the amount of time a student spends revising and their performance on the exam, making it difficult to determine if the hours of revision directly caused any changes in exam performance. To control for these confounding variables, researchers may consider randomly assigning students to different revision time groups, measuring these other factors, or using statistical analysis techniques to adjust for these variables.
In your study on the effect of revision hours on college-level Spanish language exam performance among 100 college students, potential confounding variables could include:

1. Prior knowledge of Spanish: Students with previous experience in learning Spanish may perform better than those without, regardless of revision hours.
2. Study habits: The quality of study methods can influence the effectiveness of revision hours.
3. Language aptitude: Some students may naturally possess a higher aptitude for language learning, affecting their exam performance.
4. Instructor quality: The effectiveness of the Spanish language instructor can influence student performance.
5. Sleep and stress levels: Adequate sleep and low stress levels can improve a student's ability to retain information during revision.

Talia claims that
the surface area of the cylinder is about 2,285.92
square centimeters. Explain Talia's error. Find the
correct surface area of the cylinder using the picture below.

Answers

The correct surface area of the cylinder is  878.06 sq. cm.

From the net of the cylinder we have the diameter of the circular bases of the cylinder.

So, the radius of the circle would be,

r = 13/2

Using the formula for area of circle the surface area of two circular bases would be,

A₁ = 2 × π × r²

A₁ = 2 × π × (13/2)²

A₁ = π × 169/2

A₁ = 265.46 sq. cm.

The length of the rectangle would be equal to the circumference of the circle.

So, the length of the rectangle would be,

l = 2× π × r

l = 2× π × (13/2)

l = 13 × π

l = 40.84 cm

Using the formula for the area of rectangle,

A₂ = l × w

A₂ = 40.84 × 15

A₂ = 612.6 sq. cm.

So, the total surface area of the cylinder would be,

A = A₁ + A₂

A = 265.46 +  612.6

A = 878.06 sq. cm.

This means that the surface area claimed by Talia is incorrect.

Therefore, the correct surface area of the cylinder =  878.06 sq. cm.

According to the Empirical Rule. Find specified probability. (Round to FOUR decimal places. Write like 0.1234). P(z<-3.14)

Answers

Using a z-table or calculator, we can find that the probability of getting a z-score less than -3.14 is approximately 0.0008 (rounded to four decimal places as requested).

Using the Empirical Rule and the concept of probability, I can help you find the requested probability. The Empirical Rule, also known as the 68-95-99.7 rule, states that for a normal distribution:

- Approximately 68% of the data falls within 1 standard deviation (SD) of the mean
- Approximately 95% of the data falls within 2 SDs of the mean
- Approximately 99.7% of the data falls within 3 SDs of the mean

You are asked to find the probability P(z < -3.14). Since -3.14 is slightly beyond -3 SDs from the mean, we know that less than 0.15% of the data falls in that area, as 99.7% of the data is within ±3 SDs.

However, to get a more precise probability, we need to use a standard normal (Z) table or calculator. When looking up z = -3.14, we find that the probability P(z < -3.14) is approximately 0.0008.

So, the probability you are looking for is 0.0008.

The owner of the Good Deals Store opens a new store across town. For the new store, the owner estimates that, during business hours, an average of 90 shoppers per hour enter the store and each of them stays an average of 12 minutes. If the average number of shoppers in the original store at any time was 45, then the average number of shoppers in the new store at any time is what percent less than the average number of shoppers in the original store at any time?
A. 60
B. 70
C. 80
D. 50

Answers

To solve this problem, we need to first find the average number of shoppers in the new store at any time.

We know that during business hours, 90 shoppers per hour enter the store and each stays an average of 12 minutes.

To find the average number of shoppers at any time, we need to convert the time each shopper spends in the store to hours:

12 minutes = 0.2 hours

So, on average, each shopper takes up 0.2 hours in the store.

Therefore, the average number of shoppers in the new store at any time is:

90 shoppers/hour x 0.2 hours/shopper = 18 shoppers

Now we can find the percent less that the average number of shoppers in the new store is compared to the original store:

Percent less = (Original - New) / Original x 100%

Percent less = (45 - 18) / 45 x 100%

Percent less = 27 / 45 x 100%

Percent less = 60%

So the answer is A. 60.
To find the average number of shoppers in the new store at any time, we can use the formula:

Average number of shoppers at any time = (Number of shoppers per hour * Average time spent in store) / 60

For the new store:
Average number of shoppers at any time = (90 shoppers per hour * 12 minutes) / 60
Average number of shoppers at any time = 1080 / 60 = 18 shoppers

Now we will find the percentage difference between the average number of shoppers in the original store (45 shoppers) and the new store (18 shoppers):

Percentage difference = ((Original store shoppers - New store shoppers) / Original store shoppers) * 100
Percentage difference = ((45 - 18) / 45) * 100
Percentage difference = (27 / 45) * 100 = 60%

So the average number of shoppers in the new store at any time is 60% less than the average number of shoppers in the original store at any time. Your answer: A. 60

Find the differential of each function. (a) y = x2 sin 8x dy = X (b) y = 4+ dy =

Answers

For part (a), we use the product rule and chain rule of differentiation:

y = x^2 sin(8x)

dy/dx = (2x sin(8x)) + (x^2 cos(8x) * 8)

dy/dx = 2x sin(8x) + 8x^2 cos(8x)

So, the differential of y = x^2 sin(8x) is dy = (2x sin(8x) + 8x^2 cos(8x)) dx.

For part (b), the differential is simply the derivative of y with respect to x, since y is not a function of x in this case:

y = 4+

dy/dx = 0

So, the differential of y = 4+ is dy = 0 dx.

To find the differential of each function, we will use the derivative rules. Let's solve each part step-by-step:

(a) y = x^2 sin(8x)

To find the differential (dy) of this function, we will need to find the derivative of y with respect to x (dy/dx). In this case, we will use the product rule, which states that if y = uv, where u and v are functions of x, then:

dy/dx = u(dv/dx) + v(du/dx)

Let u = x^2 and v = sin(8x).

Now, we need to find du/dx and dv/dx:

du/dx = 2x (by using the power rule)
dv/dx = 8*cos(8x) (by using the chain rule)

Now apply the product rule:

dy/dx = x^2 * 8*cos(8x) + sin(8x) * 2x
dy/dx = 8x^2*cos(8x) + 2x*sin(8x)

So, the differential of the function y = x^2*sin(8x) is dy/dx = 8x^2*cos(8x) + 2x*sin(8x).

(b) y = 4

To find the differential (dy) of this function, we will find the derivative of y with respect to x (dy/dx).

Since y is a constant function (it doesn't depend on x), its derivative is simply:

dy/dx = 0

So, the differential of the function y = 4 is dy/dx = 0.

Answers

Given that P(Xi > 0), we can infer that the probability of Xi being positive has implications on the convergence properties of the sequence and the limiting constant 'a'.

Based on the information given, we can say that the probability of xi being greater than zero is positive, i.e., p(xi > 0) > 0. This means that xi has a positive probability of taking values greater than zero.

Moreover, since the sequence of random variables converges in probability to a constant a, we can say that for any ε > 0,

lim P(|xi - a| > ε) = 0

This implies that as n approaches infinity, the probability that xi deviates from a by more than ε approaches zero.

Thus, we can conclude that the sequence of random variables xi is "almost surely" bounded away from zero as n approaches infinity, and the limit of the sequence is the constant a.
. Considering a sequence of random variables X1, X2, ..., Xn that converges in probability to a constant 'a', we can say that the probability of each Xi being greater than 0, denoted as P(Xi > 0), is relevant to understanding the limiting behavior of the sequence.

As the sequence converges in probability to 'a', it means that for any given ε > 0, the probability that the absolute difference between Xi and 'a' is greater than ε approaches 0 as n approaches infinity:

lim (n→∞) P(|Xi - a| > ε) = 0

Given that P(Xi > 0), we can infer that the probability of Xi being positive has implications on the convergence properties of the sequence and the limiting constant 'a'.

The critical values of x are 31.319, 18.475, and 28.869 for each case respectively.

To find the critical values of x (x₂), we'll use the chi-square distribution table. The critical values depend on the degrees of freedom (df) and the significance level (α).

1. For n=14 and α=0.005:
  Degrees of freedom (df) = n - 1 = 14 - 1 = 13
  From the chi-square table, x₂ (13, 0.005) ≈ 31.319

2. For n=8 and α=0.01:
  Degrees of freedom (df) = n - 1 = 8 - 1 = 7
  From the chi-square table, x₂ (7, 0.01) ≈ 18.475

3. For n=18 and α=0.02:
  Degrees of freedom (df) = n - 1 = 18 - 1 = 17
  From the chi-square table, x₂ (17, 0.02) ≈ 28.869

The values of the trigonometry are as follows

8. cos x = 9/17

10. sin x = 0.8

12. cos x = 4/5

How to find the cos of angle with the given sin

From trigonometry: cos² x + sin² x = 1

Let the angle be x

8.

cos² x + sin² x = 1

cos² x + (4√13)/17 = 1

cos² x = 1 - (4√13)/17

cos² x = 81 / 289

cos x = √(81 / 289)

cos x = 9/17

10.

sec x = 5/3 and sec x = 1 / cos x, therefore

cos x = 3/5

x = arc cos 3/5

x = 53.1301

sin x = 0.8

12.

sec x = 5/4 and sec x = 1 / cos x, therefore

cos x = 4/5

Use the graph to solve -x^2+2x+3=0. Select all solutions that apply.

Answers

x = -1 and x = 3 are the solutions to the equation [tex]-x^2+2x+3=0[/tex].

To solve the quadratic equation[tex]-x^2+2x+3=0[/tex], we can use the quadratic formula:

[tex]x = \frac{(-b \pm \sqrt{b^2 - 4ac)} }{2a}[/tex]

In this case, a = -1, b = 2, and c = 3, so we can substitute these values into the formula:

[tex]x = \frac{(-2 \pm \sqrt{2^2 - 4*1*3)} }{2*-1}[/tex]

x = (-2 ± sqrt(16)) / (-2)

x = (-2 ± 4) / (-2)

Simplifying this expression, we get:

x₁ = (-2 + 4) / (-2) = -1

x₂ = (-2 - 4) / (-2) = 3

Therefore, the solutions to the equation [tex]-x^2+2x+3=0[/tex] are x = -1 and x = 3.
