Question:

What is 8,743 divided by 4?

Explanation:

Heya, I heard you need help! Well, let me explain for ya! c:

Step 1: Divide.

- First, you would write down the division problem using long division, let me show you how:

1. Write it down in long division form.

2. 4 can go into 8 2 times, so subtract that by 8 to get a difference of 0.

3. Subtract 8 by 8 and get a difference of 0.

4. 4 cannot go into 0, so bring down the 7.

5. 4 goes into 7 1 time, so you would subtract 7 by 4 to get a difference of 3.

6. 4 cannot go into 3, so bring down the 4.

7. 4 goes into 34 8 times, so you would subtract 34 by 32 to get a difference of 2.

8. 4 does not go into 2, so bring down the 3.

9. 4 goes into 23 5 times, so you subtract 23 by 20 to get a difference of 3.

10. 4 does not go into 3, so you bring down an imaginary 0 and add a decimal on the left of the 3 in 8743.

11. 4 goes into 30 7 times as 7 times 4 is 28, so subtract 30 by 28 to get a difference of 2.

12. Finally, you bring down another 0 as 4 cannot go into 2. Then, you subtract 20 by 20 to get 0.

- Your quotient is 2185.75.

Step 2: Converting to a mixed number.

- This is the easiest part. All you have to do is convert 75/100 into simplest form as 75/100 is the decimal in fraction form. This will get you 3/4.

- Then, you would write 2185 \(\frac{3}{4}\).

Therefore, your answer is 2185 \(\frac{3}{4}\)

Also, sorry about that book for a math problem.

Hope that helped! If you have anymore questions, just comment down and I will try my best to help you! Au revoir!

The domain of a function is the set of numbers that can go into a given function.

The set of input values (x) for which a function generates an output value is known as the domain of the function (y).

we can write \(y = f(x).\)

domain is the full set of x-values that can be plugged into a function to produce a y-value.

The most effective approach to finding a domain will depend on the type of function.

The domain is expressed using an open bracket or parenthesis, the domain's two endpoints separated by a comma, and then a closed bracket or parenthesis.

To find domain of function we should know the property of that function like what the function can take inside it.

Like if we consider square root function \(\sqrt{x}\) so inside root negative numbers are not allowed so value of x should be positive means x>=0

So domain of square root function [0, ∞).

Cube roots of -1 mean "finding solution of the equation z³ = -1 since the equation is of order 3, the equation has 3 roots in complex field."

According to the question,

Cube roots of -1 can written as \((-1)^\frac{1}{3}\)

First, write the given number in polar form

\(x = ( cos 0 - i sin 0)^\frac{1}{3}\)

Step-by-step explanation:

The minimum score needed to receive a grade of A is approximately 86.06.

To find the minimum score needed to receive a grade of A, we need to determine the cutoff point that corresponds to the top 12.3 percent of students in a normal distribution with a mean of 65 and a standard deviation of 18.

First, we need to find the z-score associated with the top 12.3 percent.

The z-score represents the number of standard deviations a data point is from the mean.

Using a standard normal distribution table or a calculator, we can find the z-score that corresponds to the top 12.3 percent.

The z-score is approximately 1.17.

Next, we can use the formula for z-score conversion to find the corresponding score value:

z = (x - μ) / σ

Rearranging the formula to solve for x (the score):

x = z * σ + μ

Plugging in the values:

x = 1.17 * 18 + 65

x ≈ 86.06

Therefore, the minimum score needed to receive a grade of A is approximately 86.06.

Candice's z-score is lower than Erin's z-score, this means that Candice performed better relative to the rest of her peers than Erin did relative to hers. Therefore, Candice scored better on the exam than Erin did.

To explain, we can use the concept of z-scores, which allow us to compare scores from different normal distributions. The z-score for Candice's score of 74 is calculated as: z = (74 - 66) / 4 = 2

This means that Candice's score is two standard deviations above the mean for her exam. The z-score for Erin's score of 58 is calculated as: z = (58 - 42) / 7 = 2.29

This means that Erin's score is 2.29 standard deviations above the mean for her exam. Hence, Candice scored better on the exam.

Answer:

Step-by-step explanation:

In a sample of 26 days from the desert, the average of the high daily temperature is 114 degrees F, and the sample standard deviation is 5 degrees F.

To determine the 90% confidence interval for the average temperature, we can use the t-distribution as follows:To find the critical value of t, we can use the t-table. Since our sample has n = 26, the degrees of freedom (df) are n - 1 = 25. At a confidence level of 90%, with 25 degrees of freedom, the critical t-value is 1.708.The standard error of the mean is calculated as s / sqrt(n), where s is the sample standard deviation and n is the sample size. Therefore, the 90% confidence interval for the average temperature is (114 - 1.67, 114 + 1.67), or (112.33, 115.67) degrees F.

Answer:

1) Pr(all three) = 0.064

2) Pr(none) = 0.216

3) Independent event

Step-by-step explanation:

Let Probability of homes constructed in the Quail Creek area with a security system = Pr (security)

Where Pr = probability

This is a binomial distribution problem. There ate only two outcomes in this distribution: a success and a failure

Where p = success, q = failure

For n trials,

Pr(X = x) = n!/[(n-x)!x!] × p^x × q^(n-x)

Pr (security) = 40% = 0.4

p = 0.4

q = 1-p = 1-0.4 = 0.6

Numbers selected at random = n = 3

See attachment for more details on the workings.

1) Probability all three of the selected homes have a security system = Pr(all three)

Pr(all three) = 1× (0.4)³ (0.6)^0 = 0.4³

= 0.4×0.4×0.4

Pr(all three) = 0.064

2) Probability none of the three selected homes have a security system

= Pr(none)

Pr(none) = 1 × (0.4)^0 × (0.6)³

= 0.6³ = 0.6×0.6×0.6

Pr(none) = 0.216

3) The events were assumed to be independent as the selection of one house doesn't affect the outcome of the selection of another.

The angle between two pointers say, no. 12 and no. 8 in a clock is 120° or 2.094 radians.

According to given question, we can say clock is showing 8:00 am. At 8'o clock the two pointers will just touch the no. 12 and no. 8. In a clock at the centre angle 360° must be divided into 12 equal or similar sections. The value of angle for each section in clock is 360° / 12 = 30° .

The counting of angle is always anti clock wise direction so , at 12 the two pointers postion is 360° .. As time passes the angle0 reduces each section ( 1 hour ) by 30° ..as every hours one pointers remains at no. 12 ..

At 8'o clock 8 such sections reduced .

Now, the angle between two pointers is 360° - 8× 30 = 360° - 240° = 120°..

Using the formula for reducing degree to radians , 1 degree = π / 180° radians

=> 120 ° × π / 180° radians = 2.094 radians .

Thus, the angle between two pointers no. 12 and no. 8 is 2.094 radians.

The absolute maximum value is 20/17, which occurs at x = 5, and the absolute minimum value is 4/5, which occurs at x = 1.

To find the absolute maximum and minimum values of the function f(x) = 8x/(6x + 4) on the interval (1, 5), we need to find the critical points of the function within the interval and evaluate the function at those points, as well as at the endpoints of the interval.

First, let's find the derivative of the function:

f(x) = 8x/(6x + 4)

f'(x) = [8(6x + 4) - 8x(6)] / (6x + 4)^2

f'(x) = [8(2)] / (6x + 4)^2

f'(x) = 16 / (6x + 4)^2

The critical points occur when f'(x) = 0 or is undefined. However, since f'(x) is always positive on the interval (1, 5), there are no critical points within the interval.

Next, let's evaluate the function at the endpoints of the interval:

f(1) = 8(1)/(6(1) + 4) = 8/10 = 4/5

f(5) = 8(5)/(6(5) + 4) = 40/34 = 20/17

Finally, we need to determine which of these values is the absolute maximum and which is the absolute minimum.

Since f(x) is always positive on the interval (1, 5), the function can never be less than 0. Therefore, the absolute minimum value is the smallest value of f(x) on the interval, which occurs at x = 5, where f(5) = 20/17.

To find the absolute maximum value, we compare the values of f(1), f(5), and the maximum value of f(x) as x approaches the endpoints of the interval. We can use the fact that the function is continuous on the closed interval [1, 5] to find the maximum value.

As x approaches 1, we have:

f(x) = 8x/(6x + 4) → 8/10 = 4/5

As x approaches 5, we have:

f(x) = 8x/(6x + 4) → 40/34 = 20/17

Therefore, the absolute maximum value is 20/17, which occurs at x = 5, and the absolute minimum value is 4/5, which occurs at x = 1.

m = \(\frac{1-(-1)}{9-3}\) = \(\frac{1+1}{6}\) = \(\frac{2}{6}\) = \(\frac{1}{3}\)

The mean of T is -10 and the standard deviation of T is √425 when X1 and X2 are independent.

To find the mean of T, we can use the properties of expected values. Since T = 11X1 - 2X2, the mean of T can be calculated as follows: E(T) = E(11X1) - E(2X2) = 11E(X1) - 2E(X2) = 11(10) - 2(20) = -10. To find the standard deviation of T, we need to consider the variances and covariance of X1 and X2. Since X1 and X2 are independent, the covariance between them is zero. Therefore, Var(T) = Var(11X1) + Var(-2X2) = 11^2Var(X1) + (-2)^2Var(X2) = 121(2^2) + 4(3^2) = 484 + 36 = 520. Thus, the standard deviation of T is √520, which simplifies to approximately √425. When X1 and X2 have a correlation of -0.76, the mean and standard deviation of T remain the same as in the case of independent variables. To calculate the probability P(T > 30) when X1 and X2 are independent, normally distributed variables, we need to convert T into a standard normal distribution. We can do this by subtracting the mean of T from 30 and dividing by the standard deviation of T. This gives us (30 - (-10))/√425, which simplifies to approximately 6.16.  We can then look up the corresponding probability from the standard normal distribution table or use statistical software to find P(T > 30). The probability will be the area under the standard normal curve to the right of 6.16.

Considering the equation of an ellipse, it is found that the height of the tunnel 10 feet from the edge is of 14 feet.

The following is the equation for a horizontal ellipse of center with coordinates (h,k):

(x - h)²/a² + (y - k)²/b² = 1.

In relation to this issue, we have that:

The origin is where the center is.

Since the major axis is 70, 2a = 70 and a = 35.

The maximum height is 20, therefore b is equal to 20.

As a result, the ellipse's equation is as follows:

x²/35² + y²/20² = 1.

It is determined that x = 25 when the tunnel is 10 feet from the edge since 35 – 10 = 25; therefore, the height y is calculated as follows:

25²/35² + y²/20² = 1

0.51 + y²/20² = 1

y²/20² = 0.49

y² = 20² x 0.49

y =√(20² x 0.49)

y = 14 feet.
