Answer:

to find y you have to do trigonometry

Answer:

18/28

Step-by-step explanation:

The value of  x′y = -∂F/∂y / ∂F/∂x , y = y(x, z): y′z = -∂F/∂z / ∂F/∂y and z′x = -∂F/∂x / ∂F/∂z. The expression x′y represents the partial derivative of x with respect to y.

Using the implicit differentiation formula, we can calculate x′y as follows: x′y = -∂F/∂y / ∂F/∂x.

Similarly, y′z represents the partial derivative of y with respect to z. To find y′z, we use the implicit differentiation formula for y = y(x, z): y′z = -∂F/∂z / ∂F/∂y.

Lastly, z′x represents the partial derivative of z with respect to x. Using the implicit differentiation formula, we have z′x = -∂F/∂x / ∂F/∂z.

These expressions allow us to calculate the derivatives of the variables x, y, and z with respect to each other, given the implicit function F(x, y, z) = 0. By taking the appropriate partial derivatives and applying the division formula, we can determine the values of x′y, y′z, and z′x.

a) Using the sum or difference formula for sine, we can find sin 75° by considering it as sin (60° + 15°). By substituting known values, sin 60° = √3/2 and sin 15° = (√6 - √2)/4, along with cos 60° = 1/2 and cos 15° = (√6 + √2)/4, we can simplify the equation to (√18 + √2)/8.

b) Utilizing the half-angle formula for sine, sin 75° can be expressed as ±√((√3 + 1)/2), where we consider 75° as half of 150° and utilize cos 150° = -√3/2. By substituting these values into the formula, we obtain the exact value of sin 75°.

Answer: 12.5 meters!

Step-by-step explanation:

So 5km = 5000 meters

So take 5000 divided by 400 = 12.5 meters

Answer:

12.5 is the answer for this question

Answer:

7

Step-by-step explanation:

The start this question by looking at two important things, how much money we have and how much money it costs per person. The friends have a total of $284.25 and we don't know how much it costs per person. To find this we must set up an equation and solve it!

Because each person must pay for parking and a ticket, we can find the cost for one person by adding the parking and ticket cost together.

$9.25 + $27.50 = $36.75

Now that we have solved this equation, we know that it costs $36.75 for one person. To find how many total people can go we dived the total amount of money we have by how much it costs per person. Let's call the number of people that can go 'p'.

p = \(\frac{284.25}{36.75}\)

Once we simplify/solve this equation we get 7 \(\frac{36}{49}\) so essentially, we get the whole number 7 and a long decimal, but the only important part is the 7. We take the whole number from our answer which is 7.

We now know the answer: 7.

Let's check our work!

7 * 36.75 = 257.75

284.25 - 257.75 = 26.5

26.5 < 36.75 so we are correct!

The final answer is 7!

Answer:

5%, 1/5, 0.5

Step-by-step explanation:

To arrange the values in order, starting with the smallest, we can convert them to a consistent format.

First, let's convert 1/5 to decimal form. 1/5 is equal to 0.2.

Now we have the following values:

0.5, 0.2, 5%

To compare these values, we need to convert 5% to decimal form. 5% is equal to 0.05.

Now we have the final values:

0.2, 0.5, 0.05

Arranging them in order from smallest to largest:

0.05, 0.2, 0.5

= 5%, 1/5, 0.5

The values of a and b that make the piecewise defined function f(x) = 3x + 4, for x < -3, and f(x) = 2x^2 + ax + b, for x > -3, both continuous and differentiable everywhere are a = 6 and b = 9.

To ensure that the piecewise defined function is continuous at the point where x = -3, we need the left-hand limit and right-hand limit to be equal. The left-hand limit is given by the expression 3x + 4 as x approaches -3, which evaluates to 3(-3) + 4 = -5.

On the right-hand side of the function, when x > -3, we have the expression 2x^2 + ax + b. To find the value of a, we need the derivative of this expression to be continuous at x = -3. Taking the derivative, we get 4x + a. Evaluating it at x = -3, we have 4(-3) + a = -12 + a. To make this expression continuous, a must be equal to 6.

Next, we find the value of b by considering the right-hand limit of the piecewise function as x approaches -3. Substituting x = -3 into the expression 2x^2 + ax + b, we get 2(-3)^2 + 6(-3) + b = 18 - 18 + b = b. To make the function continuous, b must equal 9.

Therefore, the values of a and b that make the piecewise defined function both continuous and differentiable everywhere are a = 6 and b = 9.

This probability is greater than 1, which is not possible.

This suggests that there may be an error in the problem statement, or that some additional information is required to correctly solve the problem.

The probability of a store being a Kwik Save is:

P(Kwik Save) = 1000 / (1000 + 424) = 1000 / 1424 = 0.7037

The probability of a store closing, given that it is a closing store, is:

P(closing| Kwik Save) = 107 / (107 + 324) = 107 / 431 = 0.2488

The probability of a store being a closing store is:

P(closing) = (107 + 324) / (1000 + 424) = 431 / 1424 = 0.3029

The probability of a randomly chosen store being either closing or Kwik Save is:

P(closing or Kwik Save) = P(closing) + P(Kwik Save) - P(closing and Kwik Save)

= 0.7037 + 0.3029 - (107 / 1424)

= 0.8997

The probability that a randomly selected store is not closing given that it is a Somerfield is:

P(not closing| Somerfield) = 1 - P(closingl Somerfield)

To find P(closing| Somerfield), we can use Bayes' theorem:

P(closing| Somerfield) = P(Somer field| closing) * P(closing) / P(Somerfield)

P(Somerfield| closing) is the probability that a store is a Somerfield given that it is closing.

Since all the Somerfield stores are closing, this probability is 1.

P(Somerfield) is the probability that a store is a Somerfield.

It is:

P(Somerfield) = 424 / (1000 + 424) = 424 / 1424 = 0.2980

Therefore,

P(closing| Somerfield) = 1 * 0.3029 / 0.2980 = 1.0151.

The number of terms required to achieve a desired accuracy in finding the sum of a series depends on the specific series and the level of accuracy desired. In general, as we add more terms to the series, the approximation of the sum improves, leading to a higher level of accuracy.

To understand how many terms are needed to find the sum with a given accuracy, let's consider an example. Suppose we have an infinite series represented as:

S = a + b + c + d + ...

where 'a', 'b', 'c', 'd', and so on are the terms of the series.

To find the sum of this series, we can take partial sums by adding a certain number of terms. For example, if we add only the first two terms, we get S2 = a + b. If we add the first three terms, we get S3 = a + b + c. The more terms we add, the closer the partial sum gets to the actual sum of the series.

The accuracy of our approximation is determined by the difference between the partial sum and the actual um. To specify the desired accuracy, we can define an error tolerance or a maximum allowable difference between the partial sum and the actual sum.

For instance, if we want our approximation to be accurate within a certain threshold, say ε, we need to find the smallest number of terms that make the difference between the partial sum and the actual sum less than ε.

The number of terms required to achieve the desired accuracy will depend on the convergence properties of the series. Some series converge rapidly, meaning that adding a few terms yields a very accurate approximation, while others converge slowly, requiring a larger number of terms for the same level of accuracy.

To determine the number of terms needed, we can use convergence tests specific to the series at hand. These tests include the Ratio Test, the Root Test, and the Comparison Test, among others. These tests help us determine whether a series converges or diverges and provide insights into its convergence rate.

In summary, the number of terms required to find the sum of a series with a given accuracy depends on the specific series and the desired level of accuracy. By using convergence tests and considering the error tolerance, we can estimate the number of terms needed to achieve the desired accuracy in approximating the sum of the series.

We can be 95% confident that the true mean concentration of THMs in your drinking water lies within the range [2.9584 ppb, 3.0416 ppb]. This was calculated using a confidence interval formula for the mean.

The confidence interval for the mean concentration of THMs can be calculated using the formula x ± z * (s/√n), where x is the sample mean, z is the z-score for a given confidence level, s is the sample standard deviation and n is the sample size.

In this case, we have x = 3 ppb, s = 0.3 ppb, and n = 200. To calculate the confidence interval at a certain confidence level (e.g. 95%), we need to find the corresponding z-score. For a 95% confidence level, the z-score is approximately 1.96.

Substituting these values into the formula above gives us:

3 ± 1.96 * (0.3/√200) = [2.9584, 3.0416]

So we can be 95% confident that the true mean concentration of THMs in your drinking water lies within the range [2.9584 ppb, 3.0416 ppb].

With 70% off the regular price, a dishwasher, regularly priced at $519.89, will be $155.97 only. The answer is C.

Discount is the deduction in the price of a good or service. When this reduced price is expressed in percentage then we call it a discount rate.

If the discount is given in percent, then the amount of discount can be found by using the formula:

Amount of Discount = Regular Price × Rate of Discount

If the regular price of a dishwasher is $519.89, and the discount rate is 70%, using the formula, solve for the discount value.

Amount of Discount = $519.89 x 70%

Amount of Discount = $519.89 × 0.70

Amount of Discount = $363.92

To get the final price of the dishwasher, subtract the discount value from the original or regular price.

We have 7 blue marbles, and 20 total marbles. As a result, if we randomly chose one marble from the bag, the probability would be (number of favorable outcomes)/(number of total outcomes) = 7/20.

This means that for each 20 trials, we would expect to pull out a blue marble 7 times, as the probability does not change over time (because we put the marbles back, there are the same amount of each marble). Over 200 trials, we can simply make it out of 200 instead of 20. We can thus multiply 7/20 by 10/10 (10/10 is equal to 1, keeping the proportions equal) to get 70/200, so we can expect 70 blue marbles out of 200.

The probability of getting fewer than 2 successes is approximately 0.5751.

To find the probability of getting fewer than 2 successes in a binomial experiment with probability of success p = 0.36 and m = 7 trials, we need to calculate the probability of getting 0 or 1 success.

The probability of getting k successes in a binomial experiment with m trials is given by the binomial probability formula:

\(P(X = k) = C(m, k) * p^k * (1 - p)^{(m - k)\)

where C(m, k) is the number of combinations of m items taken k at a time, given by the formula:

C(m, k) = m! / (k! * (m - k)!)

For the given scenario, we want to calculate P(X < 2), which means finding P(X = 0) + P(X = 1).

\(P(X = 0) = C(7, 0) * 0.36^0 * (1 - 0.36)^{(7 - 0)} = 1 * 1 * 0.64^7 = 0.2079P(X = 1) = C(7, 1) * 0.36^1 * (1 - 0.36)^{(7 - 1)} = 7 * 0.36 * 0.64^6 = 0.3672\)

Therefore, the probability of getting fewer than 2 successes in this binomial experiment is:

P(X < 2) = P(X = 0) + P(X = 1) ≈ 0.2079 + 0.3672 = 0.5751

So, the probability of getting fewer than 2 successes is approximately 0.5751.
