fouth Quadrent, 360-332  

                                                     Answer is equal to 28

Answer:

Quadrant 1: 152°

Quadrant 2: 28°

Quadrant 3 (Given): 332°

Quadrant 4: 208°

Step-by-step explanation:

A 332° angle in standard position has its terminal side in quadrant 3 since 332° is between 180° and 360°.

332° - 180° = 152°

The reference angle for 332° is 152°

Quadrant 1: 152°

Quadrant 2: 180° - 152° = 28°

Quadrant 3 (Given): 332°

Quadrant 4: 360° - 152° = 208°

The solution of the system of equation, 4x + 3y = 7 x - 2y = -1 are x = 1 and y = 1.

System of equation can be solved using different method such as elimination method and substitution method.

Therefore, using elimination method

4x + 3y = 7

x - 2y = -1

multiply equation(ii) by 4

4x + 3y = 7

4x  - 8y  = -4

subtract the equations

11y = 11

y = 1

x = - 1 + 2(1)

x = 1

Using substitution method,

Therefore,

4x + 3y = 7

x - 2y = -1

x = - 1 + 2y

susbtitute the value of x in equation(i)

4(-1 + 2y) + 3y = 7

-4 + 8y + 3y = 7

-4 + 11y = 7

11y = 7 + 4

11y = 11

y = 1

Therefore,

4x = 7 - 3

4x = 4

x = 1

Answer:

The angle x° = 34°

Step-by-step explanation:

Given the right-angled triangle

We know that the sum of angles of a triangle = 180°

so

90° + 56° + x° = 180°

x° = 180°- 90° - 56°

x° = 34°

Therefore, the angle x° = 34°

Answer:

$22.50

Step-by-step explanation:

Since the p-value (0.034) is less than the significance level of 0.05, we reject the null hypothesis. This suggests evidence against the claim that the median percent of impurities in the brand of jam is 2.5%.

To perform the sign test, we compare the observed values to the hypothesized median value and count the number of times the observed values are greater or less than the hypothesized median. Here's how we can proceed:

State the null and alternative hypotheses:

Null hypothesis (H0): The median percent of impurities in the brand of jam is 2.5%.

Alternative hypothesis (Ha): The median percent of impurities in the brand of jam is not 2.5%.

Determine the number of observations that are greater or less than the hypothesized median:

From the given data, we can observe that 5 jars have impurity percentages less than 2.5% and 11 jars have impurity percentages greater than 2.5%.

Calculate the p-value:

Since we are performing a two-tailed test, we need to consider both the number of observations greater and less than the hypothesized median. We use the binomial distribution to calculate the probability of observing the given number of successes (jars with impurity percentages greater or less than 2.5%) under the null hypothesis.

Using the binomial distribution with n = 16 and p = 0.5 (under the null hypothesis), we can calculate the probability of observing 11 or more successes (jars with impurity percentages greater than 2.5%) as well as 5 or fewer successes (jars with impurity percentages less than 2.5%). Summing up these probabilities will give us the p-value.

Compare the p-value to the significance level:

Since the significance level is 0.05, if the p-value is less than 0.05, we reject the null hypothesis. Otherwise, we fail to reject the null hypothesis.

We want to see which statement describes the image of a triangle after a dilation of scale factor of 2/3.

We will see that the correct option is C:

"Each angle has the same measure as its corresponding angle in the pre-image."

First, if we have a given figure and we apply a dilation of scale factor K, then all the measures of the given figures are affected by that dilation.

So if the 3 sides of the original triangle measured A, B, and C.

The new measures will be:

Notice that because all the sides changed proportionally, then the internal angles produced did not change after the dilation.

From this, we can conclude that the only correct option is C:

"Each angle has the same measure as its corresponding angle in the pre-image."

This says that the angles of the dilated triangle are the same ones as the angles of the initial triangle, which is true.

To show that no function m(x, y) on the domain [0,1]² satisfies the Laplace equation Δm = 0 and the Neumann boundary conditions ∂m/∂y (x,0) = ∂m/∂y (x,1) = ∂m/∂y (0,1) = 0 and ∂m/∂x (1,0) = 1, we can assume the existence of such a function and derive a contradiction.

Assuming that a function m(x, y) exists that satisfies Δm = 0 and the given Neumann boundary conditions, we can proceed by solving the Laplace equation using separation of variables. By separating m(x, y) into X(x)Y(y), we find that X''(x)/X(x) + Y''(y)/Y(y) = 0.

Solving the separated ODEs, we obtain X(x) = A + Bx and Y(y) = Ce^y + De^-y, where A, B, C, and D are constants. However, these solutions do not satisfy the given Neumann boundary conditions.

Specifically, the condition ∂m/∂x (1,0) = 1 implies that B = 1. But the boundary condition ∂m/∂y (0,1) = 0 requires D = 0, which conflicts with the solution Y(y) = De^-y. Therefore, no function m(x, y) can simultaneously satisfy the Laplace equation and the Neumann boundary conditions, leading to a contradiction.

Hence, we can conclude that no function m(x, y) exists that satisfies Δm = 0 and the given Neumann boundary conditions on the domain [0,1]².

The probability that the secretary will receive 6 calls next hour is approximately 0.090 or 9.0%.

The Poisson distribution is a probability distribution that describes the number of events occurring in a fixed time interval, given the average rate at which events occur and the independence of events. In this case, the average rate of calls is 3 calls per hour.

The probability of receiving exactly 6 calls next hour can be calculated using the Poisson probability formula:

\(P(X = 6) = (e^(-λ) * λ^6) / 6!\)

where λ is the average rate of calls, e is the base of the natural logarithm, and 6! is the factorial of 6.

Substituting the values, we get:

\(P(X = 6) = (e^(-3) * 3^6) / 6! ≈ 0.090\)

(b) To obtain the ck values and illustrate the relative size of each term in the Fourier series, we calculate the magnitude of each coefficient and plot their amplitudes on a bar graph against the corresponding frequency component, k.

To analyze the helicopter's acoustic signature, the real DFT is computed for the provided data set. The DFT transforms the time-domain measurements of acoustic pressure into the frequency domain, revealing the different frequencies present and their corresponding amplitudes. This analysis helps in understanding the spectral characteristics of the helicopter's acoustic signature and identifying prominent frequency components.

Using the Fourier series representation, the amplitudes (ck's) of the different frequency components in the Fourier series are determined. These amplitudes represent the relative sizes of each term in the series, indicating the contribution of each frequency component to the overall acoustic signature. By plotting the amplitudes on a bar graph, the relative strengths of different frequency components become visually apparent, enabling a clear comparison of their importance in characterizing the helicopter's acoustic signature.

A simple linear regression model predicts the response variable using a single predictor variable. In this case, the average relative skill is used to predict the total number of wins in a regular season.

In simple linear regression, the relationship between the predictor variable (average relative skill) and the response variable (total number of wins) is represented by the equation:

Wins = Intercept + Slope * Average Relative Skill

The overall F-test assesses the significance of the linear relationship between the predictor and response variables. The steps of this hypothesis test are as follows:

a. Null Hypothesis (H0): There is no significant linear relationship between average relative skill and the total number of wins in a regular season.

b. Alternative Hypothesis (Ha): There is a significant linear relationship between average relative skill and the total number of wins in a regular season.

c. Level of Significance: The chosen significance level (typically 0.05) determines the threshold for accepting or rejecting the null hypothesis.

d. The F-test statistic evaluates the overall significance of the regression model. It compares the explained variation (due to the model) to the unexplained variation (residuals). The associated p-value determines the statistical significance of the F-test.

By comparing the test statistic to the critical value and considering the p-value, we can make conclusions about the significance of the linear relationship between average relative skill and the total number of wins.

We need to use some basic algebraic equations. Let's assume that the initial payment made by Frankie was x, and the total amount he has to pay for the computer is y. Also, let's assume that Frankie will make n monthly payments.

Now, we know that Frankie has already paid x, and he has to pay y-x more. Since he will pay this amount in n monthly installments, we can represent the monthly installment as (y-x)/n.

So, the equation that represents the relationship between n and y can be written as:

y = x + n*(y-x)/n

Simplifying this equation, we get:

y = x + y-x

y = y

This means that the equation is true for any value of n and y, as long as x is a valid initial payment amount. Therefore, the equation that represents the relationship between n and y is:

y = x + n*(y-x)/n

The equation we derived above is a simple but important concept in mathematics and finance. It shows us that we can calculate the total amount we need to pay for something by multiplying the monthly installment by the number of payments and adding the initial payment to it. This concept is used in many financial transactions, such as car loans, mortgages, and credit card payments.

Moreover, this equation also helps us to plan our finances and manage our budget effectively. We can use it to calculate how much we need to save every month to reach our financial goals, or to compare different payment options and choose the one that suits us best.

In conclusion, the equation that represents the relationship between the number of monthly payments and the total amount paid is an essential tool for anyone who wants to make wise financial decisions. By understanding this equation, we can save money, avoid debt, and achieve our financial goals more easily.

The straight line that runs through the center of a round shape or object from one point on one edge to another: The diameter is twice as large as the radius. The pond is six feet across. Both definitions hold true for the diameter of a sphere.

We note that 25²+60²=65² and 39²+52²=65²

Let \(\bar{AB}\)=25, \(\bar{BC}\)=39, \(\bar{CD}\)=52, \(\bar{DA}\)=60

Let \(\bar{BD}\)=x and ∠DAB=y

x²=25²+60²-3000cos(y)

x²=39²+52²-4056cos(180-y)

We obtain by performing some computation x²=4225-3000cos(y) and x²=4225-4056cos(y).

4056cos(y)=3000cos(180-y)

cos(180-y)=-cos(y)

So, by substituting we get 4056cos(y)= -3000cos(y)

cos(y)=0 or y=90.

∠BAD=90 and ∠BCD=90.
