Answer:

∠CED = 58°

Step-by-step explanation:

Clearly, we can see that ∠AED and ∠CED are a linear pair. Therefore:

Definition of Linear pair: A linear pair is two angles that form a 180 angle.

We are given that:

Therefore, when we substitute the measure of ∠AED, we get;

This problem is now an algebraic problem. Simply isolate ∠CED on one side of the equation to determine the measure of ∠CED. This can be done by subtracting 122 both sides of the equation.

Therefore, the measure of ∠CED is 58°.

The measure of angle CED is 58° adjacent to the angle AED.

A pair of linear angles are adjacent to each other whose sum is 180°.

Given, a measure of the angle AED is 122°

We know the measure of linear pair of angles is 180°.

∴ m∠AED + m∠CED = 180°.

122° + m∠CED = 180°.

m∠CED = 180° - 122°.

m∠CED = 58°.

Answer:

∠ 1 = 58°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

117° is an exterior angle of the triangle, then

∠ 1 + 59° = 117° ( subtract 59° from both sides )

∠ 1 = 58°

Answer:

Part A

The addition equation that gives Amber's total running time is presented as follows;

Amber's total running time = 1/6 hr + (1/6 + 1/12) hr  + 5/12 hr

Part B

Amber's total running time = 5/6 hr = 50 minutes

Step-by-step explanation:

Part A

The given parameters are;

The time duration Amber first ran = 10 min = 1/6 hr

The time duration Amber walks in between = 5 min = 1/12 hr

The increase in the number of minutes Amber runs in subsequent times = 5 min = 1/12 hr

Therefore, the Amber's total time is given as follows;

1/6 hr + 1/12 hr + (1/6 + 1/12) hr + 1/12 hr + x hr = 1 hr

7/12 hr + x hr = 1 hr

x hr = 1 hr - 7/12 hr  = 5/12 hr

x = 5/12

Therefore, her total running time is given by the following addition equation;

Amber's total running time = 1/6 hr + (1/6 + 1/12) hr  + 5/12 hr

Part B

Therefore her total running time is given as follows;

Amber's total running time = 1/6 hr + (1/6 + 1/12) hr  + 5/12 hr = 5/6 hr = 50 minutes

The number of times that a flip comes up heads followed immediately by a flip that is tailsis  10/4.

To solve this problem, we can use the linearity of expectation. Let's consider the first two flips. The probability that they are HT is 1/4, and if they are, then X = 1. If they are not, then we ignore them and consider the next two flips, and so on. So, the expected value of X can be calculated as:

E[X] = (probability of getting HT on the first two flips) * 1 +

(probability of not getting HT on the first two flips) * (expected value of X for the remaining flips)

The probability of getting HT on the first two flips is 1/4, as mentioned earlier. The probability of not getting HT on the first two flips is 3/4. For the remaining eight flips, the situation is exactly the same as the original problem, except that we now have eight flips instead of ten. So, the expected value of X for the remaining flips is E[X] * 8/10.

Putting it all together, we get:

E[X] = (1/4) * 1 + (3/4) * (E[X] * 8/10)

= 1/4 + 6/10 * E[X]

Solving for E[X], we get:

E[X] = 10/4

Therefore, the answer is A) 10/4.

False. Using the specified side measures of 4.6, 2.7, and 1.9, a triangle cannot be created.

Any two side lengths must add up to more than the third side length in order for a triangle to have three sides. The two smaller sides in this scenario do not add up to be greater than the longest side because we can see that 1.9 + 2.7 = 4.6.

The Triangle Inequality Theorem stipulates that the total of any two triangle sides must be bigger than the third side. This isn't true in this case. Hence, a triangle cannot be formed with the side measurements provided.

In conclusion, it cannot be said that a triangle can have sides that measure 4.6, 2.7, and 1.9.

a) The given function is f(x) = x⁴ − 2x² + 3. We can find the local maxima and minima of the function using its first derivative

:f(x) = x⁴ − 2x² + 3f'(x) = 4x³ − 4xIf f'(x) = 0, then x = 0 or x = ±1.

The critical values of f(x) are −1, 0, and 1.Therefore, the function has local maxima at x = ±1 and a local minimum at x = 0.b) We need to find the intervals of concavity and the inflection point of the given function.

To find the concavity, we will use the second derivative

:f(x) = x⁴ − 2x² + 3f'(x) = 4x³ − 4xf''(x) = 12x² − 4If f''(x) = 0, then x = ±sqrt(3/2).The critical values of f''(x) are −sqrt(3/2) and sqrt(3/2).

Therefore, the function is concave upward on the intervals (−∞, −sqrt(3/2)) and (sqrt(3/2), ∞) and concave downward on the interval (−sqrt(3/2), sqrt(3/2)).

The inflection point of the function is at x = ±sqrt(3/2).c) To find the intervals on which the function is increasing or decreasing, we need to analyze the sign of the first derivative:

f(x) = x⁴ − 2x² + 3f'(x) = 4x³ − 4xThe function is decreasing on the interval (−∞, 0) and increasing on the intervals (0, 1) and (−1, ∞).

Thus, the function is increasing on (0, ∞) and decreasing on (−∞, 0).So, the intervals of increase are (0, ∞) and intervals of decrease are (−∞, 0).

Therefore, the simple answer is:

a) The function has a local maximum at x = ±1 and a local minimum at x = 0.

b) The function is concave upward on the intervals (−∞, −sqrt(3/2)) and (sqrt(3/2), ∞) and concave downward on the interval (−sqrt(3/2), sqrt(3/2)).

The inflection point of the function is at x = ±sqrt(3/2).c) The function is increasing on (0, ∞) and decreasing on (−∞, 0).

Answer :(5,5) is not a solution to both equations simultaneously, it is not a solution to the system of equations. ¹

Step-by-step explanation: To check if (5,5) is a solution to the system of equations 5x-2y=-10 and 15x-16y=-5, we can substitute x=5 and y=5 into both equations and see if the left-hand side equals the right-hand side.

For the first equation, we have 5(5)-2(5)=-5-10=-15 which is not equal to the right-hand side of the equation. Therefore, (5,5) is not a solution to the first equation.

For the second equation, we have 15(5)-16(5)=75-80=-5 which is equal to the right-hand side of the equation. Therefore, (5,5) is a solution to the second equation.

The linear trend models estimated from 10 years of quarterly data can be enhanced by incorporating seasonal dummy variables \(d_{2}\) and \(d_{3}\), where d₁ =1 for quarter 1 and 0 for all other quarters. These dummy variables help capture the seasonal patterns and improve the accuracy of the trend model.

In time series analysis, it is common to observe seasonal patterns in data, where certain quarters or months exhibit consistent variations over time. By including seasonal dummy variables in the linear trend model, we can account for these patterns and obtain a more accurate representation of the data.

In this case, the seasonal dummy variables \(d_{2}\) and \(d_{3}\) are introduced to capture the seasonal effects in quarters 2 and 3, respectively. The dummy variable \(d_{1}\) is set to 1 for quarter 1, indicating the reference period for comparison.

Including these dummy variables in the trend model allows for a more detailed analysis of the seasonal variations and their impact on the overall trend. By estimating the model with and without these dummy variables, we can assess the significance and contribution of the seasonal effects to the overall trend.

In conclusion, incorporating seasonal dummy variables in the linear trend model enhances its ability to capture the seasonal patterns present in the data. This allows for a more comprehensive analysis of the data, taking into account both the overall trend and the seasonal variations.
