The correct explanation for how ΔAEB could be proven similar to ΔDEC using the AA similarity postulate is:∠AEB ≅ ∠DEC because vertical angles are congruent; reflect ΔCED across segment FG, then dilate ΔCED to confirm segment EB ≅ segment ED.

This is because the AA similarity postulate states that if two pairs of corresponding angles in two triangles are congruent, then the triangles are similar. In this case, ∠AEB and ∠DEC are congruent vertical angles, and by reflecting ΔCED across segment FG and dilating it, segment EB can be made congruent to segment ED, which completes the proof of similarity by AA.

Answer:

220

Step-by-step explanation:

If we take 20 common (as in we can take it out and group the rest) , we can say 20 (15 7/9-4 7/9) which is equal to 20 (11). 20x11 = 220.  

The hypotheses for the test are H₀: σ₁² = σ₂² and H₁: σ₁² ≠ σ₂². This is a two-tailed test to assess if there is a difference in the standard deviations of sound levels between the areas designated as "casualty doors" and operating theaters. The claim being investigated is whether or not there is a difference in the standard deviations.

The hypotheses for the test are:

H₀: σ₁² = σ₂² (There is no difference in the standard deviations of the sound levels between the areas designated as "casualty doors" and operating theaters.)

H₁: σ₁² ≠ σ₂² (There is a difference in the standard deviations of the sound levels between the areas designated as "casualty doors" and operating theaters.)

This hypothesis test is a two-tailed test because the alternative hypothesis is not specifying a direction of difference.

To substantiate the claim that there is a difference in the standard deviations, we will conduct a two-sample F-test at a significance level of 0.10, comparing the variances of the two groups.

Answer:

Step-by-step explanation:

If a 6-ounce bottle of medicine contains 36 doses, we can use a proportion to find how many doses are in a 15-ounce bottle:

6 ounces / 36 doses = 15 ounces / x doses

Cross-multiplying, we get:

6 x = 36 * 15

6 x = 540

Dividing both sides by 6, we get:

x = 90

Therefore, a 15-ounce bottle of the same medicine contains 90 doses.

The distributive property allows the formula (-128 x 46) + (128 x -36) to be simplified to -10496.

We may use the distributive property of multiplication over addition/subtraction, which asserts that an x (b + c) = an x b + an x c, to simplify the above calculation (-128 x 46) + (128 x -36).

Let's dissect the expression in detail:

(-128 x 46) + (128 x -36)Let's first assess the goods:

-128 x 46 = -5888

128 x -36 = -4608

Reintroduce these values into the phrase now:

(-5888) + (-4608)

We simply add the absolute values of the two negative numbers while maintaining the sign of the negative:

-5888 + (-4608) = -10496

Consequently, -10496 is the reduced expression.

Last but not least, the phrase (-128 x 46) + (128 x -36) becomes -10496. .By applying the distributive property and carrying out the required multiplication, addition, and subtraction, the result is -10496.

A is an n x n diagonal matrix with rank r , where rsn  and the statement (a)"O is an eigenvalue with algebraic muitiplicity n-r "  about A is true

Since A is an n x n diagonal matrix with rank r, the number of non-zero entries on the diagonal is r. This means that there are n - r zero entries on the diagonal.

For any diagonal matrix, the eigenvalues are simply the entries on the diagonal. Since there are n - r zero entries, the eigenvalue O has a geometric multiplicity of n - r.

Therefore, the correct statement is that O is an eigenvalue with geometric multiplicity n - r.

Barton should use a luggage scale to get the most accurate and appropriate measurement of his packed suitcase before he leaves to catch a flight. A luggage scale is a compact and portable device that is designed specifically to weigh luggage. Using a luggage scale is easy and convenient as it allows travelers to weigh their bags accurately, ensuring that they are within the airline's weight limit. To use a luggage scale, Barton should follow these simple steps:

Step 1: Attach the luggage strap Barton should attach the luggage strap to the handle of his suitcase.The strap should be attached in such a way that it can support the weight of the suitcase without slipping or coming off.

Step 2: Turn on the luggage scale Barton should turn on the luggage scale and wait for it to calibrate. This usually takes a few seconds. Once the scale is calibrated, it will display a zero reading.

Step 3: Lift the suitcase Barton should lift the suitcase by the luggage strap until it is off the ground. The luggage scale will display the weight of the suitcase on its digital display. This reading is the weight of the suitcase including all the contents inside.

Step 4: Check the weight If the weight of the suitcase is less than 50 pounds, Barton can go ahead and catch his flight without worrying about any extra charges. If the weight of the suitcase is more than 50 pounds, Barton will have to remove some items from the suitcase or pay the extra fee charged by the airline.

Therefore, using a luggage scale is the most accurate and appropriate method for travelers like Barton to measure their suitcase weight before boarding their flight.

The entries of the table, denoted as T(i, j), represent the length of the longest nicely spaced subsequence ending at index i, with the difference between the last element and the element at index j.

The recurrence relation for the entries of the table can be defined as follows:

  T(i, j) = max(T(j, k) + 1), where 0 <= k < j and |S(i) - S(j)| <= 5.

  This means that we consider all previous elements (j) that have a difference of at most 5 with the current element (i), and we update the maximum length of the nicely spaced subsequence by adding 1 to the length of the subsequence ending at index j (T(j, k)).

  The base case is T(i, j) = 1, where there are no previous elements that satisfy the nicely spaced condition.

Pseudocode for the algorithm:

  Initialize an array T with length n, where n is the length of the input sequence S.

  Set all values in T to 1.

  Initialize a variable max_length to 1.

  for i = 1 to n:

      for j = 1 to i-1:

          if |S[i] - S[j]| <= 5:

              T[i] = max(T[i], T[j] + 1)

              max_length = max(max_length, T[i])

  Return max_length as the length of the longest nicely spaced subsequence of S.

The running time of this algorithm can be analyzed as follows:

  - The outer loop iterates through each element of the sequence, so it takes O(n) time.

  - The inner loop iterates through all previous elements for each element, so it takes a total of O(n^2) time in the worst case.

  - Therefore, the overall time complexity of the algorithm is O(n^2).

  Since we only use an array of size n (T) to store the lengths of subproblems, the space complexity is O(n).

Answer:   True

Step-by-step explanation:

The term inside the parentheses after the summation sign is

       x-sub-i    minus    x-bar

x-bar is the mean average of all the individual n observations. In statistics, it is usually just called the 'mean' for short.

x-sub-i stands for each individual observation: x-sub-1, x-sub-2, and so on

So that means (x-sub-i   -   x-bar) means the difference we get if we do the subtraction, using x-sub-i as the first term in the subtraction.

For an illustration of this, suppose we have a sequence of 5 observations. Since there are 5 observations, n = 5.

x-sub-1  = 4

x-sub-2 = 7

x-sub-3 = 3

x-sub-4 = 11

x-sub-5 = 5

We obtain the mean by adding all the observations and then dividing by the number of observations, n.

The sum 4+7+3+11+5 = 30 and 30/5 = 6.

So the mean, x-bar, = 6.

Now let's look at all the differences between each observation and x-bar.

In the same order as the observations, we get

4 - 6  = -2

7 - 6  =  1

3 - 6 = -3

11 - 6 = 5

5 - 6  = -1

If we add up all the differences, just like we are doing in the summation homework problem, we have (-2)+1+(-3)+5+(-1) = 0.

It also works if you make x-bar the first term in the subtraction. Either way will work, as long as you are consistent about it from one subtraction to the next.

This is always the case with a mean average, so the summation is assured to be zero.
