a. Jump with a bobbing motion: Shortest jump  b. Jump from deep knee flexion: Intermediate jump

c. Jump with fully extended knees: Longest jump ,In the long jump activity, three different jumping techniques were observed:

a) The bobbing motion involved bending and extending the knees and arms during the jump.

b) Starting from deep knee flexion meant initiating the jump from a position with knees bent and no motion prior to the jump.

c) Starting with fully extended knees involved jumping with the knees straight and no motion before the jump. During the performance, the lengths of each jump were measured. Trial results consistently indicated that the jump with the bobbing motion had the shortest length, while the jump starting from deep knee flexion had an intermediate length. The jump with fully extended knees consistently achieved the longest distance.

The observations reveal that starting the jump with fully extended knees and no knee motion results in the longest jump. The bobbing motion with knee and arm movements leads to the shortest jump. Deep knee flexion position falls between the two in terms of jump length.

Answer: x = 2

Step-by-step explanation:

The rule for reflecting over  x = 2 is that y remains the same and you add how many units x = 2 is from the point.

x = 2 is has the coordinate of x = 2 and y = the y coordinate of the point.

A (-1, 1) Since the y coordinate of (-1, 1) is 1, x = 2 - (2, 1)

Add 3 units to 2, the x coordinate since -1, 1 is 3 units from 2, 1

The fact that black youths are tried as adults more frequently than other races is a statistic. However, without further information such as sample size and significance level, it is difficult to determine the contribution to the test statistic and the p-value.

A larger sample size could potentially increase the test statistic and decrease the p-value, indicating a stronger relationship between race and being tried as an adult. On the other hand, a smaller sample size could result in a weaker relationship and a higher p-value. It is important to consider all relevant factors when interpreting statistics and making conclusions.
This result contributes to the test statistic, which is a numerical value that helps determine if there is a significant difference between the compared groups.

In this case, the test statistic would be larger, indicating a greater difference between the rates of black youths tried as adults and those of other races. A larger test statistic typically leads to a smaller p-value, which is a measure of the probability of observing such a difference by chance alone. A smaller p-value (usually less than 0.05) suggests that the observed difference is not due to chance and is statistically significant, indicating a possible disparity in the treatment of black youths within the justice system.

449 students were surveyed about their preferences for sports. 146 students like football, 107 students like baseball, and 49 students like both sports. there are 293  students like exactly one of the two sports.

This can be determined by subtracting the number of students who like both sports (49) from the total number of students surveyed (439). This leaves us with 390 students who like either football, baseball, or both. To find the number of students who like exactly one of the two sports, we will need to subtract the number of students who like both sports from the number of students who like either football or baseball.

To do this, we add together the number of students who like football (146) and the number of students who like baseball (107). This gives us 253 students who like either football or baseball. Subtracting this number (253) from the number of students who like either sport (390) gives us the number of students who like exactly one of the two sports (293).

Question: if n  balls are randomly placed into n cells, determine the probability that exactly one cell remains empty.

The probability that exactly one cell remains empty when n balls are randomly placed into n cells can be calculated as \((n-1)/n^n\).

Let's consider the scenario where n balls are randomly distributed into n cells. To determine the probability that exactly one cell remains empty, we need to calculate the number of favorable outcomes (arrangements where exactly one cell is empty) and divide it by the total number of possible outcomes.

The total number of possible outcomes is given by n^n since each ball has n choices (n cells) for placement, and there are n balls in total.

To calculate the number of favorable outcomes, we focus on the cell that remains empty. There are n choices for selecting the empty cell. For the remaining (n-1) cells, each ball has n-1 choices for placement, as it cannot be placed in the empty cell. Therefore, the number of favorable outcomes is (n-1)*(n-1)*(n-1)*...*(n-1) (n-1 repeated n-1 times).

Dividing the number of favorable outcomes by the total number of possible outcomes, we obtain \((n-1)/n^n\) as the probability that exactly one cell remains empty when n balls are randomly placed into n cells.

The following is a detailed explanation of the answer to the problem:a. Θ(n^2) - The algorithm has a running time of n^2, so the worst-case and best-case running time is Θ(n^2).

Asymptotic notation is a mathematical method for explaining the performance of algorithms with respect to their input size. Function, class, and assertion are terms in the context of asymptotic notation. In this problem, we must determine the Θ(g(n)) class to which the function belongs for each function. The most straightforward g(n) should be used in the solution for each function. Finally, the assertion must be proven. The following is a detailed explanation of the answer to the problem:a. Θ(n^2) - The algorithm has a running time of n^2, so the worst-case and best-case running time is Θ(n^2).Proof: For all inputs greater than or equal to c, n^2 + 1 is less than or equal to n^2 + n^2 = 2n^2, and n^2 + 1 is greater than or equal to n^2. To prove Θ(n^2), we must show that the function is both O(n^2) and Ω(n^2). The result follows immediately from the definition of O and Ω.b. Θ(n^2) - The running time of the algorithm is O(n^2), but not Ω(n^2). As a result, the algorithm has a Θ(n^2) complexity class.Proof: We observe that 10n^2 + 7n + 3 is less than or equal to 10n^2 + 7n^2 + 3n^2 = 20n^2, and 10n^2 + 7n + 3 is greater than or equal to 10n^2. Therefore, we have shown that f(n) is O(n^2). Since there is no constant such that cn^2 is always less than or equal to 10n^2 + 7n + 3 for n > k, we can't prove that the function is Ω(n^2). Hence, we use the Θ notation to indicate that the function is of class Θ(n^2).c. Θ(n log n) - The class Θ(n log n) is that of the function.2nlg(n + 2) + (n + 2)2 lg2nProof: We can show that the expression is O(n log n) by setting c = 2 and k = 1, as follows: 2n log2(n + 2) + (n + 2)2 log22n ≤ 2n log2(2n) + (n + 2)2log2(2n)  = 2n log2 n + 2n + 2(n log2 2)  + (n + 2)(2n log2 2) ≤ 6n log2 n  Since 2n log2(n + 2) + (n + 2)2 log22n is less than or equal to 6n log2 n, we know it is O(n log n). We can show that the expression is Ω(n log n) by setting c = 1/2 and k = 1, as follows: 2n log2(n + 2) + (n + 2)2 log22n ≥ 2n log2 n  ≤ 2n log2(n + 1)  ≥ cn log2 n  Thus, 2n log2(n + 2) + (n + 2)2 log22n is Ω(n log n). As a result, the class Θ(n log n) is that of the function.d. Θ(2^n) - The algorithm's running time is exponential, making it a member of the Θ(2^n) class.Proof: The function is exponential, as shown in the following equation: 2n + 1 + 3/(n - 1) > 2n + 1 for n > 4, thus 2n + 1 + 3/(n - 1) is Ω(2n). For n > 3, we have 2n + 1 + 3/(n - 1) ≤ 2 * 2^n. As a result, 2n + 1 + 3/(n - 1) is O(2^n). Therefore, the running time is Θ(2^n).e. Θ(log n) - The algorithm has a logarithmic running time, making it a member of the Θ(log n) class.Proof: We may establish that the function is O(log n) using the following expression:⌊log2n⌋ ≤ log2n. Because the ceiling of log2 n is less than or equal to log2 n, we know that the algorithm's running time is O(log n). We can prove that the function is Ω(log n) by setting c = 1 and k = 2, as follows: ⌊log2n⌋ ≥ log2n/2  = log2 (n/2) ≥ c log2 n Because ⌊log2n⌋ ≥ log2n/2 for n > 1, we have shown that the running time is Ω(log n). As a result, the running time is Θ(log n).

the 165 different committees are possible in combination.

What is combination?

If the order of the selections is unimportant, a combination is a mathematical choice made from a collection of various elements (unlike permutations). An apple and a pear are just one of three conceivable combinations if three fruits, such as an orange, an apple, and a pear, are provided. A k-combination of a set S is, technically speaking, a subset of the k distinctive elements of S. Alternatively said, two combinations are identical if and only if they have the same members. (How each set's members are ordered is not crucial.) the number of k-combinations given a set of n elements

That would be equal to the Combinations of 11 items taken 3 at a time.

C(n , k) = n!/[k!(n - k)!]

= 11!/[3!*(11 - 3)!]

= 11!/(3!*8!)

= 11*10*9/3*2

We square the residuals when using the least-squares line method to find the line of best fit because we believe that huge negative residuals (i.e., points well below the line) are just as harmful as large positive residuals (i.e., points that are high above the line).

We treat both positive and negative disparities equally by squaring the residual values.  We cannot discover a single straight line that concurrently minimizes all residuals. The average (squared) residual value is instead minimized.

We might also take the absolute values of the residuals rather than squaring them. Positive disparities are viewed as just as harmful as negative ones under both strategies.

6(20+4) is the equivalent to 6(24) using the distributive property.

The distributive Property states that it is necessary to multiply each of the two numbers by the factor before performing the addition operation when a factor is multiplied by the sum or addition of two terms. This property states that multiplying the total of two or more addends by a number will produce the same outcome as multiplying each addend by the number separately and then adding the results together.

In other words, an expression of the type

A (B + C) can be resolved as A (B + C) = AB + AC in accordance with the distributive property.

This characteristic also holds for subtraction.

A(B-C) = AB-AC

given that 6(24)

now compare the 6(24) with general form of distribution property a(b+c) = ab + ac

a = 6 and b+c = 24

Consequently, we must identify two integers the sum is 24.

These numbers 20 and 4 are suitable.

so,

6(20+4) = 6(20) + 6(4)

144 = 144

Hence, the 6(20+4) is the equivalent to 6(24) using the distributive property.

Answer:

A. -1/5

B. 8 gallons

C. 75 miles driven

Step-by-step explanation:

Part A is essentially just asking for the slope, which is written as a fraction with the numerator being the number of units the line goes up/down and the denominator being the number of units the line goes left/right. Because the line is going down from left to right, the slope is negative. The slope is -1/5.

Part B can be answered by simply looking at the graph and seeing where the line is at above 175 miles, which is 8 gallons.

Part C can be answered in the same way as Part B, by looking at where the line is at when level with 12 gallons, which is 75 miles driven.

The directional derivative of the function g(x, y, z) = xye^4z at point p(5, 20, 0) in the direction of pq can be found using the gradient. The directional derivative is equal to the dot product of the gradient of the function at point p and the unit vector in the direction of pq. The directional derivative of the function g(x, y, z) = xye^4z at point p(5, 20, 0) in the direction of pq is -200/√425.

To find the gradient of g(x, y, z), we need to compute the partial derivatives with respect to each variable:

∂g/∂x = ye^4z
∂g/∂y = xe^4z
∂g/∂z = 4xye^4z

Evaluating these partial derivatives at point p(5, 20, 0), we have:

∂g/∂x = 20e^0 = 20
∂g/∂y = 5e^0 = 5
∂g/∂z = 4(5)(20)e^0 = 400

The directional derivative in the direction of pq is given by the dot product of the gradient and the unit vector in the direction of pq. The unit vector in the direction of pq is obtained by normalizing the vector pq, which is (0 - 5, 0 - 20, 0 - 0) = (-5, -20, 0). Normalizing this vector gives us (-5/√425, -20/√425, 0).

Taking the dot product of the gradient (20, 5, 400) and the unit vector (-5/√425, -20/√425, 0), we have:

Directional derivative = (20)(-5/√425) + (5)(-20/√425) + (400)(0) = -100/√425 - 100/√425 = -200/√425.

Therefore, the directional derivative of the function g(x, y, z) = xye^4z at point p(5, 20, 0) in the direction of pq is -200/√425.
