Sample variance (Round to one decimal place as needed.) What do the results tellus? O A Jersey numbers on a football team vary much more than expected

Answers

Answer 1

Given the sample data: 58, 80, 36, 52, 06, 22, 23, 40, 66, 64, and 54Range:The range is the difference between the maximum and minimum values in a dataset. Therefore, range = maximum value - minimum value Range = 80 - 6 = 74Thus, the range is 74.

Variance: Variance is the average of the squared differences from the mean. The formula for variance is: $s^2 = \frac{\sum(x-\bar{x})^2}{n-1}$Here, the sample size (n) is 11. So, we have:$\bar{x}=\frac{1}{n} \sum_{i=1}^{n} x_{i}$where $x_i$ represents the ith observation in the sample.  

Thus,$\bar{x}=\frac{1}{11}(58 + 80 + 36 + 52 + 6 + 22 + 23 + 40 + 66 + 64 + 54)$$= \frac{461}{11}$$= 41.9091$Using the formula,$s^2 = \frac{(58-41.9091)^2 + (80-41.9091)^2 + (36-41.9091)^2 + (52-41.9091)^2 + (6-41.9091)^2 + (22-41.9091)^2 + (23-41.9091)^2 + (40-41.9091)^2 + (66-41.9091)^2 + (64-41.9091)^2 + (54-41.9091)^2}{11-1}$$= 821.553$Therefore, the variance is 821.553.

Sample Standard Deviation:

Standard deviation is the square root of variance. So, $s = \sqrt{s^2} = \sqrt{821.553}$$= 28.658$Therefore, the sample standard deviation is 28.658.The results suggest that the jersey numbers on a football team vary more than expected.

if a is a 7×9 matrix, what is the smallest possible dimension of nul A?
a. 2
b. 7
c. 0
d. 9

Answers

If a is a 7×9 matrix, the smallest possible dimension of nul A is 2. The correct option is a.

The smallest possible dimension of the null space (also known as the kernel) of matrix A depends on the rank of the matrix.

The rank of a matrix represents the maximum number of linearly independent rows or columns it contains.

In this case, we have a 7×9 matrix.

According to the rank-nullity theorem,

the dimension of the null space is given by the difference between the number of columns and the rank of the matrix.

The smallest possible dimension of the null space would be:

Dimension of null space = Number of columns - Rank of matrix

Since the matrix A has 9 columns, the smallest possible dimension of the null space would be:

Dimension of null space = 9 - Rank of matrix

The rank of the matrix can vary. It can range from 0 (if the matrix is a zero matrix) to a maximum of 7 (if all rows are linearly independent). So, depending on the rank, the smallest possible dimension of the null space can be any value between 9 and 2.

Consider the following system of linear equations 3x X2 + X₂ 1 3x1 + 6x2 + 2x2 = 0 3x1 + 3x2 + 7x, = 4 (a) Find the first three iterations of the Gauss-Seidel method using x(0) = 0 (6)Find the first three iterations of the Jacobi's method using x( ) = 0

Answers

Gauss-Seidel Method:
Iteration 1:
Starting with x(0) = [0, 0], we can substitute the initial values into the system of equations:
3(0) + 1(0) + 3x₂(1) + 6x₂(0) + 2x₂(0) = 0 -> 3x₂ = 0
3(0) + 3x₂(1) + 7x₂(0) = 4 -> 3x₂ = 4

Solving these equations, we find x(1) = [0, 4/3].

Iteration 2:
Using the updated values from the previous iteration, we have:
3x₁(1) + x₂(0) + 3x₂(1) + 6x₂(4/3) + 2x₂(4/3) = 0 -> 3x₁ + 16x₂ = -16/3
3x₁(1) + 3x₂(1) + 7x₂(4/3) = 4 -> 3x₁ + 19x₂ = 16/3

Solving these equations simultaneously, we obtain x(2) ≈ [-16/15, 8/15].

Iteration 3:
Using the updated values from the previous iteration:
3x₁(-16/15) + x₂(8/15) + 3x₂(-16/15) + 6x₂(8/15) + 2x₂(8/15) = 0 -> 3x₁ + 32x₂ = -16/5
3x₁(-16/15) + 3x₂(8/15) + 7x₂(8/15) = 4 -> 3x₁ + 19x₂ = 16/3

Solving these equations, we find x(3) ≈ [-16/35, 16/35].

After three iterations of the Gauss-Seidel method using the given initial value x(0) = [0, 0], we obtain an approximate solution of x(3) ≈ [-16/35, 16/35].

Jacobi's Method:

Iteration 1:
Starting with x(0) = [0, 0], we can update each component separately:
x₁(1) = (0 - (1(0) + 3x₂(0)) / 3 -> x₁ = 0
x₂(1) = (4 - (3x₁(0) + 7x₂(0))) / 3 -> x₂ = 4/3

Hence, x(1) = [0, 4/3].

Iteration 2:
Using the updated values from the previous iteration:
x₁(2) = (0 - (1(0) + 3x₂(4/3)) / 3 -> x₁ ≈ -16/15
x₂(2) = (4 - (3x₁(0) + 7x₂(4/3))) / 3 -> x₂ ≈ 8/15

Therefore, x(2) ≈ [-16/15, 8/15].

Iteration 3:
Using the updated values from the previous iteration:
x₁(3) = (0 - (1(-16/15) + 3x₂(8/15)) / 3 -> x₁ ≈ -16/35

y"-10y'+25y = 30x +3

Answers

The given differential equation by undetermined coefficients is y'' - 10y' + 25y = 30x + 3. Its solution is as follows: Let us assume y = yh + yp where yh is the homogeneous solution and yp is the particular solution. To find the homogeneous solution, solve the following differential equation: y'' - 10y' + 25y = 0characteristic equation: r2 - 10r + 25 = 0(r - 5)2 = 0Thus, yh = c1e5x + c2xe5x

Now, let us find the particular solution by assuming the following particular solution: yp = Ax + B Substituting this into the differential equation: y'' - 10y' + 25y = 30x + 3 yields:-10A + 25B = 3, and0x + A = 30Solving for A and B: A = 30 and B = 15Thus, yp = 30x + 15Therefore, the general solution is:y = yh + yp = c1e5x + c2xe5x + 30x + 15, where c1 and c2 are arbitrary constants.

a sporting goods store received an order of 64 baseball caps, of which 16 were green. if 1 of the 64 caps is selected at random, what is the probability it will

Answers

The probability of selecting a green baseball cap from the order of 64 caps is 0.25 or 25%.

To calculate the probability of selecting a green baseball cap from the order of 64 caps, we can use the concept of probability.

Given:

Total number of caps (n) = 64

Number of green caps (k) = 16

The probability (P) of selecting a green cap can be calculated as the ratio of the number of green caps to the total number of caps:

P(green cap) = k / n

Substituting the values:

P(green cap) = 16 / 64

P(green cap) = 0.25

Therefore, the probability of selecting a green baseball cap from the order of 64 caps is 0.25 or 25%.

Calculate the following operations on numbers: a) 4x2 + 3 + 6 - 2 + 7 X 2 b) 4+2-6-1 - 7+ 12 c) -48 - 12) = (-3 +11) d) (-5)(6)(-9)

Answers

a) the value of the expression is 29.

b) the value of the expression is -3.

d) the value of the expression is 270.

a) To calculate the expression 4x2 + 3 + 6 - 2 + 7 X 2, follow the order of operations (PEMDAS/BODMAS):

4x2 = 8
7 X 2 = 14

Now we can substitute these values into the expression:

8 + 3 + 6 - 2 + 14

Performing the addition and subtraction from left to right:

= 11 + 6 - 2 + 14
= 17 - 2 + 14
= 15 + 14
= 29

Therefore, the value of the expression is 29.

b) To calculate the expression 4+2-6-1 - 7+ 12, again use the order of operations:

4 + 2 = 6
-7 + 12 = 5

Now we can substitute these values into the expression:

6 - 6 - 1 - 7 + 5

Performing the subtraction and addition from left to right:

= 0 - 1 - 7 + 5
= -1 - 7 + 5
= -8 + 5
= -3

Therefore, the value of the expression is -3.

c) To calculate the expression (-48 - 12) = (-3 + 11), perform the subtraction and addition:

-48 - 12 = -60
-3 + 11 = 8

Now we can substitute these values into the equation:

-60 = 8

The equation is not true since -60 is not equal to 8. Therefore, there is no solution to this equation.

d) To calculate the expression (-5)(6)(-9), perform the multiplication:

(-5)(6)(-9) = -30(-9)
= 270

Therefore, the value of the expression is 270.

E. Permutations should be used because we make selections from a group of choices

Calculate how many different committees are possible

Answers

The correct answer is B. Permutations should be used because no item may be selected more than once, and the order matters. There are 720 different executive committees possible.

To determine the appropriate counting technique, we need to consider two factors: whether repetition is allowed and whether the order matters.

In this scenario, each position in the executive committee is distinct (mayor, deputy mayor, secretary, administrator, treasurer), and no member can hold multiple positions. Therefore, repetition is not allowed.

Additionally, the order of the positions in the committee matters. The committee will be different depending on who holds each position.

Based on these considerations, the correct answer is:

B. Permutations should be used because no item may be selected more than once, and the order matters.

To calculate the number of different committees possible, we can use the concept of permutations. Since there are six members in the city council and we need to select five for the committee, the calculation would be:

6P5 = 6! / (6-5)! = 6! / 1! = 6 * 5 * 4 * 3 * 2 * 1 / 1 = 720

Therefore, there are 720 different executive committees possible.
