Step-by-step explanation:

The statistical decision based on the reported results of the hypothesis test is that the null hypothesis was rejected at the α = .05 significance level.

The t-value reported is 2.38, and the degrees of freedom are 21. This suggests that the test was likely a t-test with an independent samples design, where the sample size was n = 22 (since df = n - 1).

The p-value reported is less than .05, which indicates that the probability of obtaining the observed results, or results more extreme, under the assumption that the null hypothesis is true, is less than .05. Therefore, the null hypothesis is rejected at the .05 significance level in favor of the alternative hypothesis.

In conclusion, the statistical decision is that there is sufficient evidence to suggest that the population means are not equal, and the sample size was 22. However, we do not have information about the direction of the effect (i.e., whether the difference was positive or negative).

The value of mean is 59.8 and the variance of the sampling distribution is 1440.46

Given,

In the question:

The distance X is measured in miles and the sampling distribution of X is given by;

X :-      0        10    50     100

P(X) : - 1 /12    1/6   1/3    5/12

Calculate the mean and variance of this sampling distribution.

Now, According to the question:

The variance of a random variable provides an idea of the dispersion of the random variable with respect to its hope. It is then defined as shown in the image.

Then you first calculate E [x] and E [\(x^{2}\)], and then be able to calculate the variance.

E[x] = 0 × 1/12 + 10 × 1/6 + 50 × 1/3 + 100 × 5/12

E[x] = 1.6 + 16.6 + 41.6

Mean/ E[X] = 59.8

So E[X]²= 59.8² = 3576.04

On the other hand

E[\(x^{2}\)] = \(0^2\) × 1/12 + \(10^2\) × 1/6 + \(50^2\) × 1/3 + \(100^2\) × 5/12

E[\(x^{2}\)] = 0 + 16.6 + 833.3 + 4166.6

E[\(x^{2}\)]  = 5016.5

Then the variance will be:

Var[x]=  E[\(x^{2}\)]  - E[X]²

Var[x] =  5016.5 - 3576.04

Var[x] = 1440.46

Hence, The value of mean is 59.8 and the variance of the sampling distribution is 1440.46

Answer:

14,100.03 (just finished a test with this question and got it correct)

The car is worth about $14,100.03 after the second year.

The depreciation rate is the percentage rate at which an asset is depreciated over its projected useful life.

If a car depreciates at a rate of 24.9% annually, then its value at the end of each year is 75.1% of its value at the beginning of the year (100% - 24.9% = 75.1%).

After the first year, the car's value is:

$25,000 × 0.751 = $18,775.00

After the second year, the car's value is:

$18,775.00 × 0.751 = $14,100.03

Therefore, after the second year, the car is worth about $14,100.03.

The magnitude of the vector sum (A + B) is approximately 4.974.

To find the magnitude of the vector sum (A + B), we need to add the corresponding components of vectors A and B and then calculate the magnitude of the resulting vector.

Given:

Vector A: (5.1, 0)

Vector B: (-2.6, -4.3)

To find the vector sum (A + B), we add the corresponding components:

(A + B) = (5.1 + (-2.6), 0 + (-4.3))

= (2.5, -4.3)

Now, let's calculate the magnitude of the vector (2.5, -4.3):

Magnitude = sqrt((2.5)^2 + (-4.3)^2)

Jorge is wrong because he is using the wrong method to calculate the number of cars needed. When dividing 22 by 4, the result is not 5 with a remainder of 2, but rather 5 with a remainder of 2.

What is an example of a unitary method?

The term "unitary" refers to a single or separate unit. As a result, this strategy's objective is to establish values in terms of a single unit. For instance, if a car travels 44 kilometres on two litres of gas, the unitary technique can be used to determine how many kilometers it will drive on one.

To find the number of cars needed to transport the remaining passengers, we can use the following method:

Divide the number of remaining passengers by the capacity of each car to find the number of full cars needed: 22 passengers / 4 passengers per car = 5.5 cars

Round up to the nearest whole number to find the total number of cars needed: 6 cars

Answer:

The explicit formula for the geometric sequence is \(c(n) = -40\cdot \left(\frac{1}{2} \right)^{n-1}\).

Step-by-step explanation:

By definition of geometric sequence, we should use the following expression:

\(c(n) = c_{1}\cdot r^{n-1}\), \(n \ge 1\) (1)

Where:

\(c_{1}\) - First term.

\(r\) - Geometric rate.

\(n\) - Position of the element within the series.

If we know that \(c_{1} = -40\) and \(r = \frac{1}{2}\), then the explicit formula for the geometric sequence is:

\(c(n) = -40\cdot \left(\frac{1}{2} \right)^{n-1}\)

The explicit formula for the geometric sequence is \(c(n) = -40\cdot \left(\frac{1}{2} \right)^{n-1}\).

b) Data set (ii) has the largest mean and mode, but the smallest median and the largest standard deviation.

(a) The data set that has the greatest sample standard deviation is Data set (ii).

The sample standard deviation is a measure of the amount of variation or dispersion of a set of data values.

In this case, Data set (ii) has more entries that are farther away from the mean, which results in a larger standard deviation.

(b) The data sets are the same in terms of containing the same numbers (11, 12, 13, 14, 15, 16, and 17).

a. The degree of the polynomial is 6.

b. Factoring the equation, we have:

x6 - 49x^4 = x^4(x^2 - 49) = x^4(x - 7)(x + 7)

a.The degree of the polynomial equation x^6 - 49x^4 = 0 is 6. This is determined by the highest exponent of x in the polynomial, which is 6.

b. The two roots of multiplicity 1 can be found by factoring the equation as x^4(x^2 - 49) = 0. Setting each factor equal to zero, we have x^4 = 0 and x^2 - 49 = 0.

From x^4 = 0, we find the root x = 0 with multiplicity 4.

From x^2 - 49 = 0, we get (x - 7)(x + 7) = 0. Therefore, the roots x = 7 and x = -7 each have multiplicity 1.

In summary, the equation x^6 - 49x^4 = 0 has a degree of 6, and the roots with multiplicity 1 are x = 0, x = 7, and x = -7.

So the roots of the equation are:

The length of third side is in between 33.33 and 132.83.

The theorem that the sum of any two sides of a triangle is greater than or equal to the third side is known as the triangle inequality in Euclidean geometry. The theorem basically states that a straight line defines the shortest distance between two points.

Other metric spaces, or spaces that contain a means of measuring distances, have counterparts to the triangle inequality.

Given two sides of triangle are 33.33 yards and 99-100 yards(say 99.5)

There is a triangle here. Since it is not a right triangle, we must employ triangle inequality to determine the third side's length.

The longer side, 99.5 yards must be shorter than the sum of the other two sides. If the second side is c, then

99.5 < 33.33 + c.

The side c must be longer than 33.33

The side c must be shorter than the sum of the other two sides:

c < 99.5 + 33.33.

c < 132.83

Combining both we will get that

33.33  <  c  <  132.83.

This interval (33.33, 132.83) gives all the lengths the third side of the triangle can have.

Hence the length of third side varies between 33.33 and 132.83.

Step-by-step explanation:

If you find the x-intercepts, you'd solve (2-3x)/x = 0. This means you'd really solve 2-3x=0, which gives you x=3/2.

So the graph must have an x-intercept at (1.5, 0). Only f(x) has that.

\(y=\frac{2-3x}{x}\)

Vertical asymptote\(\Rightarrow x=0\)

\(2-3x=0\\\Rightarrow 3x=2\\\Rightarrow x=\frac{2}{3}\)

Mean:The mean is the sum of all the data values divided by the total number of data values. So, we can use the following formula to calculate the mean:

Mean = (sum of all the data values) / (total number of data values)Sum of all the data values = 55 + 56 + 70 + 61 + 53 + 57 + 50 + 73 + 52 + 69 + 2 = 598Total number of data values = 11

Therefore,Mean = (sum of all the data values) / (total number of data values) = 598 / 11 = 54.36 (rounded to two decimal places)Therefore, the mean of the given data values is 54.36.

Median:The median is the middle value of a sorted data set. Since the data set has 11 data values, the median is the average of the 6th and 7th values (counting from smallest to largest).

Therefore, the median is :Median = (55 + 56) / 2 = 55.5Therefore, the median of the given data values is 55.5.

Mode:The mode is the data value that appears most frequently in the data set. In this case, there is no data value that appears more than once. So, there is no mode.
