In univariate data, only one variable is assessed for each person. Two variables are measured for each person in bivariate data.

The definition of univariable data is "one variable," and it is generally understood to be one sort of data. It is one of the straightforward methods for data analysis. The data in univariable data only include one variable.

The cat's weight, for instance, is 10, 15, 25, 27, 30, 35, and 40.

The variable is hence "Cat weight."

The definition of bivariate data is "Two Variable," and it essentially consists of two different forms of data. It is a straightforward type of statistical analysis.

Only one variable is analysed at a time in univariate statistics. Two variables are compared in bivariate statistics. Multiple variables are compared using multivariate statistics.

In a bivariate analysis, the correlations between the two variables are measured. When there are more than two variables in the data set, a more complicated statistical analysis technique called multivariate analysis is utilized.

Therefore,

In univariate data, only one variable is assessed for each person. Two variables are measured for each person in bivariate data.

The t-distribution becomes flatter as the sample size increases.

The t distribution, compared to the z distribution, is more peaked for small samples but increasingly like the z distribution as n increases.

The t-distribution :

A t-distribution is a symmetric distribution that is similar to the standard normal distribution, also known as the z-distribution.

It is a continuous probability distribution that is used to estimate population parameters when the sample size is small (less than 30) or when the population standard deviation is unknown.

The t-distribution has more variability than the standard normal distribution due to the smaller sample size.

For a given number of degrees of freedom, the t-distribution has more density in the tails than the standard normal distribution.

The z-distribution :

The standard normal distribution is also known as the z-distribution. It is a continuous probability distribution that has a mean of zero and a standard deviation of one.

The z-distribution is bell-shaped, with a median of zero, a mode of zero, and a mean of zero.

In conclusion, the t-distribution has a peakier curve than the z-distribution, especially for small sample sizes.

However, as the sample size increases, the t-distribution approaches the z-distribution.

Answer:

a = -3

Step-by-step explanation:

Step 1:  Since we're told that 5 to the power of a = 1/125, we can use the following equation to solve for a:

5^a = 1/125

Step 2:  Take the log of both sides

log(5^a) = log(1/125)

Step 3:  According to the power rule of logs, we can bring a down and multiply it by log(5):

a * log(5) = log (1/125)

Step 4:  Divide both sides by log(5) to solve for a:

(a * log(5) = log(1/125)) / log(5)

a = -3

Optional 5:  We can check our answer by plugging in -3 for a and seeing if we get 1/125 when completing the operation:

5^-3 = 1/125

1/(5^3) = 1/125 (rule of exponents states that a negative exponent creates a fraction with 1 as the numerator and the base (5) and exponent (-3 becoming 3) as the denominator

1/125 = 1/125

Answer:

The total cost is $6.25

Step-by-step explanation:

3/4 of 1 kilo of rect

4/5 of 1 kilo of square

3/5 of 1 kilo of flower

rect = 3 per kilo

square = 3 per kilo

flower = 3 per kilo

First rectangle beads:

3x = y where x is number of kilos and y is full cost

3(3/4) = y

9/4 = y = 2 1/4 = $2.25

Second square beads:

3x = y where x is number of kilos and y is full cost

3(4/5) = y

12/5 = y = 2 2/5 = $2.20

Third flower beads:

3(x) = y where x is number of kilos and y is full cost

3(3/5) = y

9/5 = y = 1 4/5 = $1.80

Add costs together

1.80 + 2.20 + 2.25 = 6.25

The total cost is $6.25

The Laplace transform is used to solve the given second-order homogeneous differential equation. Applying the method, the solution is found to be y(t) = -e^t + 2e^(2t).

To solve the given second-order linear homogeneous differential equation using Laplace transforms, we first take the Laplace transform of the equation, solve for the Laplace transform of y, and then find the inverse Laplace transform to obtain the solution.

Given the differential equation:

y'' - 3y' + 2y = 0

Taking the Laplace transform of both sides of the equation, we get:

s^2Y(s) - sy(0) - y'(0) - 3(sY(s) - y(0)) + 2Y(s) = 0

Substituting the initial conditions y(0) = 1 and y'(0) = 0, the equation becomes:

s^2Y(s) - s - 1 - 3sY(s) + 3 + 2Y(s) = 0

Simplifying the equation, we have:

(s^2 - 3s + 2)Y(s) = s + 4

Dividing both sides by (s^2 - 3s + 2), we get:

Y(s) = (s + 4) / (s^2 - 3s + 2)

Now, we need to find the inverse Laplace transform of Y(s) to obtain the solution y(t). To do this, we factorize the denominator:

s^2 - 3s + 2 = (s - 1)(s - 2)

Using partial fraction decomposition, we can express Y(s) as:

Y(s) = A / (s - 1) + B / (s - 2)

Multiplying through by (s - 1)(s - 2), we have:

(s + 4) = A(s - 2) + B(s - 1)

Expanding and equating coefficients, we find:

A = -1

B = 2

Therefore, Y(s) = -1 / (s - 1) + 2 / (s - 2)

Taking the inverse Laplace transform, we get:

y(t) = -e^t + 2e^(2t)

Hence, the solution to the given differential equation is y(t) = -e^t + 2e^(2t).

The two parts of a rational number are the numerator and the denominator.

The numerator is the top number in a fraction, and it represents the number of parts being considered. The denominator is the bottom number in a fraction, and it represents the total number of equal parts into which the whole is divided. Together, the numerator and denominator define the value of the rational number, which is expressed as a ratio of two integers. For example, in the fraction 3/4, the numerator is 3 and the denominator is 4, so the rational number represents three out of four equal parts.

The question asks to find the inverse of a given function. To do this, we need to switch the roles of x and y in the function and solve for y. The resulting equation is the inverse function.

To find the inverse of a function, we need to switch the roles of x and y in the equation and solve for y. Let's take the function f(x) = 2x + 3 as an example.

1: Switch the roles of x and y in the function. We get x = 2y + 3.

2: Solve for y. Subtract 3 from both sides of the equation. We get x - 3 = 2y.

3: Divide both sides of the equation by 2. We get (x - 3)/2 = y.

4: Replace y with f^-1(x) to get the inverse function. We get f^-1(x) = (x - 3)/2.

Therefore, the inverse of the given function is f^-1(x) = (x - 3)/2.

= 13×12×11 / (3×2) = 13×2×11 = 286

there can be 286 different random samples of size 3.

The answer is 286.

The number of different simple random samples of size 3 that can be selected from a population consisting of 13 items is 286.Explanation:Simple random sampling is a statistical technique used in research. In this sampling method, a subset of a population is selected randomly, with each member of the population having an equal chance of being selected. There are different types of random sampling methods, such as systematic sampling, stratified sampling, cluster sampling, etc.The number of different simple random samples of size k that can be selected from a population of size N is given by the formula N!/k!(N-k)!, where ! denotes factorial. Here, the population consists of 13 items, and we need to find the number of different simple random samples of size 3 that can be selected from this population.So, the required number of different simple random samples of size 3 that can be selected from this population is 13!/3!(13-3)! = 286.

Therefore, the number of different simple random samples of size 3 that can be selected from a population consisting of 13 items is 286.

The best way to decompose the composite figure to determine its area is as a semicircle, a trapezoid, and two rectangles. This way, we can use the following formulas to find the area of each part:

Area of a semicircle = 21​πr2, where r is the radius of the circle.

Area of a trapezoid = 21​(b1​+b2​)h, where b1​ and b2​ are the bases and h is the height of the trapezoid.

Area of a rectangle = l×w, where l is the length and w is the width of the rectangle.

Then, we can add up the areas of each part to find the total area of the composite figure. The other options are not as convenient because they either involve more parts or more complicated shapes. For example, option A would require finding the area of a triangle, which involves using trigonometry or the Pythagorean theorem. Option B would require finding the area of four triangles, which is more tedious than finding the area of two rectangles. Option C would require finding the area of a square, which is redundant because a square is a special case of a rectangle.

Step-by-step explanation:

The composite figure can be decomposed into a semicircle, a trapezoid, and two rectangles.

Option D is the correct answer.

It is a quadrilateral that has one pair of parallel sides and a height.

The area is calculated as: 1/2 x sum of the parallel sides x height.

Examples:

Area of a trapezium that has the parallel sides as 3 cm and 4 cm and a heght o 5 cm.

Area = 1/2 x (3 + 4) x 5

Area = 1/2 x 7 x 5

Area = 35/2 = 17.5 cm^2

The expression for the transformed function is: y = √(x - 322) and

y = √(x + 2) - 9.

To determine the expressions for the transformed functions represented by the given graphs, we need to analyze the transformations applied to the square root function.

Graph 1: (322, 0)

Since the point (322, 0) is on the graph, it represents the vertex of the transformed function.

The square root function has a vertex at (0, 0), so there is a horizontal translation of 322 units to the right.

The expression for the transformed function is: y = √(x - 322)

Graph 2: (-2, -9)

Again, the given point (-2, -9) represents the vertex of the transformed function. The square root function has a vertex at (0, 0), so there is a horizontal translation of 2 units to the left and a vertical translation of 9 units downward.

The expression for the transformed function is: y = √(x + 2) - 9
