The range of the data set are

{10.2, 3.8, 21.9, 33.4, 31.8, 17.2} = 29.6

{0.5, 0.65, 0.22, 0.11, 0.47, 0.55, 0.55, 0.71} = 0.6

{6, 2, 14, 11, 28, 10, 19, 15, 11} = 26

The first data set is

{10.2, 3.8, 21.9, 33.4, 31.8, 17.2}

The range is the difference between the highest value and the smallest value

The highest value = 33.4

Lowest value = 3.8

The range = 33.4 - 3.8

= 29.6

The second data set is

{0.5, 0.65, 0.22, 0.11, 0.47, 0.55, 0.55, 0.71}

The highest value = 0.71

Lowest value = 0.11

The range = 0.71 - 0.11

= 0.6

The third data set is

{6, 2, 14, 11, 28, 10, 19, 15, 11}

Highest value = 28

Lowest value = 2

The range = 28 - 2

= 26

Therefore, the range of the each data set has been found

The volume of the cone is 144π units³.

The volume of a cone can be calculated as follows:

volume of a cone = 1 / 3 πr²h

where

Therefore, the height of the cone is 27 units and the radius of the cone is given as 4 units.

Let's find the volume using the formula,

r = 4 units

h = 27 units

Therefore,

volume of a cone = 1 / 3 πr²h

volume of a cone = 1 / 3 × π × 4² × 27

volume of a cone = 1 / 3 × π × 16 × 27

volume of a cone = 432 / 3 π

Step-by-step explanation:

The side lengths satisfy the Pythagorean theorem.

The sequence  is f(n)=3[tex]n^{2}[/tex]−n.

Sequences are ordered collections of numbers, often known as "terms," such as 2,5,8. There are some sequences that adhere to a particular pattern that allows for endless extension. For instance, 2,5,8 adheres to the "add 3" pattern, thus we may now continue the process. There are formulae for sequences that show us where to locate any given term.

We have 2 10 24 44 70 (which we refer to as the first column)

If we have 10 - 2 = 8, 24- 10 = 14, 44- 24 = 20, and 70- 44 = 26,

(this is second column)

The third column is now 14 - 8 = 6, 20 - 14 = 6, and 26 - 20 = 6.

First, create the second column sum formula.

Sum(x)

S(x)=8+6(x1)=6x+2 is the second digit of the phrase.

Next make the first column formula f(n)

f(n)= 2+[tex]sum_{n-1}[/tex]

=2+(n−1)[3(n−1)+5]

=2+(n−1)(3n−3+5)

=2+(n−1)(3n+2)

The scatter plot for provide data is shown above in figure. The slope-intercept form of the equation of the line that best fits the data is

y = - 0.3319 x + 312.16

Scatter charts are similar to line charts in that they use horizontal and vertical axes to represent points of data. However, they have a very specific purpose. The scatterplot shows how much one variable is influenced by another. The relationship between two variables is called their correlation. There are three types of correlation: positive, negative, and none (no correlation).

• Positive correlation: when one variable increases, the other also increases. ...

• Negative correlation: an increase in one variable causes a decrease in the other variable. ...

• No Correlation: nothing displayed

We have the following observations,

Now , we construct a scatter plot for the provide data. The constructed scatter plot is shown above. As we see in plot that there is no increase or decrease with increasing values of one variable .So, there is no correlation between two variables. Now, equation of the line that best fits the data, A best line of fit never connect all the points on the scatter plot. but it connects only a few points.

(a) Probability that sample mean lies between 79 and 81 is 0.9946.

(b) It is 0.04% likely is it that the sample mean diameter exceeds 81 when n = 36.

We are given that the metal sheets of a particular type, its mean value and standard deviation are 85 GPA and 2.3 GPA, respectively.

Suppose the distribution is normal.

Let X = sample mean diameter

The z-score probability distribution for sample mean is given by;

                                Z  =  (X - μ) / (σ / √n)

where,

μ = population mean = 85 GPA

σ = standard deviation = 2.3 GPA

n = sample size = 25

(a) Probability that sample mean lies between 79 and 81 is given by

= P(79<X<81) = P(X<81) - P(X≤79)

P(X<81) = P {(X - μ) / (σ / √n) < (81 - 85) / (2.3 / √25) = P(Z < 2.78) = 0.9973

P(X<79) = P {(X - μ) / (σ / √n) < (79 - 85) / (2.3 / √25) = P(Z < 2.78) = 0.0027

The above probability is calculated by looking at the value of x = 2.78 in the z table which has an area of 0.9973.

Here, P(79 < X < 81) = 0.9973 - 0.0027 = 0.9946

(b) Probability that the sample mean diameter exceeds 81 when n = 36 is given by = P(X > 81)

P(X<81) = P {(X - μ) / (σ / √n) < (81 - 85) / (2.3 / √25) = P(Z < 3.33) = 0.0004

The above probability is calculated by looking at the value of x = 3.33 in the z table which has an area of 0.9996.

Therefore, probability that sample mean lies between 79 and 81 is 0.9946 and it is 0.04% likely is it that the sample mean diameter exceeds 81 when n = 36.

Answer: A

Step-by-step explanation:

Our given equation is: y = -2x - 8

In order to have an equation with infinitely many solutions, it needs to be the same as the given equation.

Look at the answer choices:

A) y = -(2x + 8) = -2x - 8

This is the exact same equation, which means that any solutions for the given will also be solutions for this one. That means there will be infinitely many solutions.

B) y = -2(x - 8) = -2x + 16

We can tell this is definitely not the same as the given, so eliminate.

C) y = -2(x - 4) = -2x + 8

Again, this has a +8 instead of -8, so it's not the same and wrong.

D) y = -(-2x + 8) = 2x - 8

Here, we have positive 2 as the slope instead of -2, so it's not the same and wrong. Thus, the answer is A.

In linear regression, the most typical type of regression analysis, the line (or a more complicated linear combination) that most closely matches the data in terms of a given mathematical criterion is found.

When using the ordinary least squares method, for instance, the specific line (or hyperplane) that minimizes the sum of squared differences between the genuine data and that line is computed (or hyperplane).

c) The p-value is of 0.0013, representing the probability of finding a sample proportion of at least 55%.

At the null hypothesis, it is tested if there is not enough evidence that a majority of the population supports the measure, hence:

At the alternative hypothesis, it is tested if there is enough evidence that a majority of the population supports the measure, hence:

[tex]H_1: p > 0.5[/tex]

In which:

The values of these parameters in this problem are given as follows:

Then the test statistic is calculated as follows:

z = (0.55 - 0.5)/0.0167 = 2.99.

We have a right-tailed test, as we are testing if the mean is different of a value, hence the p-value represents the probability of finding a sample proportion of at least 0.55.
