The correct option is A) With sample size 10, the tails of the curve of the t-distribution have more area than the tails of the curve of the z-distribution.

Explanation:Given:P(t > 1.96) = 0.0408P(t < -1.96) = 0.0408The t-distribution is different from the z-distribution because it has a thicker tail.The tail is thicker since the t-distribution is determined by the sample size, whereas the z-distribution is determined by the population size (the t-distribution is estimated with the standard error of the mean in this case).

A t-distribution with small degrees of freedom has a much thicker tail than a z-distribution with the same degrees of freedom. Because sample size is related to the degrees of freedom, it makes sense that t-distributions with smaller sample sizes will have thicker tails.

The population variance is replaced with the sample variance in the estimation of the t-distribution. As a result, the t-distribution has heavier tails than the z-distribution.

Step-by-step explanation:

Step 1: Setting Up the Factors

Our roots are 3, 2, and -4 so

our factors are

\((x - 3)(x - 2)(x + 4)\)

Step 2: Initial Test to see if the result equal 30

Let a be a constant, such we have

\(a(x - 3)(x - 2)(x + 4) = 30\)

Plug in. 1 for x.

\(a(1 - 3)(1 - 2)(1 + 4) = 30\)

\(a( - 2)( - 1)(5) = 30\)

\(a(10) = 30\)

\(a = 3\)

So our equation is

\(3(x - 3)(x - 2)(x + 4)\)

Or if you want it simplifed

\(3( {x}^{2} - 5x + 6)(x + 4) = 3( {x}^{3} + - {x}^{2} - 14x + 24) = 3 {x}^{3} - 3 {x}^{2} - 42x + 72\)

Standard deviation of the sampling distribution of the sample mean is 50.

We were asked to determine the mean of the sampling distribution of the sample mean. The mean score for a standardized exam is 400, the standard deviation is 50, and we have a random sample of 25 students. You take a sample of 25 students in total. You will obtain a sample average of X after averaging that sample. Take 70 student samples, then compute the mean.

The sampling distribution of the sample mean is the term used to describe how the mean varies from sample to sample. The question being posed here is, what is the mean of the sampling distribution of sample means?

Regardless of how the population distribution is shaped, the mean of sample averages is always the same as the mean of the population.

The sample mean is 400.

The spread of a data distribution is measured by standard deviation. The average distance between each data point and the mean is measured. Whether the data is being treated as a population unto itself or as a sample of a larger population will affect the standard deviation calculation formula.

So standard deviation of sample mean is also same as it is for random sample that is 50.

There are 118 adult tickets sold

This is because 354/3 =118

and 118+118=236

236 are the child tickets

therefore 118 are the adult tickets.

Hope this helped!

The total number of adult ticket sold is 118 tickets.

Let's write "x" to represent how many adult tickets were sold.

The information provided indicates that there were twice as many student tickets sold as adult tickets. The quantity of student tickets sold can therefore be stated as 2x.

There were 354 total tickets sold, which includes both student and adult tickets.

We may construct an equation based on the total number of tickets to resolve this issue:

x + 2x = 354

Combining comparable variables

3x = 354

x = 354 / 3

x = 118

Note that the system of linear inequalities represents Jackson's workout are given as follow:

1) The system of equations are:

x ≤ 45

xy ≥ 400

6.9 ≤ y ≤ 10.4


2) Where  x: the number of minutes Jackson spends exercising on the stair stepper

y: the number of calories he burns per minute on the stair stepper

Let's define two variables:

We want to write a system of linear inequalities to represent Jackson's workout on the stair stepper.

First, we know that Jackson can exercise for at most 45 minutes, so we have the inequality:

x ≤ 45

Next, we know that the number of calories burned per minute on the stair stepper depends on the intensity of the workout. Since Jackson wants to burn at least 400 calories, we can write:

xy ≥ 400

Finally, we need to determine the range of values that y can take. We know that Jackson is either doing a light effort or a vigorous effort on the stair stepper.

According to the information given in the problem, the stair stepper can burn a maximum of 10.4 calories per minute with a vigorous effort. So we have:

6.9 ≤ y ≤ 10.4

Putting it all together, the system of linear inequalities to represent Jackson's workout on the stair stepper is:

x ≤ 45

xy ≥ 400

6.9 ≤ y ≤ 10.4

Note that we can simplify the second inequality to x ≥ 400/y, but we'll leave it in the current form for clarity.

The equation of the sphere is:

(x - 1)² + (y + 1)² + (z - 2)² = (36 / sqrt(743))²

To find the equation of the sphere, we need to know the center and radius of the sphere.

Given equations of two intersecting planes:

z² + 7x - 27y + 2 = 0

2x + 3y + 4z - 8 = 0

By solving the system of equations formed by the two planes, we can find the line of intersection of the planes. The direction ratios of the line of intersection will give us the direction ratios of the normal vector to the sphere.

Solving the system of equations:

2x + 3y + 4z - 8 = 0 ...(2)

z² + 7x - 27y + 2 = 0 ...(1)

Multiply equation (1) by 2 and subtract it from equation (2):

-55x + 5y - 8z - 12 = 0

From this equation, we can find the direction ratios of the line of intersection of the two planes: (-55, 5, -8).

The center of the sphere will lie on this line, so we can take any point on this line as the center of the sphere. Let's choose a point on the line, for example, (1, -1, 2).

To find the radius of the sphere, we need to find the perpendicular distance from the center of the sphere to one of the intersecting planes. Let's find the perpendicular distance from the center (1, -1, 2) to the plane given by equation (1).

Using the formula for the distance between a point and a plane:

Distance = |z1 + 7x1 - 27y1 + 2| / sqrt(1^2 + 7^2 + (-27)^2)

Distance = |2 + 7(1) - 27(-1) + 2| / sqrt(1 + 7^2 + (-27)^2)

Distance = 36 / sqrt(743)

The radius of the sphere is the perpendicular distance, which is 36 / sqrt(743).

Therefore, the equation of the sphere is:

(x - 1)² + (y + 1)² + (z - 2)² = (36 / sqrt(743))²

Step-by-step explanation:

Please refer to the diagram below.

We are given that O is the center of the circle, and chords MN and RS are intersected a P. OP is the bisector of ∠MPR. And we want to prove that MN = RS.

We will construct segments OK and OJ such that it perpendicularly bisects MN and RS.

Since OP bisects ∠MPR, it follows that:

\(\displaystyle \angle JPO\cong \angle KPO\)

And since OK and OJ are perpendicular bisectors:

\(m\angle OKP=90^\circ \text{ and } m\angle OJP=90^\circ\)

Therefore:

\(\angle OKP\cong \angle OJP\)

By the Reflexive Property:

\(OP\cong OP\)

Therefore:

Influential scores, indicated by large residuals, have a significant impact on the regression line when removed from the data. These points, characterized by extreme x or y-values, can alter the slope and intercept of the regression line, emphasizing their importance in regression analysis.

The correct statements about influential scores are i and ii.

i. Influential scores have large residuals because they have a strong effect on the regression line. This means that if we remove an influential score from the data, it will significantly change the slope and intercept of the regression line.

ii. Removal of an influential score sharply affects the regression line because influential scores have a large impact on the regression line. If we remove an influential score, it will significantly change the slope and intercept of the regression line.

iii. This statement is not true. An x-value that is an outlier in the x-variable may be indicative of a point being influential, but a y-value that is an outlier in the y-variable can also be indicative of a point being influential.

To find the moles of gas remaining in the bag, we can use the initial and final volumes and the initial moles of gas. Since the temperature and pressure remain constant, we can use the formula:

Initial moles × Initial volume = Final moles × Final volume
0.80 mol × 18 L = Final moles × 16 L

Solve for the final moles:
(0.80 mol × 18 L) / 16 L = Final moles

14.4 mol / 16 L = Final moles
Final moles = 0.9 mol

To linear  transformation until vector is a linear combination of another we convert unit vectors i,j,k of one Cartesian coordinate system to unit vectors i’,j’, k’ .

Linear algebra is all about making transformations of linear combinations of numbers, called vectors, and arrays of vectors, called matrices. The elements of linear combinations can be added and multiplied together but may also represent more complex forms of transformation. Linear algebra proves to be of great importance for performing mathematical operations on voluminous data, so having a grasp of it is a must-have skill for a data scientist.

First let us convert unit vectors i,j,k of one Cartesian coordinate system to unit vectors i’,j’, k’ of another Cartesian coordinate system obtained by rotating the first system. We know that a vector remains invariant under rotation of coordinate system.

Now, let us write i in rotated system. i=x11′i’+x12′j’+x13′k’………………(1).

Similar equations for j and k can be written.

We take dot product on both sides of eq.(1) by i’. This gives,

i.i’=x11′, because i’.i’=1, j’.i’=k’.i’=0.

We can see that x11′=cos(i,i’).

We can find x12′=cos(i,j’) from Eq.(1) by taking dot product on both sides by j’.

For x13′ we take dot product by k’. This will give cos(i,k’)=x13′.

Similar treatment can be given for j and k. This will give nine elements of a 3X3 matrix x(n,m).

With this matrix we can find i,j,k, in terms of i’,j’,k’.

The width of the bookcase is 6 feet and height is 4 feet if the carpenter expects to use 28 feet of lumber to make it.

Let w = the width and h = the height of the bookcase. The width of the lumber you are using is not given.

Also, Let the height is x.

and, the width is 3x -14.

Since, we stated that this equals 28 feet and also that w = 3h - 14, we can insert this into the equation and use it to solve for h:

Now,

The total amount of lumber used to make the bookcase is:

L = 4w + 2h             -------------------------- (1)

Now Putting Width and height in the Equation (1):

⇒ 28 = 4(3h - 14) + 2h

⇒ 28 = 12h - 56 + 2h

⇒ 28 = 14h - 56

⇒ 84 = 14h

⇒ h = 84/14

      = 6 feet

Putting the value of height, h= 6 feet in

w = 3x -14

⇒ w = 3(6) - 14 = 4.

Therefore,

The width is 4 feet and the height is 6 feet.

Therefore, The smallest set of integers guaranteed to have a difference that is a multiple of 14 is 15. This is due to the Pigeonhole Principle and the 14 possible remainders when dividing integers by 14.

The smallest set of integers for which we are guaranteed there exist two whose difference is a multiple of 14 is 15. This can be explained by considering the possible remainders when dividing integers by 14. There are 14 possible remainders (0 to 13), but if we choose 15 integers, then by the Pigeonhole Principle, at least two of them must have the same remainder when divided by 14. The difference between these two integers will be a multiple of 14, as their remainders are the same. Therefore, the smallest set of integers required is 15.
