Answer:

Step-by-step explanation:

Answer:

(a) There are 2 groups. The treatment group will hear older students describe overcoming challenges. The control group won't hear anything.

Label each student with a different integer from 01 to 40. Go to a line in Table D and read two-digit groups moving from left to right. The first 20 different labels between 01 and 40 identify the 20 students who hear older students talking. The remaining 20 students don't hear anything. Ignore groups of digits from 41 to 00.

(b) Separate the 40 freshmen into 2 groups according to their history of academic performance. Carry out treatment separately in each block to account for the variation due to the history of academic performance.

Step-by-step explanation:

(a) We want to infer the cause and effect between hearing older students talking about their challenges and the students' academic performance.

Claim the 2 groups first;

Clarify the random assignment of people.

(b) The differences between the two kinds of students are expected to affect the response to the treatments in some ways. Randomized block designs are to eliminate the effect.

The relationship between p(a), p(b) and p(a > b) is that p(a) + p(b) - p(a > b) = 1, meaning the probability of having at least one of the two types of cards is equal to the sum of the individual probabilities minus the probability of having both.

A. No, it could not be the case that p(a > b) = 0.5. This is because

p(a) + p(b) = 1,

so p(a > b) = 1 - p(a) - p(b)

= 1 - 0.6 - 0.4

= -0.1, which is not a valid probability.

B. The probability that the selected student has at least one of these two types of cards is

p(a) + p(b) - p(a > b)

= 0.6 + 0.4 - 0.3

= 0.7.

C. The probability that the selected student has neither type of card is 1 - (p(a) + p(b) - p(a > b))

= 1 - 0.7

= 0.3.

D. The relationships among p(a), p(b), and p(a > b) can be summarized by the equation p(a) + p(b) - p(a > b) = 1. This equation states that the probability of having atleast one type of card is equal to the sum of the probabilities of having a Visa card and a Mastercard minus the probability of having both types of card.

suppose the average number of hours worked per week for high-school aged teens in the united states is 17 hours per week with a standard deviation of 4 hours. So, the number of people selected from the public for a research is known as a sample.

Data dispersion in regard to the mean is quantified by a standard deviation, or "σ". Data are said to be more closely grouped around the mean when the standard deviation is low and more dispersed when the standard deviation is high.

Because it makes measures easier to comprehend when the data is spread, standard deviation is significant. The data's standard deviation will increase as the data's distribution becomes more widely scattered. The deviation of each observed value from the mean is measured using this metric. The majority of data in any distribution will fall within a 2 standard deviation range of the mean.

For the given details the correct matching will be:

Parameter - 17 hrs per week

Population - All high-school-aged teens in the US

Statistic - 14.4 hours per week

Sample - 15 students

Population is everything that is taken into account for an experiment since parameters reflect population characteristics and statistics state sample parameters.

The required distance from the base of the lighthouse to the sailboat is 11 feet.

Let x be the distance from the base of the lighthouse to the sailboat.

We know that the angle of depression is 6° and the height of the observer is 104 ft. We can use the tangent function to find the ratio of the opposite side (x) to the adjacent side (104 ft).

tan(6°) = x / 104

To find x, we can multiply both sides by 104:

x = 104 × tan(6°)

x = 104 × 0.10510

x = 10.9308

x ≈ 11

The number of students who scored between 8181 and 8686 can be calculated using the z-score formula to find standard deviation.

z1 = (8181-7676)/55 = 1.89

z2 = (8686-7676)/55 = 3.04

Using a standard normal table, the area under the curve between these two z-scores is approximately 8.5%. So, we can estimate that about 850,085 students scored between 8181 and 8686. We find the z-score of 8181 and 8686 and calculate the area under the standard normal distribution curve between these z-scores.

A standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1, while a non-standard normal distribution has a different mean and/or standard deviation. The z-score formula is used to convert a non-standard normal distribution to a standard normal distribution, so that the properties of the standard normal distribution can be applied, such as using a standard normal table to find areas under the curve.

According to the formula of area of rectangle, the smallest perimeter possible to enclose this area is 60 and the length is 24 and the breadth is 6.

The general formula to calculate the area of rectangle is written as

A = l x b

And the perimeter of rectangle is written as.

P = 2(l + b)

Where l refers the length of the rectangle and b refers the breadth of the rectangle.

Here we know that the four-sided rectangular pen with an area of 144 square feet.

So, here we have to substitute the value of the formula, then we get,

=> l x b = 144

=> b = 144/l --------------------(1).

Here we have to substitute this one on the perimeter then we get,

=> 2(l + b) = 30

=> 2(144/l + l) = 30

=> 144/l + l = 15

=> l² - 15l + 144 = 0

When we factorize this one then we get the value of l as 24.

Then the value of the width is calculated as,

=> l = 144/ b

=> b = 144/24

=> 6

Then the perimeter us calculated as,

A graph when plotted, we get a straight line and it is called linear graph. Linear graph is a graph of linear function.

Domain refers to all the possible input values, it is the values in the x-axis of the graph. A range means all the output values, when each domain is used in a function. It is the y-axis values.

To determine the domain identify all the X- coordinates in the linear function graph. To determine the range, identify all Y-coordinates in the functions graph. The domain and range are usually represented as a set of values.

If the domain have values from 0-6, it is represented as {0<x<4}

If the range is values between -1 to 10, then it is represented as {-1<x<10}.

Lets consider the linear function y= 3x, the domain is between 0 and 10, and range above are,

Function  y= 3x

Domain  0    1      2    3     4     5       6        7         8        9        10

Range    0     3     6     9    12    15      18     21        24      27      30

Answer:

3rd choice

a rotation of 90° counterclockwise about the origin and a translation down 1 unit

Step-by-step explanation:

This is just asking you what operations you need to perform to get figure N from figure M. Such a set of operations is called a transformation.

In this case we see that to get figure N we have to rotate figure M 90° in a counterclockwise direction. That would be the first transformation

From the choices you can eliminate the first two choices which deal only with clockwise rotation

Translation transformation is one where the figure is shifted horizontally or vertically

All we have to do is figure out if, after 90° counterclockwise rotation of M whether it was shifted 1 unit up or 1 unit down

Look at the point (-3, 1) in figure M.

When a figure is rotated 90° counterclockwise, each if its original coordinates (x, y) become new coordinates (-y, x)

In other words the coordinates are interchanged in the transformed figure and the sign of the new x-coordinate is changed from the original y value

So (-3, 1) should become (-1, -3)

But in figure N, that point has become (-1, -4) which is (-1, -3-1). This indicates the figure has been shifted down which corresponds to a translation down by 1 unit

Answer: 3rd choice

a rotation of 90° counterclockwise about the origin and a translation down 1 unit

The two images I have attached may help you understand better. First one is just the rotation of M. Second one is the rotated figure shifted down which results in figure N

The curvature of the curve r(t) = (9t, t², t³) at the point (9, 1, 1) is (3/ 800)√(91/ 94).

The curvature of a curve at a given point is a measure of how much the curve is bending at that point. In order to find the curvature of a curve, we need to first find the unit tangent vector, the unit normal vector, and the unit binormal vector at the point in question.

Given r(t) = (9t, t², t³) at the point (9, 1, 1). Thus t = 1 at (9, 1, 1).

The unit tangent vector at the point (9, 1, 1) is given by the derivative of r(t) with respect to t, evaluated at t = 1

r'(t) = (9, 2t, 3t²)

so T(t) = r'(1) = (9, 2, 3)

The magnitude of T(1) = √(9² + 2² + 3²) = √(94)

The unit tangent vector at (9, 1, 1) is T(1) = (9/√(94), 2/√(94), 3/√(94))

The unit normal vector, N(1), is given by the derivative of T(1) with respect to t, evaluated at t = 1

T'(t) = (0, 2, 6t)

T'(1) = (0, 2, 6)

The magnitude of T'(1) = √(0² + 2² + 6²) = √(40)

The unit normal vector at (9, 1, 1) is N(1) = (0, 2/√(40), 6/√(40))

The unit binormal vector, B(1), is given by the cross product of T(1) and N(1)

B(1) = T(1) × N(1)

= (18/√(40×94), 6/√(40×94), -54/√(40×94))

|B| = (3/2)√(91/ 235)

Finally, the curvature, k, at the point (9, 1, 1) is given by the magnitude of T'(1)

[tex]k = \frac{|B|}{|T|^3}[/tex]

k = (3/2)√(91/ 235)/ (√40)³ = (3/ 800)√(91/ 94)
