The series of transformations that shows that parallelogram ABCD is congruent to parallelogram A'B'C'D' by superimposing one onto the other is a combination of translation and rotation that involves 150 degrees. A transformation refers to the process of changing an object's position, size, or shape.

Translation, reflection, rotation, dilation, and skew are the five basic transformation types that modify an object.In geometry, congruent shapes have the same shape and size. To superimpose one shape onto another means to make them coincide with each other.

The following series of transformations would show that parallelogram ABCD is congruent to parallelogram A'B'C'D' by superimposing one onto the other: Step 1: Translation. Translate the parallelogram ABCD by 5 units to the right and 6 units down to obtain parallelogram A1B1C1D1.Step 2: Rotation. Rotate parallelogram A1B1C1D1 by 150 degrees counterclockwise around point A1 to obtain parallelogram A2B2C2D2.Step 3: Translation. Translate parallelogram A2B2C2D2 by 8 units to the right and 3 units up to obtain parallelogram A'B'C'D'.Thus, the series of transformations that shows that parallelogram ABCD is congruent to parallelogram A'B'C'D' by superimposing one onto the other involves translation and rotation, with a rotation of 150 degrees.

To find:

The whether the value \(y=-1\) is a solution of the given inequality or not.

Solution:

We have,

\(7-2y>3y+13\)

It can be rewritten as

\(-2y-3y>13-7\)

\(-5y>6\)

Divide both sides by -5 and change the inequality sign.

\(y<\dfrac{6}{-5}\)

\(y<-1.2\)

All the value of y less -1.2 are the solutions of the given inequality but -1 is greater than -1.2.

The equation of the line perpendicular to y=-3x-1 that passes through the point (3,4) is y = (1/3)x + 3.

What do you mean by equation of line?

The slope of the line and a point on the line can be used to create the equation of a line. The slope of the line, which can be stated as a numeric integer, fraction, or the tangent of the angle it forms with the positive x-axis, is the line's inclination with respect to the positive x-axis.

The slope of the line given in the question is: -3,

The slope of perpendicular line is negative reciprocal of the slope of other line,

So,

The slope of perpendicular line is: 1/3.

The equation of the line is generally in the form:

y = mx + c

So, the equation of line becomes:

y = (1/3)x + c

We have given that the line passes through the point (3,4).

Putting the values of x and y in the above equation to get the value of c.

4 = (1/3)(3) + c

c = 3

Putting the value of c in the equation,

y = (1/3)x + 3

This is the required equation.

The correct answer is option D. No, because the sample sizes are not large enough to assume the distribution of the difference in sample means is approximately normal.Researchers investigated whether there is a difference between two headache medications, R and S.

Researchers measured the mean times required to obtain relief from a headache for patients taking one of the medications. From a random sample of 75 people with chronic headaches, 38 were randomly assigned to medication R and the remaining 37 were assigned to medication S. The time, in minutes, until each person experienced relief from a headache was recorded. The sample mean times were calculated for each medication.To construct a confidence interval, we require that some conditions are satisfied. The assumptions that should be met for inference with a confidence interval for the difference in population means are as follows:The data is independent;The data in each group should be roughly normally distributed;Both groups have the same variance, and each group should have a large enough sample size so that the central limit theorem (CLT) holds. The CLT holds for the difference in the sample means since both samples are taken from a population that is normally distributed. We can also assume that the sample size is large enough to use the t-distribution since each sample has more than 30 observations. As a result, all of the conditions have been met. As a result, we may employ a t-distribution to make inferences about the population difference between the two headache medications.

The probability of obtaining exactly two bad eggs without replacement is 2/55.

A certain cartoon of eggs has 4 bad and 8 good eggs.

The probability of obtaining exactly two bad eggs is 11/55. Let’s calculate: We are going to use the formula:

P(A and B) = P(A) × P(B|A)We are going to find the probability of selecting one bad egg first, followed by another bad egg in the second selection, and a good egg in the third selection.

P(Bad, Bad, Good) = P(Bad) × P(Bad|Bad) × P(Good|Bad, Bad)P(Bad, Bad, Good) = (4/12) × (3/11) × (8/10)P(Bad, Bad, Good) = 12/165P(Bad, Bad, Good) = 4/55.

This process can occur in any of the six different ways that two bad eggs and one good egg can be chosen.

Thus, we can multiply the probability of one of these processes by 6 to get the total probability of obtaining exactly two bad eggs.

P(exactly two bad eggs) = 6 × P(Bad, Bad, Good)P(exactly two bad eggs) = 6 × 4/55P(exactly two bad eggs) = 24/55.

Thus, the probability of obtaining exactly two bad eggs is 24/55. If the drawing is done without replacement, the probability of obtaining exactly two bad eggs will be slightly lower because the total number of eggs will decrease by one after each draw. After the first egg is drawn, there will be 11 eggs left in the box, 3 of which are bad and 8 of which are good. Therefore, the probability of drawing a bad egg on the second draw is 3/11. The probability of drawing another bad egg on the third draw is 2/10 because one of the bad eggs has already been drawn.

Therefore, the probability of obtaining exactly two bad eggs in this situation is: P(exactly two bad eggs without replacement) = (4/12) × (3/11) × (2/10) × 6P(exactly two bad eggs without replacement) = 1/165 × 6P(exactly two bad eggs without replacement) = 2/55.

The probability of getting two bad eggs from the cartoon is 0.3457 when three eggs are drawn without replacement. When the drawing is without replacement, the probability of getting two bad eggs from the cartoon is 0.3636.

What is probability?

Probability is the likelihood or chance of an event occurring. It is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. It ranges from 0 to 1, with 0 indicating impossibility and 1 indicating certainty.

Given,

Number of good eggs = 8

Number of bad eggs = 4

Total number of eggs in the cartoon = 8 + 4 = 12

(a)

Probability of obtaining exactly two bad eggs when three eggs are drawn without replacement from the cartoon:

We can solve this problem using the binomial probability formula.

\(P (X = k) = nCk * pk * (1 - p)n -k\),

where,n = number of trials

k = number of successes

p = probability of success

q = probability of failure

  = 1 - p

p = Number of bad eggs / Total number of eggs

    = 4 / 12

    = 1 / 3

q = 1 - p

   = (12 - 4) / 12

   = 8 / 12

    = 2 / 3

n = 3

k = 2

Using the above formula,

P (X = 2) = ³C₂ ×(1/3)² × (2/3)¹

              = 3 × (1/9) × (2/3)

               = 2/9

Therefore, the probability of obtaining exactly two bad eggs when three eggs are drawn without replacement from the cartoon is 0.222 or 0.22 (rounded to two decimal places).

(b)

Probability of obtaining exactly two bad eggs when three eggs are drawn with replacement from the cartoon:

When three eggs are drawn with replacement, the total number of possible outcomes = 12³

                                                                                                                                                 = 1728.

The number of ways to obtain exactly two bad eggs = ³C₂ ×4 × 8²

                                                                                        = 768

Therefore, the probability of obtaining exactly two bad eggs when three eggs are drawn with replacement from the cartoon is 768/1728 = 0.444 or 0.44 (rounded to two decimal places).

In half an hour, Ellie can cover 12 books.

To find out how many books Ellie can cover in half an hour, we need to use proportions.

We know that Ellie can cover 2 books in 5 minutes, so we can set up a proportion like this:
2 books / 5 minutes = x books / 30 minutes

Cross-multiplying and solving for x, we get:
5 minutes * x books = 2 books * 30 minutes
5x = 60
x = 12

So, Ellie can cover 12 books in half an hour.

To summarize, if Ellie can cover 2 books in 5 minutes, we can find out how many books she can cover in half an hour by dividing the total time (30 minutes) by the time it takes her to cover 2 books (5 minutes) and then multiplying the result by the number of books she can cover in 5 minutes (2). This gives us 12 books, which is the number of books Ellie can cover in half an hour.

A "threaded screw" or a "helical screw" is an inclined plane wrapped around a cylinder.  

This unique configuration allows screws to convert rotational motion into linear motion, making them essential components in various applications such as fastening objects, lifting loads, adjusting mechanisms, and transmitting power.

An inclined plane is a flat surface that is angled or tilted. It allows for easier movement of objects by reducing the force required to overcome vertical displacement. When this inclined plane is wrapped around a cylinder in a spiral or helical shape, it forms a threaded screw.

The calculation is not applicable in this case as it involves understanding the concept and structure of a threaded screw rather than performing numerical calculations.

An inclined plane wrapped around a cylinder is known as a threaded screw or helical screw.

Answer:

You have 3 pennies and your friend has 1 penny

Step-by-step explanation:

The given parameters are;

Let friend A = you

friend B = Your friend

The number of pennies with  friend A when he gives friend B 1 penny = Equal number of pennies between friend A and B

The number of pennies with friend A when he is given 1 penny by friend B = 2 times the number of pennies with friend B

Let the number of pennies with friend A = X and the number of pennies with friend B = Y, therefore, we have;

X - 1 = Y + 1.....................(1)

X + 1 = 2 × Y...................(2)

Subtracting equation (1) from equation (2), we get;

X + 1 - (X - 1) = 2·Y - (Y - 1)

X - X + 1 + 1  = 2·Y - Y + 1

2 = Y + 1

Y = 2 - 1 = 1

Y = 1

From equation (1), X - 1 = Y + 1 gives;

X - 1 = 1 + 1

X = 1 + 1 + 1 = 3

Friend A has 3 pennies and friend B has 1 penny.

Therefore, you have 3 pennies and your friend has 1 penny
