130 increases to 182, what percentage increase is this?

Option A and C have a proportional relationship.

What is proportional relationship?

Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportional relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of this constant.

(a) Total cost of buying x avocados be p

 So, p = 4x

(b) Let the total amount a taxi driver earns be y

So, y = 3 + m

(c) Let the total number of toys be x

So, x = 2w

(d) Let the total amount a Gardner earns be c

So, c = 10 + 15r

Hence, option A and C have a proportional relationship.

Add the scale factor to the x- and y-coordinates of a point on a coordinate plane with the center of dilatation at the origin.

Given,

Dilation;

Resizing an object is accomplished through a change called dilation. The objects can be enlarged or shrunk via dilation. A shape identical to the source image is created by this transformation. The size of the form does, however, differ.

We have to dilate a figure with a center of dilation;

Dilations centered at the origin;

On the coordinate plane, figures can be enlarged. The centre of dilatation is frequently used to be the origin. The points in the picture can be found by multiplying the coordinates of the preimage's points by the scale factor when distorting a figure that is centered at the origin.

That is,

On a coordinate plane with the center of dilatation at the origin, multiply the point's x and y coordinates by the scale factor.

After a comparison of females and males on the number of hours of a day that the subject watched the TV.

The hypotheses of a significance test to analyze whether the population means differ for females and males would be as follows:

(a) H0: μ1 = μ2 (the population means are equal for females and males)

Ha: μ1 ≠ μ2 (the population means are not equal for females and males)

(b) In order to conduct the significance test, we would need to calculate the t-statistic and the P-value. However, the question does not provide the necessary information to do so (e.g. sample means, standard deviations, sample sizes). Without this information, we cannot conduct the significance test and interpret the P-value.

(c) Without conducting the significance test, we cannot conclude anything about whether there is a gender difference in TV watching.

(d) Similarly, without conducting the significance test and calculating the confidence interval, we cannot determine whether the confidence interval would contain 0 or not.

Answer: The area is 12

Step-by-step explanation:

P=2l+2w

We are given, 

P=40in

l=2w-4

Plug these into the first formula and solve for the dimensions,

length and width, of the rectangle:

 40=2(2w-4)+2w       Simplify

40=4w-8+2w

40=6w-8

48=6w

8=w OR the width is 8 in, therefore, 

the length is

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.

The rationale underlying the use of projective personality tests, such as the Rorschach test and the thematic apperception test, is that they reveal the subjects' personalities by eliciting responses to vague, ambiguous stimuli.

The rationale underlying the use of projective personality tests, such as the Rorschach test and the Thematic Apperception Test, is that they can reveal a person's unconscious thoughts, feelings, and motivations. These tests use vague and ambiguous stimuli, such as inkblots or pictures, and ask the person to describe what they see or make up a story about the stimuli. The person's responses are believed to reflect their underlying personality traits and psychological conflicts.

Answer:

  $824.39

Step-by-step explanation:

You want to know the monthly deposit required for a 50-year ordinary annuity to accumulate enough value at 5% so that annual withdrawals can be made of $110,000 without affecting the principal.

In order for the annual interest to be $110,000 at 5%, you have ...

  I = Prt

  110,000 = P(0.05)(1)

  2,200,000 = P . . . . . . . multiply by 20

The value of the annuity must be $2.2M after 50 years.

In order for the annuity to have that future value, the monthly payment must be $824.39. This value can be found using a suitable financial calculator or spreadsheet. (Or the appropriate formula from your list.)

B (1,2) becomes (1,-2)

C ( 3,1) becomes (3,-1)

Then we proceed to rotate 90 degrees counterclockwise about the origin

Parallel slope intercept form is a form of linear equation that describes a line parallel to a given line with slope m.

The equation for a line parallel to the line with equation y = mx + b is y = mx + b + c, where c is any constant.

1. Start with the equation of the original line in slope-intercept form, y = mx + b

2. To make a parallel line, add a constant c to the y-intercept, so the equation is y = mx + b + c

She catches 90 frogs from the reservoir and marks them with a non-harmful dye.

Elanor then returns the frogs to the reservoir.

The next day she catches another 80 frogs and 10 of these are marked with the dye.

So on the first day the total frogs are 90.

On second day total frogs are 80 but 10 of them are dye, so the remaining are 70.

Therefore, the total frogs are 90 + 70 = 160.
