Answer:

P_{R'J'M'}=36\ un.\\ \\A_{R'J'M'}=54\ un^2.

Step-by-step explanation:

Given:

A_{RJM}=6\ un^2.\\ \\P_{RJM}=12\ un.

If the triangle is dilated by a scale factor of k=3 centered at the origin, then

P_{R'J'M'}=k\cdot P_{RJM}=3\cdot 12=36\ un.\\ \\A_{R'J'M'}=k^2\cdot A_{RJM}=3^2\cdot 6=9\cdot 6=54\ un^2.

What is the slope of a line with the following points
mars1129 [50]
Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values.

To increase the value of estimated Cohen's d, a researcher increases the sample size. Will this change the value of d?
tatyana61 [14]

Answer:

a. A) Yes; as sample size increases, effect size increases.

b. A) The critical value increases.

Step-by-step explanation:

a.

If all possible samples of size N are drawn from a finite population, Np, without replacement, and the standard deviation of the mean values of the sampling distribution of means is determined then:

σx =d  √N

d = σx . √N

d ∞ N

from this, we can say d is directly proportional to √N

where σx is the standard deviation of the sampling distribution of  means and d is the standard deviation of the population’. The standard deviation of a sampling distribution of mean values is called the standard error of the means,

therefore, we can conclude that:

A) Yes; as sample size increases, effect size increases.

b.

In this estimate, tc is called the confidence coefficient for small samples,  d is the standard deviation of the sample, x is the mean value of the sample and N is the number of members in the sample.

When determining the t-value, given by

t =( (x−µ) /s) * \sqrt{N-1}

it is necessary to know the sample parameters x and s and the population parameter µ. x and s can be calculated for the sample, but usually an estimate has to be made of the population mean µ, based on the sample mean value.

from the above equation it can be deduced that t value is determined with the sample size, and as the sample size increases

A) The critical value increases.
