What is the distance between the points (3,-7) and (6,2)
kotykmax [81]

Answer:

Step-by-step explanation:

Use the distance formula to determine the distance between the two points.

Distance

=√(x2−x1)2+(y2−y1)2

Substitute the actual values of the points into the distance formula.

√(2−(−3))2+((−6)−(−7))2

Simplify.

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.

PLEASE HELP ASAP!! ILL GIVE BRAINLIEST IF CORRECT
Natalka [10]

Answer:

Function 1 has a greater Y intercept than that of function 2

Step-by-step explanation:

Y intercept can be found by replacing x by 0 or

x = 0 0f the given function.

in this case Function 1 has a Y intercept of 5 when x =0

on the other hand, function 2 crosses the y axis once at -1 which is the y intercept.

you can now clearly see that

y = 5 > y = -1

---> 5>-1

so that's why we conclude that 1 has a greater Y intercept.

at a certain time of day, a 40 foot building casts a 8 foot shadow. how tall is a person who casts a 2 foot shadow?
lions [1.4K]
40 feet = 8 foot shadow

So in order to go from 40 to 8 you divide by 5.
 So if you have a person who casts a 2 foot shadow, you have to multiply by 5.

Your answer would be 10 feet.
Hope I helped :)
