Step-by-step explanation:

Slope of line ST = Slope of line PQ = -3.

y = -3x + c

When x = 3, y = -1

=> (-1) = -3(3) + c, c = 8

Therefore the equation of line ST is y = -3x + 8 and the y-intercept is 8.

Step-by-step explanation:

Hey there!

The given equation of line PQ is :

y = -3x -12.

Comparing the equation with y = mx + c. We get;Slope (m1)= -3

We know the condition of parallel lines is slope of 1st line = slope of 2nd line. (i.e m1=m2).

Therefore, slope of PQ= slope of ST = -3.

Now, The point through which ST passes is (3,-1) and we found its slope as -3.

So, let's use one point formula.

$(y - y1) = m2(x - x1)$

$(y + 1) = - 3(x - 3)$

$y + 1 = - 3x + 9$

$y = - 3x + 8$

Comparing the equation with y = mx+c. We get y-intercept is "8".

Therefore, y-intercept is "8".

Answer:

B, E

Step-by-step explanation:

There are a few ways to check for common denominator.

Here is one method

Take the 4 and 10 and see if both numbers will go into the numbers evenly. If they do, it is a common denominator

Will 4 and 10 divide evenly into 10 ?

4 will not go into 10 evenly

10 is not a common denominator.

Will 4 and 10 divide evenly into 20?

4 will go into 20 evenly. 20 /4 = 5

10 will go into 20 evenly 20 / 10 = 2

So 20 is a common denominator

Will 4 and 10 divide evenly into 24?

4 will go into 24 evenly 24 / 4 = 6

10 will not go into 24 evenly

24 is not a common denominator

Will 4 and 10 divide evenly into 32?

4 will go into 32 evenly 32 / 4 = 8

10 will not go into 32 evenly

32 is not a common denominator

Will 4 and 10 divide evenly into 40?

4 will go into 40 evenly 40/4 = 10

10 will go into 40 evenly 40 / 10 = 4

40 is a common denominator

What is the common difference of the sequence below?

vagabundo [1.1K]

Answer:

Step-by-step explanation:

In finding the COMMON DIFFERENCE, subtract the 2nd term and the first term.

a1 = -4

a2 = -2

Let "d" representing the COMMON DIFFERENCE.

d = -2 -(-4)

d = -2 + 4

d = 2

ANSWER:

THE COMMON DIFFERENCE OF THIS SEQUENCE IS 2

Why do you think rates are usually written as unit rates?

PSYCHO15rus [73]

A rate is a ratio of two quantities: miles per hour, calories per cookie,dollars per person, ... a unit rate just specifies the units (miles, hours) of the two quantities.

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:

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.

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.
