Answer: 2.25
Divide the corresponding values. You'll divide figure 2's length over figure 1's corresponding length. So 18/8 = 2.25
This means each side of figure 2 is 2.25 times larger than the corresponding side for figure 1
Answer:
the second one
Step-by-step explanation:
it does not say that both sides are parallel
To figure this out, always divide y by x in each table. All of the values have to be equal or the table isn’t proportional.
In this case, the last choice is proportional.
Answer:
The psychologist finds that the estimated Cohen's d is 0.583.
Step-by-step explanation:
The Cohen's d is used to calculate the effect size, appied when a null hypothesis is rejected.
It can be calculated for this case of population mean as:

The psychologist finds that the estimated Cohen's d is 0.583.
Hello!
We can go through the choices and see if they are true
Choice 1
A function has one output for every input
This is not a function because it has -1 as an output for both 4 and -1
This is the answer
------------------------------------------------------------------------------------------------------
Choice 2
The inputs are the x's
We see that the inputs are -1, 0, 3, and 4
This is true
------------------------------------------------------------------------------------------------------
Choice 3
The outputs are the y's
We see the outputs are -2, -1, and 1
This is true
------------------------------------------------------------------------------------------------------
Choice 4
We can follow the lines and see the relations are
(-1, 1), (0, -2), (3, 1), (4, -1)
This is also true
------------------------------------------------------------------------------------------------------
The only one that was false was the first choice so that is the answer
The answer is A) The diagram represents a function
------------------------------------------------------------------------------------------------------
Hope this helps!
