Answer:
b. The student's scores on the posttest would have a smaller standard deviation.
Step-by-step explanation:
The first test is taken before the material is covered in class so we expect the standard deviation to be high because not everyone's scores would be lying close to the mean. Equal number of students mastered most, some or almost none of the material from reading the textbook based on the pretest result. this means the data is varying, so the standard deviation is large.
Whereas, after the teacher has taught the material and given the homework, they must have understood most of the material. The test they take after teaching as a post test. The results of the post test would have a smaller standard deviation as most of the students would have scored good. Hence, the student's scores on the posttest would have a smaller standard deviation.
If angles are the same, then their opposite edges also the same. So 2x-6 = x
If you solve it you will find x=6
We know that
if the volume of a prism <span>it was increased by a scale factor of 5
then
</span>the original volume is
multiplied by 5*5*5-------> 5³=125
therefore
the new volume compared with the original is 125 times larger
Answer: Its factored form will be
Step-by-step explanation:
Since we have given that
So, we need to factor ,
Now,
Now, by hit and trial method, we put n=1,
So, n-1 is also factor of p(n).
Now,
So, its factored form will be
I think it's -2 to -1 is the right answer maybe
but i hope it helps u !!
