Answer:
Step-by-step explanation:
5x² - 10x - 7 + 5x² + 8 = 5x² + 5x² -10x - 7 + 8
= 10x² - 10x + 1
Bring like terms together and add/ subtract the like terms
Answer:
The correct answer is option D. 4
Step-by-step explanation:
Points to remember
Opposite sides of the parallelogram are equal.
From the figure we can see that,AB and CD are opposite sides.
Therefore AB = CD
<u>To find the length of AB</u>
From the figure we get, AB = 4 units
Therefore CD = 4 units
<u>To find the x coordinate of point C</u>
y coordinate is -1
x coordinate is 4 units from point D
x coordinate of D is 0, therefore x coordinate of C = 0 + 4 = 4
The correct answer is option D. 4
The number of observations for each case in a t test for dependent samples is two is the correct answer.
In this question,
The dependent t-test also called the paired t-test or paired-samples t-test compares the means of two related groups to determine whether there is a statistically significant difference between these means. Each sample must be randomly selected from a normal population and each member of the first sample must be paired with a member of the second sample.
A dependent samples t-test uses two raw scores from each person to calculate difference scores and test for an average difference score that is equal to zero.
The groups contain either the same set of subjects or different subjects that the analysts have paired meaningfully. In dependent samples, subjects in one group do provide information about subjects in other groups.
Hence we c an conclude that the number of observations for each case in a t test for dependent samples is two is the correct answer.

Step-by-step explanation:
4x4x4x4x4x4=4^6
Group them to multiply to make it easier:
4x4=16
4x4=16
4x4=16
16x16x16=4096
honestly just plug it into a calculator
