So the "sum" means to add all of the terms: 1³ + 2³ + 3³
1³ is simply 1
2³ is 8
3³ is 27
so, from there, you just add all of those terms: 1 + 8 + 27 = 36
<u>Answer:</u>
The correct answer option is C. 56.
<u>Step-by-step explanation:</u>
We are given that a group of 8 friends (5 girls and 3 boys) plans to watch a movie, but they have only 5 tickets.
We are to find the number of combinations these 5 friends could
possibly receive the tickets.
Here, we will use the concept of combination as the order of the friends is not specific.

Comparison of fractions is easiest when they all have a common denominator, in this case we can make them all have a common denominator of 16...
12/16, 9/16, 3/16, 14/16, 6/16 so from least to greatest...
3/16, 3/8, 9/16, 3/4, 7/8
Answer:
A.
Step-by-step explanation:
We are given the two points (2,7) and (4,-1). In order to determine the linear equation, we need to find the slope and the y-intercept. First, find the slope <em>m.</em> Let (2,7) be x1 and y1, and let (4,-1) be x2 and y2:

Thus, the slope is -4.
Now, to find the y-intercept, we can use the point-slope form. Recall that the point slope form is:

Where (x1, y1) is a coordinate pair and m is the slope.
Use either of the two coordinate pair. I'm going to use (2,7). Substitute them for x1 and y1, respectively:

This is also slope-intercept form. The answer is A.
