Y=7
It's a horizontal line at height 7
The rate of interest is 25%
<u>Explanation:</u>
Given:
Principal, P = $2,000
Amount, A = $2500
Time, t = 1 year
Rate of Interest, r = ?
We know:

On substituting the value we get:


Therefore, the rate of interest is 25%
8. Adjacent and complementary angles are #1 & 2, since they are next to each other and added together equal 90°
9. Vertical angles are # 1 & 4, since they are opposite to each other.
10. Adjacent and supplementary angles are #4&5, since they are next to each other and add up to 180°
11. The acute angles are #1&2&4, since they are all less than 90°
12. The obtuse angles are #5&6, since they are greater than 90°
13. The angle measurements are:
1: 42°
2: 90-#1 = 90-42 = 48°
3: right angle = 90°
4: opposite #1 = 42°
5: 180-#4 = 180-42 = 138°
6. opposite #5 = 138°
btw, we cannot see the diagram for #5,6,7
Answer:
range
Step-by-step explanation:
difference between the highest and lowest points in a data set = range
The mean is the average of all the points
The median is the middle of all the points
The mode is the point the appears the most often
Answer:
15 pairwise comparisons; 30 pairwise rankings.
Step-by-step explanation:
Each of the 6 candidates can be ranked #1 in relation to the other 5, for a total of 30 pairwise rankings.
Of course, two of those are comparisons of the same pair of candidates. The same is true of all pairs of candiates, so the number of pairwise comparisons is half the possible number of rankings: 30/2 = 15.
_____
For example, for the pair of candidates A and B, you can have the two rankings ...
These cases are possible outcomes of the the one pairwise comparison ...
