Answer:
Mean (Average): 21.44444
Median (Middle): 22
Mode (Most Common): 29
Step-by-step explanation:
Answers:
1) A
2) -3
Work:
1) The answer is A because there is a common difference of 2.5 between each term, meaning that exactly 2.5 is added between each successive term of the sequence.
2) The answer is -3 because in order to get from one term to the next in the above sequence, you must subtract 3. For instance, 11-3=8, 8-3=5, and so on. Since you are subtracting the value must be negative, giving you -3.

Step-by-step explanation:
Answer:
(, ) = (30, 16)
Step-by-step explanation:
First find the similarity
Since you know the legnth of the hypotenuse (the longest one) for both traingles, you can find the similarity by dividing the longer by the shorter:
50 ÷ 20 = 2.5
The similarity between the 2 triangles is 2.5.
Now find the length of on the longer one, use the shorter one's length and the similarity:
12 × 2.5 = 30
So the length of is equal to 30
Now lets find , lets use the length of the larger triangle this time and divide the length of the longer leg (there are 2 legs in every triangle, if you don't know the hypotenus's length, use the pythagorean theorem) and divide it by the similarity:
40 ÷ 2.5 = 16
= 16
WooHoo! (, ) = (30, 16)
