Answer:
12 square units
Step-by-step explanation:
A = 1/2·h(sum of bases)
A = 1/2(4)(2+4)
A = 2(6) which is 12 square units
What is the median of the data set? {23, 19, 20, 17, 22, 15, 25, 18, 17, 18, 24, 21}

First put the numbers in order, least to greatest.
15, 17, 17, 18, 18, 19, 20, 21, 22, 23, 24, 25
Count the amount of number in the data set. In this one there is 12. Since 12 is an even number, the media will not be in the data set because there is no possible way to have the same amount of numbers on each side. SO, count 6 numbers in to the data set (which would be 19). Next to that is 20. Add 19+20=39. Divide 39 by 2 (2 numbers), which is 19.5
The median of this data set is 19.5
Hope I helped :)
We know by definition that complementary angles add up to 90 degrees. We can set up an equation using the ration given:
17x+13x=90, with x representing the amount you need to multiply the ratio by to get 90.
17x+13x=90
30x=90
x=3
We now know that the number we multiply the ratio by is 3. The smaller number in the ratio is 13, and so therefore we multiply it by 3.
3*13=39
The answer is 39 degrees.
X = -4. Hope this helps ;)
