Answer:
i think its 12
Step-by-step explanation:
Answer:
Short leg = 10
Longer leg = 10
Hypotenuse = 20
Step-by-step explanation:
The given is a special right triangle, its angle measures are as follows:
30-60-90 and the side lengths will follow as:
x, x, 2x respectively.
The length of hypotenuse (sees angle measure 90) is represented with 2x and it's given as 20
We can conclude x = 10 from this
So the length of short leg is 10
Then the length of longer leg is 10
The length of hypotenuse is already given as 20
Calculate the mean, median, and mode of the following set of data. round to the nearest tenth. 11, 9, 7, 6, 8, 2, 15, 1, 12, 15,

Median is the middle most number, so you order from least to greatest. :)
<span>11, 9, 7, 6, 8, 2, 15, 1, 12, 15, 14 which becomes: 1, 2, 6, 7, 8, 9, 11,12, 14,15,15.. So 1,2,6, 7, 8 can be grouped into the first upper section. 9 is the median since it's the middle because 11,12,14,15,15.
Mean is adding all values up and dividing by the total number you have. So you kind of did that, soo 100/11 = 9.1.
The mode is what is repeated the most, so, 15 appears the most (twice in total I believe). You already had the answers, but I hope this was enlightening ^^</span>
Area of triangle(a) =1/2(b)(h)
a= 1/2((3y-2)(y-1)
a=1/2(3y^2 -3y-2y+2)
therefore the area equals
a=3/2y^2-5/2y+1
solve the second by the same means
