The mean absolute deviation of the data set is 4
a is the best way to find it if there is points involved so keep that in mind
$430 because you divide 15,480 divided by 36 and get your answer
Answer:
A = 40°
B = 50°
Step-by-step explanation:
If cos A = sin B, then A + B = 90
So, 2x/3 + 20 + 2x - 10 = 90
2x + 60 + 6x - 30 = 270
8x + 30 = 270
8x = 240
x = 30
2x/3 + 20 = 60/3 + 20 = 20 + 20 = 40
2x - 10 = 2(30) - 10 = 60 - 10 = 50 or 90 - 40 = 50
Answer:
That is a lot of questions to answer. But I will try.
5)
a) 6 square units
b) 5/6
Second picture
1. Area = 6
2. Area = 4.5
3. Area = 20
4. Area = 9
5. Area = 17.5
Third picture
a) 8 units because if you move the bottom triangle to the top of the other triangle it makes a rectangle with height of 2 and length of 4.
I'm sorry I have to go I would love to finish this but I hope what I gave helps you!
