Answer:
Since the formula is (1/2) base height, (1/2) of 10 is 5 so multiply 5 times the base polynomial resulting in 20x^2y + 10xy^2 ft^2. So, if you multiply the length times width then divide by 2 you get the same answer. Sorry if this is incorrect.
Hope this helps, have a great day and stay safe!
Answer:
(10,6)
Step-by-step explanation:
The equation you would use to solve this is (x1+x2/2 , y1+y2/2) so when you plug in the numbers you get this (6+14/2 , 3+9/2) which eventually simplifies into (10, 6)
1. interquartile range
2. all
Solution :
<u>Sample size</u> <u> Sample mean</u> <u> Sample S.D.</u>
Sample 1 
Sample 2 
= 60
Therefore, significance level, α = 0.1
Critical value, t* = 1.6706
So, the margin of error, 
= 559.9896
Lower limit, 
Upper limit, 
Therefore 90% C.I. is (44402.0104, 55597.9896) or 
3x + (2x - 25) = 180
5x - 25 = 180
5x - 25 + 25 = 180 + 25
5x = 205
5x / 5 = 205 / 5
X = 41
Hope that is right, sorry if it’s not
Supplementary means it equals 180 degrees
