Hello,
since sin 30°=1/2 and cos 30°=√3/2
then
8(cos 30+i sin 30°)=8*(√3/2+i/2)=4√3+4i
Okay..it goes -75, 0, 25, and then 50.
Hope this helps.
Answer:
22 square units
Step-by-step explanation:
Area of a triangle formula:
A = 0.5bh
Given:
b = 11
h = 4
Work:
A = 0.5bh
A = 0.5(11)(4)
A = 5.5(4)
A = 22
I believe that the answer is about 11 square feet because when you divide 16 by 1.5, you get 10.666666667, and most likely they won't be accepting an answer like that. So, you round to the nearest square feet and you get 11.
Answer:
Yes, there is one outlier (lower)
Step-by-step explanation:
Looking at the distribution of the lower/smallest observation, we can see that there is a values in the lower/smallest that is very far from others. See the attached box-plot for understanding.
The median is the line in the middle of the box-plot.
The Lower fourth is the lower whisker line and upper fourth is the upper whisker line. The lower box (just below the median) line is the 1st quartile and the upper box line (just above the median) is 3rd quartile.
