Answer:
d
Step-by-step explanation:
csc²θ-cot²θ=1
csc²θ-(4/3)²=1
csc²θ=1+16/9=25/9
cscθ=√(25/9)=5/3
The inside angles of the triangle add to equal 180 and so does m/FEG with unknown triangle angle.
x+2x = x+40
2x = 40
x = 20
mFEG
= 20 + 40
= 60

Answer:
The distribution is <u>positively skewed</u>.
Step-by-step explanation:
It's not symmetric because the distribution in the chart isn't equally shown or marked. It's not negative skewed either because for it to be negative the graph would have to go down in a negative direction, usually the left, but in the picture you posted the graph is going down in the right direction. Lastly, positively skewed graphs or charts look like the one you posted. They go down in the right direction, hence why they're called "positively" skewed. The right tail of the distribution is longer in positively skewed graphs or charts.
