Given that a directional hypothesis is a prediction made by a researcher regarding a positive or negative change, relationship, or difference between two variables of a population, a two-tailed test is the perfect tool to validate it because a two-tailed test is designed to examine both sides of a specified data range.
So the final answer to this question is:
True.
If you use a mixture of formats in a single document, it can be confusing to the reader. This is the exact opposite of what formatting is supposed to do.
Answer: c. Each line of the document has different formatting applied to it.
You need to upload pictures of the sources so we can see them :)

find the area under the curve first
![\int\limits^{\sqrt[3]{\pi}}_0 {x sin(x^3)} \, dx =0.61157809233184](https://tex.z-dn.net/?f=%20%5Cint%5Climits%5E%7B%5Csqrt%5B3%5D%7B%5Cpi%7D%7D_0%20%7Bx%20sin%28x%5E3%29%7D%20%5C%2C%20dx%20%3D0.61157809233184)
then solve c∛π=0.61157809233184
c≈0.41757577488026
round if necicary

alright, solve where they itnersect
x²=y=mx
x²=mx
x²-mx=0
x(x-m)=0
set to zero
x=0
x-m=0
x=m
they intersect at x=0 and x=m
which one is on top?
hmm
y=mx will always be on top (I don't know how to prove that but it's on top)
so we do

solve

so

m³=48
m=2∛6
