Theres only 3 shapes that can form such regualr tessellations triangle square and regular hexagon so that being said triangle is your answer
If the angle is over 120 its obtuse is it if below 40 its acute
Umm so it’s not coming out as a polynomial but these answers came out
type of problem. Try the examples below.
Answer:
a.

b-Check illustration below
c.(-0.0517,0.0177
Step-by-step explanation:
a.let
denote processes 1 & 2.
For
: T1=10,n1=200
For
:T2=20,n2=300
Therefore

b. To test for hypothesis:-
i.

ii.For a two sample Proportion test

iii. for
(0.5 alpha IS 0.025),
reject
if
iv. Do not reject
. The noncomforting proportions are not significantly different as calculated below:

z=-0.78
c.
for the p1-p2 is given as:

=(-0.0517,+0.0177)
*CI contains o, which implies that proportions are NOT significantly different.
