We know that
<span>The measure of the external angle is the semi-difference of the arcs that it covers.
</span>so
m∠BCD=(1/2)*[arc AE-arc BD]
20=(1/2)*[85-BD]
40=85-BD
BD=85-40
BD=45°
the answer is
BD=45°
No. The new area is 2.25 times the original area. That's (1.5 times 1.5).
Zero pair is a pair of numbers whose sum is zero, used to illustrate addition and subtraction problems... with positive and negative integers.
e.g. +1 -1
I hope that this helps

Answer:
D. H0: p ≤0.36 H1: p>0.36


D. Reject H0. There is sufficient evidence to support the hypothesis that the proportion of admissions officers who visit an applying students' social networking page has increased in the past year
Step-by-step explanation:
To solve this problem, we run a hypothesis test about the population proportion.

The appropriate hypothesis system for this situation is:


Since, the calculated statistic
is greater than critical
, the null hypothesis should be rejected. There is enough statistical evidence to state that the proportion of admissions officers who visit an applying students' social networking page has increased in the past year.
