because an oral presentation is a presentation that presents research and statistical information and a slide presentation could do the same but an oral presentation might show more statistical information and a slide might present more research, but if I had to choose one that might be the answer I would say Oral presentation since that's the most common way of presenting research of a topic
Answer:
(a) E(X) = 3
(b) Var(X) = 12.1067
Explanation:
(a) E[X]
E[X]T = E[X]T=A + E[X]T=B + E[X]T=C
= (2.6 + 3 + 3.4)/3
= 2.6 (1/3) + 3(1/3) + 3.4(1/3)
= 2.6/3 + 1 + 3.4/3
= 3
(b) Var (X) = E[X²]−(E[X])²
Recall that if Y ∼ Pois(λ), then E[Y 2] = λ+λ2. This implies that
E[X²] = [(2.6 + 2.6²) + (3 + 3²) + (3.4 + 3.4²)]/3
= (9.36 + 12 + 14.96)/3
= 36.32/3
= 12.1067
Var(X) = E[X²]−(E[X])²
= 12 - 3²
= 12.1067 - 9
= 3.1067
Answer:
Percent tax = 45%
Explanation:
Given:
Amount of tax charged = $1,152
Amount of purchase = $2,560
Find:
Percent tax
Computation:
Percent tax = [Amount of tax charged / Amount of purchase]100
Percent tax = [1152 / 2560]100
Percent tax = 45%
Answer
Hi,
In a developing nation, global factors that can influence the economy are political populism, global insecurity and the refugee crisis
Explanation
Making the explanation from 2016, this year was a challenging and difficult one for the global economy. First it was marked by political populism where President Donald Trump, Marine Le Pen and other influential figures took advantage weak economies and low productivity growth to talk on real wages and consumption.
The U.S presidential election being a major political event in 2016, the main issue was on the possibility of restoring the US as a global force for stability after Obama. Security issue raised due to inferior foreign policies and unwillingness to direct military forces in difficult regions.
Refugee was a major factor during 2016 where millions of individuals entered Europe seeking asylum. Many people were displaced in 2015 with countries like Germany, Hungary and Sweden receiving high inflows of refugee.
Good luck!
