Answer:

Tom will be admitted to the university.

Explanation:

To find out if Tom will be admitted to the university, we must calculate whether he was better than 70% of the students who took the test. For this we will do the following calculation:

Z = (x − μ) / σ

μ = 500

σ = 100

x = 585

Z = (585−500) /100=0.85

Now we must find the probability:

P (Z <0.85) = P (Z <0) + P (0 <Z <0.85)

P (Z <0) = 0.5

P (0 <Z <0.85) = 0.3023

(from Z-table) ---> = 0.5 + 0.3023 = 0.8023.

This means that Tom was better than 80.23% of the students who took the exam, so he will be admitted to the university.

Answer:yes he will be admitted.

Explanation:

Standard deviation is a measure of the amount of variation of data.

Here, we have a low standard deviation of 100 as compare with the mean value of 500. Low standard deviation indicates that the values are close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.

It means that most candidates scores are centred around 500 mark. Tom had 585, which is greater than 500 mark and 85 mark higher than the mean value.

Therefore he has chances of getting admission.

How can globalization cause a pandemic? explain in 3 to 4 sentences
Anton [14]

Answer:

The pandemic has caused the largest and fastest decline in international flows — including trade, foreign direct investment, and international travel — in modern history. While these numbers imply a major rollback of globalization’s recent gains, they don’t necessarily signal a fundamental collapse of international market integration. But how deep will the plunge really be? How fast can we expect global flows to rebound? And how might future flow patterns look different from the past? Leaders can find clues about the future and actionable implications for their companies by focusing on five key drivers of globalization’s trajectory: 1) global growth patterns; 2) supply-chain policies; 3) superpower frictions and fragility; 4) ongoing technical shifts; and 5) my opinion
