Explanation:

Here Given Sum to Infinity

$\sf S \infty \ =a_1 \ x \ \dfrac{1}{1-r}$

Identify following

a1 = 2

r = 1/2

Solve:

$\rightarrow \sf S \infty \ =2 \ x \ \dfrac{1}{1-\frac{1}{2} }$

$\rightarrow \sf S \infty \ =4$

The sum of this infinity series is 4

If you are presenting very complex and complicated information, it is best to:

Sometimes complex information all at once can be hard to gather... Simplifying ideas and concepts can help with the amount of cramming you're giving to your audience.

You're answer is B. Simplify ideas and concepts. :)

A Regional College uses the SAT to admit students to the school. The university notices that a lot of students apply even though

Aliun [14]

Answer:

0.191 is the probability that a group of 12 randomly selected applicants would have a mean SAT score that is greater than 525 but below the current admission standard of 584.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 500

Standard Deviation, σ = 100

n = 12

We are given that the distribution of SAT score is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(greater than 525 but 584)

Standard error due to sampling =

$\displaystyle\frac{\sigma}{\sqrt{n}} = \frac{100}{\sqrt{12}}$

$P(525 < x < 584) = P(\displaystyle\frac{525 - 500}{\frac{100}{\sqrt{12}}} < z < \displaystyle\frac{584-500}{\frac{100}{\sqrt{12}}}) = P(0.866 < z < 2.909)\\\\= P(z \leq 2.909) - P(z < 0.866)\\= 0.998 - 0.807 = 0.191 = 19.1\%$

$P(525 < x < 584) = 19.1\%$

0.191 is the probability that a group of 12 randomly selected applicants would have a mean SAT score that is greater than 525 but below the current admission standard of 584.
