The minimum score to join the genius society is 130.

What is the probability?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Given

A genius society requires an IQ that is in the top 2% of the population in order to join.

If an IQ test has a mean of 100 and a standard deviation of 15.

The top 2%, you have to have an IQ higher than 98% of the population (100% - 2%).

This is also known as the 98th percentile.

For this problem, you are given the probability and need to determine the raw score.

The closest probability is 0.97982 and that corresponds to a z-score of 2.05.

\rm z - score=\dfrac{x-mean}{standard \ deviatiion}\\\\2.05=\dfrac{x-100}{15}\\\\x-100=15\times 2.05\\\\x-100=30.75\\\\x=100+30.75\\\\x=130.75

Hence, the minimum score to join the genius society is 130.

EFGH is a parallelogram. Find the measure of FG and EG <br>​
navik [9.2K]

Answer:

FG = 44

EG = 80

Step-by-step explanation:

For FG:

1) 5z - 16 = 3z + 8

2) 5z = 3z + 24

3) 2z = 24

4) z = 12

5) 3(12) + 8 = 44

For EG:

1) 2w + 22 = 4w + 4

2) 2w = 4w - 18

3) -2w = -18

4) w = 9

5) 4(9) + 4 + 2w + 22 = 80

Identifying a constant of variation question<br><br> R= ?
jek_recluse [69]
Pressure and Volume are inversely related as:

P= \frac{R}{V}

We can also write it as:

PV=R

R is the constant of proportionality. Using the first row of given table, we can write:

2(4.155)=R \\  \\ &#10;R=8.31

Thus, the value of R, the universal gas constant is 8.31
