Please help geometry questions<br> find X

ladessa [460]

Answer:

Step-by-step explanation:

The line x originates from the center of the circle and forms a perpendicular line with line RS, which means that the line is bisected.

That means that line RT is half of line RS, or 7.

Then we can use the Pythagorean Theorem to find the measure of x.

$7^2+b^2=9^2$

$49+b^2=81$

$b^2=32$

b = √32

b ≈ 5.66

vovangra [49]

Answer:

456

Step-by-step explanation:

Let X be the SATscore scored by the students

Given that X is normal (1000,200)

By converting into standard normal variate we can say that

$z=\frac{x-1000}{200}$ is N(0,1)

To find the top 10% we consider the 90th percentile for z score

Z 90th percentile = 1.28

$X= 200+1.28(200)\\= 200+256\\=456$

i.e. only students who scored 456 or above only should be considered.
