The SAT Reasoning Test (formerly called the Scholastic Aptitude Test) is perhaps the most widely used standardized test for coll

slamgirl [31]

Answer:

The score is $x = 1884$

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 1500$

The standard deviation is $\sigma = 300$

From the question we are told that the score follow a normal distribution

i.e $X \~ \ N( 1500 , 300)$

The proportion of score in the top 10% is mathematically

$P(X > x ) = P( \frac{X - \mu}{\sigma } > \frac{x - \mu}{\sigma } ) = 0.10$

Where x is the minimum score required to be in the top 10%

Now the $\frac{X - \mu}{\sigma } = Z (The \ Standardized \ value \ of \ X)$

So

$P(X > x ) = P( Z > \frac{x - \mu}{\sigma } ) = 0.10$

So

$P(X > x ) = P( Z > \frac{x - 1500}{300} ) = 0.10$

So the critical value of 0.10 from the normal distribution table is $Z_{0.10} = 1.28$

So

$\frac{x - 1500}{300} = 1.28$

$x = 1884$

Your friend incorrectly factors the expression 15x — 20xy as 5x(3— 4xy

nika2105 [10]

Answer:

no 15x — 20xy as 5x(3— 4xy is not correct

Step-by-step explanation:

15x — 20xy ≠ 5x(3— 4xy)

there are not equal because 5x(3 - 4xy) =

when you simplify the bracket, you will have

15x - 20x²y
