The combined math and verbal scores for students taking a national standardized examination for college admission, is normally d
kipiarov [429]

Answer:

The minimum score that such a student can obtain and still qualify for admission at the college = 660.1

Step-by-step explanation:

This is a normal distribution problem, for the combined math and verbal scores for students taking a national standardized examination for college admission, the

Mean = μ = 560

Standard deviation = σ = 260

A college requires a student to be in the top 35 % of students taking this test, what is the minimum score that such a student can obtain and still qualify for admission at the college?

Let the minimum score that such a student can obtain and still qualify for admission at the college be x' and its z-score be z'.

P(x > x') = P(z > z') = 35% = 0.35

P(z > z') = 1 - P(z ≤ z') = 0.35

P(z ≤ z') = 1 - 0.35 = 0.65

Using the normal distribution table,

z' = 0.385

we then convert this z-score back to a combined math and verbal scores.

The z-score for any value is the value minus the mean then divided by the standard deviation.

z' = (x' - μ)/σ

0.385 = (x' - 560)/260

x' = (0.385×260) + 560 = 660.1

Hope this Helps!!!

What are the solutions to the system of equations <br> {-x+y=4<br> {y+12=x^2+x
Gnoma [55]

Answer:

Step-by-step explanation:

y=4+x          ............................................ (1)

y=x^2+x-12  ............................................ (2)

now equate both (1) and (2)

4+x=x^2+x-12

=>x^2=16

x=-4,4

now substitute the values of x ,

when x=-4 , y becomes 0

when x=4  , y becomes 8

so, solution set:

(-4,0) and (4,8)
