Students who attend Anytown College pay either in-state or out-of-state tuition, depending on where they reside. The amount, I,

spent on in-state tuition and the amount, O, spent on out-of-state tuition for a randomly selected student both follow a Normal distribution.
The mean and standard deviation of the sum S = I + O of tuition for a randomly selected pair of in-state and out-of-state students are μS = $6,348.75 and σS = $1,508.48.

Use the z-table to answer the question.

What is the probability that the sum of a randomly selected pair of in- and out-of-state students has a tuition charge of more than $8,000?

3. A quadratic polynomial whose<br>product and the sum of<br>zéroes are -12 and 1​
muminat

Answer:

the equation is : x²-x-12

Step-by-step explanation:

the quadratic equation is in the form of : y=ax²+bx+c

the product of the zeros is -12 and the sum is 1

b  = - 1

c=-12 (product)

y=x²-x-12

check : factorize first (x+3)(x-4)=0

either x+3=0 then x=-3

or x-4=0 then x=4

-3*4=-12

-3+4=1

the equation is : x²-x-12
