This probability distribution shows thetypical grade distribution for a Geometrycourse with 35 students. GradeАBCDFFrequency 5101532Using the frequencies given, find theprobability that a student earns a grade of A. p=[?]Enter a decimal rounded to the nearest hundredth. Enter

The probability that a student earns a grade of A is 14.29% or 0.14

STEP-BY-STEP EXPLANATION:

The probability would be the quotient of the number of frequency of Grade A and the total number of students:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
