In a certain class of students, there are 10 boys from wilmette, 4 girls from kenilworth, 6 girls from wilmette, 7 boys from glencoe, 3 boys from kenilworth and 9 girls from glencoe. if the teacher calls upon a student to answer a question, what is the probability that the student will be from kenilworth? round your answer to three decimal places.

answer: slight chance that it will happen

step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
