The letters a, b, c, d, e, and f are written on six different ping pong balls and put into a bag. the letters h, i, j, and k are written on another four different ping pong balls and put into a second bag. then the letters o, p, q, r, s, t, and u are written on another seven different ping pong balls and put into a third bag. if one ping pong ball is randomly selected from each of the three bags, what is the probability that at least one vowel (a, e, i, o, u) is selected?

the correct answer is $7.38

step-by-step explanation:

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.

i can answer this if i have the answer choices
