Butch has a collection of 40 vinyl records from throughout the 20th century including nine from the 40s two from the 50s three from the 60s four from the 70s, and oight
from the bos if he randomly selects one from his collection of 40, find the probability it will be from each of the following decades
the probability that it is from the 40$ ls
(type an integer or a simplified fraction)
the probability that it is from the 50s is
(type an integer or a simplified fraction)

answer: dead jah

step-by-step explanation:

bullet + jah= dead jah

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

segment bisector

step-by-step explanation:

line segment bisector. definition: a line, ray or segment which cuts another line segment into two equal parts. try this drag one of the orange dots at a or b and note the the line ab always divides the line pq into two equal parts.
