A production manager for Telektronics claims that her new process for manufacturing CDs is better because the rate of defects is lower than 2% which had been the rate of defects in the past. To support her claim, she manufactured a batch of 5000 CDs then randomly selects 15 of them for testing, with the result that there are no defects among the 15 selected CDs. Assuming that the new method has the same 2% defect rate as in the past, find the probability of getting no defects among the 15 CDs.

answer: was that a question or answer?

step-by-step explanation:

the reporter's right

step-by-step explanation:

1/4 = .25 / 25%

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.

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.
