A certain large manufacturing facility produces 20,000 parts each week. The manager of the facility estimates that about 1% of t
Slav-nsk [51]

Answer:

198 is the variance for the number of defective parts made each week.      

Step-by-step explanation:

We are given the following in the question:

Number of parts produced each week =  20,000

Percentage of defective parts = 1%

We have to calculate the variance for the number of defective parts made each week.

We treat defective part as a success.

P(Defective part) = 1% = 0.01

p = 0.01

Then the number defective parts follows a binomial distribution .

Formula for variance =

\sigma^2 = np(1-p) = 20000(0.01)(1-0.01) = 198

Thus, 198 is the variance for the number of defective parts made each week.

Below is a proof showing that the sum of a rational number and an irrational number is an irrational number.
ankoles [38]

Answer:

Step-by-step explanation:

To prove: The sum of a rational number and an irrational number is an irrational number.

Proof: Assume that a + b = x and that x is rational.

Then b = x – a = x + (–a).

Now, x + (–a) is rational because addition of  two rational numbers is rational (Additivity property).

However, it was stated that b is an irrational number. This is a contradiction.

Therefore, the assumption that x is rational in the equation a + b = x must be incorrect, and x should be an irrational number.

Hence,  the sum of a rational number and an irrational number is irrational.

How many 7 digit phone numbers are there assuming the first digit can't be a 0 or a 1?
Anettt [7]
The first digit can be any one of the numbers 2-9 That a total of 8 numbers.

The next 6 digits can be any permutation of 6  from the numbers  0 to 9.
(10 numbers)

nPr  =  n! / r!

so here we have  10P6  = 10! / 6!  =  10*9*8*7  =  5040

So final answer  is 8 * 5040 = 40,320
