Answer:

That is, they are equivalent expressions. Two expressions are said to be equivalent if they have the same value irrespective of the value of the variable(s) in them. Example 1: Are the two expressions 2y+5y−5+8 and 7y+3 equivalent?

Firlakuza [10]

Answer:

$P(X=0)=(24C0)(0.04)^0 (1-0.04)^{24-0}=0.375413$

$P(X=1)=(24C1)(0.04)^1 (1-0.04)^{24-1}=0.$

So then the probability that the batch would be accepeted is:

$0.375413+0.375413=0.7508$

Step-by-step explanation:

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=24, p=0.04)$

On this case p=0.04 represent the probability that a random the tablet would be NOT accepted

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

They accept the batch if there is only one or no tablet that doesn’t meet the test specification, so let's find the individual probabilities for this case:

$P(X=0)=(24C0)(0.04)^0 (1-0.04)^{24-0}=0.375413$

$P(X=1)=(24C1)(0.04)^1 (1-0.04)^{24-1}=0.$

So then the probability that the batch would be accepeted is:

$0.375413+0.375413=0.7508$

Write the measure 29° 6' 6" as decimal to the nearest thousandth.

den301095 [7]

This angle is "29 degrees 6 minutes 6 seconds".

-- There are 60 minutes in 1 degree.
   So 1 minute = 1/60 degree.

-- There are 60 seconds in 1 minute.
      So 1 second = 1/60 minute = 1/3600 degree.

29 6' 6" = (29)° + (6/60)° + (6/3600)°

   = (29)° + (0.1)° + (0.001666...)°

   = 29.101666...°

Rounded to the nearest thousandth of a degree: 29.102°
