<span>1.       </span><span>Give the word phrase of 12x
=> 12 is an integer
=> x in a variable or also called as unknown number
=> 12 = twelve
There the word phrase of this given number is
=> twelve times the number or twelve times x
 In giving the word phrase of a certain equation, simply give the word statement of each digits, variable and operations involve
Another example:
 => 5x + 1 – 2
=> five times the number added with one subtracted with two.</span>

120\frac{mile}{hour}\\\\&#10;1 \ mile=5280\ feet\\&#10;1\ hour=3600\ seconds\\\\&#10;120\frac{mile}{hour}=120*\frac{5280}{3600}=\frac{120*5280}{3600}=\frac{633600}{3600}=176\frac{feet}{second}\\\\&#10;\boxed{120\frac{mile}{hour}=176\frac{feet}{second}}

Let the probability of success on a Bernoulli trial be 0.26. a. In five Bernoulli trials, what is the probability that there wil
andreyandreev [35.5K]

Answer:

0.3898 = 38.98% probability that there will be 4 failures

Step-by-step explanation:

A sequence of Bernoulli trials forms the binomial probability distribution.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

Let the probability of success on a Bernoulli trial be 0.26.

This means that p = 0.26

a. In five Bernoulli trials, what is the probability that there will be 4 failures?

Five trials means that n = 5

4 failures, so 1 success, and we have to find P(X = 1).

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 1) = C_{5,1}.(0.26)^{1}.(0.74)^{4} = 0.3898

0.3898 = 38.98% probability that there will be 4 failures
