A binomial probability experiment is conducted with given parameters. Compute the probability of x successes in the n independen
Andrews [41]

Answer:

0.044

Step-by-step explanation:

n=9,p=0.9, x =6.

Apply Binomial probability we get

Sum P(x)=C(n,x) p^{x} (1-p)^{n-x} for x=6

Putting in the formula ,

we get

P(x) = C(9,6) 0.9^{6} 0.1^{3}

84 X 0.531441 X 0.001

= 0.044

Explain how the Quotient of Powers Property was used to simplify this expression.
Strike441 [17]

Answer:

\frac{5^{4}}{25} = 25

Step-by-step explanation:

I'm not sure if you had a typographical error with this statement, "5 to the fourth power, over 25 = 52."

According to the <u>Quotient Rule of Exponents</u><u>:</u>

\frac{a^{m}}{a^{n}} = a^{(m-n)}

Method 1:

In order for you apply the Quotient Rule, the base must be the same. Since 5 is a factor of 25, then you could rewrite 25 as 5². Doing so will give you the following exponential expression:

\frac{5^{4}}{5^{2}} = 5^{(4 - 2)} = 5^{2} = 25

Method 2:

Even if you solve the given problem manually, you'd still get the same answer:

\frac{5^{4}}{25} = \frac{5*5*5*5}{25} = \frac{625}{25} = 25

Both methods produced the same result, proving that the correct answer is 25.

In a random sample of 55 newborn babies, what is the probability that 44% or fewer of the sample are boys. (use 3 decimal places
wel
<span>0.053 The standard deviation of a binomial variable is sqrt(n*P*(1-P)) where n is the sample size and P is the probability of one of the outcomes. The sample size is 55 and we'll assume that both male and female are equally likely outcomes. standard deviation = sqrt(55*.5*.5) = 3.7081% 44% is 1.6181 standard deviations away from the mean of 50%. Looking this up on a standard deviation chart gives .0526 probability which we'll round to 0.053</span>
