According to a recent survey, 31 percent of the residents of a certain state who are age 25 years or older have a bachelor’s degree. A random sample of 50 residents of the state, age 25 years or older, will be selected. Let the random variable B represent the number in the sample who have a bachelor’s degree. What is the probability that B will equal 40 ?
Answer:
The probability of getting B=40 is [tex]0.11\times 10^{-11}[/tex] which is negligible.
Step-by-step explanation:
Given that 31 percent of the residents of a certain state who are age 25 years or older have a bachelor’s degree.
Assuming the population of the state aged 25 years or more is Bernoulli's population.
So, when 1 person aged 25 years or more from the state selected randomly, the probability of that person, p, having a bachelor’s degree,
[tex]p= 31/100=0.31\cdots(i)[/tex]
Now, according to Bernoulli's formula, the probability of exactly r success from the total number of sample n is
[tex]P(r)=\binom{n} {r}p^r(1-p)^{n-r}\cdots(ii)[/tex]
where p is the probability of success.
Here, a random sample of 50 residents of the state, age 25 years or older, will be selected.
So, n=50.
Given that variable B represents the number in the sample who have a bachelor’s degree,
We have to find the probability that B will equal 40.
So, r=B= 40.
Now, putting these values in equation(ii) and using p=0.25 from equation (i), we have
[tex]P(r=40)=\binom{50} {40}(0.31)^{40}(1-0.31)^{50-40}[/tex]
[tex]=\frac {50!}{40! (50-40)!}(0.31)^{40}(0.69)^{10} \\\\=\frac {50!}{40! \times 10!}(0.31)^{40}(0.69)^{10} \\\\=0.11\times 10^{-11}[/tex]
So, the probability of getting B=40 is [tex]0.11\times 10^{-11}[/tex] which is negligible.
Using the binomial distribution, it is found that there is a [tex]1.13 \times 10^{-12}[/tex] probability that B will equal 40.
-----------------------------
For each resident, there are only two possible outcomes. Either they have a bachelor's degree, or they do not. The probability of a resident having a bachelor degree is independent of any other resident, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
p is the probability of a success on a single trial.
In this problem:
31% have a bachelor's degree, thus [tex]p = 0.31[/tex].Sample of 50, thus [tex]n = 50[/tex].The probability is:
[tex]P(B = 40) = C_{50,40}(0.31)^{40}(0.69)^{10} = 1.13 \times 10^{-12}[/tex]
[tex]1.13 \times 10^{-12}[/tex] probability that B will equal 40.

Answer:
A) Ms. Hynnes'
B) Mr. Charles'
Step-by-step explanation:
I start by finding the LCM (lowest common multiple) of 5, 9, and 7, which is 315. Then, to calculate the top number, I divide 315 by the denominator to determine how many times I need to multiply the numerator. For 5, it's 63, giving us a numerator of 126. For 9, it's 35, giving us a numerator of 140. For 7, it's 45, giving us a numerator of 135. I then compare the numbers to find the answer.

Compré mi despensa en línea (usando la página de un centro comercial) y en total por los productos que adquirí debía pagar $1600, pero me hicieron un cargo extra por envío así que al final me cobraron $1620. ¿Cuál es el porcentaje, de mi compra, que me cobraron por gastos de envío?
Answer:
1.235%
Step-by-step explanation:
Paso 1
Calculamos el costo de envío
= $ 1620 - $ 1600
= $ 20
Paso 2
¿Cuál es el porcentaje de mi compra que me cobraron por los gastos de envío?
Esto se calcula como:
(Costo de envío / Cargos totales) × 100
= 20/1620 × 100
= 1.2345679012%
= Aproximadamente = 1.235%

Step-by-step explanation:
in 2011, a professional climber scaled the outside of the Burj Khalifa, making it all the way up to 828 meters ( the highest point on which a person can stand) in 6 hours answers.
1. How far did they climb in the first 2 hours?
2. How far did they climb in 5 hours
3. How far did they climb in the final 15 minutes?
Answer:
Step-by-step explanation:
Given that:
A professional climber makes his way up to 828 meters in 6 hours in Burj Khalifa.
Therefore; in two hours, he would have climbed:
x = (828 m × 2hrs)/6 hrs
x = 276 miles
In five hours, he would have climbed;
y = ( 828 m × 5 hrs)/6 hrs
y = 690 miles
SInce 60 minutes = 1 hour
Then 15 minutes will be ( 15)/60 = 0.25 hours
Thus, in the last 15 minutes;
He climbed = (828 m × 0.25 hrs)/6 hrs = 34.5 miles
