Answer:
99.8% probability of at least one failure.
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Probability of success is 30%.
This means that [tex]p = 0.3[/tex]
Five trials:
This means that [tex]n = 5[/tex]
Find the probability of at least one failure in five trials of a binomial experiment in which the probability of success is 30%.
Less than five sucesses, which is:
[tex]P(X < 5) = 1 - P(X = 5)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 5) = C_{5,5}.(0.3)^{5}.(0.7)^{0} = 0.002[/tex]
[tex]P(X < 5) = 1 - P(X = 5) = 1 - 0.002 = 0.998[/tex]
0.998*100% = 99.8%
99.8% probability of at least one failure.

Answer:
60% decrease
Step-by-step explanation:
Subtract to find how much money it went down by
95 - 38= 57
then use proportions
x/100 = 57/95
then cross multiply
5700 = 95x

Convert vertex form f(x)=(x+2)^2-25 to factored form.
Answer:
f(x)=x^2+4x-21
Step-by-step explanation:
Answer:
f(x) = (x + 7) (x - 3)
Step-by-step explanation:
f(x)=(x+[tex]2)^{2}[/tex]-25
(x + 7) (x - 3) we put the 2 x's because of the (x+2)^2
now the + 7 and - 3, multiply the 2 numbers = -21 then use those 2 in
(x+2)^2 to add for the answer = -25
Solve for the measure of x.

What is the difference between simplifying radicals and estimating its value?
Answer:
Simplifying radicals is the process of manipulating a radical expression into a simpler or alternate form. Generally speaking, it is the process of simplifying expressions applied to radicals.
Estimation (or estimating) is the process of finding an estimate, or approximation, which is a value that is usable for some purpose even if input data may be incomplete, uncertain, or unstable. The value is nonetheless usable because it is derived from the best information available.
Step-by-step explanation:
The radical symbol represents the root of a number and is read as x radical n or the nth root of x.
What is a radical?The symbol " that expresses a number's root is known as radical, and it is read as x radical n or the nth root of x. The horizontal line that surrounds the number is known as the vinculum, and the number beneath it is known as the radicand. The index or degree is the number n written before the radical.
The process of transforming a radical expression into a simpler or alternate form is known as simplifying radicals. In general, it is the process of simplifying expressions that are applied to radicals.
Estimation (or estimating) is the process of determining an estimate, or approximation, which is a value that can be used for a specific purpose despite the fact that the input data may be incomplete, uncertain, or unstable. The value is still useful because it is based on the best available information.

[tex]27 \times 13[/tex]
Answer:
your answer is 351: )
Step-by-step explanation:
Have a great day ty!
To explain what 27 times 13 means, look at it as 27 added together 13 times. To get the answer, you could just write down the number 27, 13 times and then add the 27 numbers together.
If you have one of those old-fashioned handheld calculators, you can double check that the answer is 351 by pressing 27, then x, then 13, and then = to get the answer.
Answer:
[tex]351[/tex]
Step-by-step explanation:
[tex]27\times \:13[/tex]
Step 1: Line up the numbers; Multiply the top number by the bottom number one digit at a time starting with the ones digit (from right to left)
[tex]\begin{matrix}\space\space&2&7\\ \times \:&1&3\end{matrix}[/tex]
Step 2: Multiply the top number by the bolded digit of the bottom number
[tex]\begin{matrix}\space\space&\textbf{2}&\textbf{7}\\ \times \:&1&\textbf{3}\end{matrix}[/tex]
Step 3: Multiply the bold numbers; Carry 2 to the column on the left and write 1 in the result line
[tex]7\times \:3=21\\\\\frac{\begin{matrix}\space\space&2&\space\space\\ \space\space&2&\textbf{7}\\ \times \:&1&\textbf{3}\end{matrix}}{\begin{matrix}\space\space&\space\space&1\end{matrix}}[/tex]
Step 4: Add the carried number to the multiplication
[tex]2+2\times \:3=8\\\\\frac{\begin{matrix}\space\space&\textbf{2}&\space\space\\ \space\space&\textbf{2}&7\\ \times \:&1&\textbf{3}\end{matrix}}{\begin{matrix}\space\space&8&1\end{matrix}}[/tex]
Step 5: Multiply the top number by the bolded digit of the bottom number
[tex]\frac{\begin{matrix}\space\space&\textbf{2}&\textbf{7}\\ \times \:&\textbf{1}&3\end{matrix}}{\begin{matrix}\space\space&8&1\end{matrix}}[/tex]
Step 6: Multiply the bold numbers
[tex]7\times \:1=7\\\\\frac{\begin{matrix}\space\space&\space\space&2&\textbf{7}\\ \space\space&\times \:&\textbf{1}&3\end{matrix}}{\begin{matrix}\space\space&\space\space&8&1\\ \space\space&\space\space&7&\space\space\end{matrix}}[/tex]
Step 7: Multiply the bold numbers
[tex]2\times \:1=2\\\\\frac{\begin{matrix}\space\space&\space\space&\textbf{2}&7\\ \space\space&\times \:&\textbf{1}&3\end{matrix}}{\begin{matrix}\space\space&\space\space&8&1\\ \space\space&2&7&\space\space\end{matrix}}[/tex]
Step 8: Add the rows. Add zero for simplicity
[tex]\frac{\begin{matrix}\space\space&\space\space&2&7\\ \space\space&\times \:&1&3\end{matrix}}{\begin{matrix}\space\space&0&8&1\\ \space\space&2&7&0\end{matrix}}[/tex]
[tex]81 + 270 = 351[/tex]
Therefore 27 times 3 is 351

Explain the effect level of significance and sample size have on hypothesis testing results. Provide an example and explain how they might impact business decisions. In replies to peers, discuss whether you agree or disagree with the example provided and justify your response.
Solution :
The level of significance refers to the probability of the null hypothesis that may be rejected in the study by the observer. As the sample size increases, the p value also increases but the significance remains same. When the sample size increase and becomes large, the null hypothesis can be rejected more easily.
The business decisions are taken defending the significance level of the statistical validation in cases of uncertainty. Suppose the null hypothesis is the sales after the marketing campaigning remains same. The company will launch the marketing campaign when the confidence level is 95% so that after the campaign the sales will increase. It means that the significance level must be high enough for rejecting null hypothesis of sales post of the marketing campaign that remains same.
When the sample size increases, the sensitivity of hypothesis increases, and for a large sample, the hypothesis may be rejected even though it is true.

Michelle and Pierre both want to buy guitars, Michelle has already saved $60, and
plans to save $5 per week until she can buy the guitar, Pierre has $25, and plans to save
$12 per week. How many weeks will pass before Michelle and Pierre have the same
amount of money?
Answer:
on the 5th week they would both have the same amount of money they would both have a total of 85$
Step-by-step explanation:
The number of weeks will pass before Michelle and Pierre have the same amount of money will be 5.
What is the solution of the equation?The solution of the equation means the value of the unknown or variable.
Let x be the number of the weeks and y be the total amount.
Michelle and Pierre both want to buy guitars, Michelle has already saved $60, and plans to save $5 per week until she can buy the guitar, Pierre has $25, and plans to save $12 per week.
Then the equations will be
y = 5x + 60 ....1
y = 12x + 25 ....2
Subtract equation 1 from equation 2. Then we have
7x – 35 = 0
7x = 35
x = 5 weeks
Then the number of weeks will pass before Michelle and Pierre have the same amount of money will be 5.
