Answer:
Circumference would be 25.12ft
Step-by-step explanation:
So circumference formula is pi(diameter)
We know the radius so to find the diameter we multiply the radius by 2.
so 4(2)=8
and since pi is 3.14 then multiply 8(3.14)
youll get 25.12
Answer:25.12
Step-by-step explanation:
formula is d(pi)
so 8(3.14)
25.12
How do you do this problem and what are the conditions met that makes this a binomial distribution(all 3 conditions)?
The three conditions of a binomial distribution are:
Each trial has two outcomes (eg: "yes or no", "true or false", "red chip or not red chip", etc)There are a fixed number of trials. This is the value of n.Each trial has the same probability of success. This is the value of p.In this case, all of the conditions of a binomial have been met because...
There are two outcomes. We either get a red chip, or we don't get a red chip. I'm focusing on the red chips because the question asks about the probability of getting 1 red chip.We have n = 5 trials, where each trial consists of selecting a chip and putting it back. It's important to put the chip back so that p is not altered.The probability of success is p = 6/9 = 2/3 This is the probability of selecting a red chip. This is because there are 6 red out of 6+3 = 9 total.Since we only want one red chip, and there are 5 slots to fill (1 red+4 black), this must mean there are exactly 5 ways to get what we want.
We could have the following selections
RBBBBBRBBBBBRBBBBBRBBBBBRWith R = red and B = black. This value 5 will be used as the binomial coefficient. You can find this value through the use of the nCr combination formula or using Pascal's Triangle.
Note: we only have 3 black chips, but because we put the chip back each time, it means we can get more than 3 black selections.
We'll also be using x = 1 to find the probability of getting exactly one red chip
P(x) = (binomialCoefficient)*(p)^x*(1-p)^(n-x)
P(x) = 5*(p)^x*(1-p)^(n-x)
P(1) = 5*(2/3)^1*(1-2/3)^(5-1)
P(1) = 0.0411523
The probability of getting exactly one red chip is roughly 0.0411523
Answer:
0.04112
Step-by-step explanation:
The total number of chips here are 6 + 3 = 9 chips
The probability of there being red chips would be 6/9 = 2/3rds = 0.67
According to the binomial theorem P(x) = C(n, x) * px * (1 - p)(n - x). We know that the process is repeated until 5 chips have been drawn, so n = 5. The probability that one red chip is selected would make x = 1, so we would have to solve for P(1).....substituting appropriate values;
P(1) = C(5, 1) * 0.67^1 * (1 - 0.67)^4
= 0.67 * 5.1(1 - 0.67)^4C
= 0.33^4 * 0.67 * 5.1C
= 0.33^4 * 3.417C
= (About) 0.04112...C
The probability that one chip was selected would be about 0.04112
The length, L, of a rectangle is 4 times its width, W. The perimeter of the rectangle is greater than 60
cm. Which inequality expresses all the possible lengths of the rectangle in centimeters? (Hint: P =

Answer:
w> 6
Step-by-step explanation:
Let w= the width
Let 4w = length
So then your equation becomes
2(w) + 2(4w) >60
Distribute
2w+8w > 60
Combine like terms
10w > 60
Divide by 10
w > 6
The CEO of a local tech company wants to estimate the proportion of employees that are pleased with the cleanliness of the breakrooms. She considers two methods of obtaining a sample of 600 employees from the 4,700 employees at the company. Part A: To make the process easier, the CEO considers surveying the first 600 employees who enter a company annual conference center. Identify the type of sampling method proposed and discuss why this sampling method might be biased. (5 points) Part B: The second method the CEO is contemplating involves a stratified random sample of 600 employees. The company has two campuses with male and female employees at each campus. What circumstances would stratification by campus give a more precise approximation of the proportion of employees who are satisfied with the cleanliness of the breakrooms than stratification by gender? (5 points)(10 points)
Answer:
Methods of obtaining a sample of 600 employees from the 4,700 workforce:
Part A: The type of sampling method proposed by the CEO is Convenience Sampling.
Part B: When there are equal number of participants in both campuses, stratification by campus would give a more precise approximation of the proportion of employees who are satisfied with the cleanliness of the breakrooms than stratification by gender. Another method to ensure that stratification by campus gives a more precise approximation of the proportion of employees who are satisfied with the cleanliness of the breakrooms than stratification by gender is to ensure that the sample is proportional to the proportion of each campus to the whole population or workforce.
Step-by-step explanation:
A Convenience Sampling technique is a non-probability (non-random) sampling method and the participants are selected based on availability (early attendees). The early attendees might be different from the late attendees in characteristics such as age, sex, etc. Therefore, sampling biases are present. All non-probability sampling methods are prone to volunteer bias.
Stratified sampling is more accurate and representative of the population. It reduces sampling bias. The difficulty arises in choosing the characteristic to stratify by.

Step-by-step explanation:
We hope this assignment came with an explanation. Otherwise, it's a meaningless image of numbers and circles.
__
We suspect the top circle is supposed to contain the product of the left and right circles, and the bottom circle is supposed to contain their sum.
When you're given only the product and sum, it can work reasonably well to look at the factorization of the product, and the sums of the factor pairs. It usually doesn't take long to find the sum of interest, if the numbers you're looking for are integers. (For the last problem, we had to look at several factor pairs before we found the right one.)

please help to find log 11 base 2. PLEASE HURRY UP INEED TO SUBMIT MY HOMEWORK TOMORROW.
HELP ME PLEASE
The value for log₂11 is 3.459.
To find the logarithm of 11 base 2, we need to determine the power to which we must raise 2 to obtain the value 11. In other words, we need to solve the equation 2^x = 11 for x.
Finding the exact value of log₂11 can be challenging since 11 is not a power of 2. Therefore, we can approximate the answer using numerical methods.
One way to approach this is by using the bisection method. We start by considering a lower bound and an upper bound for the value of x. Since 2^3 = 8 and 2^4 = 16, we can choose the interval [3, 4] as a starting point.
Next, we evaluate the midpoint of the interval, x = (3 + 4) / 2 = 3.5, and calculate 2^3.5 ≈ 11.314. Since this is larger than 11, we update our upper bound to 3.5.
We repeat the process by evaluating the midpoint of the new interval [3, 3.5], which gives us x = (3 + 3.5) / 2 = 3.25. Calculating 2^3.25 ≈ 10.63, we see that it is smaller than 11. Thus, we update our lower bound to 3.25.
We continue this iterative process, halving the interval each time, until we reach a satisfactory level of precision. After several iterations, we find that the value of x is approximately 3.459.
Therefore, an approximation for log₂11 is 3.459.

Answer: number 7. 7
Step-by-step explanation:
Simplifying
7X + 1 + -5X = 15
Reorder the terms:
1 + 7X + -5X = 15
Combine like terms: 7X + -5X = 2X
1 + 2X = 15
Solving
1 + 2X = 15
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '-1' to each side of the equation.
1 + -1 + 2X = 15 + -1
Combine like terms: 1 + -1 = 0
0 + 2X = 15 + -1
2X = 15 + -1
Combine like terms: 15 + -1 = 14
2X = 14
Divide each side by '2'.
X = 7

Determine the measures of the angles.
3
Answer:
Step-by-step explanation:
Shannon is designing a rectangular flag.
Therefore, all the interior angles of this flag measure 90°.
m∠1 + m∠2 = 90°
Since, ∠2 is 3 times as great as the measure of ∠1.
m∠2 = 3(m∠1)
Therefore, m∠1 + 3(m∠1) = 90°
4(m∠1) = 90°
m∠1 = 22.5°
m∠2 = 3(m∠1)
= 3(22.5)°
= 67.5°
m∠3 + m∠4 = 90° [Interior angle of a rectangle]
She thinks ∠3 and ∠4 are equal,
m∠3 = m∠4
m∠3 + m∠3 = 90°
2m∠3 = 90°
m∠3 = 45°
m∠4 = m∠3 = 45°
m∠2 = m∠6 [Opposite angles of a parallelogram are equal]
Therefore, m∠2 = m∠6 = 67.5°
Finally she wants the measure of ∠6 is half of the measure of ∠5.
m∠6 = [tex]\frac{1}{2}[/tex](m∠5)
67.5° = [tex]\frac{1}{2}[/tex](m∠5)
m∠5 = 2(67.5)°
= 135°
Answer: Shannon is designing a rectangular flag.
Therefore, all the interior angles of this flag measure 90°.
m∠1 + m∠2 = 90°
Since, ∠2 is 3 times as great as the measure of ∠1.
m∠2 = 3(m∠1)
Therefore, m∠1 + 3(m∠1) = 90°
4(m∠1) = 90°
m∠1 = 22.5°
m∠2 = 3(m∠1)
= 3(22.5)°
= 67.5°
m∠3 + m∠4 = 90° [Interior angle of a rectangle]
She thinks ∠3 and ∠4 are equal,
m∠3 = m∠4
m∠3 + m∠3 = 90°
2m∠3 = 90°
m∠3 = 45°
m∠4 = m∠3 = 45°
m∠2 = m∠6 [Opposite angles of a parallelogram are equal]
Therefore, m∠2 = m∠6 = 67.5°
Finally she wants the measure of ∠6 is half of the measure of ∠5.
m∠6 = (m∠5)
67.5° = (m∠5)
m∠5 = 2(67.5)°
= 135°

A turtle weights 153.7g what would be its weight in milligrams?
Answer:
153700
Step-by-step explanation:
Each morning librarians place 560 books on a book shelf in the school library. Each student that visits library that day takes exactly 3 books from this shelf. Let s be the number of students which visit library on a particular day. Let b be the number of books left on the shelf at the end of that day.
a.How does the number of books left on the shelf depend on number of students visiting library? Find formula for the function b(s).
b.There are 150 students studying in this school. Use this information to find the domain of the function b(s).
Answer:
A. 3(s)
B. 3(150) = 450 and 560 - 450 = 110 remaining books
Step-by-step explanation:
A. The number of leftover books on the shelf depends on the number of students because 3 books are taken per student, and the more students there are, the more books are taken. Specifically in sets of 3, gradually decreasing the total number of books and leaving a smaller amount leftover each time. Using b(s), we would replace "b" with 3 to represent the set of 3 books, since they are multiplied by the amount of students, giving us the formula 3(s).
B. Now that we know how many students are in the school library, in this case 150 is provided, we will also replace "s" with 150, the amount of students that are studying and taking 3 books each. So 3(150) = 450 books, and to find the leftover amount of b, we simply subtract 450 from 560. 560 - 450 = 110, meaning 110 represents the books left on the shelf.
The total number of books that'll be left on the shelf will be 110 books.
Number of books that are placed on the table = 560 books
Number of books taken by each student = 3 books each
Number of students that took books = s
Therefore, the number of books that are left on the shelf at the end of that day will be:
b = 560 - 3(s)
b = 560 - 3s
Therefore, when there are 150 students studying in this school, the number of books that will be left on the shelf will be:
b = 560 - 3s
b = 560 - 3(150)
b = 560 - 450
b = 110
There'll be 110 books left on the shelf.
