If natalie and her friends decide to rent 4 lanes at reguler cost for a party ten people need to rent shoes and 4 people are members what is the total cost for the party
Answers
The question is missing a tabular data. So, it is attached below.
Answer:
The total cost for the party is $74.50.
Step-by-step explanation:
Given:
Lanes rented at regular cost = 4
Cost of 1 lane rented at regular cost = $9.75
Cost of 1 lane rented for members = $7.50
Cost of 1 shoe rental at regular cost(non members) = $3.95
Cost of 1 shoe rental for members = $2.95
Since, lanes are rented at regular cost, we use unit rate at regular cost
So, cost of 4 lanes rented = [tex]4\times 9.75= \$ 39[/tex]
Now, out of 10 people who rented shoes, 4 are members. So, the number of non-members is given as:
Non members who rented shoes = 10 - 4 = 6
So, 4 members and 6 nonmembers rented shoes.
So, cost of 6 non members renting shoes = [tex]6\times 3.95=\$ 23.70[/tex]
Cost of 4 members renting shoes = [tex]4\times 2.95=\$ 11.80[/tex]
Total cost for the party is the sum of all the costs. This gives,
= 39 + 11.80 + 23.70
= 50.80 + 23.70
= $74.50
Therefore, the total cost for the party is $74.50.

Sleepy is eight years younger than scoopy. Doc is 5 times as old as scoopy. The sum of their age is 55. How old are each of them? This is the exact problem from worksheet.
Answers
Answer:
The age of Sleepy is 1 .
Then the age of Scoopy is 9.
The age of Doc would be 45.
Step-by-step explanation:
We have to find the ages of all the three people based on the given equations.
Let the age of Sleepy be x. Since Scoopy is 8 years older than Sleepy, the age of Scoopy would be (x+8).
Also Doc is 5 times as old as Scoopy so his age is 5(x+8).
Now the sum of the ages of all three is 55.
Writing equation for this,
x + x + 8 + 5(x+8) = 55
7x + 48 = 55
7x = 7
x = 1
So the age of Sleepy is 1 .Then the age of Scoopy is 9.
The age of Doc would be 45.
By solving the linear equations given by the problem, it is found that Scoopy is 10 years old, Sleepy is 2 years old, and Doc is 50 years old.
Explanation:This problem is a system of linear equations, a topic in the field of mathematics. The task is to find out the age of Sleepy, Scoopy, and Doc. Let's denote Scoopy's age as 'S', Sleepy's age as 'S - 8' (since Sleepy is eight years younger than Scoopy), and Doc's age as '5S' (since Doc is 5 times as old as Scoopy). The equations can be written as below:
Scoopy's age = SSleepy's age = S - 8Doc's age = 5SIt is known that the sum of their ages is 55, which gives us our second equation:
S + (S - 8) + 5S = 55
By solving this equation, we find that S = 10. So Scoopy is 10 years old. Accordingly, Sleepy is 10 - 8 = 2 years old and Doc is 5 * 10 = 50 years old.

Which of the following triangles is closest to being right? Explain your reasoning.
Answers
Answer: Second triangle.
Step-by-step explanation:
For this exercise you need to use the Pythagorean Theorem. Based on it, you know that in a right triangle:
[tex]a^2=b^2+c^2[/tex]
Where "a" is the hypotenuse of the right triangle and "b" and "c" are the legs.
In this case you can identify that the legs of the first triangle and the legs of the second triangle are equal. These are:
[tex]b=7\\c=3.3[/tex]
Knowing their values, you can substitute them into the Pythagorean Theorem and solve for "a":
[tex]a^2=(7)^2+(3.3)^2\\\\a=\sqrt{(7)^2+(3.3)^2}\\\\a=7.738[/tex]
Therefore, you can conclude that the triangle that is closest to being a right triangle is the second one.

A. y = −5/3x + 325/3 ~~
B. 20x + 12y = 1300
C. y + 12 = 20(x–1300)
D. 12y = 20x – 1300
Answers
Answer:
B
Step-by-step explanation:
In this case, we use variables to represent the the cost of the big and the smaller boxes. Let x be the selling price of the big boxes while y be the selling price of the bigger boxes.
The total selling price of the smaller boxes is 20x. The total selling price of the bigger ones is 12y.
Now we know he is making a profit of $1,300
Hence in equation form, all the information above can be represented as:
20x + 12y = 1,300
Neural networks, fuzzy systems, and evolutionary computation are all forms of __________, where systems develop intelligence through an iterative learning process.a. relational intelligenceb. conventional intelligencec. fuzzy logicd. computational intelligence
Answers
Answer:
d. computational intelligence
Step-by-step explanation:
Neural networks, fuzzy systems, and evolutionary computation are all forms of computational intelligence, where systems develop intelligence through an iterative learning process.
Computational intelligence (CI) is a machine intelligence which usually refers to the ability of a computer to learn or perform a specific task from data or experimental observation. This implies the systems have the ability to learn and generalize from examples and develop intelligence through an iterative process. Computer intelligence is also known as soft computing. The major Computational intelligence are Fuzzy logic, Neural networks and Evolutionary Computing. Presently, Computational Intelligence is an evolving field. New additions are evolving in addition to the three major CI. These new CI include soft computing like artificial endocrine networks, artificial life, ambient intelligence, cultural learning and social reasoning.
Neural networks, fuzzy systems, and evolutionary computation contribute to the field of computational intelligence, demonstrating adaptive learning capabilities and continuous improvement. Option d) is the correct answer.
Neural networks, fuzzy systems, and evolutionary computation are all forms of computational intelligence, where systems develop intelligence through an iterative learning process. Concepts such as evolution and adaptation, which originate in evolutionary biology, stretch to the domain of complex systems involving the development of adaptive, non-biological processes that have dynamic learning and creative abilities.
These systems are part of artificial intelligence, where computer systems learn from data to improve over time. These forms of artificial intelligence have been rapidly developing since the 1980s and are often associated with machine learning, suggesting a broad category where systems can adapt, process information, and optimize problems.
Many people believe that the daily change of price of a company's stock on the stock market is a random variable with mean 0 and variance 2. That is, if Yn represents the price of the stock on the n-th day, then Yn = Yn-1 + Xn, n > 1 where X1, X2, . . . are independent and identically distributed random variables with mean 0 and variance 2. Suppose that the stock's price today is 100. If 2 = 1, use CLT to approximate the probability that the stock's price will exceed 105 on the 10-th day?
Answers
Final answer:
Using the Central Limit Theorem, the probability that the stock's price will exceed $105 on the 10th day is calculated to be approximately 13.14%, assuming that the daily change of the stock price is a random variable with a mean of 0 and a variance of 2 and starting from a stock price of $100.
Explanation:
The question is asking to calculate the probability that a company's stock price will exceed $105 on the 10th day, given that the stock price today is $100 and that the daily change of price is a random variable with a mean of 0 and a variance of 2. To answer this, we can use the Central Limit Theorem (CLT) since we have a sum of independent and identically distributed random variables. According to the CLT, the sum of these random variables (or the stock price on the 10th day) will approximate a normal distribution as the number of days increases. For the 10th day, the expected price is the initial price (which is $100) plus 10 times the expected daily change (10*0 = 0), so the expected price is still $100. The variance of the sum of the daily changes is 10 times the variance of a single day (10*2), which equals 20, and the standard deviation is the square root of the variance, which is approximately 4.47.
We are trying to find the probability that the stock price is greater than $105. To do this, we convert the stock price into a z-score using the formula:
z = (X - μ) / σ
where X is the stock price we are interested in ($105), μ is the mean of the stock price on the 10th day ($100), and σ is the standard deviation (approximately 4.47). So we have:
z = (105 - 100) / 4.47 = 1.12
Using standard normal distribution tables or a calculator, we find that the probability of a z-score being greater than 1.12 is approximately 0.1314 (or 13.14%). Therefore, the probability that the stock's price will exceed $105 on the 10th day is about 13.14%.

What is the slope of the line that passes through (-3, 2) and (1, 2)?
Answers
Answer:
0
Step-by-step explanation:
Slope of a line which passes through two points (x1,y1) and (x2,y2) is given by:
\frac{y2-y1}{x2-x1}
(x1,y1) = (-3,2)
(x2,y2) = (1,2)
Substituting the values in the equation to determine the slope of the line:
= \frac{2-2}{1-(-3)}
= \frac{0}{4}
=0
So the slope of the given line is 0.
This is intuitively evident as well as the y coordinates of the two given points are the same.

On the track team, 35of the members are boys. Of these boys, 47 are sixth-graders. Of the sixth-grade boys on the team, 13 are runners. What fraction of the track team are sixth-grade boy runners?
Answers
Answer:
The number of runners is [tex]\dfrac{4 }{35}[/tex] of Total number of the member in team .
Step-by-step explanation:
Given as :
The Total number of the member in team = x
The number of boys in team = [tex]\dfrac{3}{5}[/tex] of x
I.e number of boys in team = [tex]\dfrac{3 x}{5}[/tex]
Again
The number of sixth-grade boys = [tex]\dfrac{4}{7}[/tex] of total boys in team
I.e The number of sixth-grade boys = [tex]\dfrac{4}{7}[/tex] × [tex]\dfrac{3 x}{5}[/tex]
Or, The number of sixth-grade boys = [tex]\dfrac{12 x}{35}[/tex]
Again
The number of runners = [tex]\dfrac{1}{3}[/tex] of number of sixth-grade boys
i.e The number of runners = [tex]\dfrac{1}{3}[/tex] × [tex]\dfrac{12 x}{35}[/tex]
Or, The number of runners = [tex]\dfrac{4 x}{35}[/tex]
So, The number of runners = [tex]\dfrac{4 }{35}[/tex] of Total number of the member in team
Hence,The number of runners is [tex]\dfrac{4 }{35}[/tex] of Total number of the member in team . Answer
The final agreed-to sample size is a trade-off between acceptable error and research cost.
Answers
Answer:
True
Step-by-step explanation:
Sample size selection is the act of choosing the number of observations or replicates to include in a statistical sample. The sample size is important in any empirical statistical study in which the goal is to make inferences about a population from a sample. The actual sample size used in a study is determined based on the time money and technical cost of data collection, and the need to have sufficient statistical accuracy.
Finding a balance between acceptable error and research cost gives rise to concepts like Confidence Interval and Margin of Error.

c. has a probability of n/(N-1) of being selected
d. has a probability of 1/N of being selected g
Answers
Answer:
a) has the same probability of being selected
Step-by-step explanation:
A simple random sampling means that each possible sample of size n has the same probability of being selected.
Then your answer is:
a) has the same probability of being selected
The definition of a simple random sampling method implies that each possible sample of a given size has an equally likely chance of being selected. Hence, option a. 'has the same chance of being selected' is the correct answer.
Explanation:The simple random sampling method is a statistical method used to select individual samples from a large population where each sample is given an equal chance of being selected. In a simple random sampling of size n from a finite population of size N, each possible sample of size n would have the same probability of being selected. Therefore, the correct answer is a. has the same probability of being selected.
It is crucial to note that the probability of a sample being selected is not dependent on its size (n) nor the total size of the population (N), as options b, c, and d suggest. Instead, it is determined solely by the sampling method, i.e., simple random sampling.

Calculate the area of an isosceles right triangle who's hypotenuse is 42–√ inches.
Answers
Answer:
A = 441 in²
Step-by-step explanation:
An isosceles right triangle is a triangle with two equals sides (the legs ). In this particular case the base of the triangle will be the length of one side and at the same time the height of the triangle will be the other leg. Hypotenuse as always is the opposite side to the right angle.
The area of a triangle is
A = (1/2) * b* h
If we are going to compute the area of such triangle we have to find the length of one side That will be the base of the triangle and at the same time that will be the height of the triangle.
In any right triangle hypotenuse is:
H² = L₁² + L₂² (1)
As was explain before in this particular case L₁ = L₂
Then
H² = L₁² + L₁² ⇒ H² = 2 L₁² H = √2 * L₁ ⇒ L₁ = 42/√2
Then area of the
A = (1/2)* ( 42/√2) * ( 42/√2 ) ⇒ A = 1/4 * (42)²
A = 441 in²
