Randy is designing a circular garden that is 18 feet in diameter. He is buying plastic edging that costs $1. 50 per foot. He can only buy edging in whole-foot amounts. How much does it cost Randy to buy edging for his garden? Use 3. 14 for pie.
Answers
If the diameter of circular-garden is 18 feet, then it will cost Randy an amount of $85.50 to buy edges for his garden.
The "Circumference" of circle is defined as the "total-length" of the boundary or the outer edge of the circle.
The circumference formula is : Circumference = π × Diameter,
The "diameter" of garden is = 18-feet,
So, Circumference = 3.14 × 18 = 56.52 feet,
Since, Randy needs to buy plastic-edging to cover the entire circumference of garden, he needs to buy 56.52 feet of edging.
We know that, Randy can only buy edging in whole-foot amounts,
So, rounding up to the nearest whole foot, we get 57 feet,
The cost of edging is = $1.50 per foot,
So, "total-cost" for Randy to buy edging for his garden is,
⇒ Total Cost = (Cost per foot) × (Number of feet),
⇒ $1.50 × 57,
⇒ $85.50
Therefore, it will cost Randy $85.50 to buy edging for his circular garden.

d²v dt² v=2t² +7t+11 Find
Answers
The second derivative of v with respect to t, denoted as d²v/dt², is equal to 4
The second derivative of v with respect to t, we will differentiate v twice.
v = 2t² + 7t + 11
First, let's find the first derivative of v with respect to t (dv/dt):
dv/dt = d/dt (2t² + 7t + 11)
Using the power rule of differentiation, we differentiate each term separately:
dv/dt = 2(2t) + 7(1) + 0
dv/dt = 4t + 7
Now, let's find the second derivative of v with respect to t (d²v/dt²):
d²v/dt² = d/dt (4t + 7)
Again, using the power rule of differentiation, we differentiate each term separately:
d²v/dt² = 4(1) + 0
d²v/dt² = 4
Therefore, the second derivative of v with respect to t, denoted as d²v/dt², is equal to 4.

a leather store performs an observational survey of women walking through a mall. there were 30 women that walked by in an hour. of those women, 18 were carrying purses, 12 were wearing belts, and 6 were both carrying purses and wearing belts. what is the probability that a woman was wearing a belt, given that the woman was also carrying a purse?
Answers
The probability that a woman was wearing a belt given that she was also carrying a purse is 0.333 or 33.3%.
To find the probability that a woman was wearing a belt given that she was also carrying a purse, we need to use conditional probability.
We know that out of the 30 women observed, 18 were carrying purses and 6 were both carrying purses and wearing belts.
This means that the number of women carrying purses who were also wearing belts is 6.
Therefore, the probability that a woman was wearing a belt given that she was also carrying a purse is:
P(wearing a belt | carrying a purse) = number of women wearing a belt and carrying a purse / number of women carrying a purse
P(wearing a belt | carrying a purse) = 6 / 18
P(wearing a belt | carrying a purse) = 0.333
Given the information provided, we can determine the probability of a woman wearing a belt, given that she is also carrying a purse.
First, we need to find the number of women carrying a purse and wearing a belt, which is 6. There are 18 women carrying purses in total.
So, to find the probability, we will use the formula:
P(Belt | Purse) = (Number of women wearing belts and carrying purses) / (Number of women carrying purses)
P(Belt | Purse) = 6 / 18
P(Belt | Purse) = 1/3 or approximately 0.33
Therefore, the probability that a woman was wearing a belt, given that she was also carrying a purse, is 1/3 or approximately 0.33.

The base of a right circular cone has a radius of 4 inches and a slant height of 9 inches. If the radius and the slant height are multiplied by 6, by what factor is the surface area multiplied? A. 6 B. 36 C. 24 D. 54
Answers
Answer:
Correct option: B -> 36
Step-by-step explanation:
The surface area of a circular cone is given by the formula:
Surface area = pi * radius * (radius + slant height)
If the inicial radius is 4 in and the slant height is 9 in, we have:
Surface area = pi * 4 * (4 + 9) = 52pi in2
The radius and the slant height are multiplied by 6, so we have:
radius = 6 * 4 = 24 in
slant height = 6 * 9 = 54 in
So the new surface area is:
New surface area = pi * 24 * (24 + 54) = 1872pi in2
The factor of the surface areas is:
New surface area / Surface area = 1872pi / 52pi = 36

Find a degree 3 polynomial with real coefficients having zeros 5 and 4i and a lead coefficient of 1. Write P in expanded form
Answers
Given:
The degree of the polynomial = 3
Leading coefficient = 1
Zeros of the polynomial are 5 and 4i.
To find:
The expanded form of the polynomial.
Solution:
According to the complex conjugate root theorem, if a+ib is a zero of a polynomial, then a-ib is also a zero of that polynomial.
Here, zeros of the polynomial are 5 and 4i. It means the third zero of the polynomial is -4i. So, the factors of the polynomial are \((x-5),(x-4i),(x+4i)\).
The required polynomial is the product of its all factor and a constant which is equal to the leading coefficient. Here, the constant is 1. So, the required polynomial is
\(P(x)=1(x-5)(x-4i)(x+4i)\)
\(P(x)=(x-5)(x^2-(4i)^2)\)
\(P(x)=(x-5)(x^2+16)\) \([\because i^2=-1]\)
\(P(x)=(x-5)(x^2+16)\)
On further simplification, we get
\(P(x)=x^3+16x-5x^2-80\)
\(P(x)=x^3-5x^2+16x-80\)
Therefore, the required polynomial P is \(P(x)=x^3-5x^2+16x-80\).

Let A = A[1]... A[n] be an array of n distinct positive integers (the value of these integers could be very very large). An inversion is a pair of indices i and ; such that i Aj For example in the array(30000, 80000, 20000, 40000, 10000), the pair i = 1 and j = 3 is an inversion because A[1] = 30000 is greater than A[3] = 20000. On the other hand, the pair * = 1 and j = 2 is not an inversion because A[i] = 30000 is smaller than A[2] = 80000. In this array there are 7 inversions and 3 non-inversions, (a) Describe in one sentence the natural brite-force algorithm. (b) What is the complexity of the natural brute-force algorithm? (No explanation.) (e) Now give an O(n log ni)-time algorithm. (Hint: with some added bookkeeping this problem can be solved by an algorithm from class.)
Answers
(a) The natural brute-force algorithm for counting inversions in an array is to compare each pair of elements and count the inversions.
(b) The complexity of the natural brute-force algorithm is O(n²), where n is the size of the array.
(c) One possible algorithm to count inversions in O(n log n) time is the merge sort algorithm with some additional bookkeeping.
The steps of the algorithm are as follows:
1. Divide the array into two halves.
2. Recursively count the inversions in each half.
3. Merge the two sorted halves while counting the inversions.
4. Return the total count of inversions.
Here's the implementation of the algorithm:
def count_inversions(arr):
if len(arr) <= 1:
return arr, 0
mid = len(arr) // 2
left, inv_left = count_inversions(arr[:mid])
right, inv_right = count_inversions(arr[mid:])
merged, inv_merge = merge_and_count(left, right)
total_inversions = inv_left + inv_right + inv_merge
return merged, total_inversions
def merge_and_count(left, right):
merged = []
inversions = 0
i = 0
j = 0
while i < len(left) and j < len(right):
if left[i] <= right[j]:
merged.append(left[i])
i += 1
else:
merged.append(right[j])
j += 1
inversions += len(left) - i
merged += left[i:]
merged += right[j:]
return merged, inversions
# Usage example
arr = [30000, 80000, 20000, 40000, 10000]
sorted_arr, inversions = count_inversions(arr)
print("Inversions:", inversions)
The above algorithm has a time complexity of O(n log n) because it performs a divide-and-conquer approach using merge sort, and the merging step takes O(n) time while splitting the array recursively takes O(log n) time.

When testing the goodness of fit for the logistic regression model, if the obtained chi-square is less than the critical value, one would accept the null hypothesis, which states that the model fits the data well.
This means that there is no significant difference between the observed values and the values predicted by the model. However, it is important to note that this does not necessarily mean that the model is a perfect fit, as there may still be some minor discrepancies between the observed and predicted values. In addition, it is also important to consider other measures of model fit, such as the Hosmer-Lemeshow test, which assesses the agreement between the observed and predicted values for groups of individuals with similar predicted probabilities.

Always false
Sometimes true and sometimes false
Always true
Answers
The statement "For any y in the interval [-3,3], f(x) = y for some x in the interval [-5, -1]" is sometimes true and sometimes false.
The statement is asking whether there exists an x in the interval [-5, -1] such that f(x) takes on any value y in the interval [-3, 3]. Since f(x) is a continuous function, it means that the graph of the function has no breaks or jumps in that interval.
If we know that f(1) = 3, it tells us that the function takes on the value 3 at x = 1. However, we don't have information about the behavior of the function in the interval [-5, -1]. It's possible that the function could have values outside the interval [-3, 3] in that range, which would make the statement false. On the other hand, if the function remains within the interval [-3, 3] for all x in [-5, -1], then the statement would be true.
In conclusion, without more information about the behavior of the function in the interval [-5, -1], we cannot determine whether the statement is always true or always false. It depends on the specific behavior of f(x) in that interval.
