The farmer would have made a profit of 5% if he had sold the goat for 2100 shillings.
Let's use the given terms and find out the percentage profit if the farmer had sold the goat for 2100 shillings.
Calculate the cost price of the goat
We know that the farmer made a loss of 28% by selling the goat for 1440 shillings. Let's represent the cost price as "CP".
We can write the equation:
[tex]CP \times (1 - loss% ) = selling price (SP)[/tex]
[tex]CP \times (1 - 0.28) = 1440[/tex]
Solve for CP
[tex]CP \times 0.72 = 1440[/tex]
CP = 1440 / 0.72
CP = 2000 shillings
Calculate the percentage profit
Now we want to find out the percentage profit if the farmer had sold the goat for 2100 shillings.
We can write the equation:
[tex](SP_{new - CP)} / CP \times 100 = profit[/tex]
[tex](2100 - 2000) / 2000 \times 100 = profit%[/tex]
[tex]100 / 2000 \times 100 = profit%[/tex]
5% = profit%.

The answer is option B: (0.221-0.27).
Using the formula for a confidence interval for a proportion:
p± z*√(p(1-p)/n)
where p is the sample proportion (12/45 = 0.267), z* is the z-score for the desired confidence level (99% corresponds to a z-score of 2.576), and n is the sample size (45).
Substituting the values, we get:
0.267 ± 2.576*√(0.267(1-0.267)/45)
which simplifies to:
0.267 ± 0.195
Therefore, the 99% confidence interval for the true proportion of times the number cube would land with a six facing up is (0.072, 0.462).
So the answer is option B: (0.221-0.27).

2. ⊙O and ⊙P are given with centers (−2, 7) and (12, −1) and radii of lengths 5 and 12, respectively. Using similarity transformations on ⊙O, prove that ⊙O and ⊙P are similar
Answer: Finally, translate the circles back to their original positions. This will not change their similarity. Therefore, ⊙O and ⊙P are similar.
Step-by-step explanation:
To construct a circle circumscribed about triangle △DEF, follow these steps:
Draw the perpendicular bisectors of the sides of the triangle. Each bisector should intersect the opposite side of the triangle at a point.
Find the point of intersection of any two perpendicular bisectors. This point is the center of the circle.
Measure the distance from the center to any of the vertices of the triangle. This distance is the radius of the circle.
Draw the circle with the center and radius found in the previous steps. The circle should pass through all three vertices of the triangle.
To prove that ⊙O and ⊙P are similar using similarity transformations, follow these steps:
Translate both circles so that their centers coincide with the origin. This will not change their relative positions.
Scale one of the circles by a factor equal to the ratio of the radii of the two circles. This will make the two circles have the same size.
Since both circles are centered at the origin and have the same size, they must be similar. This is because any two circles with the same size are either congruent or similar.
Finally, translate the circles back to their original positions. This will not change their similarity. Therefore, ⊙O and ⊙P are similar.

Suppose that your foot length L in inches is related to your height h in inches by L=(3/4)h^0. 5
In one (non-leap) year, you have a growth spurt in which you grow from 64 inches to 69 inches. For simplicity of modeling, assume that your height changes at a constant rate throughout the year. What was the fastest rate of growth that your foot experienced during this time?
Answer for inch/year. Three digits after the decimal points after round off.
The fastest rate of growth that the foot experienced during the year is approximately 0.554 inches/year.
We can use the given relationship between foot length L and height h to determine the rate of change of foot length with respect to time. Taking the derivative of L with respect to time t, we have dL/dt = (3/4) * 0.5 * h^(-0.5) * dh/dt. We can then substitute the given values of L and h at the beginning and end of the growth spurt to find dh/dt.
At the start, h = 64 inches and L = (3/4) * 64^0.5 = 9 inches. At the end, h = 69 inches and L = (3/4) * 69^0.5 = 9.89 inches.
Solving for dh/dt, we have dh/dt = 2.4 inches/year. Substituting this value into the expression for dL/dt, we get dL/dt = (3/4) * 0.5 * 69^(-0.5) * 2.4 = 0.554 inches/year (rounded to three decimal places). Therefore, the fastest rate of growth that the foot experienced during the year is approximately 0.554 inches/year.

You are buying fabric to make a patio umbrella in the shape of a regular hexagon. The res fabric costs $s. 75 per square yard and the white fabric costs $2i50 per square yard. You can only order whole numbers of square yards of fabric. What will be the cost of the fabric
The cost of the fabric will be $55.63.
To find the cost of the fabric, you need to first determine the total area of the fabric needed to make the patio umbrella. Since the patio umbrella is in the shape of a regular hexagon, it can be divided into six congruent equilateral triangles. The formula for the area of an equilateral triangle is A = (sqrt(3)/4)*s^2, where s is the length of one side of the hexagon.
Let's assume the length of one side of the hexagon is x. Then the area of one of the equilateral triangles is A = (sqrt(3)/4)x^2. Since there are six of these triangles in the hexagon, the total area of the hexagon is 6A = 6(sqrt(3)/4)*x^2 = (3sqrt(3)/2)*x^2.
To determine the amount of orange fabric needed, you can multiply the area of the hexagon by the number of square yards in one square foot and round up to the nearest whole number of square yards. Similarly, you can do the same for the white fabric.
Let's say the hexagon has a side length of 6 feet, so x=6ft. Then the area of the hexagon is (3sqrt(3)/2)*(6ft)^2 = 93.53 square feet. Converting square feet to square yards gives 10.39 square yards. Therefore, you need to order at least 11 square yards of each fabric.
The cost of the orange fabric is $s. 75 per square yard, so 11 square yards will cost 11 * $s. 75 = $28.13. The cost of the white fabric is $2.50 per square yard, so 11 square yards will cost 11 * $2.50 = $27.50. Therefore, the total cost of the fabric will be $28.13 + $27.50 = $55.63.

The completed table of equivalent ratios would be:
13.5 square meters : 3 liters of paint
4.5 square meters : 1 liter of paint
45 square meters : 10 liters of paint.
To find the missing ratios, we need to set up proportions using the given information.
13.5 square meters is covered by 3 liters of paint, so we can write:
13.5/3 = ?/1
To solve for the missing ratio, we can cross-multiply:
13.5 x 1 = 3 x ?
? = (13.5 x 1) / 3
? = 4.5
So, 4.5 square meters can be covered by 1 liter of paint.
To find the last missing ratio, we can use the same method:
13.5/3 = ?/10
10 x 13.5 = 3 x ?
? = (10 x 13.5) / 3

The square pyramid has a base with an area of 64 cm and a slant height of 9 cm. What is the height of the pyramid
To find the height of the square pyramid, we will use the Pythagorean theorem. Given the area of the base is 64 cm² and the slant height is 9 cm, let's first find the side length of the base.
Since it's a square, the area of the base is side length squared (s²). Therefore, s² = 64 cm². Taking the square root of both sides, we get s = 8 cm.
Now, let the height be h and use the Pythagorean theorem with the side length (8 cm) and the slant height (9 cm):
h² + (s/2)² = (slant height)²
h² + (8/2)² = 9²
h² + 4² = 81
h² + 16 = 81
h² = 65
Taking the square root of both sides:
h = √65 cm ≈ 8.06 cm

The Ratio Test is inconclusive, but the series converges conditionally by another test or tests. Enter the letter for your choice here:?
The correct answer is F.
How to find the convergence or divergence of a series?To apply the Ratio Test, we need to compute:
L = lim(n → ∞) |a(n+1)/a(n)| = lim(n → ∞) |(8(2n+3) + 4)/(8(2n+1) + 4)|
Dividing numerator and denominator by 8(2n+3), we get:
L = lim(n → ∞) |(1 + 1/(2n+3))/(1 + 1/(2n+1))|
As n → ∞, both fractions approach 1, so the limit simplifies to:
L = lim(n → ∞) 1 = 1
Since L = 1, the Ratio Test is inconclusive. We cannot say anything about the convergence or divergence of the series from this test alone.
Therefore, the correct answer is F. The Ratio Test is inconclusive, but the series may converge conditionally by another test or tests.

Select the correct choice below and, if necessary, fill in the answer box to complete your choice A. The critical number(s) is/are x = (Use a comma to separate answers as needed) B. There are no critical numbers
The critical numbers of f are x = -5 and x = 5.
(A) To find the derivative f'(x), we differentiate f(x) = x³ - 75x - 2 with respect to x:
f'(x) = 3x² - 75
(B) There are no partition numbers for f' as partition numbers are related to integer partitions, which are not applicable in this context.
(C) To find the critical numbers of f, we set f'(x) equal to 0 and solve for x:
3x² - 75 = 0
x² = 25
x = ±5
So the critical numbers of f are x = -5 and x = 5.

COMPARE BY USING <,>,=,<=,>=
The product of the middle two sums is greater than or equal to the product of the least and the greatest of the sums.
How can the two products be compared?To compare two products, we need to compare the values of the products using the comparison operators (<, >, <=, >=, or =).
We can start by finding the sums of the original numbers (0, 1, 2, 3):
Sum of the original numbers = 0 + 1 + 2 + 3 = 6
Now, we add the number k to each of the numbers:
Sum of the new numbers = (0 + k) + (1 + k) + (2 + k) + (3 + k)
= (0 + 1 + 2 + 3) + 4k
= 6 + 4k
So, the new sums range from 6 + 4k (the smallest) to 9 + 4k (the largest).
The product of the least and the greatest of the sums is:
(6 + 4k) × (9 + 4k) = 54 + 60k + 16k^2
The product of the middle two sums is:
(7 + 4k) × (8 + 4k) = 56 + 60k + 16k^2
Comparing the two products using the comparison operators:
54 + 60k + 16k^2 < 56 + 60k + 16k^2 (since 54 < 56)
or
54 + 60k + 16k^2 <= 56 + 60k + 16k^2 (since the products are equal when k=0)
In conclusion, the product of the middle two sums is greater than or equal to the product of the least and the greatest of the sums.

A hotel offers two activity packages. One costs $192 and includes 3h of horseback riding and 2h of parasailing. The second costs $213 and includes 2h of horseback riding and 3h of parasailing. What is the cost for 1h of each activity?
Answer:
Step-by-step explanation:
Step-by-step explanation:
let's assumed that
x = 1h of horseback
y = 1h of parasailing
3h of horseback = 3x
2h of parasailing = 2y
and
2h of horseback = 2x
3h of parasailing = 3y
if
3x + 2y = 192
2x + 3y = 213
to find y we have to remove the x
(3x + 2y = 192) × 2
(2x + 3y = 213) × 3
6x + 4y = 384
6x + 9y = 639
___________ -
-5y = -255
y = 51
substitute y to any equation to find x
3x + 2y = 192
3x + 2(51) = 192
3x + 102 = 192
3x = 192 - 102
3x = 90
x = 30
so the answers are 1h of horseback = $30 and 1h of parasailing = $51
