The sale price of the product would be Birr 105.80.
If the cost of the product is Birr 92 and the company has a policy of 15% mark-up on the cost, then the sale price can be found by adding 15% of the cost to the cost itself.
To calculate this, we can use the formula:
Sale price = Cost + Mark-up
where the mark-up is 15% of the cost.
Mark-up = 15% of Cost = 0.15 * 92 = Birr 13.80
So, the sale price = Cost + Mark-up = 92 + 13.80 = Birr 105.80.

Esteban has `3` kittens. According to the vet, each kitten is born with blue eyes and there is a `50\%` chance of it changing color once they reach three months.
Esteban decides to run a simulation using `3` coins, where heads represent the eyes changing color.
The table shows the results of his simulation.
Estimate the probability that at least one of Esteban’s kittens will still have blue eyes at three months old
There is an estimated probability of 0.875 (or 87.5%) that at least one of Esteban's kittens will still have blue eyes at three months old.
Let's use the complement rule to estimate the probability that at least one kitten will still have blue eyes at three months old:
P(at least one kitten with blue eyes) = 1 - P(no kitten with blue eyes)
To estimate P(no kitten with blue eyes), we can use the results of Esteban's simulation. We can see from the table that all three coins came up tails (representing no color change) in row 8, so that's one outcome where no kitten has blue eyes. There are a total of 2^3 = 8 possible outcomes, so the estimated probability of no kitten having blue eyes is:
P(no kitten with blue eyes) = 1/8 = 0.125
Therefore, the estimated probability that at least one kitten will still have blue eyes at three months old is:
P(at least one kitten with blue eyes) = 1 - P(no kitten with blue eyes) = 1 - 0.125 = 0.875
So, there is an estimated probability of 0.875 (or 87.5%) that at least one of Esteban's kittens will still have blue eyes at three months old.

Subtract 1/4- 5/14 = type an integer or fraction
Answer:
-3/28
Step-by-step explanation:
In order to subtract fractions you first have to get a common denominator. The common denominator between 4 and 14 is 28 since 4(7) = 28 and 14(2) = 28. Then multiply the top and bottom of (1/4) by (7/7) and (5/14) by (2/2). This gives a common denominator and since you multiply by a fraction equal to 1, it doesn't change the value. Therefore, we get 7/28 - 10/28 = -3/28.

A teacher asked three different students to write the conditions that would result in a triangle. Which of the following students listed conditions that would result in more than one triangle?
The condition that will result in more than one triangle is C. Student III.
How the conditions will result in more than one triangleThe conditions listed by the third student will result in more than one triangle because we are given all three angles. As a rule in math, some conditions will determine if there is more than one triangle. One of them is this:
Rule 1:
If all three angles of the triangle are given and they all add up to exactly 180°, it is possible to get more than one triangle. In the third option, we are given angles 62°, 36°, and 82°, so different triangles can be constructed. Also, they all add up to give 180°. The condition is satisfied.
Rule 2:
Also, as a rule, if we have two angles that do not add up to 180° and one side, then only one unique triangle can be obtained. This is the case for student A who is given angles A and B and a side length of 5cm. (ASA)

curl F =
(b) Find the divergence of the vector field.
div F =
(a) To find the curl of the vector field F(x, y, z), we first find its component functions:
F(x, y, z) = (5ex sin(y), 9ey sin(z), 2ez sin(x))
Then, we use the formula for the curl of a vector field:
curl F = (∂Fz/∂y - ∂Fy/∂z, ∂Fx/∂z - ∂Fz/∂x, ∂Fy/∂x - ∂Fx/∂y)
Plugging in the component functions of F(x, y, z), we get:
curl F = (2ez cos(x), -5ex cos(y), 9ey cos(z))
(b) To find the divergence of the vector field F(x, y, z), we use the formula for the divergence of a vector field:
div F = ∂Fx/∂x + ∂Fy/∂y + ∂Fz/∂z
Plugging in the component functions of F(x, y, z), we get:
div F = 5e^x sin(y) + 9e^y sin(z) + 2e^z sin(x)
(a) To find the curl of the vector field F(x, y, z) = (5e^x sin(y), 9e^y sin(z), 2e^z sin(x)), we need to compute the cross product of the del operator (∇) and F:
curl F = ∇ x F
curl F = ( (∂/∂y)(2e^z sin(x)) - (∂/∂z)(9e^y sin(z)), (∂/∂z)(5e^x sin(y)) - (∂/∂x)(2e^z sin(x)), (∂/∂x)(9e^y sin(z)) - (∂/∂y)(5e^x sin(y)) )
After computing the partial derivatives, we get:
curl F = ( 0, 5e^x cos(y) - 2e^z cos(x), 9e^y cos(z) - 5e^x cos(y) )
(b) To find the divergence of the vector field F(x, y, z), we need to compute the dot product of the del operator (∇) and F:

b. the same as
c. equal to
d. smaller than
A data set has many very large data values, then the mean will be larger than the median. The correct option is a.
In a dataset with large values, the mean is influenced by outliers and extreme values, whereas the median is not. The median is the value that divides the data into two equal halves, while the mean is calculated by summing up all values and dividing by the total number of values.
Thus, in a skewed dataset with large values, the mean tends to be pulled towards the larger values, resulting in a larger mean than the median. This effect is more pronounced in datasets with a high variance. Therefore, option (a) is the correct answer.

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.

What is the max/min of the quadratic equation in factored form: f(x) = 0. 5(x+3)(x-7)? Is it a maximum or a minimum? Show your workor explain your reasoning.
The quadratic equation in factored form: f(x) = 0. 5(x+3)(x-7) have a minimum point. The minimum value of the function is -11.
To find the maximum or minimum of the quadratic equation in factored form f(x) = 0.5(x+3)(x-7), we need to convert it to standard form by expanding the terms:
f(x) = 0.5(x² - 4x - 21)
f(x) = 0.5x² - 2x - 10.5
The coefficient of x² is positive, so the parabola opens upwards and we have a minimum point.
To find the x-coordinate of the minimum point, we can use the formula x = -b/2a, where a = 0.5 and b = -2:
x = -(-2)/2(0.5) = 2
So the minimum point is at x = 2. To find the y-coordinate, we can substitute x = 2 into the equation:
f(2) = 0.5(2)^2 - 2(2) - 10.5 = -11
Therefore, the minimum value of the function is -11.

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

Fred goes to Old Navy and buys two pairs of jeans for $17. 99 each, three shirts at $5. 99 each, and a pack of socks for $3. He has a coupon for 25% off his entire purchase. Sales tax is 6. 5%. What is the total cost after the discount and tax?
A: $43. 07
B: $39. 95
C: $45. 49
D: $60. 65
The total cost after discount and tax is $46.28.
To find the total cost after the discount and tax, we need to first find the subtotal before tax.
Fred bought two pairs of jeans for $17.99 each, so the cost of the jeans is $17.99 x 2 = $35.98.
He also bought three shirts at $5.99 each, so the cost of the shirts is $5.99 x 3 = $17.97.
The pack of socks costs $3.
The subtotal before discount is $35.98 + $17.97 + $3 = $57.95.
With the 25% off coupon, Fred gets a discount of $57.95 x 0.25 = $14.49.
The new subtotal after discount is $57.95 - $14.49 = $43.46.
Finally, we need to add the 6.5% sales tax.
The sales tax is $43.46 x 0.065 = $2.82.
The total cost after discount and tax is $43.46 + $2.82 = $46.28.

The latus rectum of an ellipse is 288/13 when the ellipse equation is given as [tex]x^2/169 + y^2/144 = 1[/tex]. Option A is correct.
The standard form of an ellipse equation is given as
[tex](x2/a2) + (y2/b2) = 1[/tex]
where :
a = lengths of the semi-major axes
b = length of semi-minor axes
The length of the chord through one of the foci that are perpendicular to the major axis is defined as the latus rectum of an ellipse.
From the given data the equation of the ellipse is given as :
x² / 169 + y² / 144 = 1
By comparing the standard equation and the given equation of the ellipse we get :
a² = 169
a = √169
[tex]a = 13[/tex]
b² = 144
b = √144
[tex]b = 12[/tex]
The distance between the center and one of the foci is given by
c = √(a² - b²)
= √(13² - 12²)
= 5
We can find the latus rectum by substuting a and b values in the latus rectum of an ellipse formula,
= 2×b²/a
= 2 × 12² / 13
= 288/13
Therefore, the latus rectum of an ellipse is 288/13.
