If a trader is given a 15 percent discount on the factory price of certain goods, the factory price being ¢45000000, then
(I) The discount amount will be ¢6750000
(II) The final amount that the trader will have to pay to buy the goods will be ¢38250000.
As per the question statement, a trader is given 15 Percent discount on goods bought from a factory and the original price of the item bought from the factory is ¢45000000.
We are required to calculate the discount amount, and the final amount that the trader will have to pay to buy the goods.
To solve this question, we simply need to calculate 15 percent of 45000000, and then subtract the calculated discount amount from ¢45000000.
Therefore, 15 percent of ¢45000000 = ¢[(15/100) * 45000000]
= ¢(15 * 450000)
= ¢6750000
That is, on 15 percent discount on the factory price of certain goods, the factory price being ¢45000000, the discount amount is ¢6750000.
And, considering the discount of ¢6750000 on the factory price of ¢45000000, the final amount that the trader will have to pay to buy the goods = ¢(45000000 - 6750000)
= ¢38250000.
Percent: In mathematics, a percentage is a number or a ratio expressed as a fraction with 100 as the denominator, and is often denoted using the percent sign, "%".Discount: In Mathematics and basic accountancy, a Discount is an amount of rebate which is subtracted from the selling price of an item, and the customer can pay that rebated price to own the item.To learn more about percents and discounts, click on the link below.

Solve for x, y, and z
Using angle sum property we found that ∠ x = 113°, ∠y = 67° and ∠z = 49°
What is angle sum property of a triangle?The angle sum property of triangle states that the sum of all the interior angles of a triangle is 180°.
If ΔABC is a triangle then,
m ∠A + m ∠B + m ∠C = 180°
Given from the figure in the question that 28°, 39° and x° are interior angles of a triangle, then using angle sum property:
28° + 39° + x° = 180°
⇒ 67° + x° = 180°
⇒ x° = 180° - 67° = 113°
∠x and ∠y are on the same line same point therefore their sum will be 180°
⇒ x° + y° = 180°
⇒ 113° + y° = 180°
⇒ y° = 180° - 113° = 67°
Also an exterior angle of a triangle is equal to sum of interior opposite angles.
∴ y ° = 28° + 39° = 67°
Now, 64° , y° and z° are interior angles of same triangle from the figure in the question.
∴ Using angle sum property,
64° + y° + z° = 180°
⇒ y ° + z° = 180° - 64° = 116°
⇒ y° + z° = 116°
⇒ z° = 116° - y° = 116° - 67° = 49°
Therefore ∠x, ∠y , ∠z are 113° , 67° and 49° respectively

Alan sees this offer.
Refurbished phone
45% OFF
Now only £88
How much was the phone before the discounted price?
The cost of the phone before the discounted price is $160.
Given that, Refurbished phone 45% OFF now only £88.
What is the discount?Discount is the reduction in the price of goods or services offered by shopkeepers at the marked price. The List price or Marked price is the price of an article as declared by the seller or the manufacturer, without any reduction in price. Selling price is the actual price at which an article is sold after any reduction or discounts in the list price.
Let the original price of the phone be x.
Now, x - 45% of x = 88
⇒ x - 45/100 × x = 88
⇒ x - 0.45x = 88
⇒ 0.55x = 88
⇒ x = 88/0.55
⇒ x = 160
Therefore, the cost of the phone before the discounted price is $160.

A lift ratio of 1.52 implies that identifying a person who purchases coffee and a breakfast sandwich is 52% better than guessing that a random person will purchase a breakfast sandwich.
What is the lift ratio about?Stronger relationships are indicated by higher lift values.We divide the confidence ratio by the support of the consequent to arrive at the lift ratio.
Lift ratios greater than one are typically thought to imply a significant link between the components. Lift ratios below 1 indicate that a purchase of the items is unlikely. Lift is simply the ratio of target response divided by the average response.

The probability that the diameter of a selected bearing is greater than 152 millimeters is 64.05%.
What is termed as the z-score?The Z-score indicates how far the measure deviates from the mean. After determining the Z-score, we examine the z-score table to determine the p-value affiliated with this z-score. This p-value represents the probability that the measure's value is less than X, or the percentile of X.For the given question;
The data for the ball bearing is given as-
mean diameter μ = 139 millimetersvariance σ = 36 millimeterssample mean x = 152 millimetersZ-score = (x - μ)/σ
Put the values;
z = (152 - 139)/36
z = 0.36
P(x > 125) = P(z > 0.36), see p values from z table for 0.36.
P(x > 125) = 0.6405
P(x > 125) = 64.05%
Thus, the probability that the diameter of a selected bearing is greater than 152 millimeters is 64.05%.

find the midpoint using the midpoint formula
with A (- 2, 0 ) and B (0, 6 )
midpoint = ( [tex]\frac{-2+0}{2}[/tex] , [tex]\frac{0+6}{2}[/tex] ) = ( [tex]\frac{-2}{2}[/tex] , [tex]\frac{6}{2}[/tex] ) = (- 1, 3 )
find the gradient m of AB using the gradient formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = A (- 2, 0 ) and (x₂, y₂ ) = B (0, 6 )
m = [tex]\frac{6-0}{0-(-2)}[/tex] = [tex]\frac{6}{0+2}[/tex] = [tex]\frac{6}{2}[/tex] = 3
given a line with gradient m then the gradient of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{3}[/tex]
the equation of a line in gradient- slope form is
y = mx + c ( m is the gradient and c the y- intercept )
here m = - [tex]\frac{1}{3}[/tex] , then
y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation
to find c substitute (- 1, 3 ) into the partial equation
3 = [tex]\frac{1}{3}[/tex] + c ⇒ c = 3 - [tex]\frac{1}{3}[/tex] = [tex]\frac{8}{3}[/tex]

The term "markup" describes the discrepancy between a product's selling price and its actual cost. It is specified as a percentage over the price. In other words, the seller makes a profit when the price of the commodity or service is higher than the overall cost. A unit's gross profit, which is the sales price less the cost to create or buy it for resale, is divided by its cost to determine the markup %. The markup percentage is computed as (12 - 8) / 8 and is equal to 50% if an item costs the business $8 to produce but is sold for $12.

What is meant by length of side?By dividing the base's length by its height, one may calculate any quadrilateral's surface area. We can conclude that all of the sides are the same length because the shape is square. Using the square root of the area to determine the length of one side, we can then work backwards from this information. A square has four sides, thus to determine the length of one side, divide the perimeter by 4. Assumed Area: Since s2 is the formula for a square's area and that number corresponds to one of its sides, you must get the square root of the area. A side is the line segment that connects two vertices of a shape or two-dimensional figure according to the definition of geometry.
Length of SU
