The coordinates of the fourth vertex D = (3,−1.5).
What property this parallelogram has?A parallelogram has the following property AB=DC
AB=OB−OA=(3,3)−(1,5)=(2,−2)
DC=OC−OD=(8,3)−(a,b)=(2,−2)
OD=OC−DC=(8,3)−(2,−2)=(6,5)
Turn them into vectors. Position vector of point d
should be 6,5
To get the 2nd point, just do AD=BC
BC=OC−OB=(8,3)−(3,3)=(5,0)
AD=OD−OA=(a,b)−(1,5)=(5,0)
OD=OA−AD=(1,5)−(5,0)=(−4,5)
As long as the shape has four sides and two of them are parallel, and you know the length, this should work. For instance, a trapezium where AB=2DC/2CD:
A=(0,0),B=(2,0),C=(2,−1.5),D=(a,b)
AB=(2,0)DC=(2,−1.5)−(a,b)=12(2,0)(a,b)=(1,−1.5)
OR
AB=(2,0)CD=(a,b)−(2,−1.5)=12(2,0)(a,b)=(3,−1.5)
Thus, The coordinates of the fourth vertex D = (3,−1.5).

The weight of potato chips in a medium sized bag is stated to be 10 ounces. The amount that
the packaging machine puts in these bags is believed to be normally distributed with a mean of 10.2
ounces and a standard deviation of 0.12 ounces. Is it unusual for a bag to contain 9.8 ounces of
chips? Explain your answer.
Step-by-step explanation:
a normal distribution with mean m and standard deviation d gives us a few regular pieces of information.
for example, we know that 68.2% of all events are within the interval
m ± d
and 95.4% of all events are in the interval
m ± 2d
and 99.7% of all events are in the interval
m ± 3d
that means only 0.3% of all events are outside the interval
m ± 3d = 10.2 ± 3×0.12 = 10.2 ± 0.36
now, when a bag is filled with 9.8 ounces, it is 0.4 off the mean (10.2).
that means it is outside the 10.2 ± 0.36 interval and inside the 0.3% "exception" range.
you have to see it also that way : 0.3% means 3 out of 1000 bags are in that range.
so, yes, it is considered unusual.
What is the slope of line p? on a coordinate plane, a straight line goes through (negative 3, negative 2), (0, 0), and (3, 2).
Slope line formula is used for determining the slope of a line. Based on the given points, the slope of line is 2/3.
To find the slope of the line passing through the given points, we can use the slope formula, which states that the slope of a line passing through two points (x1, y1) and (x2, y2) is given by the expression:
slope = (y2 - y1) / (x2 - x1)
Using this formula, we can calculate the slope of the line passing through the three given points as follows:
slope = (2 - (-2)) / (3 - (-3)) = 4/6 = 2/3
Therefore, the slope of the line passing through the given points is 2/3.
Alternatively, we can observe that the three points are collinear and lie on the same straight line. We can use this fact to find the slope of the line by computing the rise over run between any two of the points. For example, using the points (0,0) and (-3,-2), we have a rise of 2 and a run of 3, so the slope is 2/3. This confirms that the slope of the line passing through the given points is 2/3.

Step-by-step explanation:
The value of the car depreciates by 35% each year, so we can calculate the depreciation for 2006 as follows:
Depreciation for 2006 = 0.35 * £5460 = £1911
The value of the car at the end of 2006 is:
£5460 - £1911 = £3549
Answer:
The depreciation rate:
Step-by-step explanation:
Step 1: Total depreciation = 35% x 2 years = 70%
Step 2: Find the value of the car at the end of 2006:
Value at the end of 2006 = 5460 x (100 - 70)/100 = 1638

Will your battery capacity go down if you update your iphone?
Unfortunately, a lot of software apps tend to use up battery life even if you aren't currently using the phone. This leads to the phone feeling more sluggish over time. To help combat this, it's helpful to clear out any unused apps and clear up the cache.
Even if software was perfectly written the most efficiently, and apps weren't intrusive, the physical nature of the battery itself has limitations. The capacity of the battery will slowly decay each time you charge or use your phone. Even just sitting idle it slowly loses capacity. This loss is very small that it's hard to detect. But add it up over time and the losses will get more noticeable. This is why you cannot simply charge a battery an infinite number of times. As with all things in life, there's a limit.
Summary: Yes the capacity will go down but ever so slightly. It depends how often the updates are done and what software is being updated. Ideally the updated software should be more efficient with the battery life. However, life isn't perfect and there will likely be flaws.

If we select all possible samples of a certain size from this population, then, on average, the value of the sample variance is 36.
What is a population?In Science, a population can be defined as a set of similar items or events that comprises every member of a group and from which a researcher, scientist, or experimenter, obtains or generates data for a statistical study.
What is a sample?In Statistics and science, a sample can be defined as a set of data that is collected from a population based on a well-defined sampling procedure.
In this context, we can reasonably infer and logically deduce that the sample variance on average would be equal to 36 because all possible samples of a certain size are selected from a population of 36 members.

1) Find the 9th term of the sequence:
60, 30, 15, ...
*
Answer:
Step-by-step explanation:
Let me explain step by step:
Determine the common ratio: We see that each term is half the previous term, so the common ratio is 1/2.
Write the formula for the nth term: We can use the formula for an infinite geometric series to find the nth term:
a_n = a_1 * r^(n-1), where a_1 is the first term (60), r is the common ratio (1/2), and n is the term number.
Plug in the values: We want to find the 9th term, so we plug in the values into the formula:
a_9 = 60 * (1/2)^(9-1)
Calculate the expression: We can simplify the expression by using the exponent rule for powers of 1/2:
a_9 = 60 * (1/2)^8
Divide the result by 256: We can simplify the expression further by dividing both sides by 256:
a_9 = 60 * 1/256
a_9 = 60 / 256
Get the final answer: We divide 60 by 256 to get the final answer:
a_9 = 0.234375
So the 9th term of the sequence is approximately 0.234375.

11. Equipment for your salon will cost anywhere from $7,000 to $10,000. How much money will you spend over the course of the first year with rent and equipment?
You have to spend $26,500 over the course of the first year with rent and equipment.
What is the equipment cost about?To calculate how much money you will spend over the course of the first year with rent and equipment, you need to add the cost of rent to the cost of equipment.
In a hypothetical scenario, Let's assume that the cost of rent for the first year is $1,500 per month.
To calculate the total cost of rent for the first year, you can multiply the monthly rent by the number of months in a year:
$1,500/month x 12 months = $18,000
So the total cost of rent for the first year is $18,000.
To calculate the total cost of equipment, you can take the average cost of the equipment (i.e., the midpoint of the given range) and assume that you will spend that amount:
($7,000 + $10,000) / 2 = $8,500
So the total cost of equipment is $8,500.
To calculate the total cost of rent and equipment for the first year, you can add the two costs together:
$18,000 + $8,500 = $26,500
Therefore, you will spend $26,500 over the course of the first year with rent and equipment.

Determine the largest power of 10 that is a factor of the following numbers (equivalently, the number of terminal 0's, using ordinary base 10 representation):(a) 50!.
(b) 1000!.
The largest power of 10 that is a factor of 1000! is 5^249, or 10^249.
(a) To find the largest power of 10 that is a factor of 50!, we need to count the number of factors of 5 in 50! since each factor of 5 contributes at least one factor of 10.
There are 10 multiples of 5 in 50!, namely 5, 10, 15, 20, 25, 30, 35, 40, 45, and 50. Each of these contributes one factor of 5. There are also 2 multiples of 25 (25 and 50), each of which contributes an additional factor of 5. Therefore, the total number of factors of 5 in 50! is 10 + 2 = 12.
Since each factor of 10 contains one factor of 5 and one factor of 2, we also need to count the number of factors of 2. It is clear that there are more factors of 2 than factors of 5, so we only need to count the factors of 5. Therefore, the largest power of 10 that is a factor of 50! is 5^12, or 10^12.
(b) To find the largest power of 10 that is a factor of 1000!, we follow the same reasoning as in part (a). The number of factors of 5 in 1000! is:
⌊1000/5⌋ + ⌊1000/25⌋ + ⌊1000/125⌋ + ⌊1000/625⌋ = 200 + 40 + 8 + 1 = 249

Answer: This data can be proven to be incorrect using the Principle of Inclusion-Exclusion.
The Principle of Inclusion-Exclusion states that for two events A and B, the number of elements in the union of A and B is equal to the sum of the number of elements in A and the number of elements in B minus the number of elements in their intersection.
Let's denote the number of students who failed in Maths as M, Accounts as A, and Costing as C.
From the information given, we have the following relationships:
M = 750
A = 600
C = 600
A ∩ C = 150
M ∩ A = 450
M ∩ C = 400
M ∩ A ∩ C = 75
Applying the Principle of Inclusion-Exclusion, the number of students who failed in at least one subject is:
M + A + C - (A ∩ C) - (M ∩ A) - (M ∩ C) + (M ∩ A ∩ C) = 750 + 600 + 600 - 150 - 450 - 400 + 75 = 925
However, the number of students who appeared for the exams is 1000, which means that the number of students who passed in all subjects should be 1000 - 925 = 75.
But we have already determined that the number of students who failed in all subjects is 75, which means that there are 75 students who are counted twice. This leads to a contradiction, and therefore the data given cannot be correct.
