The equation for the graphed quadratic function is:
y = -1*(x - 3)^2 + 2
How to write an equation for the function graphed?Here we have the graph of a quadratic equation. Remember that if the leading coefficient is a and the vertex is (h, k) then we can write:
y = a*(x - h)^2 + k
Here the vertex is at (3, 2) then we can write:
y = a*(x - 3)^2 + 2
We can see that it also passes through the point (1, -2), replacing these values we will get:
-2 = a*(1 - 3)^2 + 2
-2 = a*4 + 2
-2 - 2 = a*4
-4/4 = a = -1
Then the quadratic equation is:
y = -1*(x - 3)^2 + 2

Out of 1000 students who appeared for Cost accounting examinations,750 failed in maths,600 failed in accounts and 600 in costing,150 failed in both accounts and costing,450 failed in both maths and accounts,400 failed in both maths and costing.the students who failed all three subjects were 75.Prove that the above data is not correct
Answers
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.

Answer:
D. Machines, vehicles, furniture, and appliances are not considered liabilities. Liabilities are obligations or debts that a business owes to others. They are usually in the form of loans or accounts payable and represent money that must be paid in the future.
Machines, vehicles, furniture, and appliances are assets, which are resources that a business owns and that have monetary value. Assets can be sold to generate cash or used to produce goods or provide services. While assets can be used to secure loans, they do not represent a debt or obligation that must be paid in the future like a liability

How to write the linear equation?We want to find the equation of a line that passes through (1, 3) and (9, 8).
Remember that the slope of a line that passes through two points (x₁, y₁) and (x₂, y₂) is given by the equation:
slope = (y₂ - y₁)/(x₂ - x₁)
Here we know the two points (1, 3) and (9, 8).

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.
Answers
Hope this helps you :)
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.

Answers
There were 375 adult tickets sold and 316 student tickets for the school play.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Let the number of student tickets would be x and the number of adult tickets would be y
As per the question, we have a system of equations:
x + y = 691 ....(i)
x = y - 59 ....(ii)
Substitute the value of x = y - 59 in equation (i),
y - 59 + y = 691
2y = 691 + 59
2y = 750
y = 375
Substitute the value of y = 375 in equation (ii), and solve for x:

Will your battery capacity go down if you update your iphone?
Answers
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.
the company has to supply a minimum of 12 water tankers and a maximum of 16 water tankers to the construction site on weekdays except on Saturdays which is limited to the minimum of 4 water tankers a day. Calculate the total number of water loads that were supplied to the project on the constitution site by the water tanker in March 2022
Answers
Note that in order to solve the above, we had to assume a start date for the construction. Hence, by March 2022, a total number of liters supplied is 3,380,000 liters.
What is the rationale for the above response?
To solve the problem, we need to know how many weekdays are in March 2022. March 2022 has 23 weekdays (31 days - 4 Saturdays - 4 Sundays).
Since the company has to supply a minimum of 12 water tankers and a maximum of 16 water tankers to the construction site on weekdays, we can assume an average of 14 water tankers per weekday. Therefore, the total number of water tankers to be supplied on weekdays in March 2022 would be:
14 water tankers/day x 23 weekdays = 322 water tankers
On Saturdays, the company has to supply a minimum of 4 water tankers. Since there are 4 Saturdays in March 2022, the total number of water tankers to be supplied on Saturdays in March 2022 would be:
4 water tankers/day x 4 Saturdays = 16 water tankers
Therefore, the total number of water tankers to be supplied in March 2022 would be:
322 water tankers (weekdays) + 16 water tankers (Saturdays) = 338 water tankers.
Assuming each water tanker carries a load of 10,000 liters, the total volume of water supplied to the construction site in March 2022 would be:

1) Find the 9th term of the sequence:
60, 30, 15, ...
*
Answers
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.
