y=0.0714x-9.2682
y=1.2653x+14.452
y=2.5612x+4.9045
y=1.139x-6.7093
Answer: Choice A
y=0.0714x-9.2682
==============================================
Explanation:
I used GeoGebra (free graphing software) to find the line of best fit, aka the regression line. You can do so by hand, but I think it's tedious busywork and prefer to use technology whenever possible. Other graphing and spreadsheet programs are able to compute the regression line as well.
Check out the diagram below.
Which of the following customary units is the most appropriate unit to measure the capacity of a coffee pot?

The length of a 10-minute video is decreased by 45% when the video is edited. What is the length of the edited video?
Answer:
The edited video would now be 5 Minutes 50 Seconds
Step-by-step explanation:
10-4.5=5.5
To subtract any percentage from a number, simply multiply that number by the percentage you want to remain. In other words, multiply by 100 percent minus the percentage you want to subtract, in decimal form. To subtract 20 percent, multiply by 80 percent (0.8).
Step-by-step explanation:
its 5.5 mins
here are the methods
1-0.45= 0.55 0.55*10= 5.5
or
its
45/100= 0.45 0.45*10min= 4.5 10mins-4.5mins= 5.5 mins
Solve for x.
x ÷ 0.6 = 9.3

Answer:
x=5.58
Step-by-step explanation:
Answer: 5.58
All the other answers are wrong. You want to subtract both sides to get x alone. I used a calculator.

A water tank currently contains 275 gallons of water. The amount of water in the tank will decrease at a constant rate of 15 gallons per week.
Which function can be used to find t, the total number of gallons of water in the tank after w weeks?
F t = 15w - 275
G t = -15w + 275
H t = 275w - 15
J t = -275w + 15
The function that can be used to find t, the total number of gallons of water in the tank after w weeks will be t = -15w + 275
The initial volume of water in the tank is 275 gallons
The amount of water in the tank decreases at a constant rate of 15 gallons per week.
t = total number of gallons water in the tank after weeks
w = number of weeks
Therefore, the following equation/theory can be establish
The initial gallon of water in the tank is 275 gallons that means we should have positive value of 275 in the equationThe gallon of water reduces by 15 gallons each week which means 15 gallons will be subtracted from the initial gallons of water each week. This means we have to find the product of -15 and w(number of weeks).The equation will be
t = 275 - 15w
or
t = -15w + 275

Answer: B
Step-by-step explanation:
The table shows a set of values for x and y
a) Assume y = [tex]x^{2}[/tex]
[tex]1b=\frac{k}{1^{2} }[/tex] k = 1b
[tex]y=\frac{1b}{x^{2} }[/tex]
b) y = 25
[tex]x^{2}=\frac{16}{25}[/tex]
[tex]x=\sqrt{\frac{4}{5} ^{2} }[/tex]
x = ±[tex]\frac{4}{5}[/tex]
x > 0, x = 4/5
{ Equation }
y=16/x² is required equation for y in terms of x and x=4/5 when y=25.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The table of values are
x 1 2 3 4
y 16 4 16/9 1
Given that y is inversely proportional to square of x.
y=k/x²
Let us consider
y=16 and x=1
16=k/1
k=16.
y=16/x²
So y=16/x² is equation for y in terms of x
b) We need to find value of x when y=25
25=16/x²
Use cross multiplication
x²=16/25
Take square root on both sides
√x²=√16/25
x=±4/5
If x>0 , so x=4/5
Hence y=16/x² is required equation for y in terms of x and x=4/5 when y=25.

I'm having a bit of trouble finding out how to find the Domain of this function. Help please!
In general, the domain is the set of all x-values for the graph.
The issue here is that this isn't the graph of a function. A function has at most one y-value for each x-value and this graph has an infinite number of y-values for the single x-value of 1.
So, either your teacher is wanting you to say the domain is {1}, because that's the only x-value used by the graph, or they're wanting you to say this is a trick question, because this isn't the graph of a function.
The range is the set of all y-values, which is -9<y<9, but again, do they intend this to be a trick question?

Rachna borrowed a certain sum at the rate of 15% per annum. if she paid at the end of the two years Rs.1290 as interest Compounded annually, find the sum she borrowed.
Given info:
Compound Interest = Rs.1290
Rate of Interest = 15% p.a
Time = 2 years
Formula we have to know:-[tex] \dag{\underline{\boxed{\sf{C.I = P \bigg(1 + \dfrac{R}{100} \bigg)^{n} - 1}}}}[/tex]
Where
C.I = Compound Interest
P = Principle
R = Rate of Interest
N = Time
