the residents of a city voted on whether to raise property taxes. the ratio of yes votes to no votes was to . if there were no votes, what was the total number of votes?
The total number of no votes are 4422.
What is ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Given: The ratio of yes votes to no votes is 5 to 6 i.e.
yes votes /no votes = 5/6
It means there are total 11 votes ( 5 votes for yes and 6 votes for no)
which gives
no votes/total votes= 6/11---(i)
But in the given question total votes are 8107,
so let us consider there are x votes for no which implies
no votes/total votes= x/8107
From (i), we have
x/8107 = 6/11
⇒ x = 6*8107/11 = 4422.

What is Fibonacci Sequence?
A series in which each number is the sum of the two numbers before it is known as the Fibonacci Sequence. We must specify values for the first two terms in order to complete the Fibonacci Sequence. In the Fibanocci sequence we can find next term by adding previous terms.
Here the given Fourth term = 30 and Fifth term = 49.
Here second and third terms are x and y. Let us take first term as a.
We know that the Fibonacci sequence is sum of previous terms.
The sequence are,
=> a , x , y , 30 ,49 ,...
Here Fourth term = 30
=> second term + third term = 30
=> x+y = 30----->1
Now the fifth term is third term + fourth term = 49
=> y+30 =49
=> y =19.
Put y=19 into 1 then,
=> x+19=30
=> x = 30-19 =11
Now third term is first term+second term = third term
=> a+x =y
=> a+11=19
=> a =19-11 =8.
b) First term of the Fibonacci sequence is 8.
c) Third term = first term+second term
=> y = first term +x
=> First term = y-x.
Fourth term = Second term+third term
=>Fourth term = x+y
Fifth term = third term+fourth term
=> Fifth term = y+30.
Therefore the given Fibonacci sequence ,

you are asked to help with the radiodating of a plant based sample excavated from an archaeological site. the rate of 14c decay in the sample is 73.0% of the 14c decay rate in a living plant. what is the estimated age of the archaeological sample? (the half-life for 14c is 5730 years.)
The estimated age of the archaeological sample as calculated from the given data is = 2622.58333 years
Half life given is 5730
t₆.₅ = Ln2/k
k= ln 2/ 5730
The rate constant ,
k = 0.00012 year⁻¹
Given that 73 % of the 14C remains
then |A1|/|A2| = 0.73
As we know ,
|A1|/|A2| = e ⁻₍kt₎
Hence, on solving the equation we get ,
ln(0.73)= -0.00012t
t = -0.31471/ -0.00012
= 2622.58333 years
Half-life (symbol t½) is the time required for a quantity (of substance) to reduce to half of its initial value. The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms survive. The term is also used more generally to characterize any type of exponential (or, rarely, non-exponential) decay.
For example, the medical sciences refer to the biological half-life of drugs and other chemicals in the human body. The converse of half-life (in exponential growth) is doubling time.

Given,
Making an interval estimate for the population mean requires making the following assumptions about the population:
a. The population is thought to have a normal distribution.
b. The central limit theorem is presumptively true.
The distribution of a variable's values is described by a normal distribution. There are 50% of the data to the left and 50% to the right of the mean in this probability distribution, which is symmetrical about the mean. The majority of the data are centered around the mean, meaning that they are more likely to occur or be located close to the mean than distant from it. A bell curve will represent the normal distribution's graph form. Mean = mode = median describes a normal distribution.
According to the Central Limit Theorem, when a variable does not follow a normal distribution, repeated random samples from the population will result in sample means that are normally distributed, regardless of the underlying distribution of the sample. This indicates that as the sample size increases, the sampling distribution of the sample means moves closer to a normal distribution.

Step-by-step explanation:
Since both base and perpendicular are the same, let's denote both of them by one variable i.e. x
Using Pythagoras Theorem because it is a right-angled triangle.
[tex](Hypotenuse)^2=(Base)^2+(Perp)^2[/tex]
Where,
Base, Perp = x
Hypotenuse = [tex]2\sqrt{2}[/tex]
So,
[tex](2\sqrt{2})^2=(x)^2+(x)^2 \\\\4 \times 2 = x^2+x^2\\\\8 = 2x^2\\\\Divide \ both \ sides \ by \ 2\\\\4 = x^2\\\\Take \ sqrt\\\\2 = x \\\\x = 2[/tex]

The Bonferroni technique is an easy procedure that permits the construction of several confidence intervals or comparison statements while maintaining a constant overall confidence coefficient.
Here,
Divide the initial alpha level (often set to 0.05) by the total number of tests to make the adjustment. The result of the calculation is a Bonferroni-corrected p value, which will serve as the new cutoff point for classifying a single test as significant.

where x = score, σ = standard deviation, μ = mean
Now z-score corresponding to 98th percentile is 2.06
substituting the values in the above equations,
2.06 = (x - 0.959) / 1.74

What is the equation of a line that is parallel to 2x 3y = 3 and passes through the point (3, −4)? enter your answer in the box.
The correct answer is the equation of the line is y = [tex]-\frac{2}{3} x - 2[/tex]
Given the equation of the parallel line is 2x + 3y = 3
and the required line passes through the point (3, -4) where x is 3 and y is -4
We can write the given equation as:
⇒ 3y = 3 - 2x
Dividing both sides by 3
[tex]y = 1 - \frac{2x}{3}[/tex]
On comparing this equation with y= mx+b, thus m = [tex]-\frac{2}{3}[/tex] and the slopes of parallel lines are always equal.
Using the point slope form, we will derive the equation of line
⇒ [tex]y-y_1 =m ( x- x_1)[/tex]
⇒ [tex]y- (-4) = -\frac{2}{3} (x-3)[/tex]
⇒ [tex]y+4= -\frac{2}{3} (x) - \frac{2}{3} (-3)[/tex]
⇒ [tex]y = -\frac{2}{3} (x) +2-4[/tex]

Find the equation of the inverse for each function. State which of the following inverses are functions.
a) f(x)=1/(2x)-3
b) f(x)=4x²-5
c) A(r)=4 (Pi)r²
The inverse of the functions are f⁻¹(x) = 1/2(x + 3), f⁻¹(x) = 1/2√(x + 5) and A⁻¹(r) = 1/2√(r/pi)
How to determine the inverse of the functions?Function (a)
This function is given as
f(x)=1/(2x)-3
The function needs to be represented as an equation
So, we have
y = 1/(2x) - 3
Swap the positions of x and y
x = 1/(2y) - 3
So, we have
1/(2y) = x + 3
Take the inverse of both sides
2y = 1/(x + 3)
Divide by 2
y = 1/2(x + 3)
So, the inverse function is
f⁻¹(x) = 1/2(x + 3)
Function (b)
This function is given as
f(x)=4x²-5
The function needs to be represented as an equation
So, we have
y = 4x²-5
Swap the positions of x and y
x = 4y² - 5
So, we have
4y²= x + 5
Divide both sides by 4
y²= 1/4(x + 5)
Take the square roots
y= 1/2√(x + 5)
So, the inverse function is
f⁻¹(x) = 1/2√(x + 5)
Function (c)
This function is given as
A(r) = 4(pi)r²
The function needs to be represented as an equation
So, we have
y = 4(pi)r²
Swap the positions of r and y
r = 4(pi)y²
So, we have
y²= r/(4pi)
Take the square roots
y = 1/2√(r/pi)
So, the inverse function is
A⁻¹(r) = 1/2√(r/pi)

Solve the equation 2cos x+ √2=0 for solutions of x in the interval [0°, 360°).
The solutions of x in the interval [0°, 360°) are 3[tex]\pi[/tex]/4 and 5[tex]\pi[/tex]/4 respectively.
What is a quadrant?
The quadrant is the area that is bounded by the point where the X and Y axes connect.
A plane is split into four sections in the cartesian system, the X-axis, a horizontal line, and the Y-axis, a vertical line. The term "quadrant" refers to these four areas.
Given, 2cos x + √2 = 0
or, 2cos x = -√2
or, cos x = -√2/2 = -1/√2 = - cos ([tex]\pi /4[/tex] )
As the given cos(x) is negative, then it must lie in quadrants II and III respectively for the given interval [0°, 360°).
Then, cos x = cos ([tex]\pi[/tex] - [tex]\frac{\pi}{4}[/tex]) and, cos x = cos ([tex]\pi +\frac{\pi }{4}[/tex])
or, x = 3[tex]\pi[/tex]/4 or, x = 5[tex]\pi[/tex]/4
Hence, the required solutions of x are 3[tex]\pi[/tex]/4 and 5[tex]\pi[/tex]/4.
