The length of the chord is 6
What is a circle simple definition?Simply said, a circle is a rounded form without any edges or line segments. It has the geometric form
What is the General Equation of Circle?The circle's general equation is written as follows: x2 + y2 + 2gx + 2fy + c = 0. The center of the circle in this general form of the equation of a circle is (-g, -f), and its radius is given by r = g2+f2cg2+f2c.
What is C in the General Equation of Circle?The circle's general equation is written as follows: x2 + y2 + 2gx + 2fy + c = 0. The coordinates of the circle's center and radius are determined using this general form. The equation in this case represents a circle that does not pass through the origin because c is a constant term.
We possess
4x2+4y2−12x+32y=27…(1)
We shall have y=0 when the specified circle intersects the x-axis, therefore
4x2+4y2−12x+32y=27
=>4x2−12x=27
=>4x2−12x−27=0…(2)
The answers to (2) are:
x1=−3/2
x2=9/2
Thus, the supplied circle intersects the x-axis at the following points:
A(−3/2,0) and B(9/2,0)
The length of the chord we want is defined as the distance d between these sites. The well-known formula for calculating the distance between points A and B is used to calculate the distance d:
d=root((9/2−(−3/2))^2+(0−0)^2)

A population has a mean of 180 and a standard deviation of 36. A sample of 84 observations will be taken. The probability that the sample mean will be between 181 and 185 is?.
The probability that the sample mean will be between 181 and 185 is 0.3039.
Given,
The mean of a population, μ = 180
Standard deviation, σ = 36
Number of sample observations, n = 84
We have to find the probability that the sample mean will be between 181 and 185;
Lets convert 181 and 185 into z scores;
z = (x - μ) / (σ/√n)
x = 181z = (181 - 180) / (36/√84)
z = 1/3.93
z = 0.25
x = 185z = (185 - 180) / (36/√84)
z = 5 / 3.93
z = 1.27
Lets look z score table;
The area to the left of z = 0.25 is 0.5987
The area to the left of z = 1.27 is 0.8980
The probability that the z is between 0.25 and 1.27 would be 0.8980 – 0.5887 = 0.3039.
That is,
The probability that the sample mean will be between 181 and 185 is 0.3039.

Select the correct answer. For which system of inequalities is (3,-7) a solution? A. x + y < -4 3x + 2y < -5 B. x + y ≤ -4 3x + 2y < -5 C. x + y < -4 3x + 2y ≤ -5 D. x + y ≤ -4 3x + 2y ≤ -5
x + y ≤ -4 and 3x + 2y ≤ -5
======================================================
Explanation:
The given point has coordinates of x = 3 and y = -7.
Let's plug those coordinates into the first inequality of choice A.
x+y < -4
3 + (-7) < -4
-4 < -4
The last statement is false. A number cannot be smaller than itself.
Since the last inequality is false, it causes the first to be false for those x,y values. Therefore, we rule out choice A.
--------------
We'll do the same idea for the first inequality in choice B
x + y ≤ -4
3 + (-7) ≤ -4
-4 ≤ -4
This time we get a true statement at the end. The key difference is the "or equal to" portion.
Let's check the other inequality of choice B
3x + 2y < -5
3(3) + 2(-7) < -5
9 - 14 < -5
-5 < -5
We run into a similar issue as we did with choice A. We have no choice but to cross choice B off the list as well.
--------------
Choice C is eliminated for the same reason choice A was.
Choice D is the final answer because both inequalities involve "or equal to". So the -5 < -5 is now -5 ≤ -5 which is true.
It turns out that (3, -7) is on the boundary of each shaded region. It's at the intersection of the two boundary lines x+y = -4 and 3x+2y = -5.
D. x + y ≤ -4
3x + 2y ≤ -5
To see if (3, -7) satisfies both inequalities.
x + y ≤ -4:
Substitute x = 3 and y = -7 into the first inequality:
3 + (-7) ≤ -4
-4 ≤ -4
Since -4 is less than or equal to -4, the first inequality is true for the point (3, -7).
3x + 2y ≤ -5:
Substitute x = 3 and y = -7 into the second inequality:
3(3) + 2(-7) ≤ -5
9 - 14 ≤ -5
-5 ≤ -5
Since -5 is equal to -5, the second inequality is also true for the point (3, -7).

Expression:
An expression is defined as the a combination of operators, constants and variables. And it may consist of one or more operands, and zero or more operators to produce a value.
Given,
Here we have the statement "2b plus 4a minus a minus 2 plus 12b".
Now, we have to find the simplified form of this statement.
In order to find the simplified form,
First we have to convert the statement into expression form, then we get
2b plus 4a minus a minus 2 plus 12b = 2b + 4a - a - 2 + 12b
Now, we have to combine the like terms, then we get,
=> (2b + 12b) + (4a - a) - 2

NAROL is a long range hyperbolic navigation system. Suppose two NAROL transmitters are located at the
coordinates (-200, 0) and (200, 0), where unit distance on the coordinate plane is measured in miles. A
receiver is located somewhere in the first quadrant. The receiver computes that the difference in the distances
from the receiver to these transmitters is 160 miles.
What is the standard form of the hyperbola that the receiver sits on if the transmitters behave as foci of the
hyperbola?
Answer:
NORAL follows a hyperbolic path.
Equation of hyperbola; x²/6400 + y²/33600 = 1
Given,
The coordinates where the two NAROL transmitters are located = (-200, 0) and (200, 0)
The distance from receiver to these transmitters = 160 miles
We have to find the standard form of the hyperbola that the receiver sits on ;
Here,
The transmitters behave as foci of the hyperbola.
The center of hyperbola; (h, k) = (0, 0)
The distance from center to focal point,
c = 200
Square both sides
c² = 40,000
The distance from the receiver to the transmitters is given as:
2a = 160
Divide both sides by 2
a = 80
Square both sides
a² = 6400
We have:
b² = c² - a²
This gives
b² = 40000 - 6400
b² = 33600
The equation of a hyperbola is:
(x - h)²/a² + (y - k)²/b² = 1
So, we have:
(x - 0)²/6400 + (y - 0)²/33600 = 1
Therefore,
The equation of the hyperbola is:
x²/6400 + y²/33600 = 1

What is the amount of error that you will accept in the upper tail of the confidence interval?.
The amount of error that you will accept in the upper tail of the confidence interval as follows
The amount of error that will accept in the upper tail is = 13.97
Amount of error = margin of error
Margin of error = [tex]Z\frac{\alpha }{2} \frac{s}{\sqrt{n} }[/tex]
93% = confidence interval =1- [tex]\alpha[/tex]
=1-.93
=0.07
Hence [tex]\frac{\alpha }{2}[/tex] =0.035
[tex]Z\frac{\alpha }{2} or t\frac{\alpha }{2} = 1.81[/tex]
This problem represents two tail test because a two-tailed test is a method in which the critical area of a distribution is two-sided and tests whether a sample is greater or less than a range of values.
And confidence interval are always two tailed.
So margin of error = [tex]1.81x\frac{1.99}{\sqrt{40} }[/tex]
= 0.57
Upper tail C.I = x + margin of error
=13.4+0.57
=13.97
Lower tail C.I = x - margin of error

Three eighths of the 48 roses were red. (a) How many roses were red? (b) How many roses were not red? (c) What fraction of the roses were not red?
Answer:
A. 18 roses were red.
B. 30 roses were not red.
C. 5/8 were not red.
Step-by-step explanation:
In order to do this question, we first need a calculator. Then, we take three eighths and divide them on the calculator to get:
3 divided by 8 = 0.375.
Then, on the calculator again, we take the 48 roses and find the percentage of the roses that were red, by multiplying it by 0.375:
0.375 x 48 = 18.
A. 18 roses were red.
Now, for the next question, how many roses were not red. We take the 48 roses and subtract it from the roses that were red, which were 18 roses:
48 - 18 = 30.
B. 30 roses were not red.
Now, to find the fraction of the roses that weren't red. We take the 30 roses that weren't red and divide it by the total amount of 48 roses:
30 divided by 48 = 0.625.
In order to make 0.625 into a fraction, we take the higher, but lowest 100th place we can make for 0.625:
625/1,000.
Now, we simplify it:
625 divided by 5 = 125
1,000 divided by 5 = 200
Now, we have 125/200.
Simplify more:
125 divided by 5 = 25
200 divided by 5 = 40
Once more:
25 divided by 5 = 5
40 divided by 5 = 8
Our final fraction is 5/8.
C. The fraction of the roses that were not red are 5/8.
