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

Customers arrive at a movie theater at the advertised movie time only to find that they have to sit through several previews and prepreview ads before the movie starts. Many complain that the time devoted to previews is too long. A preliminary sample conducted by the wall street journal showed that the standard deviation of the amount of time devoted to previews was 4 minutes. Use that as a planning value for the standard deviation in answering the following questions. Round your answer to next whole number. A. If we want to estimate the population mean time for previews at movie theaters with a margin of error of seconds, what sample size should be used? assume confidence. B. If we want to estimate the population mean time for previews at movie theaters with a margin of error of minute, what sample size should be used? assume confidence.
If we want to estimate the population mean time for previews at movie theaters with a margin of error of minute, then 56 sample size should be used and if we want to estimate the population mean time for previews at movie theaters with a margin of error of minute, then 22 sample size should be used.
In the given question,
A preliminary sample conducted by the wall street journal showed that the standard deviation of the amount of time devoted to previews was 4 minutes.
(a) We have to estimate the population mean time for previews at movie theaters with a margin of error of seconds, what sample size should be used.
Assuming the confidence interval 98% and margin error of 75 seconds.
We can write 98% as 0.98.
So the value of z at 98% confidence interval using the standard table of z is 2.326.
Standard Deviation= 4 minutes
Converting minutes in seconds so,
Standard Deviation= 4*60
Standard Deviation= 240
Margin of error is 75 seconds.
So the sample size = (Value of z * Standard Deviation)/Margin Error
Sample Size = ((2.326*240)/75)^2
Sample Size = (558.24/75)^2
Sample Size = (7.4432)^2
Sample Size = 55.401
Approx value of Sample Size = 56
Hence, if we want to estimate the population mean time for previews at movie theaters with a margin of error of 75 seconds, then 56 sample size should be used.
(b) We have to estimate if we want to estimate the population mean time for previews at movie theaters with a margin of error of minute, what sample size should be used.
The given margin of error is 75 seconds.
Now converting the error in minute by dividing 60.
Now the margin of error = 75/60=5/6 minute
Standard Deviation= 4 minutes
The confidence interval 98% and margin error of 75 seconds.
We can write 98% as 0.98.
So the sample size = (Value of z * Standard Deviation)/Margin Error
sample size = {(0.98*4)/(5/6)}^2
sample size = {6(0.98*4)/5}^2
sample size = (6*3.92/5)^2
sample size = (23.52/5)^2
sample size = (4.704)^2
sample size = 22.13
Approx value of Sample Size = 22
Hence, if we want to estimate the population mean time for previews at movie theaters with a margin of error of minute, then 22 sample size should be used.

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).

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.

Look at the key.
Left side of the equal sign:
A grey rectangle means x.
There are 3 grey rectangles on the left side, so that is 3x.
A white square means -1.
There are 4 white squares on the left side, so that means -4.
Altogether, the left side is 3x - 4.
Right side of the equal sign:
A black square means 1.
There are 6 black squares, so that means 6.
A white rectangle means -x.
There are 2 white rectangles, so that means -2x.
Altogether, the right side is 6 - 2x.

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.
