Put the following equation of a line into lope-intercept form,implifying all fraction 8x12y=108
The slope of the line from the equation is 2/3.
The line:
A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions.
The formula of a line:
y = mx + c
m = slope
c = y-intercept
Here we are provided with the equation:
8x - 12y = 108
12y = 8x - 108
y = 2/3x - 9
So by equating we get the slope:
m = 2/3
Therefore the slope is 2/3.

Describe each of the following transformation that maps the figures described below. Be specific by naming lines of reflection, centers of rotation and degrees of rotation, distance and direction of translations, and centers of dilation with a scale factor. Determine if the transformation is a rigid transformation or a similarity transformation. Explain all reasoning.
The image is then dilated by a scale factor of half with a center of dilation of (1, 2); Preimage (8, 4), (4, -4), and (1, 2) → Image (1, 2), (2.5, -1), and (4.5, 3).
What is rigid transformation?A rigid transformation (also called an isometry) is a transformation of the plane that preserves length. In a rigid transformation the pre-image and image are congruent (have the same shape and sizes).
The coordinates of the vertices of the preimage will be;
(5, 10), (2, 4), (9, 2)
The coordinates of the vertices of the image will be;
(-9, -2), (-2, -4), (-5, -10)
This is equivalent to a reflection about the origin, and a rotation of 180° clockwise or anticlockwise about the origin.
Part B: Figure 2 to Figure 5
The coordinate points of figure 2 will be;
(-9, 2), (-5, 10), and (-2, 4)
The coordinate points of figure 5 will be;
(1, 2), (2.5, -1), and (4.5, 3)
The lengths of the sides of figure 2 will be;
√((10 - 2)² + ((-5) - (-9))²) = 4·√5
√((10 - 4)² + ((-5) - (-2))²) = 3·√5
√((2 - 4)² + ((-9) - (-2))²) = √53
The lengths of the sides of figure 5 will be;
√(((-1) - 2)² + (2.5 - 1)²) = (3·√5)/2
√((4.5 - 2.5)² + (3 - (-1))²) = 2·√5
√((4.5 - 1)² + (3 - 2)²) = (√53)/2
Thus, Figure 5 is Figure 2 dilated by a scale factor of 1/2(half )
Therefore, the given sides of Figure 2 and Figure 5 are rotated by 180°
1) The rotation of figure 2 by 180° about the origin to get;
(-9, 2), (-5, 10), and (-2, 4) → (9, -2), (5, -10), and (2, -4)
2) The image is translated left by 1 blocks and up by 6 blocks as;
(9, -2), (5, -10), and (2, -4) → (8, 4), (4, -4), and (1, 2)
3) The image is then dilated by a scale factor of half with a center of dilation of (1, 2);
Preimage (8, 4), (4, -4), and (1, 2) → Image (1, 2), (2.5, -1), and (4.5, 3).

0.86 of the exam scores are between 68 and 77.99 points
Since the set of computer science exam scores are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x-μ)/σ
Where
X = computer science exam scores.
μ = mean score
σ = standard deviation
From the information given,
μ = 71.33 points
σ = 333 points
We want to find the proportion of the exam scores are between 68 and 77.99 points. It is expressed as
P(68 < x ≤ 77.99)
For x = 68,
z = (68 - 71.331)/333 = - 0.01
Looking at the normal distribution table, the probability corresponding to the z score is -0.01
For x = 68,
z = (77.99 - 71.33)/333 = 0.25
Looking at the normal distribution table, the probability corresponding to the z score is 0.25

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).

Step-by-step explanation:
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.

If the rate of change is constant, the volume of the water in the pond by the year 2030 will be 147 gallons.
Define volume.
Any three-dimensional solid's volume is just the amount of space it takes up. It can be any shape like a cube, cuboid, cone, cylinder, etc. Various forms have various volumes. We have studied the several solids and forms that are specified in three dimensions, such as cubes, cuboids, cylinders, cones, etc., in 3D geometry. The SI unit of volume is cubic units.
Solution Explained:
Based on the conditions given in the question, we formulate as follows
(612 X (2024 - 2020) + (612 - 798) X (2030 - 2020) / (2024-2020)
= (612 X 4 - 186 X 10) / 4
= (2448 - 1860) / 4
= 588 / 4
= 147
Therefore, by 2030 the volume of the water in the pond will be 147 gallons.
