Step-by-step explanation:
We have two rational expressions: The first rational expression has (y² - 13y +36) in the numerator and (y² + 2y - 3) in the denominator. The second rational expression has (y²-y-12) in the numerator and(y²-2y+1) in the denominator .Simplify them
We are given two rational expressions: one with (y² - 13y + 36) in the numerator and (y² + 2y – 3) in the denominator, and the other with (y² - y – 12) in the numerator and (y² - 2y + 1) in the denominator. We need to simplify these rational expressions.
Simplifying the first rational expression:
The numerator of the first expression, y² - 13y + 36, can be factored as (y – 4)(y – 9).
The denominator, y² + 2y – 3, can be factored as (y + 3)(y – 1).
Therefore, the first rational expression simplifies to (y – 4)(y – 9) / (y + 3)(y – 1).
Simplifying the second rational expression:
The numerator of the second expression, y² - y – 12, can be factored as (y – 4)(y + 3).
The denominator, y² - 2y + 1, can be factored as (y – 1)(y – 1) or (y – 1)².
Therefore, the second rational expression simplifies to (y – 4)(y + 3) / (y – 1)².
By factoring the numerator and denominator of each rational expression, we obtain the simplified forms:
First rational expression: (y – 4)(y – 9) / (y + 3)(y – 1)
Second rational expression: (y – 4)(y + 3) / (y – 1)²
These simplified expressions are in their simplest form, with no common factors in the numerator and denominator that can be further canceled.

The probability of a late departure or an early arrival P(late departure or early arrival) = 0.12 + 0.27 – 0.04
What is probability?
The probability is defined as the chances of occurence of any event from the sample.
Given: The probability of a late departure is 12 %t, the probability of early arrival is 27%.
i.e. P(late departure)=0.12
P(an early arrival)=0.27
The probability of both a late departure and an early arrival is 4 percent.
P(late departure and early arrival) =0.04
Now, using the formula the probability of the union of two dependent events A and B:-
\(\rm P(AUB)=P(A)+P(B)-P(A \cap B)\)
i.e. P(late departure or early arrival) = P(late departure)+P(an early arrival)-P(late departure and early arrival)
=0.12+0.27-0.0.04

What theorem can be used to prove that the two triangles are similar? A) SSS Similarity Theorem B) SAS Similarity Theorem C) SSA Similarity Theorem
Answer:
C) SSA Similarity Theorem
Step-by-step explanation:
The SAS Similarity Theorem asserts that if two sides of one triangle are proportionate to two sides of another triangle, and both triangles' included angles are congruent, the two triangles are similar.
in abc, angle a = 90 and an is the altitude. if ab = 20 and AC = 15, find BC, BN, NC, AN
The missing values are:
BC = 25, BN = 16, NC = 9, and AN = 12
Given:
AB = 20
AC = 15
Using the Pythagorean theorem in triangle ABC:
CB = √AC² + AB²
CB= √20² + 15²
CB= √625
CB= 25
Since, AN is altitude we have ΔNBA~ΔABC and ΔNAC~ΔABC
BN / AN = BA / CB
BN/ 20= 20/25
BN = 16
and, AN / BA = AC / CB
AN /20 = 15/ 25
AN = 12
Now, CN= CB - BN
CN = 25- 16
CN= 9
BC^2 = 20^2 + 15^2
BC^2 = 400 + 225
Since ΔANC is a right triangle so
AN = √15²-12²
AN = √81
AN = 9

At the end of 1st Quarter of 2009 the median price of a single-family home in Charleston/No. Charleston was $184,990. Single-family home prices in Charleston/No. Charleston decreased from the 1st Qtr of 2008 by 8.15%. NOTE: Depreciation means a negative value for r. (a). Estimate the median price of a single-family home in the 1st Qtr of 2008.
(b). If the median price of a single-family home falls at the same rate for the next 2 years, estimate the median price of a single-family home in the 1st Qtr of 2011.
The estimated median price of a single-family home in Charleston/No. Charleston in the 1st Quarter of 2008 is $201,048. If the median price continues to decrease at the same rate for the next two years, the estimated median price of a single-family home in the 1st Quarter of 2011 would be $144,458.
(a) To estimate the median price of a single-family home in the 1st Quarter of 2008, we need to calculate the original price before the 8.15% decrease. Let's assume the original price was P. The price after the decrease can be calculated as P - 8.15% of P, which translates to P - (0.0815 * P) = P(1 - 0.0815). Given that the end of 1st Quarter of 2009 median price was $184,990, we can set up the equation as $184,990 = P(1 - 0.0815) and solve for P. This gives us P ≈ $201,048 as the estimated median price of a single-family home in the 1st Quarter of 2008.
(b) If the median price of a single-family home falls at the same rate for the next two years, we can calculate the price for the 1st Quarter of 2011 using the estimated median price from the 1st Quarter of 2009. Starting with the median price of $184,990, we need to apply an 8.15% decrease for two consecutive years. After the first year, the price would be $184,990 - (0.0815 * $184,990) = $169,805.95. Applying the same percentage decrease for the second year, the price would be $169,805.95 - (0.0815 * $169,805.95) = $156,012.32. Therefore, the estimated median price of a single-family home in the 1st Quarter of 2011 would be approximately $144,458.

If we draw 1,000 samples of size 100 from a population and compute the mean of each sample, the variability of the distribution of sample means will tend to be _________ the variability of the raw scores in any one sample.
A) smaller than
B) equal to
C) greater than
D) cannot be determined from the information givenv
The correct answer is A) smaller than.
The statement refers to the concept of the Central Limit Theorem (CLT). According to the CLT, when random samples are drawn from a population, the distribution of sample means will tend to follow a normal distribution, regardless of the shape of the population distribution, given that the sample size is sufficiently large. This means that as the number of samples increases, the variability of the distribution of sample means will decrease.
In this case, drawing 1,000 samples of size 100 from a population and computing the mean of each sample implies that we have a large number of sample means. Due to the CLT, the distribution of these sample means will have less variability (smaller standard deviation) compared to the variability of the raw scores in any one sample. Thus, the variability of the distribution of sample means will tend to be smaller than the variability of the raw scores in any one sample.

Find the volume of the solid obtained by rotating the region bounded by x=7 y^2, \ y = 1, \ x = 0, about the y-axis.
The volume of the solid obtained by rotating the region bounded by \(x=7y^2\), \(y=1\), \(x=0\) about the y-axis can be found using the method of cylindrical shells.
To find the volume of the solid obtained by rotating the region bounded by \(x=7y^2\), \(y=1\), and \(x=0\) about the y-axis, we can use the method of cylindrical shells.
The cylindrical shells are formed by considering thin vertical strips of the region and rotating them around the y-axis. Each strip has a height of \(7y^2\) and a radius of \(y\) (since the distance from the y-axis to the strip is equal to the value of y).
To calculate the volume, we integrate the product of the circumference of each shell (which is \(2\pi y\)) and its height (\(7y^2\)) with respect to y over the interval from 0 to 1. The integral expression is:
\[V = \int_{0}^{1} 2\pi y \cdot 7y^2 \, dy\]
Simplifying the integral and evaluating it gives us the volume of the solid.

a. The linear equation that models the temperature T as a function of the number of chirps per minute N is: T(N) = (1/9)N + 60
b. If the crickets are chirping at 155 chirps per minute, the estimated temperature is approximately 77.22 degrees Fahrenheit.
How to calculate the valuea. Let's first find the slope of the line using the formula:
slope (m) = (y2 - y1) / (x2 - x1)
where (x1, y1) = (117, 73) and (x2, y2) = (180, 80).
slope = (80 - 73) / (180 - 117)
= 7 / 63
= 1/9
Now, let's use the point-slope form of a linear equation:
y - y1 = m(x - x1)
Using the point (117, 73):
T - 73 = (1/9)(N - 117)
Simplifying the equation:
T - 73 = (1/9)N - (1/9)117
T - 73 = (1/9)N - 13
Now, let's rearrange the equation to solve for T:
T = (1/9)N - 13 + 73
T = (1/9)N + 60
Therefore, the linear equation that models the temperature T as a function of the number of chirps per minute N is: T(N) = (1/9)N + 60
(b) If the crickets are chirping at 155 chirps per minute, we can estimate the temperature T using the linear equation we derived.
T(N) = (1/9)N + 60
Substituting N = 155:
T(155) = (1/9)(155) + 60
T(155) = 17.22 + 60
T(155) ≈ 77.22
Therefore, if the crickets are chirping at 155 chirps per minute, the estimated temperature is approximately 77.22 degrees Fahrenheit.

* PLEASE HURRY* Here is the graph for one equation in a system of equations:
(0,4) (5.5,0)
Write an equation for the system so it has infinitely many solutions.
Write a second equation whose graph goes through (0,1) so the system has no solutions.
Write a third equation whose graph goes through (0,2) so the system has one solution at (4,1).
Answer:
1) The equation that has infinitely many solution is y = -8/11·x + 4
2) The equation of the graph that has no solution is y = -8/11·x + 1
3) The equation of the line that has only one solution is y = -1/4·x + 2
Step-by-step explanation:
1) The points on the graph are;
(0, 4), and (5.5, 0)
The slope of the line defined by the given two points, we have;
(0 - 4)/(5.5 - 0) = -40/55 = -8/11
The equation of the straight line graph in point and slope form, we have;
y - 4 = -8/11 × (x - 0)
y - 4 = -8/11·x
For the equation for the system that has infinitely many solution, we have;
y = -8/11·x + 4
2) For the equation whose graph foes through the point (0, 1) and the system has no solution, we have;
An equation that has no solution with the equation y = -8/11·x + 4, is parallel to y = -8/11·x + 4, and therefore, the slope are equal
Therefore, the equation whose graph foes through the point (0, 1) and the system has no solution, in point and slope form is given as follows;
y - 1 = -8/11 × (x - 0)
y - 1 = -8/11·x
The equation of the graph that has no solution is therefore;
y = -8/11·x + 1
3) For the equation of the graph that goes through the point (0, 2), and has a common solution with the system at (4, 1), we have;
The slope of the graph is (1 - 2)/(4 - 0) = -1/4
The equation of the line that has only one solution with the system in point and slope form is given as follows;
y - 2 = -1/4×(x - 0)
y - 2 = -1/4·x
The equation of the line that has only one solution in standard form is therefore;
y = -1/4·x + 2

Which statement is true about the value of |-5|? It is the distance that -5 is form 0 on the number line. It is the distance that -5 from 5 on the number line. It is less than 5. It is greater than 5.
Answer: It is the distance that -5 is form 0 on the number line
Step-by-step explanation:
We can define the absolute value of any number:
IxI as:
"The distance between the point x and the origin in the coordinate axis"
If we are in one dimension, x is just a value, and the coordinate axis will be a number line.
Then we could rewrite this as:
"is the distance between the value x and the 0 in the number line"
So:
IxI = x if x > 0
IxI = -x if x < 0.
Then:
I -5 I
Is the distance between the number -5, and the 0 in the number line, and this is:
I - 5 I = 5.
The correct option is:
"It is the distance that -5 is form 0 on the number line"
Answer:
Answer: It is the distance that -5 is form 0 on the number line

Three of five baseketball players scored more than 10 points. What percent of the players scored more than 10 points?
60 percent of the players scored more than 10 points if three of the five basketball players scored more than 10 points.
What is the percentage?
It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
Three of the five basketball players scored more than 10 points.
Total number of basketball players = 5
The number of players who scored more than 10 points = 3
In fraction:
= 3/5
= 0.6
To convert the above fraction into the percentage multiply it by 100:
= 0.6x100
The percent of the players scored more than 10 points = 60%
Thus, 60 percent of the players scored more than 10 points if three of the five basketball players scored more than 10 points.
