The given equation is not exact. To determine whether the equation is exact or not, we need to check if the partial derivatives of the coefficients with respect to x and y are equal.

Let's calculate these partial derivatives:

∂(y/x+9x)/∂y = 1/x

∂(ln(x)−2)/∂x = 1/x

The partial derivatives are not equal, which means the equation is not exact. Therefore, we cannot directly find a solution using the method of exact equations.

To proceed further, we can check if the equation is an integrating factor equation by calculating the integrating factor (IF). The integrating factor is given by:

IF = e^∫(∂Q/∂x - ∂P/∂y) dy

Here, P = y/x+9x and Q = ln(x)−2. Calculating the difference of partial derivatives:

∂Q/∂x - ∂P/∂y = 1/x - 1/x = 0

Since the difference is zero, the integrating factor is 1, indicating that no integrating factor is needed.

As a result, since the equation is not exact and no integrating factor is required, we cannot find a solution to the given equation. Hence, the solution is "NS" (No Solution).

The frequency of a given allele, g, in the population is defined as the ratio of the number of copies of that allele to the total number of copies of all alleles.

The proportion of homozygous dominant (GG), heterozygous (Gg), and homozygous recessive (gg) individuals in a population can be calculated using the following equations:
GG = p2
Gg = 2pq
gg = q2
Where p is the frequency of the G allele, q is the frequency of the g allele, and p + q = 1.Since g is recessive, the frequency of white (gg) moths in the population is q2. The frequency of the g allele can be calculated using the following formula:
p = 1 - q

Given that the population was in Hardy-Weinberg equilibrium for the g locus, we can assume that the allele frequencies remained constant over time.

As a result, we can use the frequency of the g allele in 1980 to estimate its frequency in 1962. Using the frequency of the g allele in 1980 as p, we can use the Hardy-Weinberg equations to determine the frequency of the g allele in 1962:
p = 0.54q = 0.46
Using these frequencies, we can calculate the proportion of white moths in the population in 1962:
q2 = 0.46 x 0.46 = 0.2116 = 21.16%
Therefore, the percentage of moths in the natural population that was white in 1962 was approximately 21.16%.Option E is correct (64%).

To create the playoff schedule for the Montréal Centre-Island Football League championship tournament, we need to rank the teams in order of power. To do this, we can analyze the results of the regular season games and create a dominance-directed graph, an adjacency matrix, and perform some calculations.

1. Dominance-Directed Graph:
Let's create a diagram of the dominance-directed graph using the information provided:

```
                     (1) Colts
                   /       |     \
           (2) Eagles   (3) Giants
              /              |
        (5) Saints    (4) Packers
```

2. Adjacency Matrix:
Now, let's create an adjacency matrix based on the dominance-directed graph. This matrix will help us visualize the relationships between the teams:

```
         | Colts | Eagles | Giants | Packers | Saints |
-------------------------------------------------------
Colts     |   0   |   1    |   0    |    1    |   1    |
Eagles    |   0   |   0    |   1    |    1    |   0    |
Giants    |   0   |   0    |   0    |    1    |   1    |
Packers   |   0   |   0    |   0    |    0    |   1    |
Saints    |   0   |   1    |   0    |    0    |   0    |
```

In the adjacency matrix, a "1" indicates that a team has defeated another team, while a "0" indicates no victory.

3. Calculations:
Based on the adjacency matrix, we can calculate the power score for each team. The power score is the sum of each team's victories over other teams.

- Colts: 1 victory (against Packers)
- Eagles: 2 victories (against Colts and Giants)
- Giants: 2 victories (against Colts and Saints)
- Packers: 1 victory (against Saints)
- Saints: 1 victory (against Eagles)

4. Ranking:
Now, let's list the teams in order of power:

1. Eagles (2 victories)
2. Giants (2 victories)
3. Colts (1 victory)
4. Packers (1 victory)
5. Saints (1 victory)

The Eagles and Giants are tied for the first position, as they both have 2 victories. Colts, Packers, and Saints each have 1 victory.

To summarize:
Produce a listing of the teams in order of power and indicate whether any teams are tied. Be sure to include all details of the process, including:

slope = 1/2,  y intercept = 3

==============================================================

Work Shown:

Pick any two points you want on the line.

I'll pick the two points (0,3) which is the y intercept and also the point (2,4).

------

Find the slope of the line through (x1,y1) = (0,3) and (x2,y2) = (2,4)

m = (y2 - y1)/(x2 - x1)

m = (4 - 3)/(2 - 0)

m = 1/2 is the slope

slope = rise/run = 1/2

rise/run = 1/2 means rise = 1 and run = 2.

This means we go up 1 unit each time we move to the right 2 units.

-----

Since the slope is m = 1/2 and the y intercept is b = 3, we can say

y = mx+b

y = (1/2)x+3

this is the same as y = 0.5x+3 since 1/2 = 0.5

Based on the survey results, a typical parent would spend around $44 on their child's birthday gift, with a margin of error of approximately $2.9 at a 99% confidence level.

To estimate how much a typical parent would spend on their child's birthday gift, we use the sample mean and standard deviation as estimates of the population parameters. The sample mean of $44 serves as the point estimate for the population mean.

To determine the margin of error, we use the standard error, which is the standard deviation divided by the square root of the sample size. In this case, the standard error is approximately $2.5 (standard deviation of $10 divided by the square root of 20). Multiplying the standard error by the critical value corresponding to a 99% confidence level (z-value of 2.58 for a large sample size) gives us the margin of error.

Therefore, the typical amount spent on a child's birthday gift is estimated to be $44, with a margin of error of approximately $2.9. This means that we can be 99% confident that the true mean amount spent by parents falls within the range of $41.1 to $46.9.

Answer:

Below

Step-by-step explanation:

The line L has the following equation:

● 2x - 3y = 5

Add -2x to both sides

● 2x - 3y -2x = 5 - 2x

● -3y = 5 - 2x

Multiply both sides by -1

● (-1) × -3y = (-1) × (5-2x)

● 3y = 2x - 5

Divide both sides by 3

● 3y/3 = (2x - 5)/3

● y = (2/3)x - 5/3

The line M is perpendicular to L

So the product of their slopes is -1

Let m be the slope of M

● m × (2/3) = -1

● m = -1 × (3/2)

● m = -3/2

So the equation of M is:

● y = (-3/2)x + b

b is the y-intercept

M passes through (2, -10)

Replace by the coordinates of this point

● -10 = (-3/2)×2 + b

● -10 = -3 + b

● b = -10 + 3

● b = -7

The equation of M is

● y = (-3/2)x -7

If you can choose one item from a group of m items and a second item from a group of n items, then the total number of two-item choices is m x n.

The total number of two-item choices that can be made when one item is chosen from a group of m items and a second item is chosen from a group of n items is given by the product of the number of choices for the first item and the number of choices for the second item.

The number of choices for the first item is m since there are m items to choose from in the first group, and the number of choices for the second item is n since there are n items to choose from in the second group.

Therefore, the total number of two-item choices is given by m x n. For example, if there are 4 items in the first group and 5 items in the second group, then the total number of two-item choices is 4 x 5 = 20.

This formula for finding the total number of two-item choices can be extended to larger groups of items as well. For instance, if there are three groups of items with sizes m, n, and p, then the total number of three-item choices is given by m x n x p.

Step-by-step explanation:

If CD and MB are parallel, triangle CDE is similar to triangle MBE.

In similar triangles, corresponding sides are always in the same ratio.

\(\implies \sf CD:MB=DE:BE=EC:EM\)

From inspection of the given diagram, EM is approximately 0.35 times the length of EC.  Therefore, let EC = 10 and EM = 3.5.

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Therefore, let CD = 7 and let DE = 12.

Substitute these values into the created ratio equation:

\(\implies \sf 7:MB=12:BE=10:3.5\)

\(\implies \sf \dfrac{7}{MB}=\dfrac{12}{BE}=\dfrac{10}{3.5}\)

Calculate BE:

\(\implies \sf \dfrac{12}{BE}=\dfrac{10}{3.5}\)

\(\implies \sf \dfrac{12 \cdot 3.5}{10}=BE\)

\(\implies \sf BE=4.2\)

Calculate MB:

\(\implies \sf \dfrac{7}{MB}=\dfrac{10}{3.5}\)

\(\implies \sf \dfrac{7 \cdot 3.5}{10}=MB\)

\(\implies \sf MB=2.45\)

Therefore:

\(\implies \sf CM=EC-EM\)

\(\implies \sf CM=10-3.5\)

\(\implies \sf CM=6.5\)

\(\implies \sf DB=DE-BE\)

\(\implies \sf DB=12-4.2\)

Barbara wrote an equation, 1.25x + 1.49, to find the number of bottles (x) she needs to sell in order to earn $100.

The equation 1.25x + 1.49 represents the total earnings Barbara would make by selling x bottles of water at $1.25 per bottle and x bottles of iced tea at $1.49 per bottle. The term 1.25x represents the earnings from selling water, and 1.49 represents the earnings from selling iced tea.

To find the number of bottles (x) Barbara needs to sell to earn $100, we set the equation equal to $100 and solve for x:

1.25x + 1.49 = 100

By rearranging the equation and isolating the variable x, we can solve for x. This equation can be solved using algebraic techniques such as combining like terms, subtracting 1.49 from both sides, and dividing by 1.25.

Once we determine the value of x, we will know the number of bottles Barbara needs to sell in order to earn $100.

Which is linear equation of two variables.

A linear equation is an algebraic equation of the form y = mx + b , with only one constant and one first-order (linear) term, m is the slope and b is the y-intercept.

We have given that,

the ratio of y and x is y : x = 3 : 7

So the ratio of x and y can be expressed as ,

x : y = 7 : 3 ( reverse order)

So let's consider two points as

(x₁, y₁)=(7 , 3) and (x₂, y₂) = (14 , 6)

The equation of the line passing through these points will be,

( y - y₁ )/ (y₂ - y₁) = (x - x₁)/(x₂ - x₁)

=> (y - 3)/(6-3) = (x - 7)/(14 - 7)

=> (y - 3)/3 = (x - 7)/7

=> 7(y - 3) = 3( x - 7)

=> 7y - 21 = 3x - 21

The equation of a circle with radius r and center (h,k) is \((x - h)^2 + (y - k)^2 = r^2.\)

In this case, the radius is r = 56 and the center is (h,k) = (9,0).

Therefore, the equation of the circle can be calculated as follows: \((x - 9)^2 + (y - 0)^2 = 562.\)

Expanding the equation, we can calculate \((x^2 - 18x + 81) + (y^2 - 0) = 3136.\)

Answer:

C. Yes, there is an outlier at 110. This means that one person's age was 110, which is 25 years older than the next closest age.

Step-by-step explanation:

An outlier is a data point that sticks out like a sore thumb. It's so different from the rest of the data that it makes you wonder if it's a mistake or a miracle. One way to spot an outlier is to use the 1.5IQR rule, where IQR stands for interquartile range. The interquartile range is the gap between the third quartile (Q3) and the first quartile (Q1) of the data. The 1.5IQR rule says that any data point that is more than 1.5*IQR above Q3 or below Q1 is an outlier.

In this case, the first quartile (Q1) is 75, the third quartile (Q3) is 85, and the interquartile range (IQR) is 10. So, any data point that is more than 1.5*10 = 15 above 85 or below 75 is an outlier. The only data point that does this is 110, which is 25 above 85. That means 110 is an outlier.

What does this outlier mean in this situation? It means that one person who came to the senior center that afternoon was way older than the rest of the folks. The average age of the visitors was not changed by this outlier, since it was just one out of 12 data points. But, the outlier does mess up the range and the standard deviation of the data, making them bigger than they would be without the outlier.
