Answer:

AB = 19.6 cm

Step-by-step explanation:

Let AB be represented by c. Applying the cosine rule, we have;

\(c^{2}\) = \(a ^{2}\) + \(b^{2}\) - 2ab Cos C

  = \(12^{2}\) + \(18^{2}\) - 2(12 x 18) Cos \(79^{o}\)

  = 144 + 324 -432(0.19081)

  = 468 - 82.4299

\(c^{2}\) = 385.5701

c = \(\sqrt{385.5701}\)

c = 19.6359

The side AB of the given triangle is 19.6 centimetres.

The graph drawn is the graph of a square root function. A similar example is drawn below for the function:

We can thus deduce that the graph is a square root function

From the graph, the x-intercept is given by the point where the graph crosses the x-axis (at the point, y equals zero). The graph crosses the x-axis at x equals 8. It is given as shown below:

Answer:

13 units

Step-by-step explanation:

Here we need to use the distance formula.

Hence we get that,

AB =  \(\sqrt{(-8-4)^2 + (4-(-1))^2}\)

AB =  \(\sqrt{(-12)^2 + 5^2}\)

AB =  \(\sqrt{144 + 25}\)

AB =  \(\sqrt{169}\)

AB =  13

The distance between point A(-8,4) and B(4,-1) is 13 units.

The distance between two points of the xy-plane can be found using the distance formula. The distance formula is:

√[(x₂ - x₁)² + (y₂ - y₁)²].

Now the given points are,

A(-8,4) and B(4,-1)

Therefore we have,

x₁ = -8

y₁ = 4

x₂ = 4

y₂ = -1

Now distance between A(1,4) and B(-3,3.5) = √[(x₂ - x₁)² + (y₂ - y₁)²]

= √[(4 - (-8))² + (-1 - 4)²]

= √[(4 + 8)² + (-5)²]

= √(12² +25)

= √(144 +25)

= √169

= 13 units

Thus, the distance between points A(-8,4) and B(4,-1) is 13 units.

50 quarts of sparking water and 25 quarts of grape juice are needed for 75 quarts of punch.

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.

Given that a punch recipe calls for 1(¹/₂) quart of sparkling water and 3/4 of a quart of grape juice.

The ratio of sparkling water to grape juice is,

1(¹/₂) : (3/4 quarts) = (3/2) : (3/4) =  2 : 1

The amount sparkling water in the total volume is 2 : (2+1) = 2/3 of the total volume. For a volume of 100 quarts, the sparkling water content is

2/3 · 75quarts = 50 quarts

Then the grape juice content is,

1/3 · 75 quarts = 25 quarts

Therefore, 50 quarts of sparking water and 25 quarts of grape juice are needed for 75 quarts of punch.

Performing a Chi-Square test is a statistical tool used to determine if there is a significant difference between observed and expected data. The test helps to analyze categorical data by comparing observed frequencies to the expected frequencies. The p-value in a Chi-Square test refers to the probability of obtaining the observed results by chance alone.

If a p-value lower than 0.01 is obtained in a Chi-Square test, it means that the results are statistically significant. In other words, there is strong evidence to reject the null hypothesis, which states that there is no significant difference between the observed and expected data. This means that the observed data is not due to chance alone, but rather to some other factor or factors.

The mean, or average, is not directly related to the Chi-Square test or the p-value. The Chi-Square test is specifically used to determine the significance of the observed data. However, the mean can be used as a measure of central tendency for continuous data, but it is not applicable to categorical data.

In conclusion, obtaining a p-value lower than 0.01 in a Chi-Square test means that there is strong evidence to reject the null hypothesis, and that the observed data is statistically significant.

Answer:

C

Step-by-step explanation:

The diagonal matrix D using the eigenvalues on the diagonal in the same order as the orthonormal basis vectors. Thus, D = diag(2, 2, 3)

(a) If A^2 = 6, we can determine the diagonal matrix equivalent to A by considering its eigenvalues and eigenvectors.

The characteristic polynomial of A is given as (t - 2)^2(t - 3). This means that the eigenvalues of A are 2 (with multiplicity 2) and 3.

To find the eigenvectors corresponding to each eigenvalue, we solve the system of equations (A - λI)v = 0, where λ represents each eigenvalue.

For λ = 2:

(A - 2I)v = 0

|0 0 0| |x| |0|

|0 0 0| |y| = |0|

|0 0 1| |z| |0|

This implies that z = 0, and x and y can be any real numbers. An eigenvector corresponding to λ = 2 is v1 = (x, y, 0), where x and y are real numbers.

For λ = 3:

(A - 3I)v = 0

|-1 0 0| |x| |0|

|0 -1 0| |y| = |0|

|0 0 0| |z| |0|

This implies that x = 0, y = 0, and z can be any real number. An eigenvector corresponding to λ = 3 is v2 = (0, 0, z), where z is a real number.

Now, we need to normalize the eigenvectors to obtain an orthonormal basis.

A possible orthonormal basis for A is {v1/||v1||, v2/||v2||}, where ||v1|| and ||v2|| are the norms of the respective eigenvectors.

Finally, we can construct the diagonal matrix D using the eigenvalues on the diagonal in the same order as the orthonormal basis vectors. Thus, D = diag(2, 2, 3).

(b) Without the specific value for A^2, we cannot determine the diagonal matrix equivalent to A or find an orthonormal basis for diagonalization. The diagonal matrix would depend on the specific eigenvalues and eigenvectors of A^2. Therefore, we do not have enough information to provide the diagonal matrix or the orthonormal basis in this case.

If there are approximately 2,000,000 described eukaryotic species and approximately 50% are insects, then the number of described insect species is 2,000,000 * 0.5 = 1,000,000.

The Nature Conservancy identified 400 species of beetles, of which 100 had been previously described. This means that they discovered 400 - 100 = 300 new beetle species.

Assuming that the proportion of new beetle species to total insect species is the same as the proportion of described beetle species to described insect species, we can set up the following proportion:

300 / x = 100 / 1,000,000

where x is the total number of insect species.

Solving for x, we get:

x = (300 * 1,000,000) / 100

x = 3,000,000

Therefore, the 2020 data suggests that there are a total of 3,000,000 insect species.

To determine which payment plan the real estate investor would prefer, we need to compare the present value of each payment option. Assuming a discount rate of 0%, meaning no time value of money is considered, we can directly compare the payment amounts.

1. Payment of $2,000 at the first of each month: This results in a total payment of $24,000 over the 12-month lease.

2. Upfront payment of $24,000: This option requires paying the full amount at the beginning of the lease.

3. Payment of $2,000 at the end of each month: Similar to option 1, this results in a total payment of $24,000 over the 12-month lease.

4. Upfront payment of $12,000 and $12,000 half-way through the lease: This option requires paying $12,000 at the beginning of the lease and another $12,000 halfway through the lease.

Since all the payment options have a total cost of $24,000, the real estate investor would likely prefer the payment plan that offers more flexibility or matches their cash flow preferences. Options 1 and 3 provide the investor with the option to pay monthly, while options 2 and 4 require a larger upfront payment. The choice would depend on the investor's financial situation and preferences.

Answer: \(12\pi\)

Step-by-step explanation:

The formula for area of a circle is \(\pi r^2=A\)

The formula for circumference of a circle is \(2r\pi=C\)

Where r is the radius

A is area

C is circumference

Knowing this we can sub our values in and solve for r in the formula for area

Divide both sides by \(\pi\) to isolate r

\(\pi r^2=A\\\pi r^2=36\pi \\\frac{\pi r^2}{\pi } =\frac{36\pi }{\pi } \\r^2=36\)

Take the square root of both sides

\(r^2=36\\\sqrt{r^2} =\sqrt{36} \\r=6\)

Now sub the value of r into the formula for circumference

\(2r\pi =C\\2(6)\pi =C\\12\pi\)

$4,420.00 ≤ t ≤ $4,834.38

Step-by-step explanation:

Since yearly employee wages range from 32 to 35%, lets calculate what those percentages are in dollars:

32%:  ($165,750)*(0.32) = $53,040/year

35%:  ($165,750)*(0.35) = $58,012.5/year

To find the average monthly budget, divide the yearly budget by 12 months

32%:   $53,040/year*(1 year/12 months) = $4,420/month

35%:  ($58,012.5/year*(1 year/12 months) = $4,834.4/month

t ranges from $4,420/month to $4,834.4/month

$4,420.00 ≤ t  ≤$4,834.38

Answer:

\((x,y) = (65^\circ, 50^\circ)\)

Step-by-step explanation:

Let all values denote degrees.

By the exterior angle theorem, \(x + y = 115\). Moreover, because we are dealing with an isoceles triangle, \(y = 180 - 2x\). Substituting this into the former equation gives \(180-x=115\) and as such \(x=65\). Because \(x + y = 115\) we now also know that \(y=50\).

Answer:

x° = 65° & y° = 50°.

Step-by-step explanation:

115° = x° + y° ( exterior angle property )

Let's name that angle to the right of 115° as 'a'.

a = 180 - 115 = 65°. (linear pair)

Now we know that the triangle is an isosceles triangle. (given)

So this makes x° also as 65° (equal sides make equal angles).

This leaves behind y°.

y° = 180 - (65+65) = 50°.

So, x° = 65° & y° = 50°.

Chelsea made a mistake in simplifying the equation 3(x-3). To find the solution to 4x-5=2(3(x-3)), we first simplify the expression inside the parentheses.

Now, to isolate the variable x, we need to move the terms with x to one side of the equation. Let's subtract 4x from both sides, which gives us -5-4x=6x-18-4x. Simplifying this, we get -5-4x=2x-18.

Next, let's move the constant terms to the other side. Adding 18 to both sides, we get -5-4x+18=2x-18+18. Simplifying this, we get -4x+13=2x.

Chelsea made a mistake when subtracting the variable term from both sides. By identifying this error and correctly following the steps, we find that the solution to the equation 4x - 5 = 2 3(x - 3) is x = -7.

Chelsea made a mistake in her work when finding the solution to the equation 4x - 5 = 2 3(x - 3). To determine where she went wrong, let's analyze her steps.

Step 1: Distribute 3 to (x - 3): 4x - 5 = 2 3x - 6.
Step 2: Combine like terms: 4x - 5 = 6x - 12.
Step 3: Move the variables to one side and the constants to the other side. Chelsea may have mistakenly subtracted 4x from both sides instead of 6x. This would result in: -5 = 2x - 12.
Step 4: Solve for x. Chelsea may have then incorrectly added 12 to both sides instead of adding 5, leading to: 7 = 2x.
Step 5: Divide both sides by 2: x = 7/2.

Upon reviewing her work, Chelsea should have subtracted 6x from both sides in Step 3, not 4x. This would have resulted in the equation 2x - 5 = -12. Correctly following the steps would lead to the correct solution: x = -7.

Therefore, Chelsea made a mistake when subtracting the variable term from both sides. By identifying this error and correctly following the steps, we find that the solution to the equation 4x - 5 = 2 3(x - 3) is x = -7.

The short-run supply curve shows the quantity of output a firm is willing to supply at different market prices in the short run. It is typically upward sloping, meaning that as the price of the product increases, the firm is willing to produce and supply more units. This is because higher prices will allow the firm to cover its variable costs and potentially earn a profit.

When used in conjunction with the average variable cost (AVC) curve, the supply curve can give a firm valuable information about its profits. The AVC curve represents the average variable cost per unit of output, which includes the costs that vary with the level of production (such as labor and materials).

If the market price is above the AVC curve, the firm is covering all of its variable costs and may earn a profit. If the market price is below the AVC curve but still above the average total cost (ATC) curve, the firm is not covering all of its costs but is still producing because it is covering its variable costs. If the market price falls below the ATC curve, the firm is not covering all of its costs and is likely to shut down production in the short run.

Therefore, the supply curve in conjunction with the AVC curve allows a firm to determine whether it should produce and supply output in the short run based on the prevailing market price. If the market price is high enough to cover variable costs and potentially earn a profit, the firm will continue to produce. However, if the market price falls below the AVC curve, the firm will likely reduce or cease production to minimize losses.

30+4=34 68 is double of 34 so it is logical to double the ratio to get 8:60. So that means there should be 8 convertibles.

If I found the average value using the median, the answer would be 4.5.

In this set of data, the anomaly is 23 as it is much higher than the other numbers.

The median is more accurate because it find the more ‘central’ number and is not affected as greatly with anomalies whereas the mean is affected greatly with anomalies as it raises the value significantly.

Therefore, the median is better to work out the average in this set of data.
