Triangle KVM is similar to triangle BVG because angle M = angle G = 90° and angle V is common to both triangles.

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio.

For two triangles to be similar, the corresponding angles must be congruent i.e equal.. Also the ratio of the corresponding sides of similar triangles are equal.

angle M and G are both 90° , this means they are equal.

angle KVM = BVG

therefore angle K = angle B

Since all the corresponding angles are equal, we can say triangle KVM is similar to triangle BVG

Answer:

1. x = {-3, 3}

2. a = {-12, -2}

3. v = {-7, 10}

4. m = {-8, 8}

5. k = {-11, 1}

6. y = {-13, 19}

Step-by-step explanation:

|-2x| = 6

means that

-2x = 6     or      -2x = -6

x = -3        or      x = 3

|a + 7| = 5

means that

a + 7 = 5    or      a + 7 = -5

a = -2        or      a = -12

|8v-12| = 68

means that

8v-12 = 68     or      8v-12 = -68

8v = 80        or      8v = -56

v = 10            or      v = -7

| m / -4 | + 1 = 3

| m / -4 | = 2

means that

m/-4 = 2     or      m/-4 = -2

m = -8        or      m = 8

3|k + 5| = 18

|k+5| = 6

means that

k + 5 = 6    or      k + 5 = -6

k = 1        or      k = -11

|2y - 6| / 4 = 8

|2y - 6| = 32

means that

2y - 6 = 32     or      2y - 6 = -32

y = 19        or      m = -13

To calculate the density of the metal, we need to use the formula: Density = Mass/Volume. In this case, the mass of the metal is given as 53.435 pounds.

However, we need to convert it to grams since the density is typically measured in grams per milliliter (g/mL). One pound is approximately equal to 453.592 grams. So, the mass of the metal can be converted to grams by multiplying 53.435 pounds by 453.592 grams/pound.

Next, we need to determine the volume of the metal in milliliters. The initial volume of the graduated cylinder was 3.585L, and after placing the metal in the cylinder, the volume read 9.648L. The difference in volume, 9.648L - 3.585L, represents the volume occupied by the metal.

Now, we can substitute the values into the density formula. Density = Mass/Volume = (53.435 pounds * 453.592 grams/pound) / (9.648L - 3.585L). The result will give us the density of the metal in grams per milliliter (g/mL). It's important to note that the final density value will depend on the accuracy and precision of the given measurements.

Type I error can occur in any study or experiment, and it highlights the importance of considering the possibility of false positive results when interpreting statistical findings.

A randomized trial comparing the efficacy of two drugs showed a difference between the two (with a P-value < 0.05). Assume that in reality, however, the two drugs do not differ. This is, therefore, an example of a Type I error.

In statistics, a Type I error occurs when the null hypothesis is rejected, even though it is true. In this case, the null hypothesis would state that there is no difference between the two drugs. However, due to random chance or other factors, the trial yielded a statistically significant result indicating a difference between the drugs.

The equation, when stated to be either direct or inverse variation, and the possible constants of variation, are:

To determine whether 7x + 8y = -1 represents a direct or inverse variation, we need to rewrite it in the form y = kx or y = k/x.

y = (-7/8)x - 1/8

Since the equation is in the form y = (-7/8)x - 1/8, it has a constant term (-1/8), which means it does not represent a direct variation (y = kx). Since the equation is not in the form y = k/x or xy = k, it does not represent an inverse variation either.

The equation 5x = 25/y:

First, multiply both sides by y:

5xy = 25

Referring to exhibit 8-2, we can see that the sample size is 400, and the population standard deviation is 10.

Based on these values, we can use the formula for the margin of error:
Margin of error = Z * (σ/√n)
Where Z is the Z-score for the desired level of confidence (in this case, 0.95), σ is the population standard deviation, and n is the sample size. Using a Z-score of 1.96 (which corresponds to a 0.95 confidence level), we can plug in the values:
Margin of error = 1.96 * (10/√400)
Simplifying this equation, we get:
Margin of error = 1.96 * (10/20) = 0.98
Therefore, with a 0.95 probability, the sample mean will provide a margin of error of approximately 0.98.
Based on Exhibit 8-2, with a 0.95 probability, the sample mean will provide a margin of error of "X" (please insert the value provided in the exhibit). This means that we can be 95% confident that the true population mean lies within the sample mean ± X.

Answer:

Step-by-step explanation:

If you graph it you can figure out the starting point of the parallel line.

The rate of change is 2 and since the point the parallel line needs to pass through is (-1,3) you need to shift the starting point (y-intercept) up by 10 units.

Shifting the y-intercept of y=2x-5 up by 10 makes the new line y=2x+5.

Answer:

33.51 units³

Step-by-step explanation:

Volume of a sphere is given by the formula :

V = \(\frac{4}{3} \pi r^{3}\)

Because we have the radius we can plug it into the equation to give us :

V  = (4/3)×π×(2)³

V = 4/3×8π

V ≈ 33.51

Units will be units³ since no measurement is given but it to the power of 3 since it is volume.

Answer:

\(y = -\frac{7}{10}x + \frac{4}{5}\)

Step-by-step explanation:

Parallel lines have the same slope.

Given that line s is represented by the linear equation, \(y = -\frac{7}{10}x - 1\),  then line t must have the same slope of  \(-\frac{7}{10}\).

All we have to do at this point is use line t's slope, m = \(-\frac{7}{10}\), and the given point, (-6, 5), to solve for the y-intercept, b:

y = mx + b

\(5 = -\frac{7}{10}(-6) + b\)

\(5 = \frac{42}{10} + b\)

\(5 = \frac{21}{5} + b\)

Subtract \(\frac{21}{5}\) from both sides:

\(5 - \frac{21}{5} = \frac{21}{5} - \frac{21}{5} + b\)

\(\frac{4}{5}\) = b

Therefore, the equation of line t  that is parallel to line s is:  \(y = -\frac{7}{10}x + \frac{4}{5}\).

If we sample the function x(t) = cos(75t) at the Nyquist frequency, the resulting discrete frequency would be half of the Nyquist frequency, which is equal to half of the highest frequency component in the continuous signal.

In this case, the highest frequency component in x(t) is 75 Hz, as determined by the coefficient of t in the cosine function. According to the Nyquist-Shannon sampling theorem, to accurately represent a signal, the sampling frequency must be at least twice the highest frequency component. Therefore, the Nyquist frequency in this scenario would be 2 * 75 Hz = 150 Hz.

Since we are sampling at the Nyquist frequency, the resulting discrete frequency would be half of the Nyquist frequency, which is 150 Hz / 2 = 75 Hz. Hence, when sampling x(t) at the Nyquist frequency, the resulting discrete frequency would be 75 Hz.

a. Null hypothesis (H0): μ1 = μ2 and Alternative hypothesis (H1): μ1 < μ2. b. The test statistic is -2.57 and p-value is  0.005 for the hypothesis test. c. At α = 0.05 it can be concluded that CPAs in states with flat state income tax rates work fewer hours per week during tax season compared to the average U.S. CPAs.

a. First, let's formulate the hypotheses:

Null hypothesis (H0): μ1 = μ2, which means that the mean hours worked per week during tax season by CPAs in states with flat state income tax rates is equal to the mean hours worked per week by all U.S. CPAs during tax season.

Alternative hypothesis (H1): μ1 < μ2, which means that the mean hours worked per week during tax season by CPAs in states with flat state income tax rates is less than the mean hours worked per week by all U.S. CPAs during tax season.

b. Now, let's compute the test statistic and p-value using the given sample data:

Sample mean (x) = 55 hours

Population mean (μ) = 60 hours

Population standard deviation (σ) = 27.4 hours

Sample size (n) = 150

We'll use the z-test for this hypothesis test:

z = (x - μ) / (σ / √n) = (55 - 60) / (27.4 / √150) ≈ -2.57

To find the p-value, we need to look up the z-value in the standard normal table, which gives us a p-value of approximately 0.005.

c. Lastly, let's draw our conclusion using α = 0.05:

Since the p-value (0.005) is less than α (0.05), we reject the null hypothesis (H0). This suggests that CPAs in states with flat state income tax rates work fewer hours per week during tax season compared to the average U.S. CPAs.
