Step-by-step explanation:

If they are vertical angles, they are opposite to each other where two lines intersect. Vertical angles are equal to each other so

5x-15=3x+1

2x-15=1

2x=16

x=8 degrees.

The angles are

a=5x-15, and x=8 so

a=5(8)-15

a=40-15

a=25 degrees.

Euclid receives 20 shares of common stock as a nontaxable stock dividend.The basis of the common stock remains the same as in scenario a, which is $96.15 per share.

To calculate the per share basis, we divide the original purchase cost by the total number of shares (including the dividend shares).  In scenario b, Euclid receives a nontaxable preferred stock dividend of 20 shares. The preferred stock has a fair market value of $5,000, and the common stock, on which the preferred is distributed, has a fair market value of $75,000.

The tax consequences involve determining the new basis of the preferred stock and the common stock after the dividend. a. To find the per share basis of Euclid's common stock after receiving the stock dividend, we divide the original purchase cost by the total number of shares. The original purchase cost was $50,000 for 500 shares, which means the per share basis was $50,000/500 = $100. After receiving 20 additional shares as a dividend, the total number of shares becomes 500 + 20 = 520.

Therefore, the new per share basis is $50,000/520 = $96.15. b. In this scenario, Euclid receives a preferred stock dividend of 20 shares. The preferred stock has a fair market value of $5,000, and the common stock has a fair market value of $75,000. To determine the new basis of the preferred stock, we consider its fair market value.

Since the preferred stock dividend is nontaxable, its basis is equal to the fair market value, which is $5,000.

Answer:

I'd say yes, because you have a good variety of samples. (B.)

Step-by-step explanation:

If the sample size is n=40 ,mean of 20 and a standard deviation then the sampling distribution is normally distributed.

Given sample size is 40, sample mean is 20, sample standard deviation is 5.

We have to find whether the distribution is normally distributed or not.

Normal distribution is an arrangement of a data set in which most values cluster in the middle of the range and the rest taper off simultaneously towards either extreme. It may be one tailed or two tailed also.

Yes the given distribution whose sample size is 40, sample mean of 20 and sample standard deviation of 5 is normally distributed as the sample size is greater than 30.

Signs of normal distribution are:

Answer: \(y=\frac{1}{7}x+19\)

Step-by-step explanation:

Perpendicular lines have slope that are negative reciprocals, so the slope of the line we want to find is 1/7.

The equation in point-slope form is \(y-21=\frac{1}{7}(x-14)\).

Rearranging into slope-intercept form,

\(y-21=\frac{1}{7}x-2 \\ \\ y=\frac{1}{7}x+19\)

Answer: x=10.5

Step-by-step explanation:

To solve for x, we want to use our properties to isolate x.

2x-7=14           [add both sides by 7]

2x=21              [divide both sides by 2]

x=10.5

Now, we know that x=10.5.

When swerving, there are a number of factors that come into play, including traction, lean, load triangle, and being upright. Swerving in a straight line can be relatively easy, as the rider only needs to make minor adjustments to maintain balance.

When comparing swerving in a straight line to swerving in a curve, the key differences involve traction and maintaining an appropriate lean angle.
Swerving in a curve requires more traction than swerving in a straight line. Traction is essential for maintaining control of your vehicle, especially when navigating curves. As you swerve in a curve, your tires need to have a good grip on the road surface to prevent skidding or losing control.
Additionally, managing lean angles is more critical when swerving in a curve. To maintain balance and control, you must avoid leaning too much, as it can cause the vehicle to tip over or slide out. In a curve, the lean angle needs to be adjusted appropriately to match the curve's radius, while also considering your speed and road conditions.
In summary, swerving in a curve requires more traction and careful management of lean angles compared to swerving in a straight line. The load triangle and keeping the vehicle upright are important, but they are not the primary factors that make swerving in a curve more challenging than swerving in a straight line.

The value of p(0 ≤ z ≤ 1.37) is approximately 0.41 (rounded to 2 decimal places).

What is Probability ?

Probability is a branch of mathematics that deals with the study of the likelihood or chance of an event occurring. It is the measure of the likelihood that a particular event or set of events will occur.

To find the value of p(0 ≤ z ≤ 1.37) using Appendix C-1, we need to locate the row containing 0.1 in the far-left column and the column containing 0.37 in the top row.

Starting with the row containing 0.1 in the far-left column, we can locate the value closest to 1.3 in the row, which is 1.37. Moving along the row to the right, we can find the corresponding value of the cumulative distribution function (CDF) for this value of z, which is 0.9147.

Next, we need to find the column containing 0.37 in the top row. The closest value in the column is 0.3707. Moving down the column to the row containing the CDF value we just found, we can read off the value of the CDF for z = 0, which is 0.5000.

To find the value of p(0 ≤ z ≤ 1.37), we subtract the CDF value for z = 0 from the CDF value for z = 1.37:

p(0 ≤ z ≤ 1.37) = 0.9147 - 0.5000 = 0.4147

Therefore, the value of p(0 ≤ z ≤ 1.37) is approximately 0.41 (rounded to 2 decimal places).

The ratio of the blue fish in the small tank to red fish in the large tank is 10 to 69.

Ratio is the relationship between two quantities.

Let x : y = ratio of the blue fish in the small tank to red fish in the large tank

Hence, there are x blue fish in the small tank for every y red fish in the large tank.

If in each tank, the ratio of red fish to blue fish is 3 to 4, then in each tank, in terms of x and y, the ratio is:

small tank :

red : blue = 3 : 4 = (3/4)x : x

large tank :

red : blue = 3 : 4 = y : (4/3)y

If the ratio of fish in the large tank to fish in the small tank is 46 to 5, then

(y + (4/3)y) : ((3/4)x + x) = 46 : 5

Simplifying the proportion,

(y + (4/3)y) : ((3/4)x + x) = 46 : 5

(7/3)y : (7/4)x = 46 : 5

(161/2)x = (35/3)y

x/y = (35/3) / (161/2)

1) The relationship between ∠1 and ∠3 is that they are corresponding angles.

2) The relationship between ∠8 and ∠4 is that they are alternate exterior angles

3) The relationship between ∠2 and ∠3 is that they are supplementary angles.

When it comes to congruent angles, we know that when two parallel lines are intersected by a third one, the angles that occupy the same relative position at each intersection are known to be corresponding angles to each other.

Now, in the first figure, we see that there are a total of eight angles and we also see that 2 parallel lines have been intersected by a third one. Thus, some of the angles will be congruent to others. In this case, we see that the relationship between ∠1 and ∠3 is that they are corresponding angles.

Now, in the second figure, we see that there are a total of eight angles and we also see that 2 parallel lines have been intersected by a third one.

Using the constant of proportionality, the time taken is 6 minutes

To solve this problem, we need to use variation with the help of proportionality.

Since the relationship is inversely proportional, we can write it as;

speed = k / size

constant of proportionality = k

12 = k / 256

k = 12 * 256

k = 3072

Using this, we can determine the speed or time

512 = 3072 / size

size = 3072 / 512

We have a continuous random variable over -2 < x < 5 so p(x = 1) = 0 because the probability at any given point for any continuous random variable is always 0.

Probability is a measure of the likelihood of a particular event occurring. It is expressed as a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is certain to happen.

Probability at any given position is always zero for any continuous random variable. This is because the probability of a single value occurring for a continuous random variable is always 0 because the range of values for the random variable is infinite and therefore the probability of a single value occurring is 0.

Answer:

t is 7

Step-by-step explanation:

i did it

Answer:

7. To perform a t-test when the sample size is small, the sample must show no evidence of strong skewness and must contain no outliers.

Step-by-step explanation:

These are the two conditions required for performing a t test

- Sample Size: A small sample size can reduce the statistical power of a t-test, making it more challenging to detect significant differences between groups. Generally, a larger sample size is desirable to obtain more reliable and representative results.

- Skewness: Skewness refers to the asymmetry of the distribution of data. In a t-test, assuming normality of the data is important for accurate results. If the data exhibits strong skewness, the assumption of normality may be violated. In such cases, alternative non-parametric tests or transformations of the data may be more appropriate.

- Outliers: Outliers are extreme values that significantly differ from the rest of the data. They can have a disproportionate impact on the results of a t-test, particularly when the sample size is small. Outliers can distort the mean and affect the assumptions of normality and homogeneity of variance.

While the presence of skewness or outliers does not prohibit the use of a t-test with a small sample size, it is important to interpret the results with caution and consider alternative approaches if necessary. Robust statistical methods, such as non-parametric tests or bootstrapping, can be useful when dealing with non-normal or outlier-prone data, especially with small sample sizes. Additionally, visual inspection of the data distribution, such as through histograms or box plots, can help identify potential skewness or outliers.

Options:

\(A.\ (\frac{3}{2}, \frac{9}{2})\)

\(B.\ (-1, 1)\)

\(C.\ (4, 16)\)

\(D.\ (\frac{1}{2}, \frac{1}{4})\)

Answer:

\(A.\ (\frac{3}{2}, \frac{9}{2})\)

Step-by-step explanation:

Given

\(y = x^2\)

Required

Determine which of the given points is not true

\(A.\ (\frac{3}{2}, \frac{9}{2})\)

Here

\(x = \frac{3}{2}\) and \(y = \frac{9}{2}\)

Substitute these values in \(y = x^2\)

\(\frac{9}{2} = (\frac{3}{2})^2\)

\(\frac{9}{2} = \frac{3}{2}*\frac{3}{2}\)

\(\frac{9}{2} \ne \frac{9}{4}\)

Both sides of the equation are not equal. Hence, this point do not line on the curve

\(B.\ (-1, 1)\)

Here

\(x = -1\)  and \(y = 1\)

Substitute these values in \(y = x^2\)

\(1 = (-1)^2\)

\(1=1\)

Both sides of the equation are equal. Hence, this point line on the curve

\(C.\ (4, 16)\)

Here

\(x = 4\)  and \(y = 16\)

Substitute these values in \(y = x^2\)

\(16 = 4^2\)

\(16 = 16\)

Both sides of the equation are equal. Hence, this point line on the curve

\(D.\ (\frac{1}{2}, \frac{1}{4})\)

Here

\(x = \frac{1}{2}\)  and \(y = \frac{1}{4}\)

Substitute these values in \(y = x^2\)

\(\frac{1}{4} = (\frac{1}{2})^2\)

\(\frac{1}{4} = \frac{1}{2}*\frac{1}{2}\)

\(\frac{1}{4} = \frac{1}{4}\)

Both sides of the equation are equal. Hence, this point line on the curve

From the calculations above; only \(A.\ (\frac{3}{2}, \frac{9}{2})\) do no lie on the curve
