Answer:
n = 2
Step-by-step explanation:
Given nx + y = 4, if we rearrange in slope-intercept form: y = -nx + 4
This means that the y-intercept is 4. Point "A" is the y-intercept, which would make OA = 4, and OB = 1/2(4) = 2.
We can now solve for n. The slope here is "-n", also represented by rise/run or OA/-OB = 4/-2 = -2.
-n = -2,
n = 2

which is the smallest measurement used in the apothecary system for volume? a. apothecary b. metric c. minim d. household.
The smallest measurement used in the apothecary system for volume is the minim.
The apothecary system is an outdated system of measurements primarily used in pharmacy and medicine. It includes various units for measuring volume, weight, and other quantities.
In the apothecary system, the minim is the smallest unit of measurement for volume. It is equivalent to approximately 0.0616 milliliters.
The minim is a small unit of measurement and is typically used for precise dosing of liquids in the apothecary system. It is commonly used in pharmaceutical compounding and in the preparation of medications.
However, it's important to note that the apothecary system is no longer widely used in modern healthcare practices. The metric system, with units such as milliliters and liters, has become the standard for measuring volume in most countries.

In the given problem, random samples of four different models of cars were selected and the gas mileage of each car was measured. The results are shown below:21 226 22 725 21
Given that,The null hypothesis H0: All the population means are equal. The alternative hypothesis H1: At least one population mean is different from the others .
To find the hypothesis test, we will use the one-way ANOVA test. We calculate the grand mean (X-bar) and the sum of squares between and within to obtain the F-test statistic. Let's find out the sample size (n), the total number of samples (N), the degree of freedom within (dfw), and the degree of freedom between (dfb).
Sample size (n) = 4 Number of samples (N) = n × 4 = 16 Degree of freedom between (dfb) = n - 1 = 4 - 1 = 3 Degree of freedom within (dfw) = N - n = 16 - 4 = 12 Total sum of squares (SST) = ∑(X - X-bar)2
From the given data, we have X-bar = (21 + 22 + 26 + 25) / 4 = 23.5
So, SST = (21 - 23.5)2 + (22 - 23.5)2 + (26 - 23.5)2 + (25 - 23.5)2 = 31.5 + 2.5 + 4.5 + 1.5 = 40.0The sum of squares between (SSB) is calculated as:SSB = n ∑(X-bar - X)2
For the given data,SSB = 4[(23.5 - 21)2 + (23.5 - 22)2 + (23.5 - 26)2 + (23.5 - 25)2] = 4[5.25 + 2.25 + 7.25 + 3.25] = 72.0 The sum of squares within (SSW) is calculated as:SSW = SST - SSB = 40.0 - 72.0 = -32.0
The mean square between (MSB) and mean square within (MSW) are calculated as:MSB = SSB / dfb = 72 / 3 = 24.0MSW = SSW / dfw = -32 / 12 = -2.6667
The F-statistic is then calculated as:F = MSB / MSW = 24 / (-2.6667) = -9.0
Since we are testing whether at least one population mean is different, we will use the F-test statistic to test the null hypothesis. If the p-value is less than the significance level, we will reject the null hypothesis. However, the calculated F-statistic is negative, and we only consider the positive F-values. Therefore, we take the absolute value of the F-statistic as:F = |-9.0| = 9.0The p-value corresponding to the F-statistic is less than 0.01. Since it is less than the significance level (α = 0.05), we reject the null hypothesis. Therefore, we can conclude that at least one of the population means is different from the others.

Answer:
y= 2/3x + 4
Step-by-step explanation:
Slope form is written like this:
y = mx + b
We need to find m (the slope) and b (the y intercept)
To get from one dot to the other, we go up 2 and to the right 3. The slope is written like rise over run. rise is the change in y and run is the change in x.
The slope is 2/3
Th y intercept is simply where the line touches on the y intercept. (0, 4)

Assume that when you were in high school you saved $1,000 to invest for your college education. You purchased 200 shares of Smiley Incorporated, a small but growing company. Over the three years that you have owned the stock, the corporation's board of directors has taken the following actions:
Declared a 2-for-1 stock split.
Declared a 20 percent stock dividend.
Declared a 3-for-1 stock split.
The current price of the stock is $12 per share.
a. Calculate the current number of shares and the market value of your investment.
current number of shares
market value
b) the current number of shares is 1440, and the market value of your investment is $17,280.
To calculate the current number of shares and the market value of your investment, we need to take into account the stock splits and stock dividends.
Given:
Initial investment: $1,000
Initial number of shares: 200
Current price per share: $12
a. Calculate the current number of shares:
First, let's consider the stock splits and stock dividends:
1. 2-for-1 stock split:
This means that for each existing share, you now have two shares. So the number of shares is doubled.
New number of shares = Initial number of shares * 2 = 200 * 2 = 400 shares.
2. 20% stock dividend:
A 20% stock dividend means you receive an additional 20% of your current number of shares. To calculate the number of shares received:
Shares received = Current number of shares * (20% / 100%)
Shares received = 400 * (20 / 100) = 80 shares.
Total number of shares after the dividend = Current number of shares + Shares received = 400 + 80 = 480 shares.
3. 3-for-1 stock split:
This means that for each existing share, you now have three shares. So the number of shares is tripled.
New number of shares = Total number of shares after the dividend * 3 = 480 * 3 = 1440 shares.
The current number of shares you have is 1440.
b. Calculate the market value of your investment:
Market value = Current number of shares * Current price per share
Market value = 1440 * $12 = $17,280

Which will be smoother, a 50-day or a 200-day moving average?50-day 200-day
Due to its larger time frame and less sensitivity to transient variations in the data, the 200-day moving average is often smoother than the 50-day moving average.
The 200-day moving average is typically smoother than the 50-day moving average because it covers a longer period of time and is therefore less reactive to short-term fluctuations in the data. However, the choice between using a 50-day or a 200-day moving average ultimately depends on the specific data being analyzed and the desired level of sensitivity to changes in the data.
A 200-day moving average will be smoother than a 50-day moving average. The 200-day moving average considers a longer period of time, which reduces the impact of short-term fluctuations and provides a clearer overall trend. The 50-day moving average is more sensitive to recent price changes and will appear more volatile in comparison.

Maximizing the power of an experiment _________. A. minimizes alpha B. minimizes beta C. increases the probability of rejecting H0 when H0 is true D. increases the probability of making a Type II error
Maximizing the power of an experiment increases the probability of rejecting H0 when H0 is true, so the answer is C.
The power of an experiment is the probability of correctly rejecting the null hypothesis (H0) when the alternative hypothesis (Ha) is true. In other words, it is the probability of avoiding a Type II error (failing to reject a false null hypothesis).By maximizing the power of an experiment, we increase the likelihood of detecting a true effect if it exists, which reduces the chances of making a Type II error (accepting a false null hypothesis).
Alpha (Type I error rate) and beta (Type II error rate) are related to the significance level and the power of an experiment, but maximizing the power of an experiment does not minimize alpha or beta directly.
