To find r , divide the 2nd term by the 1st term or the 3rd term by the 2nd term.
Now r = 3/4 or g/3. To find g now, the two can be equated together and solve for g or by multiplying the 2nd term by the common ratio.
(1) r = 3/4 ……………………,(1)

r =. g/3……………………..(2)

g = 3/4 x 3

= 9/4. or

3/4 = g/4, by cross multiplying the equation, it now becomes

4g = 3 x3

4g = 9

Now divide both dude by the coefficient of g which is 4

g = 9/4

The interval estimate of the population mean is equal to 2.09 < h < 2.35.

In Mathematics and statistics, a confidence interval is sometimes referred to as level of confidence and it can be defined as a range of estimated values that defines the probability that a population parameter would fall or lie within it.

In Mathematics and statistics, the margin of error (MOE) can be defined as a measure of the difference that exist between an observed value and a true value of the population parameter.

Based on the information provided about these 50 apples that were randomly selected, the confidence interval at 95% is given by:

x ± E

x - E < h < x + E

2.22 - 0.13 < h < 2.22 + 0.13

2.09 < h < 2.35

If your argument leads to a misleading conclusion, it is probably unsound. It is also conceivable that the argument is sound but has a wrong premise.

If an argument has a faulty conclusion, either the premises are incorrect or the conclusion does not flow logically from the premises. This indicates that the reasoning is flawed.

An argument is deemed sound if all of its premises are true and it is valid (that is, the conclusion flows logically from the premises). Whether or not the conclusion is correct, the argument is flawed if any of the premises are untrue.

As a result, if your argument leads to a misleading conclusion, it is probably unsound. It is also conceivable that the argument is sound but has a wrong premise, in which case it is invalid.

Answer:

y = -5/6x - 2

Step-by-step explanation:

The y-intercept is -2 because that is where the line crosses the y-axis Remember that slope is rise/run (there are many other terms for slope but this is the one I will reference). Therefore, the slope from one point to the next is down 5 and over 6. Since this is a decreasing slope (down 5), your slope will be negative

Cindy should hire the 12th worker as it would result in a net increase in profit, with additional revenue exceeding the cost of hiring. Insufficient information is provided to determine the demand curve for labor or compare its elasticity. Events that would shift the factory's demand for capital include new, more efficient machines and rising wages due to a labor shortage.

a. To determine whether Cindy should hire a 12th worker, we need to compare the additional revenue generated with the additional cost incurred. Hiring the 12th worker would increase total revenue by $150 ($2,750 - $2,600) per day, but it would also increase costs by $100. Therefore, the net increase in total profit would be $50 ($150 - $100). Since the net increase in profit is positive, Cindy should hire the 12th worker.

b. By hiring the 12th worker, Cindy can increase her total revenue from $2,600 per day to $2,750 per day. The additional revenue generated by the 12th worker exceeds the cost of hiring that worker, resulting in a net increase in profit.

c. To determine the firm's demand curve for labor, we need information about the marginal product of labor (MPL) and the wage rates. Unfortunately, this information is not provided, so we cannot complete the labor demand table or derive the demand curve for labor.

Without specific data or information about changes in the quantity of labor demanded and wage rates, we cannot determine which demand curve (from part b or c) is more elastic. The elasticity of the demand curve depends on the responsiveness of the quantity of labor demanded to changes in the wage rate.

The events that would shift the factory's demand for capital are:

a. New shoemaking machines being twice as efficient as older machines would increase the productivity of capital. This would lead to an increase in the demand for capital as the factory would require more capital to produce the same quantity of shoes.

b. The wages that the factory has to pay its workers rising due to an economy-wide labor shortage would increase the cost of labor relative to capital. This would make capital relatively more attractive and lead to an increase in the demand for capital as the factory may substitute capital for labor to maintain production efficiency.

The event "Many consumers decide to walk barefoot all the time" would not directly impact the demand for capital as it is related to changes in consumer behavior rather than the production process of the shoemaking factory.

The critical value of the test statistic t for a one-tailed (upper tail) hypothesis test with a sample size of 26 and a significance level of 0.01 is 2.479. This value is used to determine whether the sample data provides enough evidence to reject the null hypothesis in favor of the alternative hypothesis.

If the calculated test statistic is greater than 2.479, it falls into the critical region, and we reject the null hypothesis. Conversely, if the calculated test statistic is less than 2.479, it does not fall into the critical region, and we fail to reject the null hypothesis. The critical value is determined based on the desired level of significance and the degrees of freedom, which in this case is 26 - 1 = 25. For a one-tailed test with a significance level of 0.01, we need to find the t-value that corresponds to the 0.99 percentile of the t-distribution with 25 degrees of freedom. By consulting the t-distribution table or using statistical software, we find that the critical value is 2.479. This means that the calculated test statistic must be greater than 2.479 for us to reject the null hypothesis in favor of the alternative hypothesis at the 0.01 significance level in the upper tail of the distribution.

The linear model that represents the cost of any number of candy bars can be written as: C = $1.90B + $0.95

To write the linear model that models the cost of any number of candy bars, we need to find the equation of a line that best fits the given data points. We'll use the variables B for the number of candy bars purchased and C for the total cost of the candy bars.

Looking at the given data, we can see that there is a linear relationship between the number of candy bars and the total cost. As the number of candy bars increases, the total cost also increases.

To find the equation of the line, we need to determine the slope and the y-intercept. We can use the formula for the equation of a line: y = mx + b, where m is the slope and b is the y-intercept.

First, let's find the slope (m) using two points from the given data, for example, (3, $6.65) and (25, $48.45):

m = (C2 - C1) / (B2 - B1)

 = ($48.45 - $6.65) / (25 - 3)

 = $41.80 / 22

 ≈ $1.90

Now, let's find the y-intercept (b) using one of the data points, for example, (3, $6.65):

b = C - mB

 = $6.65 - ($1.90 * 3)

 = $6.65 - $5.70

 ≈ $0.95

Therefore, the linear model that represents the cost of any number of candy bars can be written as:

C = $1.90B + $0.95

This equation represents a linear relationship between the number of candy bars (B) and the total cost (C). For any given value of B, you can substitute it into the equation to find the corresponding estimated total cost of the candy bars.

The mean arterial pressure formula is MAP = CO x TPR or MAP = (SBP + 2DBP) / 3.

The mean arterial pressure (MAP) formula is:

MAP = CO x TPR

where:

CO is the cardiac output (how much blood is siphoned by the heart each moment)

TPR is the all-out peripheral resistance (the resistance from the bloodstream in the body's veins)

On the other hand, the mean arterial pressure can also be calculated using the following equation:

MAP = (SBP + 2DBP)/3

where:

SBP is the systolic blood pressure (the highest pressure in the arteries when the heart beats)

DBP is the diastolic blood pressure(the lowest pressure in the arteries when the heart is at rest between beats)

Case 1

Total number of students =(x−1)(y+3)

⇒xy=(x−1)(y+3)=xy−y+3x−3

⇒3x−y−3=0

⇒3x−y=3..... (i)

Case 2

Total number of students=(x+2)(y−3)

⇒xy=xy+2y−3x−6

⇒3x−2y=−6..... (ii)

Subtracting equation (ii) from (i),

⇒(3x−y)−(3x−2y)=3−(−6)

⇒−y+2y=3+6
