The correct answer is c. $100,000.

The required reserve ratio is the percentage of deposits that banks are required to hold as reserves. In this case, Bank A has total deposits of $10 million and the required reserve ratio is 9 percent. Therefore, Bank A is required to hold reserves equal to 9% of its deposits, or:

Reserves required = 0.09 x $10,000,000 = $900,000

However, the bank currently has actual reserves of $1 million, which means it has excess reserves equal to:

Excess reserves = Actual reserves - Reserves required

Excess reserves = $1,000,000 - $900,000 = $100,000

Therefore, the correct answer is c. $100,000.

The freezing point is normally distributed with mean of 0 degrees celsius and a standard deviation of 1 degree celsius. The probability of getting a score between -1.5 and 2.5 is 0.9332.

To find the probability of getting a score between -1.5 and 2.5, we need to find the area under the normal distribution curve for this range using a z-score table.

First, we need to convert the range into standard units, which is done by subtracting the mean and dividing by the standard deviation:

z1 = ( -1.5 - 0 ) / 1 = -1.5

z2 = ( 2.5 - 0 ) / 1 = 2.5

Next, we look up the z-scores in a z-score table to find the area under the normal curve:

P(-1.5 < Z < 2.5) = 0.9332

This means that the probability of getting a score between -1.5 and 2.5 is 0.9332 or 93.32%.

The percentage strength of neomycin in the final compounded product is approximately 2.5%.

To determine the percentage strength of neomycin in the final compounded product, we need to calculate the weight of neomycin in the cream and divide it by the total weight of the cream.

Neomycin (5%) cream: 30g

The neomycin content is 5% of the total cream weight. To find the weight of neomycin in the cream, we multiply the cream weight by the neomycin percentage:

Weight of neomycin = 30g × 0.05 = 1.5g

Now, to calculate the percentage strength of neomycin in the final compounded product, we divide the weight of neomycin by the total weight of the cream and multiply by 100:

Percentage strength of neomycin = (Weight of neomycin / Total weight of cream) × 100

Percentage strength of neomycin = (1.5g / 60g) × 100 ≈ 2.5

Therefore, the percentage strength of neomycin in the final compounded product is approximately 2.5%.

The outcome variable in a linear regression is best measured on continuous scales. Linear regression is a statistical method that is used to establish the correlation between two continuous variables.

Linear regression is used to establish a relationship between an independent variable (predictor) and a dependent variable (outcome). In a linear regression model, the outcome variable should be a continuous variable. Linear regression models cannot be applied to categorical or ordinal variables.

Linear regression is a statistical method that is used to establish the correlation between two continuous variables. In a linear regression model, the outcome variable (also called the dependent variable) should be a continuous variable that can take any numerical value within a certain range.

Continuous variables are variables that are measured on a continuous scale, meaning that the difference between two values is meaningful. For example, height, weight, and temperature are continuous variables.In contrast, categorical variables are variables that can take on a limited number of values, such as gender or race.

Ordinal variables are variables that can be ordered but the difference between two values is not meaningful, such as a Likert scale.

Linear regression models cannot be applied to categorical or ordinal variables because the model assumes that the relationship between the independent and dependent variable is linear and that the residuals (the difference between the predicted and actual values) are normally distributed.

Therefore, the outcome variable in a linear regression is best measured on continuous scales.

The expression y(x) = C₁y₁(x) + C₂y₂(x) satisfies the given differential equation. Since any solution y(x) of the differential equation can be expressed in this form, we have proven that all solutions y(x) of the differential equation have the form: y(x) = C₁y₁(x) + C₂y₂(x), where C₁ and C₂ are constants determined by initial or boundary conditions.

To prove that all solutions y(x) of the differential equation have the form: y(x) = C₁y₁(x) + C₂y₂(x), we need to show that any solution of the given differential equation can be expressed as a linear combination of the functions y₁(x) and y₂(x).

Let y(x) be any solution of the differential equation. Since {y₁(x), y₂(x)} is a fundamental set of solutions on interval I, we can express y(x) as a linear combination of these two functions:

y(x) = C₁y₁(x) + C₂y₂(x)

where C₁ and C₂ are constants determined by initial or boundary conditions.

Now, we need to show that this expression for y(x) satisfies the differential equation.

Taking the first and second derivatives of y(x), we get:

y'(x) = C₁y₁'(x) + C₂y₂'(x)

y''(x) = C₁y₁''(x) + C₂y₂''(x)

Substituting these expressions into the given differential equation, we obtain:

a(z)(C₁y₁''(x) + C₂y₂''(x)) + a₁(z)(C₁y₁'(x) + C₂y₂'(x)) + ao(z)(C₁y₁(x) + C₂y₂(x)) = 0

Since {y₁(x), y₂(x)} is a fundamental set of solutions, we know that they satisfy the differential equation individually:

a(z)y₁''(x) + a₁(z)y₁'(x) + ao(z)y₁(x) = 0

a(z)y₂''(x) + a₁(z)y₂'(x) + ao(z)y₂(x) = 0

Therefore, we can substitute these expressions into the previous equation and simplify:

a(z)(C₁y₁''(x) + C₂y₂''(x)) + a₁(z)(C₁y₁'(x) + C₂y₂'(x)) + ao(z)(C₁y₁(x) + C₂y₂(x))

= C₁(a(z)y₁''(x) + a₁(z)y₁'(x) + ao(z)y₁(x)) + C₂(a(z)y₂''(x) + a₁(z)y₂'(x) + ao(z)y₂(x))

= C₁(0) + C₂(0)

= 0

Therefore, the expression y(x) = C₁y₁(x) + C₂y₂(x) satisfies the given differential equation. Since any solution y(x) of the differential equation can be expressed in this form, we have proven that all solutions y(x) of the differential equation have the form: y(x) = C₁y₁(x) + C₂y₂(x), where C₁ and C₂ are constants determined by initial or boundary conditions.

Answer:1.414 rounded to the nearest thousandths

Step-by-step explanation:

An advance in technology in the production of good X causes:

c) a rightward shift in the supply curve for good X.

An advance in technology typically increases the efficiency of production and reduces the costs of production. This results in an increase in the quantity of goods that can be produced at a given price, causing the supply curve to shift to the right. The shift to the right reflects an increase in supply, meaning that at any given price, there is now a larger quantity of goods available for sale. This increase in supply tends to put downward pressure on the market price.

The determination of a rightward shift in the supply curve as a result of an advance in technology can be made through analyzing the relationship between price and quantity supplied using basic microeconomic principles.

The supply curve represents the relationship between the price of a good and the quantity of that good that producers are willing and able to supply to the market. An advance in technology that leads to an increase in production efficiency and a decrease in production costs can increase the quantity of goods that can be produced at any given price.

As a result, the supply curve will shift to the right, reflecting an increase in the quantity of goods supplied at each price point. This shift to the right indicates that there is now a larger quantity of goods available for sale at any given price, which can put downward pressure on the market price.

A significance level of 0.10, we have enough evidence to conclude that the new copy machines have a significantly faster mean repair time compared to the older model.

To test if the new copy machines are faster to repair, we can set up the following null and alternative hypotheses:

Null Hypothesis (H₀): The mean repair time for the new copy machines is the same as the mean repair time for the older model.

Alternative Hypothesis (H₁): The mean repair time for the new copy machines is less than the mean repair time for the older model.

Let's perform a one-sample t-test to test these hypotheses. The test statistic is calculated as:

t = (sample mean - population mean) / (sample standard deviation / √(sample size))

Given:

Population mean (μ) = 93 minutes

Sample mean (\(\bar x\)) = 86.8 minutes

Sample standard deviation (s) = 14.6 minutes

Sample size (n) = 18

Significance level (α) = 0.10

Calculating the test statistic:

t = (86.8 - 93) / (14.6 / sqrt(18))

t = -6.2 / (14.6 / 4.24264)

t ≈ -2.677

The degrees of freedom for this test is n - 1 = 18 - 1 = 17.

Now, we need to determine the critical value for the t-distribution with 17 degrees of freedom and a one-tailed test at a significance level of 0.10. Consulting a t-table or using statistical software, the critical value is approximately -1.333.

Since the test statistic (t = -2.677) is less than the critical value (-1.333), we reject the null hypothesis.

F₁ ​= (0.252i^+0.436j^​)N

Similarly, the force on the 7.00μC charge by the −4.00−μC charge is

F₂​ ​= \(k_{e}\)q₁​q₃/​r² ​​r^

= [(8.99×10⁹N.m²/C²)(7.00×10^−6C)(−4.00×10^−6C)​×(cos60°i^−sin60°j^​)]/(0.500m)²

The vertex is (-3, 7) and the range of the function is [7, ∞).

The range of a function refers to the set of all possible output values (or dependent variable values) that the function can produce. In other words, it is the set of all possible y-values of a function.

To find the vertex and range of the function y = |x + 3| + 7, we can use the standard form of the absolute value function:

y = |x| + k, where k is the vertical shift.

By applying this to the given function, we can see that the vertex is at the point (-3,7) since the absolute value of (x + 3) is zero at x = -3. Therefore, the vertex is (-3, 7).

To find the range, we can notice that the absolute value of (x + 3) will always be non-negative, so the function will always have a minimum value of 7. Therefore, the range of the function is [7, ∞).
