The required equation of a line is y = 9/5 (4x - 12)

Given-

The point from which the line passes through is (3,2)

The slope of the given line m is -4/5.

Equation of the line

The linear equation of a line can be represented by a set of points on a graph using the equation of the line.

The standard form of the line passing through the point x₁, y₁

The slope m is given by,

m = (y - y₁) / (x - x₁)

Put the values of points and slope in the above equation, we get,

-4/5 = (y - 2) / (x - 3)

-4/5(x - 3) = y -2

-4x/5 + 12/5 = y - 2

-1/5 (4x - 12) + 2 = y

y = 9/5 (4x - 12)

The linear equation of a line can be represented by a set of points on a graph using the equation of the line. The following equation depicts a line that crosses (3, 2) and has a slope of -4/5: y = 9/5 (4x - 12)

The relative rate of population change after seven years from now is a) 1.7 % (rounded off to 1 decimal place) b) Yes, the relative rate of population change will reach 2.3% in 19.21 years

The function for population t years from now is P(t)= 2+ 1.2e^(0.04t)

a) relative rate of change of population

= P'(t) / P(t)

= (0+1.2e^(0.04t) * 0.04 )/ ( 2+ 1.2e^(.04t) )

= 0.048 e ^(0.04t) / (2 + 1.2e^(0.04t) )

Relative rate of change of population 7 years from now

= 0.048 e ^(0.04 * 7) / (2+ 1.2e^(0.04*7))

=0.0177 = 0.177 * 100 = 1.7 % per year (rounded off to one decimal place

b) For the relative rate of change to reach 2.3 %

P'(t) / P(t) = 2.3 % = 0.023

⇒(0+1.2e^(0.04t) * 0.04 )/ ( 2+ 1.2e^(0.04t) ) = 0.023

⇒0.048e ^(0.04t) = 0.046 + 0.0267e^(0.04t)

⇒e ^(0.04t) = 0.958 + 0.556e ^(0.04t)

⇒e ^(0.04t) ( 1 - 0.556) = 0.958

⇒e ^(0.04t) ( 0.444) = 0.958

⇒e ^(0.04t) = 2.157

⇒0.04t = ln(2.157)           (applying ln on both sides)

⇒t = 19.21 years

The relative rate of population change is 2.3% in 19.21 years

The volume of the resulting solid is 3,280.953 cm3.

The volume of the resulting solid is calculated by subtracting the volume of the inner sphere (the hole) from the volume of the outer sphere (the ball). The volume of a sphere is calculated by the formula V=4/3πr3. Therefore, the volume of the outer sphere is V1=4/3π(13)3=4,714.286 cm3. Similarly, the volume of the inner sphere is V2=4/3π(7)3=1,433.333 cm3. Subtracting V2 from V1 gives the volume of the resulting solid as V3=4,714.286 - 1,433.333=3,280.953 cm3. Therefore, the volume of the resulting solid is 3,280.953 cm3.

An implementation of the `Point` class in Java with a `distance` method:

public class Point {

   private double x;

   private double y;

   public Point(double x, double y) {

       this.x = x;

       this.y = y;

   }

   public double distance(Point target) {

       double deltaX = this.x - target.x;

       double deltaY = this.y - target.y;

       return Math.sqrt(deltaX * deltaX + deltaY * deltaY);

   }

   public static void main(String[] args) {

       Point p1 = new Point(2.5, 3.8);

       Point p2 = new Point(1.0, 4.2);

       double distance = p1.distance(p2);

       System.out.println("The distance between p1 and p2 is: " + distance);

   }

}

In this implementation, the `Point` class has private attributes `x` and `y` to store the coordinates. The constructor `Point(double x, double y)` is used to initialize the point with the given coordinates.

The `distance` method takes another `Point` object as a parameter and calculates the distance between the current point and the target point using the distance formula. It returns the computed distance.

In the `main` method, we create two `Point` objects `p1` and `p2` with different coordinates. We then call the `distance` method on `p1` with `p2` as the target point and print the result.

This allows you to test the `Point` class and verify the correctness of the `distance` method.

The correct hypotheses to be tested based on the given information are H₀: Pm - Pf = 0 vs. Hₐ: Pm - Pf < 0 (option c).

These hypotheses reflect the conjecture that men are more likely to work than women. In hypothesis testing, the null hypothesis (H₀) typically represents the assumption of no difference or no effect, while the alternative hypothesis (Hₐ) represents the claim or hypothesis we want to support.

In this case, the null hypothesis states that there is no difference between the proportions of male and female college students who worked last summer (Pm - Pf = 0). The alternative hypothesis states that the proportion of male college students who worked last summer is greater than the proportion of female college students who worked (Pm - Pf < 0).

By testing these hypotheses using appropriate statistical methods, we can determine if the observed data supports the claim that men are more likely to work than women or if there is no significant difference between the two proportions. The correct option is c.

The probability of selecting a sample of 20 children and having exactly 3 children who are from multiple births is approximately 0.214

To calculate the probability of selecting a sample with exactly 3 children who are from multiple births, we need to use the binomial distribution formula

P(X = k) = C(n, k) × p^k × (1 - p)^(n - k)

where

X is the random variable representing the number of children from multiple births in the sample

k is the number of children from multiple births we are interested in (in this case, k = 3)

n is the sample size (in this case, n = 20)

p is the probability of selecting a child from a multiple birth (let's assume this is 0.03, or 3%, based on some statistics for multiple births in some regions).

C(n, k) is the number of ways to choose k children from a sample of n children, which is given by the binomial coefficient

C(n, k) = n! / (k! × (n - k)!)

Plugging in the values, we get:

P(X = 3) = C(20, 3) × 0.03^3 × (1 - 0.03)^(20 - 3)

= (20! / (3! × 17!)) × 0.03^3 × 0.97^17

The standard deviation measures the spread of the data points around the mean, rather than the spread about a different value such as "x" as the center.

No, it is not true that the standard deviation of "s" measures spread about the mean "x" as the center.

The standard deviation is a measure of the dispersion or variability of a set of data points.

It quantifies how much the individual data points deviate from the mean.

In statistics, "s" typically represents the sample standard deviation, which measures the spread or variability of the sample data around its sample mean.

The sample standard deviation is calculated by taking the square root of the variance.

On the other hand, "x" typically represents the sample mean, which is the average of the data points in a sample.

Step-by-step explanation:

a) Rocky Mountain should order 200 tires each time it places an order.

b) The total cost of this policy is $17,160.

a) To determine how many tires Rocky Mountain should order each time, we need to consider the different price levels and find the point where it is most cost-effective to order. Let's analyze the three price levels:

If fewer than 200 tires are ordered: The purchase price is $25 per tire.

If 200 or more, but fewer than 8,000 tires are ordered: The purchase price is $17 per tire.

If 8,000 or more tires are ordered: The purchase price is $13 per tire.

Since the ordering cost is $35 per order, it is most cost-effective to order the maximum quantity that falls within the second price level, which is 200 tires.

b) To calculate the total cost of this policy, we need to consider the ordering cost and the holding cost. The holding cost is 40% of the purchase price per tire per year. Let's calculate the total cost:

Total holding cost = (Purchase price per tire * Quantity ordered * Holding cost rate) / 2 = (($17 * 10,000 * 0.4) / 2) + (($13 * 2,000 * 0.4) / 2) = $34,000 + $5,200 = $39,200

Total cost = Total ordering cost + Total holding cost = (Ordering cost per order * Number of orders) + Total holding cost = ($35 * (10,000 / 200)) + $39,200 = $1,750 + $39,200 = $40,950

Therefore, the total cost of this policy is $40,950.

Rocky Mountain Tire Center should order 200 tires each time it places an order, resulting in a total cost of $40,950 for this policy. This ordering quantity and cost analysis allows Rocky Mountain to make efficient and cost-effective decisions in managing their inventory.
