Answer:

100π

Step-by-step explanation:

The formula for the surface area of a sphere is SA = 4πr^2, where r is the radius of the sphere and SA stands for surface area. We are given that the radius is 5, so if we plug this into the formula, we get that SA = 4π*(5)^2, or SA = 4 * 25 * π. If we solve it out, we get 100π. If the software wants you to let π be 3.14 and evaluate, you will get approximately 314. I hope this helps

Explanation:

The y coordinates are identical, so we just need to focus on the x coordinates.

Going from 0 to -3 is a distance of 3 units. Drawing out a number line might help.

Or we could apply subtraction and absolute value

|x1-x2| = |0-(-3)| = |0+3| = |3| = 3

which is the same as

|x2-x1| = |-3-0| = |-3| = 3

The absolute value is to ensure the result is never negative. Distance is never negative.

Side note: if the y coordinates weren't the same, then we'd have to use either the pythagorean theorem or the distance formula.

To find the equation of the straight line passing through the point \(P(-2, 3)\) and the origin O, we can use the point-slope form of a linear equation. The equation of the line is \(y = (-3/2)x\).

The point-slope form of a linear equation is given by \(y - y_1= m(x - x_1)\), where \((x_1, y_1)\) is a point on the line and m is the slope of the line. Given that the point \(P(-2, 3)\) lies on the line and O is the origin, we can substitute the coordinates of P into the point-slope form. Therefore, we have \(y - 3 = m(x - (-2))\).

To find the slope of the line, we can use the formula \(m = (y_2- y_1) / (x_2 - x_1)\), where \((x_1, y_1)\) and \((x_2, y_2)\) are two points on the line. In this case, we can use the coordinates of P and O to calculate the slope as \(m = (3 - 0) / (-2 - 0) = -3/2\).

Substituting the values of m and the coordinates of P into the point-slope form, we get \(y - 3 = (-3/2)(x + 2)\). Simplifying this equation gives us \(y = (-3/2)x - 3 + 3\), which further simplifies to \(y = (-3/2)x\). Therefore, the equation of the straight line passing through the point \(P(-2, 3)\) and the origin O is \(y = (-3/2)x\).

Complete question :

There is a competition at the local movie theater for free movie tickets. You must guess all four employees' ages given a few clues. The first clue is when their ages are added together the sum is 106. Kirk is 2 times the quantity of ten years less than the manager's age, Brian is 12 years younger than twice the manager's age, ,and Matt is 6 years older than ½ the manager's age. What are all four of their ages? Be sure to show set up equation work and answer

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following clue :

Let manager's age = m

Kirk's age = k

Brian's age = b

Matt's age = a

Sum of their ages = 106

k = 2(m - 10) = 2m - 20

b = 2m - 12

a = 0.5m + 6

k + b + a + m = 106

Express all their ages in terms of m

2m - 20 + 2m - 12 + 0.5m + 6 + m = 106

5.5m - 20 - 12 + 6 = 106

5.5m - 26 = 106

5.5m = 106 + 26

5.5m = 132

m = 132 / 5.5

m = 24

Manager's age = 24 years

kirk = 2(24 - 10) = 2(14) = 28 years

Brian = 2(24) - 12 = 48 - 12 = 36 years

Matt = 0.5(24) + 6 = 12 + 6 = 18 years

Answer:

9 mph

Step-by-step explanation:

d = rt     (distance = rate x time)

Paul rate:  j + 3

Jake rate: j

Paul time:  8 hr

Jake time:  12 hr

12j = 8(j + 3)

12j = 8j + 24

4j = 24

j = 24/4 = 6

Paul rate = j + 3 = 6 + 3 = 9 mph

If the supervisor increases the sample size to 600 residents, the estimated percentage of residents would become more accurate. A larger sample size provides a better representation of the population, thus reducing the potential for sampling error. In other words, a larger sample size means that the percentage of residents obtained from the sample would be more representative of the percentage of residents in the population.

For example, if the initial sample size was 100 residents, and the estimated percentage of a certain characteristic was 50%, there is a higher likelihood that this percentage may not accurately represent the true percentage of the population. However, if the sample size is increased to 600 residents, the estimated percentage would likely be closer to the true percentage of the population.

Overall, increasing the sample size allows for more precise estimates of population characteristics and reduces the potential for errors in generalizing sample results to the entire population.

Darcy gave her nail technician a $5.10 tip.

Tip Amount = $5.10

The tip was 6% of the cost of the manicure.

b be the cost of the manicure

So,

6% of cost of the manicure= Tip Amount

6% of b = 5.10

Equation of the cost is :

The equation is : 0.06b = 5.10

(a) The family of all solutions to Ax - b can be represented as x = x' + N(A). (b) A solution to Ax = b in part (a) with x = 5 is Ax = 0.

To find the family of all solutions to the equation Ax - b and a specific solution with x = 5.

(a) We know that Ax - b has the given solution x' = [10, 10, 0, 0]. This solution is also referred to as a particular solution. To find the family of all solutions, we need to find the general solution by adding the particular solution to the null space of matrix A. The null space contains all the solutions to the equation Ax = 0. Let's denote the null space vectors as N(A).

After finding the appropriate combination of null space vectors, add it to the particular solution x' to obtain the required solution with x = 5.

(b) To find a solution with x = 5, we need to find a suitable combination of vectors in the null space N(A) that, when added to the particular solution x', results in a new vector whose first component is 5. Keep in mind that the null space vectors are obtained from the equation Ax = 0, and their linear combinations represent the possible transformations of the particular solution.

Please note that without the specific matrix A and vector b, it's impossible to provide exact solutions. However, the method described above should guide you in solving this type of problem.

The amount of sugar imported by the U.S. in a day is a continuous random variable.

A random variable is a numeric value that is determined by the outcome of a random experiment. In other words, a random variable is a variable whose value varies from one trial of the experiment to the next. A random variable is classified as either a discrete or a continuous variable.

A discrete random variable is a random variable that takes on only discrete numerical values. For instance, the number of children in a family is a random variable that can only take on the values 0, 1, 2, 3, and so on.

A continuous random variable is a random variable that takes on any value within a certain range. Height, weight, and temperature are all examples of continuous random variables.

The amount of sugar imported by the United States in a day is a continuous random variable because it can take on any value within a range, i.e., it can be any value from 0 to infinity, and it can also take on decimal values.

Therefore, the correct answer is that it is a continuous random variable.

Step-by-step explanation:

The area of a rhombus can be found by multiplying the length of one of its sides by the height of a perpendicular line from the center to a side.

The height of the rhombus is the distance from the center of the rhombus to one of its sides, perpendicular to that side.

The formula for the area of a rhombus can be written as A = s*h, where A is the area, s is the length of one of the sides of the rhombus, and h is the height of the rhombus.

It's important to note that this method of finding the area of a rhombus without diagonals can only be used when the rhombus is a regular polygon, a polygon with all sides and angles congruent. When the rhombus is not a regular polygon, then you can find the area by using the diagonals.

Additionally, it's important to mention that a rhombus can be defined as a parallelogram with all sides congruent or a square with its angles not 90 degrees.

The Second Law of Probability states that the chance of combined events occurring is determined by the product of the chances of each separate event occurring.

The Second Law of Probability, also known as the Multiplication Rule, describes the relationship between the probability of separate events and the probability of combined events. According to this rule, if we have two or more independent events, the probability of both events occurring together is found by multiplying the probabilities of each individual event. This can be extended to more than two events by continuing to multiply the probabilities.

For example, if we have Event A with a probability of P(A) and Event B with a probability of P(B), the probability of both events A and B occurring simultaneously is given by P(A and B) = P(A) * P(B). This rule applies to any number of independent events.

The Second Law of Probability allows us to calculate the probability of complex events by breaking them down into separate, independent components. It provides a fundamental principle for determining the likelihood of combined events based on the probabilities of their individual occurrences.
