The probability that the sample mean will be within 5 points of the population mean is 0.95 or 95%

The Central Limit Theorem (CLT), a foundational idea in statistics, holds that, regardless of the underlying population distribution, the distribution of the sample means will be about normal given a big enough sample size. The CLT is crucial because it enables us to draw conclusions about a population based on a sample, even when the population is not normal.

According to the CLT, as the sample size grows, sample means will approach population means and their standard deviations will fall. The standard error, also known as the standard deviation of the sample means, is calculated by dividing the standard deviation of the population by the square root of the sample size.

According to the Question

The sample mean for a random sample of 100 individuals is most likely to be within 5 points of the population mean. The distribution and standard deviation of the population, however, would determine the precise likelihood. The standard error may be used to determine a confidence interval for the population mean if the population standard deviation is known. A 95% confidence interval is frequently used, which is equivalent to 1.96 standard deviations from the mean. In this instance, especially with a large sample size, there is a good likelihood that the sample mean will be within 5 points of the population mean.

Answer:

In Explanation

Step-by-step explanation:

The constant of proportionality is a value that relates two variables that have a proportionate relationship. It is often represented by the letter "k".

For example, if two variables x and y are directly proportional, their relationship can be represented by an equation of the form y = kx, where k is the constant of proportionality. In this equation, the value of k represents the ratio of y to x and it is constant, meaning that it does not change as the values of x or y change.

In physics, the constant of proportionality also appears in many mathematical models of natural phenomena, such as Hooke's law (F = km) which relates the force applied on an object (F) to its displacement (x) with a spring constant (k), and Ohm's law (V = IR) which relates the voltage (V) across a resistor to the current (I) flowing through it with a resistance constant (R).

The constant of proportionality can have different units of measure depending on the context and is used to make quantitative predictions about the relationship between the variables. In some cases, it can be used to determine the behaviour of a system or physical process.

Elle can buy maximum 0.6 liters of goat milk and 1.2 liters of cow's milk.

What System of linear inequalities?

A system of linear inequalities is similar to a system of linear equations, except that it is made up of inequalities rather than equations. To represent scenarios with various restrictions, systems of linear inequalities are utilized.

Let x be the number of liters of goat milk and y be the number of liters of cow's milk that Elle wants to buy. We know that:

x + y ≤ 80 (because Elle wants to spend at most Php80)

130x + 65y ≤ 80 (because each liter of goat milk costs Php130 and each liter of cow's milk costs Php65)

This is a system of linear inequalities, and the solution set is the set of all possible combinations of x and y that satisfy both inequalities.

The inequality 130x + 65y ≤ 80 represents a line in the plane, and the inequality x + y ≤ 80 represents a region that is "bounded" by this line.

The solution set for the inequalities are x <= 0.6 and y <= 1.2.

So, Elle can buy maximum 0.6 liters of goat milk and 1.2 liters of cow's milk.

Answer:

H (Height) = 3

Step-by-step explanation:

We have the formula A = 1/2(a+b)h

Let's identify all variables

A = 24

a = 9

b = 7

h = ?

Lets plug all that in:

24 = 1/2(9+7)h

9+7 = 16

24 = 1/2(16)h

Half of 16 is 8 so to simplify the rest...

24 = 8h

To get h alone we will divide both sides of the equation by 8

24/8 = h

24/8 = 3

Making H = 3

The dimensions of the new practice court is 45.5 feet by 29.5 feet.

The equations should be completed as 160 = 2W + 2L; W = L - 16

Mathematically, the perimeter of a rectangle can be calculated by using this mathematical expression;

P = 2(L + W) or P = 2L + 2W

Where:

Since the width of the rectangular lot is 16 feet less than the length, we have:

W = L - 16

Substituting the given parameters into the perimeter formula, we have;

160 = 2L + 2W

160 = 2(L - 16) + 2L

160 = 2L - 32 + 2L

160 = 4L - 32

4L = 182

L = 45.5 feet.

For the width, we have:

W = L - 16

W = 45.5 - 16

W = 29.5 feet.

An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value. The operation's arity is determined by the number of operands.

Addition (+) is the most important of the four operations because it is the foundation of all arithmetic. It is used in everyday life for basic calculations such as adding up a grocery bill or calculating the total cost of a purchase with tax. It is also used in more advanced mathematical concepts such as algebra and calculus.

Multiplication (x) is the second most important operation because it is used to find the total number of items in a group or the total area of a shape. It is also used in more advanced mathematical concepts such as solving equations and finding derivatives.

Subtraction (-) is the third most important operation because it is used to find the difference between two numbers. It is also used in more advanced mathematical concepts such as algebra and calculus.

Division (÷) is the least important of the four operations because it is a reverse operation of multiplication, which is more important and more frequently used. It is used to find the number of times one number is contained within another or the size of a group when the total size and number of groups is known.

The bottom of the ladder is 9 feet from the wall.

Using the Pythagorean Theorem, we can calculate the distance from the wall. The Pythagorean Theorem states that for a right triangle, the sum of the squares of the sides is equal to the square of the hypotenuse. In this case, the hypotenuse is 15 feet and the side adjacent to the wall is 12 feet.

The formula for the Pythagorean Theorem is a^2 + b^2 = c^2.

We can solve for the distance from the wall (a). a^2 = c^2 - b^2, so a^2 = 15^2 - 12^2, which equals a^2 = 225 - 144, so a^2 = 81. Taking the square root of both sides, a = 9 feet.

The ratio of servings to cones is 47:4.

In mathematics, a ratio is a way of comparing two or more values. It is usually represented as a fraction, with the values being separated by a colon (:). For example, if you have 7 apples and 4 oranges, the ratio of apples to oranges would be 7:4. This can also be written as 7/4 or 1.75. Ratios can also be written as a decimal or a percentage. Ratios can be used to compare quantities, sizes, or measurements in different units.

If the ratio of servings to cups is 7:47:47:4, that means for every 7 servings, there are 47 cups.

Since the servings came in either a cup or a cone, but not both, the ratio of servings to cones is the remaining portion of servings that are not accounted for in the ratio of servings to cups.

So, it's 7 servings + 47 cups = 47 servings + 4 cups.

Answer:

The dimensions of the rectangular tract of land with a perimeter of 44 kilometers and an area of 120 square kilometers are:

Length = 10 kilometers

Width = 12 kilometers

Explanation: To find the dimensions of a rectangular tract of land when its perimeter and area are known, you can use the formulas:

Perimeter = 2(length + width)

Area = length * width

We know that:

Perimeter = 44 kilometers

Area = 120 square kilometers

So, we can use these values to set up the following equation:

44 = 2(length + width)

And we can solve for length and width.

44 = 2(length + width)

22 = length + width

And now we know that the sum of the length and width of the rectangular tract is 22 kilometers.

Now we have to use the area formula:

Area = length * width

120 = length * width

We can use the value we have for the sum of the length and width to find either the length or the width of the rectangular tract.

For example, we can use the equation:

length = 22 - width

And substitute it into the area equation:

120 = (22 - width) * width

And then we can solve for width:

120 = 22 * width - width^2

width^2 - 22 * width + 120 = 0

We can use the quadratic formula to solve for width.

width = (22 +/- sqrt(22^2 - 4 * 1 * 120))/ 2

So,

width = (22 +/- sqrt(484 - 480))/ 2

width = (22 +/- sqrt(4))/ 2

width = (22 +/- 2)/ 2

width = (24)/ 2

width = 12

So, the width of the rectangular tract is 12 kilometers.

And we can use the equation:

length = 22 - width

to find the length

length = 22 - 12 = 10

So, the dimensions of the rectangular tract of land with a perimeter of 44 kilometers and an area of 120 square kilometers are:

Length = 10 kilometers

Width = 12 kilometers

The coordinates of the point that partitions the segment is given as :  (-3, 21)

To find the coordinates of the point on the directed line segment from (-9, 9) to (7, -7) that partitions the segment into a ratio of 3 to 5, we can use the concept of vector addition.

First, we can represent the directed line segment as a vector, with the initial point (-9, 9) being the tail, and the terminal point (7, -7) being the head. The vector representing the directed line segment is:

V = <7 - (-9), -7 - 9> = <16, -16>

To partition the segment into a ratio of 3 to 5, we can represent the partition point as a scalar multiple of the vector V:

P = (-9, 9) + (3/8)V = (-9, 9) + (3/8)(16, -16)

The scalar multiple 3/8 is used to get the partition point, it's calculated by dividing the desired ratio (3) by the sum of the ratio (3+5)

Then, we can find the x and y coordinates of the point P by applying the scalar multiple to the components of the vector:

P(x, y) = (-9, 9) + (3/8)(16, -16) = (-9, 9) + (3/8)(16, -16) = (-9 + 316/8, 9 - 3-16/8) = (-9 + 6, 9 + 12) = (-3, 21)

So the coordinates of the point on the directed line segment that partitions the segment into a ratio of 3 to 5 are (-3, 21).
