Answer:

The coordinates of S is \(( \frac{-3}{4}, \frac{1}{2})\)

Step-by-step explanation:

We are supposed to find the coordinates of point S

Point S is 0.75 units to the left

So, x coordinate of point S = -0.75 = \(\frac{-3}{4}\)

Now we are given that point S is 0.5 units up.

So, y coordinate of point S = 0.5 = \(\frac{1}{2}\)

So, The coordinates of S is \(( \frac{-3}{4}, \frac{1}{2})\)

So, Option A is true .

The simplified form of √72 + √32 + √18 is 10 + 3√2.

To simplify the expression √72 + √32 + √18, we need to simplify each square root separately and then combine like terms.

Step 1: Simplify √72:

We can break down 72 into its prime factors: 72 = 2 * 2 * 2 * 3 * 3. Using the property

√(a * b) = √a * √b, we have

√72 = √(2 * 2 * 2 * 3 * 3) = √(2² * 3²)

= 2 * 3

= 6.

Therefore, √72 simplifies to 6.

Step 2: Simplify √32:

We can break down 32 into its prime factors:

32 = 2 * 2 * 2 * 2 * 2. Using the same property as above, we have

√32 = √(2 * 2 * 2 * 2 * 2)

= √(2⁴)

= 2²

= 4.

Thus, √32 simplifies to 4.

Step 3: Simplify √18:

We can break down 18 into its prime factors:

18 = 2 * 3 * 3. Using the same property, we have

√18 = √(2 * 3 * 3)

= √(2 * 3²)

= √(2 * 3²)

= 3√2.

Step 4: Combine like terms:

Putting it all together,

√72 + √32 + √18

= 6 + 4 + 3√2

= 10 + 3√2.

Therefore, the simplified form of √72 + √32 + √18 is 10 + 3√2.

The last graph shows the relationship given in the table

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Slope = 11.50-8.5/4-2

Step-by-step explanation:

Given f(x) divided by (x - h) then the value of f(h) is the remainder, thus

f(6) = 2(6)³ - 9(6)² + 11

     = 2(216) - 9(36) + 11

     = 432 - 324 + 11

     = 119 ← remainder

Answer:

(18 + 36 + 27) = 9 x (2+4+3)

(88 + 66 + 22) = 22 x (4+3+1)

(36 + 96 + 12) = 12 x (3+8+1)

(126 + 28 + 14) = 14 x (9+2+1)

(54 + 81 + 27) = 27 x (2+3+1)

(16 + 28 + 48) = 4 x (4+7+12)

Step-by-step explanation:

The equations in the solution represent each expression as a multiple of a sum of whole numbers with no common factor.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

As per the given question, the required solution would be as:

(18 + 36 + 27) = 9 × (2+4+3)

This equation represents each expression as a multiple of a sum of whole numbers with no common factor.

Answer:

x = 3\(\sqrt{2}\) , y = \(\frac{3\sqrt{2} }{2}\)

Step-by-step explanation:

this is a 90- 45- 45 isosceles triangle with legs congruent , that is

y = \(\frac{3\sqrt{2} }{2}\)

using Pythagoras' identity in the right triangle

x² = ( \(\frac{3\sqrt{2} }{2}\) )² + y²

   = ( \(\frac{3\sqrt{2} }{2}\) )² + ( \(\frac{3\sqrt{2} }{2}\) )² = 9 + 9 = 18 ( take square root of both sides )

x = \(\sqrt{18}\) = \(\sqrt{9(2)}\) = \(\sqrt{9}\) × \(\sqrt{2}\) = 3\(\sqrt{2}\)

Variance and standard deviation are both measures of the dispersion or spread of a dataset, but they differ in terms of the unit of measurement.

Variance is the average of the squared differences between each data point and the mean of the dataset. It measures how far each data point is from the mean, squared, and then averages these squared differences. Variance is expressed in squared units, making it difficult to interpret in the original unit of measurement. For example, if we are measuring the heights of individuals in centimeters, the variance would be expressed in square centimeters.

Standard deviation, on the other hand, is the square root of the variance. It is a more commonly used measure because it is expressed in the same unit as the original data. Standard deviation represents the average distance of each data point from the mean. It provides a more intuitive understanding of the spread of the dataset. For example, if the standard deviation of a dataset of heights is 5 cm, it means that most heights in the dataset are within 5 cm of the mean height.

To illustrate the application of these measures, consider a dataset of test scores for two students: Student A and Student B.

If Student A has test scores of 80, 85, 90, and 95, and Student B has test scores of 70, 80, 90, and 100, we can calculate the variance and standard deviation for each student's scores.

The variance for Student A's scores might be 62.5, and the standard deviation would be approximately 7.91. For Student B, the variance might be 125 and the standard deviation would be approximately 11.18.

These measures help us understand how much the scores deviate from the mean, and how spread out the scores are within each dataset.

Step-by-step explanation:

1) remove the constant(number without variable) to do this, we must use the opposite operation(in our case, subtraction)

b) remove the coefficient by doing the opposite operation(division in our case)

x=-8

Answer:

z = 66

y = 120

Step-by-step explanation:

First, we can solve for z because it is supplementary to 114°.

114° + z° = 180°

-114°         -114°

z° = 66°

z = 66

Now, we can solve for y using the fact that the interior angles of a quadrilateral add to 360° (think about a rectangle: 4 x 90°).

We have to use the z value that we solved for earlier.

81° + 93° + y° + z° = 360°

↓ substituting in z-value

81° + 93° + y° + 66° = 360°

↓ combining like terms

240° + y° = 360°

-240°         -240°

y° = 120°

y = 120

Find the probability that a randomly selected customer will have to wait

a) less than 25 minutes

for x < 25 minutes

z = 25 - 30/10

z = -0.5

Probability value from Z-Table:

P(x<25) = 0.30854

b) more than 38 minutes

For x > 38 minutes

z = 38 - 30/10

z = 0.8

Probability value from Z-Table:

P(x<38) = 0.78814

P(x>38) = 1 - P(x<38) = 0.21186

c) between 26 and 32 minutes

For x = 26 minutes

z = 26 - 30/10

z = -0.4

Probability value from Z-Table:

P(x = 26) = 0.34458

For x = 32 minutes

z = 32 - 30/10

z = 0.2

Probability value from Z-Table:

P(x = 32) = 0.57926

The probability that a randomly selected customer will have to wait between 26 and 32 minutes is calculated as:

P(x = 32) - P(x = 26)

= 0.57926 - 0.34458

= 0.23468

The correct statement is: provided that the sample size is reasonably large (for any population).

The Central Limit Theorem states that, under certain conditions, the sampling distribution of the sample mean will be approximately normal, regardless of the shape of the population distribution.

These conditions include a random sample from the population and a sufficiently large sample size (typically, n > 30 is considered large enough).

Therefore, the Central Limit Theorem is important because it allows us to make inferences about the population mean using the normal distribution, even if we do not know the population distribution.

This is useful in many applications of statistics, including hypothesis testing, confidence intervals, and estimating population parameters

Therefore, the point (0, 2) can be considered a critical point of the given information.

In mathematics, coordinates are a set of numbers used to determine the position of a point on a particular plane or in space. The most common type of coordinate system is the Cartesian coordinate system, which uses a pair of numbers (x, y) to identify the position of a point in a 2-dimensional plane, and a set of three numbers (x, y, z) to identify the position of a point in a 3-dimensional space. Coordinates can also be used to describe the position and movement of objects in physics, engineering, and other fields.

Here,

None of the points (2, 0), (0, 3), (3, 0), (0, 0), and (5, 0) lie on the line passing through (0, 2) and (4, 0). However, the point (0, 2) lies on the y-axis, which is perpendicular to the line passing through (0, 2) and (4, 0).

Since the points on this graph represent a relationship between x- and y-values, the statement which is true about the relationship is that: 4. It cannot be proportional because a straight line through the points does not go through the origin.

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

In Mathematics, the graph of any proportional relationship is characterized by a straight line with the points passing through the origin (0, 0) because as the values on the x-axis (x-coordinate) increases or decreases, the values on the y-axis (y-coordinate) increases or decreases simultaneously.

In this context, we can reasonably infer and logically deduce that the relationship between x-values and y-values in this graph is not proportional.
