The value of x is either 3 or -5 based on the distance formula.

What is a co-ordinate system?

In pure mathematics, a coordinate system could be a system that uses one or additional numbers, or coordinates, to uniquely confirm the position of the points or different geometric components on a manifold like euclidean space.

Main body:

according to question

Given points A(-1,4) and B(x,7)

Also AB = 5 cm

Formula of distance = \(\sqrt{(y1-y2)^{2}+(x1 -x2)^{2} }\)

here by using points ,

5 = \(\sqrt{(x+1)^{2} +(7-4)^{2} }\)

taking square on both side ,'

25 = \((x+1)^{2} +3^{2}\)

25-9 = (x+1)²

16 = (x+1)²

taking square root on both sides,

x+1= ±4

x = 4-1 = 3                                  or              x = -4-1 = -5

Hence value of x is either 3 or -5.

ZT = 11

Step-by-step explanation:

Diagonals of a parallelogram bisects each other.

\( \therefore ZT = \frac {1}{2} \times VT\\\\

\therefore ZT = \frac {1}{2} \times 22\\\\

\therefore ZT = 11\\\\\)

First find the center, then graph all the points that are at a distance of R units from that center.

A circle of radius R is the set of all points that are at a distance R from a given point (the center of the circle).

So to graph it, we need to know these two things, radius and center.

Once we do, first we graph the center on the coordinate plane.

Once we find the center, we can find all the poiints that are at a distance of R units from our center, so we need to graph these. Once we do, we will have the graph of our circle on the coordinate plane.

Rick will have to wash the plates for three minutes.

By first figuring out the value of a single unit and then multiplying the number by that value, the unitary approach in mathematics can be used to determine the required value.

• The unitary technique can be used to determine how many kilometres can be covered with 2 litres of gasoline, for instance, if a car goes 80 km on 6 l of fuel.

He washed 4 dishes in 2 minutes, thus we need to calculate how long it would take Rick to wash 6 plates. 4 plates, according to the rule, equals 2 minutes. Applying the unitary approach 1 plate in 2/4 of a minute 1 plate Equals 12 minute. 3 minutes equals 6 plates (12 times 6.6 plates).

Explanation:

The line of best fit here is y = 6x+62

We started at (0,62) and go up 6 units and to the right 1 unit each time we move along this line.

If we tried something like x = 1, then,

y = 6x+62

y = 6*1+62

y = 6+62

y = 68

Meaning that someone spending 1 hour per week doing homework would lead to an estimated score of 68. This matches what the graph shows, and it helps confirm we have the correct regression line equation.

Let's now plug in x = 5

y = 6x+62

y = 6*5+62

y = 30+62

y = 92

Someone doing 5 hours of homework per week is estimated to get a score of about 92.

Answer:

C. Yes, there is an outlier at 110. This means that one person's age was 110, which is 25 years older than the next closest age.

Step-by-step explanation:

An outlier is a data point that sticks out like a sore thumb. It's so different from the rest of the data that it makes you wonder if it's a mistake or a miracle. One way to spot an outlier is to use the 1.5IQR rule, where IQR stands for interquartile range. The interquartile range is the gap between the third quartile (Q3) and the first quartile (Q1) of the data. The 1.5IQR rule says that any data point that is more than 1.5*IQR above Q3 or below Q1 is an outlier.

In this case, the first quartile (Q1) is 75, the third quartile (Q3) is 85, and the interquartile range (IQR) is 10. So, any data point that is more than 1.5*10 = 15 above 85 or below 75 is an outlier. The only data point that does this is 110, which is 25 above 85. That means 110 is an outlier.

What does this outlier mean in this situation? It means that one person who came to the senior center that afternoon was way older than the rest of the folks. The average age of the visitors was not changed by this outlier, since it was just one out of 12 data points. But, the outlier does mess up the range and the standard deviation of the data, making them bigger than they would be without the outlier.

The value of X from the given diagram of a hexagon would be = 13. That is option B.

A hexagon can be defined as the type of a polygon that has 6 sides with the sum of its exterior angle as 360°.

That is from the given diagram;

62+(4x+7)+(6x-5)+41+(3x+6)+(7x+11) = 360

Bring the like terms together;

62+41+7+6 -11-5+4x+6x+3x+7x = 360

100 + 20x = 360

20x = 260

X = 260/20

X = 13

Therefore the Value of X from the hexagon given above = 13. This value can be used to determine the various unknown values of the exterior angle of the hexagon.

The average monthly payment would be most affected by Mark's observation of one significantly lower payment. The reason is that the average is calculated by summing all the payments and dividing by the total number of payments, so any extreme values (such as the significantly lower payment) can have a substantial impact on the average value.

Step-by-step explanation:

The representation of D in the form D_x, D_y, where the x and y components are separated by a comma will be D[6.08,7.27]

Any vector oriented in two dimensions can be understood to have an impact in both directions. This implies that it may be divided into two halves. A component is a portion of a two-dimensional vector. The components of a vector assist to represent the vector's effect in a certain direction. The total impact of these two components is equivalent to the influence of the separate two-dimensional vectors. The two vector components can substitute the single two-dimensional vector.

Determine the x and y components for each vector A & B for vector A

Ax=sin (15) * 2=0.5176

Ay=cos (15) * 2=1.9318

for Vector B

Bx=cos (15) * 4=3.8637

By=sin (15)* 4=1.0352

The vector addition and scalar multiplication for x and y individually D=4.3 * A+B

Dx=4.3 *(sin (15) * 2)+cos (15) * 4

The actual question may be:

Express D in the form D_x, D_y, where the x and y components are separated by a comma using two significant figures.

Answer:

A. f(-x) = f(x)

Step-by-step explanation:

When plugged into a graph, we can see that the y value of -x is equal to x.

This means, that if we compare the y value of x=3 and x=-3, they will be the same on the graph.

A) The two possibilities for the x component are approximately +58.12 units and -58.12 units. B) The magnitude of the vector that, when added to the original one, would give a resultant vector that is 80.0 units long and points entirely in the +x direction is 0 units. c) The direction of the vector is approximately -42.29 degrees relative to the positive x-axis.

Part A:

Given that the magnitude of the vector is 80.0 units and the y component is -55.0 units, we can use the Pythagorean theorem to find the two possibilities for the x component.

The Pythagorean theorem states that the magnitude of a vector can be calculated as:

|V| = √(x² + y²)

Where |V| is the magnitude of the vector, x is the x component, and y is the y component.

In this case, we have:

|V| = 80.0 units

y = -55.0 units

Substituting these values into the equation, we can solve for x:

80.0 = √(x² + (-55.0)²)

Squaring both sides of the equation, we get:

6400.0 = x² + 3025.0

Rearranging the equation, we have:

x² = 6400.0 - 3025.0

x² = 3375.0

Taking the square root of both sides, we find:

x = ±√3375.0

Calculating the square root, we get two possibilities for the x component:

x₁ ≈ +58.12 units

x₂ ≈ -58.12 units

Part B:

Assuming the x component is known to be positive, we need to find the magnitude of the vector that, when added to the original one, would give a resultant vector that is 80.0 units long and points entirely in the +x direction.

To achieve this, we need to subtract the magnitude of the original vector (80.0 units) from the desired magnitude (80.0 units). Since the resultant vector points in the +x direction, the magnitude of the additional vector should be zero.

Therefore, the magnitude of the vector that, when added to the original one, would give a resultant vector that is 80.0 units long and points entirely in the +x direction is 0 units.

Part C:

The direction of the vector can be determined by using trigonometric functions. We can calculate the angle θ between the vector and the positive x-axis using the inverse tangent function:

θ = arctan(y / x)

Given that the y component is -55.0 units and the x component is +58.12 units (assuming positive x), we have:

θ = arctan(-55.0 / 58.12)

Calculating this angle, we find:

θ ≈ -42.29 degrees

The negative sign indicates that the vector points below the negative x-axis.

So, the direction of the vector is approximately -42.29 degrees relative to the positive x-axis.

Using the given percentage, we found that the total number of chocolate chip muffins sold is 80.

What is meant by percentage?

A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Frequently, it is indicated with the per cent sign, "%". If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word per cent means. A % is a number without dimensions and without a standard measurement. The value of "whole" in this relationship between portion and whole is always set at 100.

Given,

 the number of chocolate  chip muffins sold = 36

The 36 muffins is the 45% of the total muffins sold.

Let the total number of muffins sold be x.

Then using the given percentage, we find the total muffins sold.

Percentage = (required number of muffins sold/ total number sold) *100

45% = 36/x * 100

0.45 = 36/x

x = 36/0.45 = 80

Therefore using the given percentage, we found that the total number of chocolate chip muffins sold is 80.
