The term that best describes the distribution is uniform.

The distribution shown in the image appears to be uniform. The bars are relatively similar in height, indicating that all outcomes are equally likely or nearly so.

A distribution where most of the data points are concentrated on the right, with the tail extending to the left is said to be skewed. While A distribution where most of the data points are concentrated on the left, with the tail extending to the right is said to be skewed right. A symmetrical, bell-shaped distribution where most data points are concentrated around the mean, with fewer points as you move away from the center. is said to be normal.

Therefore, the term uniform best describes the given distribution in the image.

Using the Pythagorean theorem the formula would look:

[tex]c^2=b^2+a^2\Longrightarrow3.4^2=3^2+a^2[/tex]

Now just solve for a.

[tex]a^2=3.4^2-3.0^2\Longrightarrow a=\sqrt{3.4^2-3.0^2} \\

a=\sqrt{11.56-9}=\sqrt{2.56}=\boxed{1.6}

Answer:

About 6400

Step-by-step explanation:

Round all values: 316 --> 320, 4.03 --> 4, 0.198 --> 0.2

Expression: 320*4/0.2

Multiply: 320*4 = 1280, 1280/0.2

Divide: 2180/0.2 = 6400

316 times 4.03 equals 1273.48 then divide the product by 0.198 and you should get 6431.71717 and could round to 6432. sorry if this is wrong but have a wonderful day

ANSWER

139°

EXPLANATION

One of the interior angle properties of a parallelogram is that adjacent interior angles are supplementary.

This means that, the adjacent interior angles add up to 180°.

Answer:

The distance between the center and the foci is √13 ≅ 3.6 units

Step-by-step explanation:

* Lets revise the equation of the ellipse

- The standard form of the equation of an ellipse with center

  (0 ,  0) and major axis parallel to the x-axis is

x²/a² + y²/b² = 1

# a  >  b

- The length of the major axis is 2a

- The coordinates of the vertices are  (± a , 0)

- The length of the minor axis is 2b

- The coordinates of the co-vertices are (0 , ± b)

- The coordinates of the foci are  (± c , 0), where c² =  a² −  b²

* Lets solve the problem

∵ The equation is x²/49 + y²/36 = 1

∴ a² = 49

∴ b² = 36

∵ The coordinates of the foci are (± c  , 0)

∵  c² = a² − b²

∴ c² = 49 - 36 = 13 ⇒ take square root for both sides

∴ c = ± √13

∴ The foci are (√13 , 0) and (-√13 , 0)

∵ The center is (0 , 0)

∴ The distance between the center and the foci is c - 0 = c or

   0 - (-c) = c

∴ The distance between the center and the foci = √13 - 0 = √13 units

* The distance between the center and the foci is √13 ≅ 3.6 units

The distance of the foci from the center of the ellipse given by the equation [tex]x^{2/49} + y^{2/36}[/tex] = 1 is approximately 3.61 units.

To find the distance of the foci from the center of the ellipse given by the equation  [tex]x^{2/49} + y^{2/36}[/tex] = 1, we use the formula for the focal distance in an ellipse: c = √(a² - b²).

Here, a² is the larger denominator, which is 49, and b² is the smaller denominator, which is 36. Therefore:

Now, calculate the focal distance:

c = √(a² - b²) = √(49 - 36) = √(13) ≈ 3.61

Thus, the foci are approximately 3.61 units away from the center of the ellipse.

Answer:

[tex]cos(C) =\frac{40}{41}\\\\cos(C)=0.976[/tex]

Step-by-step explanation:

To find the [tex]cos (C)[/tex] we must use the cosine theorem.

The cosine theorem says that:

[tex]c^2 = a^2 +b^2 -2abcos(C)[/tex]

In this case:

[tex]c=AB = 9[/tex]

[tex]b=CA = 41[/tex]

[tex]a=BC = 40[/tex]

So

[tex]9^2 = 40^2 +41^2 -2(40)*(41)cos(C)[/tex]

[tex]9^2- 40^2- 41^2 =-2(40)*(41)cos(C)[/tex]

[tex]cos(C) = -\frac{9^2- 40^2- 41^2}{2(40)*(41)}[/tex]

[tex]cos(C) =\frac{40}{41}\\\\cos(C)=0.976[/tex]

Answer:

The answer is 525

Answer:

Option B. 525 students.

Step-by-step explanation:

The school enrollment for Oakwood Elementary is shown in the graph.

The given graph is representing a linear function. So we will form the function first to calculate the enrollment in 2012.

Equation of the given line in the graph will be in the form of y = mx + c

where m is the slope and c = y- intercept

y-intercept = 300

this line passes through two ordered pairs (0, 300) and (1, 325)

Now the slope m = [tex]\frac{y-y'}{x-x'}[/tex]

m = [tex]\frac{325-300}{1-0}=25[/tex]

Therefore, equation representing the situation will be y = 25x + 300

Now we will put the value of x = year 2012 - year 2003 = 9 years

y = 25×9 + 300

y = 225 + 300

y = 525

Option B. 525 is the correct option.

Answer:

always increasing

Step-by-step explanation:

When you look at the graph from left to right on the x-axis the y-axis is always increasing in value.

The graph in question is a line graph, used to show correlations between two variables on a horizontal and vertical axis. Other graph types include bar graphs, for comparing different categories of data, and pie charts, for representing parts of a whole. The third exam vs final exam graph demonstrates a good model of linearity with little deviation.

The description best fitting the graph in this instance is that of a line graph. Line graphs are used to show the correlation between two variables, one on the horizontal axis and one on the vertical axis. They are most appropriate when trying to communicate trends, such as increases, decreases, or consistency over a period of time.

Another type of graph is a bar graph, which is most effective when comparing different categories of data. For example, comparing the amount of rainfall each month can be appropriately represented using a bar graph. Finally, a pie chart displays proportional relationships in the data and is best used when representing parts of a whole, such as voters' preferences in an election.

Referring back to the graph about the third and final exams, it could be said that the line of best fit models the data well, where there appears to be little deviation from the line. By analyzing the graphs carefully, it is possible to draw meaningful conclusions and compare data accurately.

Answer:

C

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Given x² + y² + 4x - 10y + 20 = 0

Collect x and y terms and subtract 20 from both sides. that is

x² + 4x + y² - 10y = - 20

To obtain standard form use the method of completing the square

add ( half the coefficient of the x/y term )² to both sides

x² + 2(2)x + 4 + y² + 2(- 5)y + 25 = - 20 + 4 + 25

(x + 2)² + (y - 5)² = 9 ← in standard form

with centre = (- 2, 5) and r = [tex]\sqrt{9}[/tex] = 3 → C

By rearranging the given equation to match the standard form of circle equation, we can determine the center of the circle to be (-2,5), and the radius to be 3.

The equation provided can be rewritten in the form (x - h)² + (y - k)² = r², wherein (h, k) denote the center coordinates of the circle, and r is the radius. To arrange it in this form, we group terms to complete the square for both x and y:

x² + 4x + y² - 10y = -20

⇒ (x² + 4x + 4) -4 + (y² - 10y + 25) - 25 = -20

⇒ (x + 2)² + (y - 5)² = 9

With this, we can identify the center of the circle to be at point (-2,5), and the radius is the square root of 9 which equals to 3. Hence, the correct answer is option C.

Step-by-step explanation:

Paralle lines have the same slope.

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

We have

[tex]5y+9=-2x[/tex]

Convert to the slope-intercept form:

[tex]5y+9=-2x[/tex]           subtract 9 from both sides

[tex]5y=-2x-9[/tex]         divide both sides by 5

[tex]y=-\dfrac{2}{5}x-\dfrac{9}{5}\to m=-\dfrac{2}{5}[/tex]

Each of the answers to choose from is not the line equation sought.

The equation:

[tex]y=-\dfrac{2}{5}x+b[/tex] where b is any real number.

Parallel lines share the same slope. The slope of the given line is -2/5, so none of the provided options are correct as none have this slope.

To find the equation of a line that is parallel to another, it's important to know that parallel lines have the same slope. So firstly, we need to find the slope of the given equation. Starting with 5y + 9 = -2x, we will rearrange this into slope-intercept form (y = mx + b), where 'm' is slope and 'b' is y-intercept.

So, the slope of the given line is -2/5. This means a parallel line will also have the slope -2/5. Therefore, neither [1] y=-2x +3 nor [2] y = 2x + 1, [3] y = x+4 and [4] y=-x-1 can be parallel to the given line because all of them have different slopes not equal to -2/5.

Answer:

The rectangular coordinates of the point are (3/2 , √3/2)

Step-by-step explanation:

* Lets study how to change from polar form to rectangular coordinates

- To convert from polar form (r , Ф) to rectangular coordinates (x , y)

 use these rules

# x = r cos Ф

# y = r sin Ф

* Now lets solve the problem

∵ The point in the rectangular coordinates is (√3 , π/6)

∴ r = √3 and Ф = π/6

- Lets find the x-coordinates

∵ x = r cos Ф

∵ r = √3

∵ Ф = π/6

∴ x = √3 cos π/6

∵ cos π/6 = √3/2

∴ x = √3 (√3/2) = 3/2

* The x-coordinate of the point is 3/2

- Lets find the y-coordinates

∵ y = r sin Ф

∵ r = √3

∵ Ф = π/6

∴ y = √3 sin π/6

∵ sin π/6 = 1/2

∴ y = √3 (1/2) = √3/2

* The y-coordinate of the point is √3/2

∴ The rectangular coordinates of the point are (3/2 , √3/2)

Step-by-step explanation:

Answer:

The minimum of h(x) is farther left and down from the minimums of f(x) and g(x) ⇒ answer 4

Step-by-step explanation:

* Lets revise the meaning of the minimum of the function

- The minimum of a function is the lowest point of a vertex

- The minimum value is the y-coordinate of the lowest point

* Now lets solve the problem

∵ f(x) = √x

- The domain of the function is all the real numbers ≥ 0, because

 there is no square root for negative numbers

- We will use the first value of x to find the range of the function

∵ x = 0 ⇒ first value of the domain

∴ f(0) = √0  = 0

∴ The minimum of f(x) is point (0 , 0)

∵ g(x) = √(x - 3) + 1

- Lets find the domain of the function

∵ x - 3 ≥ 0 ⇒ add 3 for both sides

∴ x ≥ 3

∴ The domain of the function is all real values of x ≥ 3

- We will use the first value of x to find the range of the function

∵ x = 3 ⇒ the first value of the domain

∴ g(3) = √(3 - 3) + 1 = 0 + 1 = 1

∴ The minimum of g(x) is point (3 , 1)

∵ h(x) = √(x + 1) - 2

- Lets find the domain of the function

∵ x + 1 ≥ 0 ⇒ subtract 1 for both sides

∴ x ≥ -1

∴ The domain of the function is all real values of x ≥ -1

- We will use the first value of x to find the range of the function

∵ x = -1 ⇒ the first value of the domain

∴ h(-1) = √(-1 + 1) - 2 = 0 -  = -2

∴ The minimum of h(x) is point (-1 , -2)

* To find the correct answer look to the minimum points of the

 functions (0 , 0) , (3 , 1) , (-1 , -2)

- The minimum of f(x) lies on the origin

- The minimum of g(x) lies in the 1st quadrant

- The minimum of h(x) lies in the 3rd quadrant

∴ The minimum of h(x) is farther left and down from the minimums

   of f(x) and g(x)

- Look to the attached graph to more understand

- The red curve is f(x)

- The blue curve is g(x)

- The green curve is h(x)

Final answer:

The minimums of f(x) and g(x) are in the first quadrant, and h(x) is in the fourth quadrant, making the minimum of h(x) farther right and up from the minimums of f(x) and g(x).

Explanation:

To compare the relative locations of the minimums of the functions f(x) = √x, g(x) = √x - 3 + 1, and h(x) = √x + 1 - 2, we need to consider how transformations affect the graph of the square root function.

The function f(x) is the parent square root function. Its minimum is at the origin (0,0), which is in the first quadrant.

The function g(x) is a horizontal translation 3 units to the right and a vertical translation 1 unit up from the function f(x). Hence, its minimum would also be in the first quadrant.

The function h(x) is a horizontal translation 1 unit to the right and a vertical translation 2 units down from f(x), which places its minimum in the fourth quadrant because the downward translation moves it below the x-axis.

Thus, the correct statement is: 3. The minimum of h(x) is farther right and up from the minimums of f(x) and g(x).

Step-by-step explanation:

The pair of equations has one solution and the solution is (30/11, 20/11).

The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

The coordinates on one line are (2, 6) and (5, 0)

Here, m=(0-6)/(5-2)

= -2

Substitute m=-2 and (2, 6) in y=mx+c, we get

6=-2(2)+c

c=10

So, the equation of a line is y=-2x+10 -----(i)

The coordinates on another line are (0, 2) and (6, 6)

Here, m= (6-2)/(6-0)

= 2/3

Substitute m=2/3 and (0, 2) in y=mx+c, we get

2=2/3(0)+c

c=0

So, the equation is y=2/3 x -----(ii)

Substitute equation (ii) in (i), we get

2/3 x=-2x+10

2x/3 +3x =10

11x=30

x=30/11

Substitute x=30/11 in equation (ii), we get

y =2/3 × 30/11

y= 20/11

So, the solution is (30/11, 20/11)

Therefore, the pair of equations has one solution and the solution is (30/11, 20/11).
