One of the primary goals of creating a frequency distribution for quantitative data is to properly represent the data as a whole. As a result, it is correct, as it accurately depicts the data as a whole.

Frequencies are organized into frequency distributions, which are visual displays, to make the information easier to understand. A frequency distribution can display absolute or relative frequencies, such as ratios or percentages. A frequency distribution can be represented by a graph or a frequency table. A frequency distribution can show both the exact number of observations and the proportion of observations that fall within each range. In the latter case, the distribution is referred to as a relative frequency distribution. The frequency of observation is the number of times it appears in the data. For example, the frequency of the number 9 in the following list of numbers is 5. (Because it happens five times). 1, 2, 3, 4, 6, 9, 9, 8, 5, 1, 1, 9

Answer:

4 pizzas

Step-by-step explanation:

Equation:

12x + 7 = 55

12x = 55 - 7

12x = 48

x = 4

The solution of the expression will be 3, -2, and -22 respectively.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the expressions are:-

2x²−3x−2 if x is less than or equal to -1

E = 2x²−3x−2

E = 2 (-1) ² - 3 x -1 -2

E = 2 + 3 - 2

E = 3

E = −x²+2x+1 if -1

E = -(-1)² + 2 x -1 + 1

E = -1 - 2 + 1

E = -2

E = −2x²−x−1

E = -2 ( 3 )² - 3 - 1

E = -18 - 3 - 1

E = -22

Answer: 3/5

Step-by-step explanation:

A=a+b/2h

Since the bottom width = 4 and the top length =2 and the length = 5

2+4=6

2(5)=10

so 6/10 = 3/5

We get (18 / 230) * 100 = 7.8260869565%. Rounded to the nearest tenth of a percent, the percentage is approximately 6.5%.

To calculate the percentage of racers who did not complete the marathon, we need to find the total number of racers who did not complete the race and divide it by the total number of racers who started the marathon. In this case, the total number of racers who did not complete the race is the sum of those who gave up (14) and those who were disqualified (4), which is 18. The total number of racers who started the marathon is given as 230.

Using the formula: (Number of racers who did not complete the race / Total number of racers who started the marathon) * 100, we can calculate the percentage. Plugging in the values, we get (18 / 230) * 100 = 7.8260869565%. Rounded to the nearest tenth of a percent, the percentage is approximately 6.5%.

The vertical angle between an object's direction and either north or another object is known as a bearing or azimuth in navigation. You can specify the angle value in a number of different angular units, including degrees, mils, and grad.

Angles are measured in comportments clockwise from north.

The direction of north must be identified before taking a bearing measurement.

The factors of the quadratic function whose graph is given are (-x -1) and ( x-5).

Factor of a quadratic equation is any monomial or binomial which divides the quadratic equation without leaving any remainder.

Factoring a quadratic equation can be defined as the process of breaking the equation into the product of its factors.

The solutions of a quadratic equation represent the values of x that make the equation true. And the solutions to any equation are the x-intercepts of that equation.

According to the given question

We have a graph of a quadratic equation and x intercepts -1 and -5.

⇒ we have two points (-1,0) and (-5,0)

⇒ -1 and -5 will be the solution of the quadratic function.

⇒ x = -1  and x = -5

⇒ x+ 1= 0 and x + 5 = 0

or -x -1 = 0 and x+5 = 0

Therefore, the factors of the quadratic function whose graph is given are (-x -1) and ( x-5).

The sloth speed of running is 10/3 meters per minute

Distance travelled = 1/3 meters

Time taken to travel the distance = 1/10 minute

The formula for speed is given:

The distance travelled in a unit of time is called speed. It refers to a thing's rate of movement. The scalar quantity known as speed is the velocity vector's magnitude. It has no clear direction. A faster rate of movement is indicated by a higher speed. It is travelling more slowly if the speed is lower.

Speed = Distance/ Time

Speed of the sloth = (1/3)/(1/10)

The maximum value of the sine function is 1, the angle corresponding to sin^(-1)(1) is π/2 or 90 degrees.

The principal value of sin^(-1)(1) is π/2 or 90 degrees.

The function sin^(-1)(x), also known as arcsin(x) or inverse sine, represents the angle whose sine is equal to x. In this case, we are looking for the angle whose sine is 1.

Since the sine function oscillates between -1 and 1, the angle corresponding to sin^(-1)(1) is the maximum value where the sine is equal to 1.

This occurs at π/2 or 90 degrees, making it the principal value for sin^(-1)(1).

Step-by-step explanation:

To find the volume of the post after the hole has been drilled, we need to subtract the volume of the cylindrical hole from the volume of the rectangular prism.

The volume of a rectangular prism is given by the formula:

V_prism = length * width * height

In this case, the length (L) is 10 cm, the width (W) is 7 cm, and the height (H) is 26 cm. Therefore, the volume of the rectangular prism is:

V_prism = 10 cm * 7 cm * 26 cm = 1820 cm³

The volume of a cylinder is given by the formula:

V_cylinder = π * r^2 * h

We are given the circumference of the cylindrical hole, which is 4π cm. The circumference formula is:

C = 2πr, where C is the circumference and r is the radius of the cylinder.

Solving for the radius (r):

4π = 2πr

r = 2 cm

Since the height (h) of the cylindrical hole is not given, we'll assume it is equal to the height of the rectangular prism, which is 26 cm.

Substituting the values into the volume formula, we get:

V_cylinder = π * (2 cm)^2 * 26 cm = 208π cm³

Now, we can find the volume of the post after the hole has been drilled by subtracting the volume of the cylindrical hole from the volume of the rectangular prism:

V_post = V_prism - V_cylinder = 1820 cm³ - 208π cm³

To round the answer to the nearest tenth, we'll approximate π as 3.14:

V_post ≈ 1820 cm³ - 208 * 3.14 cm³ ≈ 1820 cm³ - 653.12 cm³ ≈ 1166.88 cm³

Therefore, the volume of the post after the hole has been drilled is approximately 1166.88 cm³.

The equation of a line that passes through the point (1,-5) with slope -1 is y = -x - 4.

Given:

(1,-5) with slope m = -1

The standard slope intercept form is y = mx + c.

substitute m = -1 and (1,-5)

-5 = -1(1) + c

-5 = -1 + c

c = -4.

y = mx + c

y = -1(x) + (-4)

y = -x - 4.

Therefore the equation of a line that passes through the point (1,-5) with slope -1 is y = -x - 4.

Step-by-step explanation:

The height of the tower is: 274.7m

To find the height of the tower, we will use the tangent trigonometric function.

The tangent function relates the angle of elevation to the ratio of the opposite side (height of the tower) to the adjacent side (distance from the observer to the tower).

In this case, the angle of elevation is 70°, and the distance from the observer to the tower is 100 meters.

The formula we will use is:

tan(θ) = opposite / adjacent

tan(70°) = height / 100m

To calculate the height, we will rearrange the formula:

height = 100m * tan(70°)

Using a calculator, we find that tan(70°) ≈ 2.747.

Therefore, the height of the tower is: 274.7m

height ≈ 100m * 2.747 ≈ 274.7m
