In Mathematics and Statistics, a frequency table can be used for the graphical representation of the frequencies or relative frequencies that are associated with a categorical variable or data set.

In a frequency distribution table, all classes must have the same class width. In this context, we would develop a grouped frequency table by using a class width of 10 as follows;

Interval            Frequency

10 − 19                   9

20 − 29                 7

30 − 39                 3

40 − 49                 4

50 − 59                 2

In conclusion, we can logically deduce that only histogram A correctly represents the ages of the people who ride the new roller coaster during a fifteen-minute period.

Of students in the sample, 90/200 fraction of the students were male.

Number of male students =90

Number of female students =110

So, total students = 90+110 =200

A fraction is a rational number that is not a whole number.

Fraction of students who were male = male students/ total students

Fraction of students who were male =90/200

So, 90/200 fraction of the students were male.

Hence, 90/200 fraction of the students were male.

The volume of the traffic pylon is 7.26 cubic feet.

To find the volume of the cone-shaped pylon, we'll use the formula for the volume of a cone, which is [tex]\( \frac{1}{3} \pi r^2 h \),[/tex]  where ( r ) is the radius of the base and ( h ) is the height.

Given that the height ( h ) of the pylon is 2.4 feet and the radius ( r ) is 1.7 feet, we can plug these values into the formula:

[tex]\[\text{Volume} = \frac{1}{3} \pi \times (1.7)^2 \times 2.4\][/tex]

Let's calculate this:

[tex]\[\text{Volume} \approx \frac{1}{3} \times 3.14159 \times (1.7)^2 \times 2.4\][/tex]

[tex]\[\text{Volume} \approx \frac{1}{3} \times 3.14159 \times 2.89 \times 2.4\][/tex]

[tex]\[\text{Volume} \approx \frac{1}{3} \times 3.14159 \times 6.936\][/tex]

[tex]\[\text{Volume} \approx \frac{1}{3} \times 21.78\][/tex]

[tex]\[\text{Volume} \approx 7.26 \text{ cubic feet}\][/tex]

So, the volume of the cone-shaped pylon is approximately 7.26 cubic feet.

Every second, the number of harmful bacteria remaining in the body decays by a factor of approximately .

To determine the rate of change in the number of harmful bacteria remaining in the body every second, we need to convert the time in the given function from minutes to seconds. The function provided is

⇒ [tex]H_{minute}[/tex](t) = 500,000,000 · [tex](0.2)^t[/tex].

A minute has 60 seconds, so we need to express the decay factor for a second. By letting t = [tex]t_{seconds}[/tex] ÷ 60, we can rewrite the function in terms of seconds:

⇒ [tex]H_{second}[/tex](t) = 500,000,000 · [tex](0.2)^\frac{t}{60}[/tex].

For every passing second, the decay factor is [tex](0.2)^\frac{1}{60}[/tex]. Using a calculator, we find:

⇒ [tex](0.2)^\frac{1}{60}[/tex] ≈ 0.98855,

rounded to two decimal places.

Therefore, every second, the number of harmful bacteria remaining in the body decays by a factor of approximately 0.99.

Complete question:

First of all we all should know about a geometric progression to solve this question.

A geometric progression is a series in which there is a first term a and all the next terms are calculated by multiplying the previous term by a common number r.

where a is known as first term and

r is known as common ratio.

In the question we are given a as 20 and we have to find out 2 terms after 20 and 4th term is given as 2500.

Formula for [tex]n^{th}[/tex] term in a geometric progression is:

[tex]a_{n} = a\times r^{n-1}[/tex]

Here [tex]a_{4}[/tex] = 2500

As per formula of [tex]n^{th}[/tex] term:

[tex]a\times r^{3} = 2500\\\Rightarrow 20 \times r^{3} =2500\\\Rightarrow r^{3} = 125\\\Rightarrow r = 5[/tex]

Now, 2nd term:

[tex]a_{2} = a \times r\\\Rightarrow a_{2} = 20 \times 5\\\Rightarrow a_{2} = 100[/tex]

Now, 3rd term:

[tex]a_{3} = a \times r^{2} \\\Rightarrow a_{3} = 20 \times 5^{2}\\\Rightarrow a_{3} = 500[/tex]

So, the two geometric means between 20 and 2500 are 100 and 500.

Final answer:

Two pumps working together will fill a tank in 12/7 hours, calculated by adding their rates of filling the tank and taking the inverse of the sum.

Explanation:

When two pumps are used together to fill a tank, the time it takes can be found by adding their rates of work and then finding the inverse of the sum. The first pump can fill the tank in 4 hours, which means its rate is 1/4 of the tank per hour. The second pump can fill the same tank in 3 hours, implying a rate of 1/3 of the tank per hour. When both pumps work together, their combined rate is (1/4 + 1/3) = (3/12 + 4/12) = 7/12 of the tank per hour.

To find the time taken to fill the tank jointly, we take the inverse of the combined rate: 1 / (7/12), which equals 12/7 hours. Therefore, using both pumps together, it will take 12/7 hours to fill the tank.

Step-by-step explanation:

[tex]\frac{1}{4}b+6=16[/tex]

Subtract 6 from both sides,

[tex]\frac{1}{4}b+6-6=16-6\\\\\frac{1}{4}b=10\\\\b=10*4\\b=40[/tex]

Answer:

40 beads

Step-by-step explanation:

We want to find how many beads, b are being used

1/4b+6=16

To do this, we have to solve for b, by getting b by itself.

First, move all the constants to the same side. Subtract 6 from both sides, since it is being added to 1/4b.

1/4b+6-6=16-6

1/4b=10

Next, divide both sides by 1/4, or multiply both sides by the reciprocal of 1/4.

To find the reciprocal, flip the numerator (top number) and denominator(bottom number)

1/4–> 4/1

4/1*1/4b=10*4/1

The 1/4 will cancel, leaving us with:

b=10*4/1

b=40

Answer: 40

Step-by-step explanation: When you're asked to solve for x in an equation, what you're really being asked to do is get x by itself on one side of the equation.

In this problem since 10 is being added to x, in order to get x by itself, we must subtract 10 from the left side of the equation and when we subtract 10 from the left side of the equation, remember that we must also subtract 10 from the right side of the equation.

So on the left, 10 - 10 cancels out and

on the right, 50 - 10 simplifies to 40.

So x = 40.

Answer:

x = 40

Step-by-step explanation:

To solve for x, we must get it by itself. To do this, we have to subtract 10 from the left and right side of the equation.

Equation: x + 10 - (10) = 50 - (10)

This will cancel out the 10 on the left side (as 10 - 10 = 0) of the equation and leave you with the answer, x = 40.

The most correct option is;

(B) 958.2 ft.²

Step-by-step explanation:

From the question, the dimension of each square = 3 ft.²

Therefore, the length of the sides of the square = √3 ft.

Based on the above dimensions, the dimension of the small semicircle is found by counting the number of square sides ti subtends as follows;

The dimension of the diameter of the small semicircle = 10·√3

Radius of the small semicircle = Diameter/2 = 10·√3/2 = 5·√3

Area of the small semicircle = (π·r²)/2 = (π×(5·√3)²)/2 = 117.81 ft.²

Similarly;

The dimension of the diameter of the large semicircle = 10·√3 + 2 × 6 × √3

∴ The dimension of the diameter of the large semicircle = 22·√3

Radius of the large semicircle = Diameter/2 = 22·√3/2 = 11·√3

Area of the large semicircle = (π·r²)/2 = (π×(11·√3)²)/2 = 570.2 ft.²

Area of rectangle = 11·√3 × 17·√3 = 561

Area, A of large semicircle cutting into the rectangle is found as follows;

[tex]A_{(segment \, of \, semicircle)} = \frac{1}{4} \times (\theta - sin\theta) \times r^2[/tex]

Where:

[tex]\theta = 2\times tan^{-1}( \frac{The \, number \, of \, vertical \, squrare \, sides \ cut \, by \ the \ large \, semicircle}{The \, number \, of \, horizontal \, squrare \, sides \ cut \, by \ the \ large \, semicircle} )[/tex]

[tex]\therefore \theta = 2\times tan^{-1}( \frac{10\cdot \sqrt{3} }{5\cdot \sqrt{3}} ) = 2.214[/tex]

Hence;

[tex]A_{(segment \, of \, semicircle)} = \frac{1}{4} \times (2.214 - sin2.214) \times (11\cdot\sqrt{3} )^2 = 128.3 \, ft^2[/tex]

Therefore; t

The area covered by the pavers = 561 - 128.3 + 570.2 - 117.81 = 885.19 ft²

Therefor, the most correct option is (B) 958.2 ft.².
