The volume of the cylinder is approximately 1413.7 cubic centimeters.

The formula for the volume of a cylinder is V = πr²h, where r is the radius of the base and h is the height or length of the cylinder.

Since the base of the cylinder has a diameter of 9cm, the radius is half of that, or r = 4.5cm.

The length of the cylinder is given as 20cm.

Therefore, the volume of the cylinder is:

V = πr²h

= π(4.5)²(20)

= 1413.72 cubic centimeters (rounded to 1 decimal place)

Thus, the volume of the cylinder is approximately 1413.7 cubic centimeters.

The probability that a randomly chosen physical therapist does not use the gym membership given that they bring their lunch to work is 2/3, in simplest form.

The table shows the information about the gym membership and lunch habits of 100 physical therapists.

Given that a physical therapist brings their lunch to work, we can use the information in the table to calculate the probability that they do not use the gym membership. To do this, we'll use the formula:

P(not using gym membership | brings lunch) = P(not using gym membership and brings lunch) / P(brings lunch)

We can use the information in the table to find the values of P(not using gym membership and brings lunch) and P(brings lunch).

P(not using gym membership and brings lunch) = 40/100 = 2/5

P(brings lunch) = 60/100 = 3/5

So, the probability that a randomly chosen physical therapist does not use the gym membership given that they bring their lunch to work is:

P(not using gym membership | brings lunch) = P(not using gym membership and brings lunch) / P(brings lunch) = (2/5) / (3/5) = 2/3

Therefore, the probability that a randomly chosen physical therapist does not use the gym membership given that they bring their lunch to work is 2/3, in simplest form.

The circumference of a circle with a diameter of 26 feet is approximately 81.64 feet.

What is the circumference?

The circumference is the length of any great circle, the intersection of the sphere with any plane passing through its center. A meridian is any great circle passing through a point designated as a pole.

The formula for the circumference of a circle is 2 * π * r, where r is the radius of the circle.

To find the circumference, we first need to find the radius of the circle.

The diameter of the circle is 26 feet, so the radius can be calculated by dividing the diameter by 2:

r = 26 feet / 2 = 13 feet

Now that we know the radius, we can find the circumference:

C = 2 * π * r = 2 * 3.14 * 13 = 81.64 feet

Therefore, the circumference of a circle with a diameter of 26 feet is approximately 81.64 feet.

The required formula that describes the given variation is F = 1.6d².

The general formula to describe the variation that F is directly proportional to the square of d is F = kd²,

where k is a constant of proportionality.

To determine the value of k, we can use the given information that F = 40 when d = 5:

40 = k(5)²

40 = 25k

k = 40/25

k = 1.6

Substituting this value of k into the general formula, we get:

F = 1.6d²

The area of the Taj Mahal is 9092.16 square meters (97,890.56 square feet).

The quantity of square units required to completely cover a square is known as the area of a square. The territory that lies inside the confines of a flat item or a two-dimensional figure is generally referred to as the area. The measurement is made using square units, with square meters serving as the standard unit.

The Taj Mahal has an area of 9092.16 square meters (97,890.56 square feet). We utilise the formula for calculating the area of a square, which is length x width. The Taj Mahal's length and width are both 95.4 metres, therefore we just multiply these two values together. 9092.16 square meters = 95.4 × 95.4 square meters (97,890.56 square feet).

In other words, the collection of all feasible values for the parameters that satisfy the specified mathematical equation is the convenient storage of the bunch of equations.

Let 'x' be the number of hours and 'y' be the price of stocks. Then the equations are written as,

y = 13.52 + 0.05x           ...1

y = 14.27 - 0.14x             ...2

From equations 1 and 2, then we have

The probability of 3 students arriving at a randomly selected office hour is 0.27(27%). This can be calculated by using the Poisson distribution equation which is P(x)=e^(-λ)*(λ^x/x!).

In the above equation, λ is equal to the average number of arrivals which is 3.3. Plugging these values into the equation gives us  P(3)= e^(-3.3)*(3.3^3/3!) = 0.27, this means that the probability of 3 students arriving in randomly selected office hours is 0.27.The Poisson distribution is used to calculate the probability of a certain number of events occurring in a fixed interval of time or space.

The value of variables x and y are,

⇒ x = 80°

⇒ y = 130°

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Since, A parallelogram is forming here,

Then, Opposite angels are going to be equal.

Thus, We get;

⇒ y = (x + 50)°

Now, As you know that sum of all angles of a quadrilateral equals 360°

Hence, We get;

2 {(x + 50) + (x - 30)} = 360°

(x + 50) + (x - 30) = 180°

2x + 20 = 180

2x = 160

x = 80°

So, We get;

⇒ y = (x+50)

Answer:

-1.5

Step-by-step explanation:

The gradient of a line can be found using the formula:

gradient = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are the coordinates of two points on the line.

So for the line that passes through (3, 7) and (1, 10), the gradient can be found as:

gradient = (10 - 7) / (1 - 3)

gradient = 3 / -2

gradient = -1.5

So the gradient of the line that passes through (3, 7) and (1, 10) is -1.5.

A system of equations that could be used to find the length (in hours) of each type of workout

7a + 9b = 12

5a + 3b = 6

Solve this system of equations by multiplying both sides of one of the equation so that when the equations are added or subtracted there will only be one variable.

-I will multiply both sides of the 2nd equation by -3

-3*(5a + 3b) = 6*-3

-15a - 9b = -18

-Now I will get rid of the variable b by adding the two equations together.

      7a + 9b = 12

+   -15a - 9b = -18

     -8a = -6

a = -6/-8

a= 3/4 (45 minutes)

-Now plug 3/4 into one of the original equations as a to solve for b.

-I will use the 2nd original equation.

5a + 3b = 6
