A concrete drain is 10m long, with an outside diameter of 1m and an inside diameter of 0.8m. Determine the volume of the concrete required to make the drain, to the nearest tenth of a cubic metre

A Concrete Drain Is 10m Long, With An Outside Diameter Of 1m And An Inside Diameter Of 0.8m. Determine

Answers

Answer 1

Answer: To calculate the volume of the concrete required to make the drain, we need to find the volume of the cylinder formed by the outside diameter of the drain and subtract the volume of the cylinder formed by the inside diameter of the drain.

The formula for the volume of a cylinder is:

V = πr^2h

where V is the volume, r is the radius of the base of the cylinder, and h is the height of the cylinder.

The radius of the base of the outside cylinder is 0.5m (the diameter of 1m divided by 2) and the height is 10m. The radius of the base of the inside cylinder is 0.4m (the diameter of 0.8m divided by 2) and the height is also 10m.

So the volume of the outside cylinder is:

V = π * 0.5^2 * 10 = 15.7 m^3

and the volume of the inside cylinder is:

V = π * 0.4^2 * 10 = 12.6 m^3

To find the volume of the concrete required to make the drain, we subtract the volume of the inside cylinder from the volume of the outside cylinder:

15.7 m^3 - 12.6 m^3 = 3.1 m^3

So the volume of concrete required to make the drain is approximately 3.1 cubic metres. To the nearest tenth of a cubic metre, this is 3.1 m^3.

Mary had a chance to elect a number from 1 to 20 randomly, what i the probability that the number i diviible by 3

Answers

The probability that the randomly selected numbers are divisible by 3 is 3/10.

What is probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.

An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

So, the probability that the randomly selected number is divisible by 3:

Numbers under 20 divisible by 3 are: 3, 6, 9, 12, 15, 18

Total numbers: 20

Probability formula: P(E) = Favourable events/Total events

Now, substitute values and calculate as follows:

P(E) = 6/20

P(E) = 3/10

Therefore, the probability that the randomly selected numbers are divisible by 3 is 3/10.

the distribution of the sample​ mean, ​, will be normally distributed if the sample is obtained from a population that is normally​ distributed, regardless of the sample size.

Answers

The statement that ,"distribution of sample​ mean(μ) will be normally distributed if sample is obtained from population that is normally​ distributed, regardless of sample size(n)" is True .

What is Normal Distribution ?

A Normal Distribution is a distribution that describes a symmetrical plot of data around the mean value, where width of curve is defined by standard deviation.

the Central Limit Theorem states that , for a normally distributed random variable "X" , with mean "μ" and standard deviation "σ" , the sampling distribution of the sample means with size "n" can be approximated to a normal distribution with mean  and standard deviation  is s = σ/√n   .

So , sample size restriction is only for non normal underlying distribution,

Therefore , by Central Limit Theorem the given statement is True .

Univariate data just has one variable. Since there is only one variable that varies, univariate data analysis is the most straightforward type of analysis.

In bivariate two different variables in this kind of data. The analysis of this kind of data focuses on linkages and causes, and it seeks to understand the causal connection between the two variables.

Answer:

Bar chart; because job classification is categorical.

Step-by-step explanation:

Categorical data:  Data that can be divided into groups (categories).

Numerical data:  Data that is in the form of numbers (also called "quantitative data").

Therefore, "job classification" is categorical data since the classifications such as employee, manager, senior manager, etc. are categories rather than numbers.

Box plots are used to show distributions of numerical data values.

Bar charts are used to show a comparison of values across different categories of data.

Therefore, a bar chart should be used to represent the data as the data is categorical.

Find the sale price of each washing machine. Use pencil and paper. Explain why Kareem should buy the first washing machine rather than the second if the machines are the same except for the selling price.

Answers

Answer: Because the first washing machine is cheaper

Step-by-step explanation:

Find the first washing machine price by taking 550 times 0.7 = $385

The second machine is first down by 20%, so take 550 times 0.8 =$440

Then 10% off, so take 440 times 0.9 = $396

So the first washing machine is cheaper than the second one $11

Power is an important part of many social and political systems, and is essential for effective leadership. It is an essential tool for achieving desired outcomes and can be used for good or for ill. Ultimately, power is a form of influence, and its use depends on the individual wielding it.

When  (a, b) appears on a graph, it is said to be symmetric around the x-axis if (a ,b) also appears there at the same time. A graph that is symmetric around the x-axis is shown in the following illustration. A graph is said to be symmetric around the y-axis if and only if (a ,b) and (a, b) are both present on it.

We replace all the x's with -x and check to see if we get an equivalent formula to determine algebraically whether a graph is symmetric with regard to the y axis. Example: A) To make y = x2 symmetric with regard to the y axis, we substitute y = (-x)2 = x2 for y = x2.

Ordered pairs (x, y) and and exist in equations or functions that are symmetric to the origin (-x, y). The original equation is symmetric with respect to the origin if you swap -x for x and -y for y in the equation and simplify.

If we reflect a function's graph about the y-axis, we will get the same graph since some functions might be symmetrical about the y-axis. We may reflect various functions about the x- and y-axis and obtain the same graph. These two symmetry kinds are known as even and odd functions.

[tex]AC^2 = AB^2 + BC^2[/tex] is the formula for the Pythagorean theorem, where AB is the perpendicular, BC is the base, and AC is the hypotenuse. All triangles with 90° angles are governed by the Pythagorean equation.

The triangle's hypotenuse, or c, is the side that faces away from the 90-degree angle.

while the sides closest to the 90° angle are denoted by a and b.

Given that the hypotenuse is 5 = c and one of the sides has a measure of 2 = x in the issue statement, we can calculate for y as follows:
