To subtract in mathematics is to take something away from a group or a number of objects. The group's total number of items decreases or becomes lower when we subtract from it. The components of a subtraction issue are the minuend, subtrahend, and difference. An arithmetic operation called subtraction simulates the process of deleting items from a collection. The action of subtracting a matrix, vector, or other quantity from another according to predetermined rules in order to find the difference.

The variance of the number of male students is 7.42 if the university has 10,000 students of which 45% are male and 55% are female.

It is described as a collection of data with the same entity that is linked to a problem. The sample is a subset of the population, yet it is still a part of it.

P(male) = 45% = 0.45

P(female) = 55% = 0.55

Variance = SD²

Variance  = nP(male)xP(male)

Variance  = 30x0.45x0.55

Variance = 7.42

Thus, the variance of the number of male students is 7.42 if the university has 10,000 students of which 45% are male and 55% are female.

CORRECT OPTION: 2 should be distributed as 2y + 12; y = 6

Answer:

x = 5, y = 13

Step-by-step explanation:

Solve for x:
42 = 8x + 2

40 = 8x

x = 5

This is solved using the alternate interior angles theorem, which states that alternate interior angles (in this case, the 42-degrees and 8x + 2 degree angles) are the same.

Solve for y:

180 = 42 + 6(2y - 3)

180 = 42 + 12y - 18

180 = 24 + 12y

156 = 12y

y = 13

This is solved using the same-side interior angles theorem, which states that same-side interior angles (in this case, the 42-degrees and 6(2y-3)-degree angles) add up to 180 degrees.

Firstly, we want to start by drawing the triangles

We have this as follow;

For triangle HOT, we have;

We want to get the values of x and y firstly

Since both triangles are congruent, the order of the sides match

Hence, we have angle O and H equal

Thus, we have that;

Now, to find Y, we need the measure of angle N

Angle N is same as W which we already have as 5y+ 26

Substitute N for Y

Since all the angles of a triangle sum up to 180, we have it that;

Now, we want the measure of each of the angles;

1. W = N = 5y+ 26 = 5(13) + 26 = 91

2. H = O = 5x-1 = 5(9) - 1 = 44

3. Y = T = 4x + 9 = 4(9) + 9 = 45

Answer:

E' will be at (2, -6)

Step-by-step explanation:

Here we are given point E at (2, 6).

A reflection over the x-axis will keep the x coordinate the same while changing the y value to become the additive inverse (the number in which adding to the current value will get you zero). In this case, it is -6.

E (2,6) --> E' (2, -6)

Another way of thinking of it is reflecting on the x-axis while change the value from (x, y) to (x, -y).

The best estimate for the pigeon population is 540.

Finding an estimate or approximation—a value that may be used for a purpose despite the possibility of incomplete, ambiguous, or unstable input data—is the process of estimation. Despite this, the value is still useful because it was created using the most up-to-date data.

Counting a small sample of something and extrapolating that number to a wider population is how estimation is frequently done. Calculating how many sweets of a certain size are contained in a glass jar is an example of estimation.

The correct equation to be written for 500 will be 5*100 = 500. This same can also be written as 50*10 = 500 in the equational form to represent 500.

A mathematical equation can be stated as a formula that uses the equals sign in order to represent the equality of two expressions. In other words, it's a statement that shows that the values of two mathematical expressions are equal.

The equality between the equations here is shown by the equals (=) sign

As an example, 3x + 5 = 14 can be stated as an equation, in which 3x + 5 and 14 are two expressions that are connected by an ‘equal’ sign, thus providing an equation form.

The area of Desert A is 500,000 square miles and the area of Desert B is 100,000 square miles.

What is area?

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

Area of a square is side × side.

Let the area of Desert A = x square miles

and the area of Desert B = y square miles

Given that, the area of Desert A is five times the area of Desert B,

i.e. x = 5y                         ...(1)

and the sum of their areas is 600,000 square miles,

i.e.  x + y = 600,000  square miles                  ...(2)

Putting equation (1) in (2), we get

         5y + y = 600,000

or        6y = 600,000  or      y =  100,000  square miles

Using equation (1),

  x = 5 × 100,000 = 500,000  square miles

Hence, the area of Desert A is 500,000 square miles and the area of Desert B is 100,000 square miles.

The mean number of unoccupied seats per flight during the past year will lie between 11.15 and 12.05.

What is mean in mathematics?

There are many mean types in maths, particularly in statistics. Each mean serves to condense a specific set of data, frequently so that the general magnitude and sign of the data set can be better understood.

The arithmetic mean, also referred to as "arithmetic average," is a calculation that divides the total number of values in a data collection by their sum to get the central tendency of that set of numbers.

a) Calculations:

Degrees of freedom = n - 1 = 225 - 1 = 224

For 224 degrees of freedom and 90% confidence interval,

Critical t value = 1.652

Hence,

90% confidence interval will be:

[tex]11.6 \pm 1.652*4.1/\sqrt{225}[/tex]

[tex]11.6 \pm 0.45[/tex]

(11.15, 12.05)

b) Interpretation:

We are 90% confident that the population mean number of unoccupied seats will lie between 11.15 and 12.05

c) Caution with interpretation:

In this scenario, individual confidence interval should be calculated rather than mean number of unoccupied seats since we can't generalize this interpretation for individual flights.

d) To narrow a confidence interval, we can either increase the sample size or can decrease the confidence level.
