If a population consists of 5,400,000 people and a census is taken, how many
people are sampled?

If a chip is randomly drawn from the bag, the probability it will be a red or a blue one is P(red or blue) = 10/19.

Probability of an event A is the number of event A divided by all possible outcomes. Mathematically,

P(A) = n(A)/n(S)

where:

n(A) = number of event A

n(S) = number of all possible outcomes or sample space.

Suppose A and B are independent outcomes, then:

P(A or B) = P(A) + P(B)

In the given problem:

Number of chips:

Blue = 3

Red = 7

Yellow = 4

Green = 5

Total chips = 3 + 7 + 4 + 5 = 19

If a chip is randomly drawn, the probability it will be a red one is:

P(red) = 7/19

Similarly,

P(blue) = 3/19

Using the probability formula for independent outcomes:

P(red or blue) = P(red) + P(blue)

                      = 7/19 + 3/19 = 10/19

The number of players in the team will be 18.

What is an expression?

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

Given that;

Total cost to go to a tournament = $1885.50

Rent for bus = $949.50

Budget for meal for each player = $52

Now,

Let the number of players = x

So, We can formulate;

⇒ $949.50 + $52x = $1880.50

Solve for x, as;

⇒ $949.50 + $52x = $1880.50

Subtract 949.50 both side, we get;

⇒ $949.50 + $52x - $949.50 = $1880.50 - $949.50

⇒ $52x = $931

⇒ x = $17.90

After round we get;

⇒ x = $18

Thus, The number of players in the team will be 18.

No, the triangle with vertices (-1, -1), (2, 3), (-4, 3) is not equilateral.

An equilateral triangle is a triangle that has all three sides of equal length, also known as a "regular" triangle.

Now, as per the given question.

The vertices are given as (-1, -1), (2, 3), (-4, 3).

Find the distance between the two corresponding vertices.

First, find distances between (-1, -1), (2, 3) lets say 'c'.

c² = (-1-3)² + (-1-2)²

c² = 4² + 3²

c² = 16 + 9

c² = 25

c = 5

Now, find the distance between (2, 3), (-4, 3), let say it 'd'.

d² = (-4-2)² + (3-3)²

d² = 36

d = 6

Now, find the distance between (-1, -1), (-4, 3) say it 'p'

p² = (-1-(-4 ))² +(-1-3)²

p² = 3² +4²

p² = 25

p = 5

Only function 2 represent a linear function.

Herein we find four cases of functions, of which we are asked to determine if each function is linear or not. A function is linear if and only if the change between every pair of two consecutives values of x and y is the same. Now we proceed to check each case:

Function 1

Δx = - 1 - (- 3) = 2; Δy = 6 - 2 = 4

Δx = 1 - (- 1) = 2; Δy = 18 - 6 = 12

Δx = 3 - 1 = 2; Δy = 54 - 18 = 36

The function is not linear.

Function 2

Δx = 5 - 1 = 4; Δy = - 1 - 1 = - 2

Δx = 9 - 5 = 4; Δy = - 3 - (- 1) = - 2

Δx = 13 - 9 = 4; Δy = - 5 - (- 3) = - 2

The function is linear.

Function 3

Δx = 5 - 4 = 1; Δy = - 10 - (- 5) = - 5

Δx = 7 - 6 = 1; Δy = - 15 - (- 13) = - 2

The function is not linear.

Function 4

Δx = 1 - (- 2) = 3; Δy = 5 - 4 = 1

The amount of material needed to make the box is 41.5 ft².

The surface area of a figure is the number of unit squares it takes to cover the entire surface without gaps or overlaps. If a three-dimensional figure has flat sides, the sides are called faces. The surface area is the total of the areas of the faces.

Given that, a rectangular storage box is to be made with length is 3.5 feet, the width is 2 feet, and the height is 2.5 feet.

For finding the same, we will find the surface area of the box,

Surface area of the box = 2(length·width + width·height + height·length)

Therefore,

SA = 2(3.5x2+2x2.5+3.5x2.5)

SA = 2 x 20.75

SA = 41.5

Hence, the amount of material needed to make the box is 41.5 ft².

Notice the pattern:

10² = 100, so 10² - 9 = 91 with a digital sum of 9 + 1 = 10

10³ = 1000, so 10³ - 9 = 991 with a digital sum of 2•9 + 1 = 19

10⁴ = 10000, so 10⁴ - 9 = 9991 with a digital sum of 3•9 + 1 = 28

Then for an arbitrary power of 10, we have

[tex]10^n = 1\underbrace{00\ldots000}_{n\,\rm 0s} \implies 10^n - 1 = \underbrace{999\ldots99}_{n-1\,\rm9s}1 \\\\ \implies \text{digital sum} = 9(n-1)+1 = 9n - 8[/tex]

When [tex]n=51[/tex], the digital sum is 9•51 - 8 = 451.

Total 330 four-digit numbers can be formed if the number is odd and greater than 6000.

Let's tackle the problem in three steps.

First, take into account the numbers with "6" as the first digit on the left.

Then take the first eight digits of the numbers as the leftmost digit.

Last but not least, we'll use the numbers that begin with "7" as the leftmost digit.

1. As the leftmost digit, think of the numbers that begin with "6."

Any one of the final four odd digits—1, 3, 5, or 7—is acceptable (and recommended).

You are given four options.

You can use any of the remaining 8-1-1 = 6 digits for the second and third digit.

In all, it gives you 4×6×5  = 120 choices/numbers.

2.  Consider  the leftmost digit as the number starting with "6."

You have 120 more options/numbers using the same logic and analysis.

Everything is going well thus far, and you only need 120 + 120 = 240 numbers.

3.  Consider the numbers starting with "7" as leftmost digit.

Any of the final three odd digits—1, 3, and 5—may (and ought to) be used.

You have three options.

Any of the remaining 8-1-1 = 6 digits can be used for the second and third digit.

In all, it gives you 3×6×5  = 90 choices/numbers.

4. You have 120 + 120 + 90 = 330 numbers/options when everything is added up.

Hence we get 330 choices to create four digit numbers.

There are two cases in Unitary Method

Let's start with finding the price of one ice cream. Divide the entire cost of ice cream by the total number of ice creams to get at that. A single ice cream will cost you 125 divided by the amount of ice creams, or 25 cents. Consequently, 1 ice cream costs $25.

Step 2: To calculate the price of three ice creams, multiply the price of one ice cream by the quantity. Cost of 1 ice cream x number of ice creams = 25 x 3 = $75 is the price of 3 ice creams. The final cost is $75, which is the price of three ice creams.

Given:

For 1 1/2 or 3/2 hours tony charges = $37.50

For 1 hour tony charges = 37.50 * 2/3

                                        = 12.5 * 2

The value of x is 12.

Given on a line lie three points e, f and g.

therefore, ef = x ₋ 4

fg = 2x ₋ 9 and

eg = 13

we can say that ef and fg must add upto eg.

⇒ ef ₊ fg = eg

⇒ x ₋ 4 ₊ 2x ₋ 19 = 13

⇒ 3x ₋ 23 = 13

⇒ 3x = 13 ₊ 23

3x = 36

x = 36/3

x = 12

hence we get the value of x as 12.

now substitute x value to get ef and fg values.

ef = x ₋ 4  = 12 ₋ 4 = 8

fg = 2x ₋ 19 = 2(12) ₋ 19 = 24 ₋ 19 = 5
