Yes this an example of simple random sampling.

What is simple random sampling?

Every person in the population has an equal probability of getting chosen in a simple random sampling. The entire population should be included in your sampling frame.

You might utilize instruments like random number generators or other methods that just rely on chance to carry out this kind of sampling.

Main Body:

It is uncommonly attainable to collect knowledge from each member of a gaggle of people once conducting analysis on them. In its place, you choose a sample. The population that may really participate within the study is that the sample.

As in this case we select 100 random people out of 1000 , so it is an example of simple random sampling.

The length of the right triangle, y is 8.94 units.

A right angle triangle is a triangle that has one of its angles as 90 degrees.

The sides of a right angle triangle can be found using trigonometric ratios or Pythagoras's theorem.

c² = a² + b²

where

Therefore,

12² - 8² = y²

144 - 64 = y²

y = √80

y = 8.94427191

After finding the ratio for each person, Ben will get $72

A ratio  shows the relative sizes of two or more values. Ratios can be shown in different ways:

It was given that Alice, Ben and Charlie are to share $213.

Ratio of Alice's share to Ben = 4 : 3

Ratio of Ben's share to Charlie = 8 : 5

Combining these ratios, their shared item (Ben's share) must be the same in each ratio.

Taking Alice's share to Ben, 4 : 3 and multiplying both parts by 8 to get an equivalent ratio, we have:

Alice : Ben = 4(8) : 3(8) = 32 : 24

Likewise, taking Ben's share to Charlie, 8 : 5 and multiplying both parts by 3, we have:

Ben : Charlie = 8(3) : 5(3) = 24 : 15

Combining these ratios, we have:

Alice : Ben : Charlie = 32 : 24 : 15

Adding the ratios together, we have: 32 + 24 + 15 = 71

If the money to be shared is $213, Ben's share will be:

[tex]\frac{24}{71}[/tex] × [tex]$213[/tex] = 72

Therefore, Ben will get $72 from the total amount of $213

Step-by-step explanation:

Answer: 4,5,6,7,8

Step-by-step explanation:

Let the first integer be A; then the five consecutive integers are A, A+1, A+2, A+3, and A+4.

If the sum of the first three equals the sum of the last two, then A + (A+1) + (A+2) = (A+3) + (A+4)

Combining, 3A + 3 = 2A + 7 … A =4

The five Integers are thus 4, 5, 6, 7, and 8

Domain: {-1,0,1,4}

Range: {3,5,35}

Step-by-step explanation:

The domain is the set of x values while range is the set of y values

Here, the set of x values would be -1 , 0 , 1 and 4

And the y values would be 5, 3, 5, and 35

When writing the domain and range, you put the values into brackets "{}" and put them in order from least to greatest. Also if there are repeated values you do not repeat them, you only put them once.

This means that the domain would be {-1,0,1,4}

And the range would be {3,5,35}

Answer: x∈(-3,-1)

The third degree polynomial function with zeros of −3, −1, and 4, and a y-intercept of −13 is y = -13/12 (x³ - 13x + 12)

Polynomial function:

polynomial function refers a functions of single independent variables, in which variables can occur more than once, raised to an integer power.

Given,

Third-degree, with zeros of −3, −1, and 4, and a y-intercept of −13.

Here we need to construct  a polynomial function with the stated properties and reduce all fractions to lowest terms.

The standard form for the third degree polynomial function is written as,

y = K (x + zero1) (x + zero2) (x + zero3)

Here we know the values of zeros as -3, -1 and -4.

Apply it on the general form,

y = K (x -3) (x - 1) (x + 4) ----------------------(1)

And the value of y intercept is -13 then the value of x is 0.

So, it can be written as,

-13 = K(0 - 3) (0 - 1) (0 + 4)

-13 = K (-3)(-1)(4)

-13 = K (12)

K = -13/12

Now, we have to apply these value on the equation (1), then we get,

y = -13/12 (x -3) (x - 1) (x + 4)

When we expand these, then we get the polynomial function as,

y = -13/12 (x³ - 13x + 12)

When a fair die with faces numbered 1 to 6, the probability that the number landing face up is less than 3 is 1/3.

The probability measures how likely an event to occur. The probability of an event A is defined as:

P(A) = number of ways that event A can occur / all possible outcomes

In the given problem, let x be any number of die's face, then

number of ways x will show up = 1

all possible outcomes = 6

Hence,

P(x) = 1/6

Numbers that are less than 3 is 1 and 3. Therefore,

P (x<3) = P(1) + P(2)

P (x<3) = 1/6 + 1/6 = 2/6 = 1/3

Therefore, we can conclude that the probability that the number landing face up is less than 3 is 1/3

The perimeter "P" is equal to the length of the base of one triangle multiplied by the "n" number of triangles in the figure plus two times the length of another side. The equation for the perimeter is P = 5n + 14.

We are given triangles. The triangles are arranged in a certain pattern. The length of the base of each triangle is equal to 5 units. The length of the other two sides is 7 units each. We conclude that all the triangles are isosceles. We need to find the relationship between the number of triangles and the perimeter of the figure. Let the perimeter of the figure having "n" number of triangles be represented by the variable "P".

P(1) = 14 + 5(1)

P(2) = 14 + 5(2)

P(3) = 14 + 5(3)

We can see and continue the pattern. The relationship between the perimeter and the number of triangles is given below.

z >1 for the given inequality for x.

To solve the following inequality for x.

-26 + 13z + 2 > 2 132

Since there is no x in this I'm assuming we are looking for z

Step 1: Simplify both sides

15r - 26 > -13z + 2

Step 2: Add 13z to both sides

15r - 26 + 13z > -13z + 2 + 13z

28 - 26 > 2

Step 3: Add 26 on both sides

28 - 26 + 26 > 2 + 26

28z > 28

Step 4: Divide both sides by 28z / 28 > 28 / 28

z > 1

To find the zero put f(x) = 0.

(x-10)^2-49 = 0

Including both sides of an equation, add 49.

(x-10)^2 - 49 + 49 = 49

(x-10)^2  = 49

To remove the exponent upon that left side of the equation, take the appropriate root of both sides.

x - 10 = ±√49

x - 10 = ±7

Solve each case;

a:  x - 10 = + 7

x = 7 + 10

x = 17 (greatest number)

A function assigns the value of each element of one set to the other specific element of another set.

The zeros of a function are defined as the values of the variable of the function such that the function equals 0. Graphically, the zeros of a function are the points on the x-axis where the graph cuts the x-axis. In other words, we can say that the zeros of a function are the x-intercepts of its graph.

Now, According t the question:

Given that, f(x) = (x - 1)(x + 2)(x − 3)

Therefore, the zeroes of the functions are -2, 1, and 3. The end behavior of the function is that if x approaches ∞ then f(x) approaches ∞, while if x approaches -∞ then f(x) approaches -∞, as can be observed from the given graph.

Hence, the zeroes of the functions are -2, 1, and 3.

As per given data of living children under 18 years of age , percent of children whose age is under 18 years lived with their mother only is equal to 39.3%.

As given in the question,

Let us consider 100% be the total percent representing the living status of children under 18 years of age

Given:

Percent of children living with both the parents = 49.2%

Percent of children living with only father = 8%

Percent of children living with neither of the parents = 3.5%

Let us consider percent of children living with only mother = x%

Required equation is:

( x + 49.2 + 8 + 3.5 )% = 100%

⇒ x + 60.7% = 100%

⇒ x = 100 - 60.7

⇒ x = 39.3%
