The primary areas of study in statistics include data collection, organization, organization, analysis, interpretation, and presentation. It is customary to begin with a statistical population or a statistical model that will be examined when applying statistics to a scientific, industrial, or social problem. There are many different groups of people or things that can be referred to as populations, such as "each person living in a country" or "each atom making up a crystal." Every aspect of data is covered by statistics, including the planning of data collection in terms of survey and experiment design. Statisticians gather data using custom experiment designs and survey samples in the absence of census data.

On 1 June Sipho opened a savings account at the Postbank that paid 4.5% interest. He deposited R600. Ten days later on 10 June he deposited R1 000.F days later on 15 June he deposited R500. No other deposits or withdrawals w made. Fifteen days later, at the end of the month, the bank calculated the nterest. a. How much simple interest (calculated to the nearest cent) did he earn? . What was the balance of the account at the end of the first 30 days?
Sipho earned R33.15 in simple interest.
The balance of the account at the end of the first 30 days was R2 133.15.
How to calculate thisa. To calculate the simple interest earned by Sipho, we need to calculate the total amount deposited and the interest earned on that amount.
Total amount deposited = R600 + R1 000 + R500 = R2 100
Interest earned = R2 100 x 4.5% x 30/365 = R33.15 (rounded to the nearest cent)
Therefore, Sipho earned R33.15 in simple interest.
b. The balance of the account at the end of the first 30 days can be calculated by adding the total amount deposited and the interest earned to the initial deposit:
Balance = R600 + R1 000 + R500 + R33.15 = R2 133.15
Therefore, the balance of the account at the end of the first 30 days was R2 133.15.

how many such strings are if 2 of the ones are to be next to each other and the third is not next to the other two?
The number of strings where exactly two of the ones are next to each other, while the third one is not next to the other two, is (n-1) x (n-2).
In combinatorics, one of the fundamental concepts is counting the number of strings or sequences of symbols that satisfy certain conditions.
Let us first consider the case where the two ones that are next to each other are at the beginning of the string. In this case, we can place the third one in any of the remaining positions, which are n-2, where n is the total length of the string. Therefore, the number of such strings is (n-2).
Similarly, if the two ones are at the end of the string, we can place the third one in any of the n-2 remaining positions, and the number of such strings is again (n-2).
Now let us consider the case where the two ones are in the middle of the string. In this case, we can place the two adjacent ones in (n-2) ways, and the third one can be placed in any of the remaining n-3 positions, since it cannot be adjacent to the other two ones. Therefore, the number of such strings is (n-2) x (n-3).
To get the total number of strings that satisfy the given condition, we need to add up the number of strings in each of the three cases:
Total number of strings = (n-2) + (n-2) + (n-2) x (n-3)
Simplifying this expression, we get:
Total number of strings = (n-1) x (n-2)

When the time is 5 years, it would be written as f(5), and the t term in the function will be set to 5 for the calculation, which will yield the value of the investment at that time.
Danielle earns a 7.75% commission on everything she sells at the electronics store where she works. She also earns a base salary of $725 per week. What were her sales last week if her total earnings for the week were $1,058.25?
Danielle's sales last week were $
Danielle's sales last week were $. At her job at an electronics store, Danielle receives a $4,295.16 commission on every sale.
What is an electronics store?
Courses in calculus (single and multivariable), complex analysis, differential equations (both ordinary and partial), linear algebra, and probability are typically required for jobs in electronics engineering. Additionally, topics like Z-transforms and Fourier analysis are frequently covered in electrical engineering curricula.More mathematics is required for electronics and telecommunications technicians, such as complex numbers, trigonometry, basic geometry, fundamental statistics, and differential and integral calculus.Every subject wants their students to be able to examine mathematics using technology, such as spreadsheets.Let's start by first finding out how much commission Danielle earned last week. We know that her total earnings were $1,058.25 and her base salary was $725 per week. Therefore, her commission must have been:
$1,058.25 - $725 = $333.25
We also know that Danielle earns a 7.75% commission on everything she sells. Let's use "x" to represent her total sales last week. Then we can set up an equation to solve for x:
0.0775x = $333.25
Solving for x, we get:
x = $333.25 / 0.0775
x = $4,295.16
Therefore, Danielle's sales last week were $4,295.16.

how many pattern block triangles would create 2 hexagons
To make two hexagons out of pattern blocks, you would need a total of 12 triangles. Six triangles are needed for each hexagon.
To make two hexagons out of pattern blocks, you would need a total of 12 triangles. Each hexagon requires six triangles to make it, so two hexagons would need double that amount. Since the pattern blocks come in the shapes of triangles, you can easily construct the hexagons by placing the triangles together. Each triangle has two sides that fit together and two sides that overlap, so the six triangles will create a complete hexagon when they are all put together. Once you have two hexagons constructed, they will fit together to make a larger shape, depending on how you place them. With this method, you can easily make two hexagons out of pattern blocks.

Which ordered pair is a solution of the equation? y=4x-7
A only (2,1)
B only (4, 9)
C both ( 2,10) and (4,9)
D neither
Answer: To find the ordered pair that is a solution of the equation y = 4x - 7, we need to substitute the values of x and y into the equation and see if it is true.
If (x, y) is a solution, then y = 4x - 7 must be true for that particular x and y.
Option A: (2, 1)
Substituting x = 2 and y = 1 into the equation, we get:
1 = 4 * 2 - 7
1 = 8 - 7
1 = 1
Since the equation is true for x = 2 and y = 1, (2, 1) is not a solution of the equation.
Option B: (4, 9)
Substituting x = 4 and y = 9 into the equation, we get:
9 = 4 * 4 - 7
9 = 16 - 7
9 = 9
Since the equation is true for x = 4 and y = 9, (4, 9) is a solution of the equation.
Option C: Both (2, 10) and (4, 9)
Substituting x = 2 and y = 10 into the equation, we get:
10 = 4 * 2 - 7
10 = 8 - 7
10 = 3
Since the equation is not true for x = 2 and y = 10, (2, 10) is not a solution of the equation.
So, the only ordered pair that is a solution of the equation y = 4x - 7 is (4, 9). The answer is B) only (4, 9).

What are similar triangles?Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is indicated here by the symbol "."
The two triangles are similar thus the measure of its angle are also equal.
Using the similar triangle we have:
Angle D = Angle A = 82 degrees.
Angle F = 67 degrees
Using the sum of interior angles of triangle we have:
∠D + ∠F + ∠E = 180
82 + 67 + ∠E = 180
∠E = 31
From the figure we observe that,
∠E + ∠G = 180 (straight line)
31 + ∠G = 180
∠G = 149
Hence, the value of ∠E = 31 degrees and the value of ∠G = 149 degrees for the given triangle.

Multiply and simplify. Show work to earn full credit. (2 − 3)(7 2 − + 8
We can make advantage of the distributive property of multiplication over addition, which says that a(b + c) = ab + ac. As a result, -55 is the simplified expression.
What is distributive property, and what are some examples?When you multiply a value by a sum, the distributive property of multiplication over addition is put to use. For instance, you wish to multiply 5 by the product of 10 plus 3. Since the numbers are similar terms, we typically add the numbers first and then multiply by 5=> 5(10 + 3) = 65.
What is distributive property class 7?An algebraic principle known as the distributive property indicates that it is necessary to multiply each of the two integers by the factor being multiplied by the sum or difference of two terms.
Using this property, we can expand the expression as follows:
(2 − 3)(7 2 − + 8) = 2(7 2 − + 8) − 3(7 2 − + 8)
Now we can simplify each term separately:
2(7 2 − + 8) = 2(49 − 2 + 8) = 2(55) = 110
and
−3(7 2 − + 8) = −3(49 − 2 + 8) = −3(55) = −165
Therefore, putting the results together, we have:
(2 − 3)(7 2 − + 8) = 110 − 165 = -55

number of boys : number of girls = 11: 9
There are 124 more boys than girls.
Work out the total number of students at the school.
Answer:
Step-by-step explanation:
Let's call the number of boys "b" and the number of girls "g". From the ratio, we know that b/g = 11/9.
Also, we know that b = g + 124, so we can substitute the second equation into the first:
b/g = 11/9
b = g + 124
g + 124 / g = 11/9
Cross multiply:
9g + 1112 = 11g
Solve for g:
-2g = -1112
g = 556
So there are 556 girls and 556 + 124 = 680 boys at the school.
The total number of students at the school is 556 + 680 = 1236.
