Find the population variance ad standard deviation
6,12,20,24,28
The population variance ad standard deviation are 64 and 8 respectively.
The variance for a population is calculated by the below steps :
1) First find the mean (the average).
2) Subtracting the mean from each number in the data set and then squaring the result. The results are squared to make the negatives value positive
3) Averaging the squared differences.
Here, the data set of population is given as :
population difference difference²
6 -12 144
12 -6 36
20 2 4
24 6 36
28 10 100
₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋₋
∑ 90 ∑ 320
Now, the average population will be :
∑ 90/5 = 18
Now finding the variance σ² using the formula :
σ² = ∑(x- x')²/N
σ² = 320/5
σ² = 64
Now, the standard deviation σ will be :
standard deviation = √σ²
standard deviation = √64
standard deviation = 8
Therefore, the population variance ad standard deviation are 64 and 8 respectively.

Which of the following is an example of the Commutative Property? 2x + 3x = 5x 5xy = 5(xy) 5z - 3x = -3x + 5z 3(a + b) = 3a + 3b
From the given examples 5z - 3x = -3x + 5z and 5(xy) = 5(xy) are following the commutative property.
According to the given question.
We have some equations
2x + 3x = 5x
5xy = 5(xy)
5z - 3x = -3x + 5z
3(a + b) = 3a + 3b
Here, we have to find which equation is following the commutative property.
As we know that, the commutative property is a math rule that says that the order in which we multiply numbers does not change the product.
For, example 4 + 5 gives 9, and 5 + 4 also gives 9.
From the given example the equation
5z - 3x = -3x + 5z is following the commutaive property of addition.
And, 5(xy) = 5(xy) is following the commutative property of multiplication.
Hence, from the given examples 5z - 3x = -3x + 5z and 5(xy) = 5(xy) are following the commutative property.

The sum to infinity of the sequence is 96/13
Sum to infinity of a geometric sequenceGiven the nth term of a geometric sequence expressed as:
Tn = Σ12(-5/8)^n
The sum to infinity of the sequence is expressed as;
S∞ = a/1-r
where
a is the first term = 12
r is the common ratio = -5/8
Substitute
S∞ = 12/1-(-5/8)
S∞ = 12/1+5/8

C = F - A.
In which:
F is the best return.A is the actual return.For this problem, we have that:
When no tanks are produced, 1000 autos can be produced, hence F = 1000.When 3 tanks are produced, 650 autos can be produced, hence F = 650.Thus:
F = 1000 - 650 = 350.

If m is one sixth of n and p is five less than m, write a p as a function of n
p = (n - 30)/ 6 as a function of n.
Here we need to find the value of p in terms of n.
From the question, we have two equation
The first equation is:
m = 1/6n .......(1)
The second equation is:
p = m - 5.......(2)
From equations 1 and 2 we have to find the value of p in term of n.
So by putting the value of m in the second equation we have:
p = 1/6n - 5
= (n - 30)/6
Therefore we get the value of p as (n -30)/6 in terms of n.

b. M(2) = 14; If Hazel mows 2 yards, she will earn $14.
c. M(2) = 39; If Hazel mows a yard for 2 hours, she will earn $39.
d. M(2) = 14; If Hazel mows a yard for 2 hours, she will earn $14.
The correct option is M(2) = 39; If Hazel mows a yard for 2 hours, she will earn $39 . Option C
What is a function?A function can be defined as an expression that shows the relationship between an independent variable and a dependent variable.
Given the function;
M(t) = 7t + 25
Where;
M is the amount she earns per yardt is the time in hoursFor M(2), we substitute the value of t as 2 in the function
M(2) = 7(2) + 25
M(2) = 14 + 25
M(2) = $39
This explains that the she mows the yard for t = 2 hours, she would earn $39

5. The average monthly salary among a firm's twelve employees is 3500 € There are two part-time workers in the firm who both earn 2500 €/month. If the salaries of these two part-time workers are excluded from the average, what will the new average salary be? a) 3700 € b) 4300 € c) 4000 € d) other
Answer:
Choice a) 3700 €
Step-by-step explanation:
Total salary among 12 workers = Avg Salary x 12 = 3500 x 12 = 42,000 €
Total salary of 2 part-timers = part-time avg x 2 = 2500 x 2 = 5000
Total salary without part-timers salary= 42,000 - 5000 = 37,000 €
If we exclude the 2 part-timers, there are 10 full-timers who earn 37,000 €
So new Average Salary = 37000/10 = 3,700 €
