A stationery shop orders a batch of pens from a factory. The factory could make the batch of pens in 20 days using 12 machines. Due to a fault, only 9 machines were used for the first 8 days. All 12 machines were used from day 9 onwards. Work out the total number of days taken to make the batch of pens.
Answers
The number of days taken to complete the production of a batch of pens are 22, as calculated by basic algebra.
What is basic algebra?Numbers, variables, constants, expressions, equations, linear equations, and quadratic equations are all part of the basics of algebra. Additionally, the algebraic expressions contain the basic arithmetic operations of addition, subtraction, multiplication, and division.
Now, According to the question, the factories used all 12 machines in the last days, Also, for the first 8 days, only 9 machines were in use.
Thus, If the factories used all 12 machines, the batch of pens took 20 days to be manufactured.
Hence, the equation formed from the given information by basic algebra is: 20 + 12 - 9(8) / 12
28 - (72/12)
=28 - 6 = 22
Hence, The number of days taken to complete the production of a batch of pens are 22, as calculated by basic algebra.

Step-by-step explanation:
Find out how many times an element(data value) appears. That will be the frequency(column 2). The cumulative frequency is the total of all frequencies prior to that element plus the current element frequency
Cumulative frequency for first element is same as its frequency
Cumulative frequency for element 16 is 3 + 6 = 9
Cumulative frequency for element 17 = 3 + 6 + 1 = 9 + 1=10. Basically it is the sum of the previous element cumulative frequency + the current frequency
The table shows the current heights and average growth rates of two different species of trees. State and solve an equation to find how long it will take for the two trees to be the same height.
Help with showing equation an answer please!!
Answers
The two different species of plants will take 5 years to reach the same height.
Given, from the table :
Tree specie A has a:
current height = 38 inches
and its annual growth = 4 inches
Therefore, total height is:
38 + 4x .. eq (1)
Tree specie B has a:
current height = 45.5 inches
and its annual growth = 2.5 inches
Therefore, total height is:
45.5 + 2.5x .. eq (2)
Equate equation 1 and equation 2.
38 + 4x = 45.5 + 2.5x
Subtract the constants.
4x = 45.5 - 38 + 2.5x
4x = 7.5 + 2.5x
now subtract the variables.
4x - 2.5x = 7.5
1.5x = 7.5
x = 7.5/1.5
x = 5
Hence the trees will take 5 years to reach the same height.

Answers
(3a) The 95% confidence interval of σ[tex]_{1}^{2}[/tex]/σ[tex]_{2}^{2}[/tex] is: [0.1932 , 1.2032].
What is variance?Variance is the anticipated squared deviation of a random variable from its population mean or sample mean in probability theory and statistics.
F test for variances, using F distribution ([tex]df_{num}[/tex]=19,[tex]df_{denom}[/tex]=20) (two-tailed) (validation).
Hypotheses
[tex]H_{0}:sigma_{1} = sigma_{2}\\\\H_{1}:sigma_{1}\neq sigma_{2}[/tex]
1. H0 hypothesis
Since p-value > α, H0 is accepted.
The sample standard deviation (S) of LaJolla.res' population is considered to be equal to the sample standard deviation (S) of Pt.Loma.ke's population.
In other words, the difference between the sample standard deviation (S) of the LaJolla.res and Pt.Loma.ke populations is not big enough to be statistically significant.
2. P-value
The p-value equals 0.1152, ( p(x≤F) = 0.05759 ). It means that the chance of type I error, rejecting a correct [tex]H_{0}[/tex], is too high: 0.1152 (11.52%).
The larger the p-value the more it supports [tex]H_{0}[/tex].
3. The statistics
The test statistic F equals 0.4796, which is in the 95% region of acceptance: [0.3986 : 2.4821].

What is primitive root?In modular arithmetic, a number g is called a primitive root modulo n if every number coprime to n is congruent to a power of modulo . Mathematically, g is a primitive root modulo n if and only if for any integer a such that gcd(a, n)=1 , there exists an integer k such that:

Now,
Existence of Primitive root modulo n exists if and only if:

if n be a positive integer. A primitive root mod n is an integer g such that every integer relatively prime to n is congruent to a power of g mod n.
For example,
As ϕ(11)=10, the order of 2(mod11) must divide 10.
So we check 22≡4(mod11) and 25≡10(mod11).
Since neither of these are 1, and
we know 2ϕ(11)=210≡1(mod11) by Euler's Theorem,
ord112=ϕ(11), making 2 a primitive root modulo 11.

If angle 6 measures 9x+13 and angle 2 measures 11x-3 what is the measurement of angle 2
Answers
The measure of an angle 2 is 85°.
Given that, ∠6=9x+13 and ∠2=11x-3.
What are corresponding angles?Corresponding angles are the angles which are formed in matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line.
As we know, corresponding angles are congruent.
So, ∠6= ∠2
⇒ 9x+13=11x-3
⇒ 13+3=11x-9x
⇒ 16=2x
⇒ x=8
Now, ∠2=11x-3
