What is arithmetic progression ?When there are identical differences between every two next words, the series is known as an arithmetic progression (AP). There is a chance to find a formula for the nth term of the AP using this kind of development. The series 2, 6, 10, 14, etc., for instance, is an example of an arithmetic progression (AP) because it follows a pattern in which each number is acquired by adding 4 to the preceding word.

In item b, increasing the population standard deviation [tex]\sigma[/tex] means that the denominator of the formula will be increasing, hence the test statistic will be decreased.
In item c, increasing the sample size n means that the denominator will be decreased, as the denominator is a fraction which is inverse proportional to the sample size, hence the test statistic z will be increased.

If the quotient of a number and 8 is added to 1/4 the result is 7/8. Find the number.
Answer:
5
Step-by-step explanation:
Let n be the unknown number.
The quotient is the result obtained by dividing one number by another.
Therefore, the quotient of a number and 8 is ⁿ/₈.
If the quotient of a number and 8 is added to 1/4 the result is 7/8:
[tex]\implies \dfrac{n}{8}+\dfrac{1}{4}=\dfrac{7}{8}[/tex]
To solve, make the denominators of all the fractions the same:
[tex]\implies \dfrac{n}{8}+\dfrac{1 \cdot 2}{4 \cdot 2}=\dfrac{7}{8}[/tex]
[tex]\implies \dfrac{n}{8}+\dfrac{2}{8}=\dfrac{7}{8}[/tex]
[tex]\textsf{Apply the fraction rule} \quad \dfrac{a}{c}+\dfrac{b}{c}=\dfrac{a+b}{c}:[/tex]
[tex]\implies \dfrac{n+2}{8}=\dfrac{7}{8}[/tex]
Multiply both sides by 8:
[tex]\implies \dfrac{8(n+2)}{8}=\dfrac{7 \cdot 8}{8}[/tex]
[tex]\implies n+2=7[/tex]
Subtract 2 from both sides:
[tex]\implies n+2-2=7-2[/tex]

By using the Vertical Angles Theorem, Corresponding Angles Theorem, and Alternate Exterior Angles Theorem we can prove that line m is parallel to line n.
In the given figure,
Let the given angles formed by transversal r, adjacent to line m be angle 1, and to line n be angle 2.
Now, the vertically opposite angle to angle 1 will be equal to it as they both are congruent.
The vertically opposite angle equal to angle 1 would be corresponding to angle 2 and corresponding angles formed by a transversal are equal and congruent.
Moreover, angle 1 and angle 2 are alternate exterior angles and by Alternate Exterior Angles Theorem, they are congruent.

In a recent year, 26% of all college students were enrolled part-time. If 4.4 million college students were enrolled part-time that year, what was the total number of college students? Round your answer to the nearest million.
Answer: 17 million
Step-by-step explanation:
We will set up a proportion to solve. We also will divide 26% by 100 to get a decimal, 0.26. We know that 26% of college students was 4.4 million, but we want to find 100%.
[tex]\displaystyle \frac{0.26}{4.4\text{ million}} =\frac{1}{x\text{ million}}[/tex]
Now, we will cross-multiply.
0.26 * x = 1 * 4.4
0.26x = 4.4
Lastly, we will divide both sides of the equation by 0.26. Then, we will round to the nearest million.
x = 16.923
x ≈ 17 million
what is this equation rewritten in the form that reveals the minimum of the function
We are given the quadratic function c(p) = p^2 - 28p + 250 and we need to rewrite this in such a way that the minimum value is easy to find.
Remember that the vertex
[tex]f(x)=a(x-h)^2+k[/tex]where (h, k) is the vertex or the minimum point.
We use completing the squares method to do this. We divide the second term, -28p, by 2p, then square it.
[tex](\frac{-28p}{2p})^2=(-14)^2=196[/tex]We add 196 to p^2 - 28p to make it equal to (p - 14)^2, but since it will change the value of the equation, we need to subtract the same value from 250 so that the net effect is zero.
[tex]\begin{gathered} c(p)=p^2-28p+250 \\ c(p)=(p^2-28p+196)+250-196 \\ c(p)=(p-14)^2+54 \end{gathered}[/tex]The equation is c(p) = (p - 14)^2 + 54.

The expression equivalent to [-40 + (-20) + (-60)] is [−20 + (−40) + (−60)]
As per the question statement, we are provided with a linear expression of [-40 + (-20) + (-60)], and four options.
We are supposed to determine the one expression from the given options, that is equivalent to the question mentioned expression of [-40 + (-20) + (-60)].
To solve this question, we will first calculate the value of the question mentioned equation, and then, calculate and compare the values of individual expressions provided in the options, to obtain our desired answer.
Therefore, [-40 + (-20) + (-60)] = [-40 - 20 -60]
or, [-40 + (-20) + (-60)] = -( 40 + 20 + 60)
or, [-40 + (-20) + (-60)] = -120.
Now, coming to the first option, expression [−40 − (20 − 60)] equates to
[-40 - (-40)] = (-40 + 40) = (40 - 40) = 0,
And [0 ≠ (-120),
Hence, [−40 − (20 − 60)] is not the equivalent expression to
[-40 + (-20) + (-60)].
Now, coming to the second option, expression [-(40 − 20) + (-60)] equates to [-(20) + (-60)] = (-20 - 60) = -(20 + 60) = (-80),
But again, [(-80) ≠ (-120)],
Hence, [-(40 − 20) + (-60)] is not the equivalent expression to
[-40 + (-20) + (-60)].
Coming to the third option, expression [40 + 20 + 60] equates to (120)
But again, [120 ≠ (-120)],
Hence, [40 + 20 + 60] is not the equivalent expression to
[-40 + (-20) + (-60)].
Finally, Coming to the last option, expression [−20 + (−40) + (−60)] equates to (-20 - 40 - 60) = -(20 + 40 + 60) = (-120).
And [(-120) = (-120)],
Hence, [−20 + (−40) + (−60)] is the required equivalent expression to
[-40 + (-20) + (-60)].

A plane traveled 3465 miles with the wind in 5.5 hours and 3245 miles against the wind in the same amount of time. Find the speed of the plane in still air and the speed of the wind.
The speed of the plane in still air is
The speed of the wind is
The most appropriate choice for speed will be given by-
Speed of plane in still air = 610 miles/hour
Speed of wind = 20 miles/hour
What is speed?
Distance travelled by a body in unit time is called speed.
Let the speed of plane in still air be x miles/hour
Speed of wind be y miles/hour
A plane traveled 3465 miles with the wind in 5.5 hours
So,
x + y = [tex]\frac{3465}{5.5}[/tex]
x + y = 630.......(1)
The plane travelled 3245 miles against the wind in the same amount of time
so,
x - y = [tex]\frac{3245}{5.5}[/tex]
x - y = 590.......(2)
Adding (1) and (2),
2x = 1220
x = [tex]\frac{1220}{2}[/tex]
x = 610 miles/hour
Putting the value of x in (1),
610 + y = 630
y = 630 - 610
y = 20 miles/hour
Speed of plane in still air = 610 miles/hour
Speed of wind = 20 miles/hour

The lengths of the rectangle for which the area will be less than 125 cm² is 5 < m < 25
In this question, we have been given the width of a rectangle is fixed at 5 cm.
We need to determine (in terms of an inequality) those lengths for which the area will be less than 125 cm²
Let 'm' be the length of the rectangle.
The area of the rectangle is:
A = length × width
The area of the rectangle should be less than 125 cm²
5 × m < 125
Divide both the sides of the inequality by 5
m < 25
This means, the length of rectangle should be less than 25 cm
But length is always greater than the width of the rectangle.
So, we get an inequality 5 < m < 25
Therefore, the lengths of the rectangle for which the area will be less than 125 cm² is 5 < m < 25

[tex]\begin{gathered} \sqrt{50x^3}=\sqrt{25\times2\times x^2\times x} \\ =\sqrt{25\times2\times x^2\times x}=\sqrt{5^2\times2\times x^2\times x}=\sqrt{5^2}\times\sqrt{x^2}\times\sqrt{2x} \end{gathered}[/tex]Thus

Answer:
Side = 10 units
Step-by-step explanation:
Original square area = s x s =s^2
now change the sides and this equals 6s^2
3s * ( s+10) = 6 s^2
3s^2 -30s = 0
s ( 3s-30) = 0 so s = 0 or 10
