In 4 months, the total cost of Yoga Studio A would equal that of Yoga Studio B

What is total ?

Total refers to an entire or complete amount, and the verb "to total" means to combine two numbers or to destroy anything. In mathematics, you add integers to get the total; the outcome is the total. The result of adding 8 and 8 is 16.

The cost of Yoga Studio A at any given month can be represented as:

= Membership fee + (Monthly fee x Number of months)

Assuming number of months is x, the formula would be:

= 24 + (21.50 × x)

= 24 + 21.50x

Yoga Studio B would be:

= 41 + (17.25 × x)

= 41 + 17.25x

In order to find the month that these costs would be equal, equate both formulas:

24 + 21.50x = 41 + 17.25x

21.50x - 17.25x = 41 - 24

4.25x = 17

x = 17 / 4.25

x = 4 months

Consecutive integers are a set of positive whole numbers which follows one another respectively. Thus the required proof to the question is as explained below:

The theorem states that:[tex]/hypotenuse/^{2}[/tex] = [tex]/adjacent/^{2}[/tex] + [tex]/opposite/^{2}[/tex]Thus a set of consecutive numbers which represent each side of a right angled triangle must obey the Pythagorean theorem.

Consecutive integers are a set of positive whole numbers which follows one another respectively. Examples are; 20, 21 and 22, 2, 3 and 4 etc.Therefore, the three consecutive integers that are also Pythagorean tribble are 3, 4 and 5.

So that let the adjacent side be 3, and the opposite side 4, then;[tex]/hypotenuse/^{2}[/tex] = [tex]/adjacent/^{2}[/tex] + [tex]/opposite/^{2}[/tex]                       = [tex]3^{2}[/tex] + [tex]4^{2}[/tex] = 9 + 16                       = 25

The equation of the line through (1, 2) so that the segment of the line intercepted between the axes is y+2x=4.

Let's use the slope-intercept form to find the equation of the line,

Hence the equation of the line would be of the form y=mx+c,

now the point at which the line intersects X-axis is (a,0), and the point at which it intersects Y-axis is (0,b).

⇒ m×a+c = 0

⇒a= − c/m

​and b=c+0 ⇒ b=c

Now, (1,2) is the midpoint of (a,0) and (0,b)

ie. 2=(0+b)/2​ ⇒ c/2 ​=2

                  ⇒c = 4

and  1=(a+0)/2​ ⇒ 1= −c/2m​

Steady state vector represent the long term market share of both groceries i.e WB and ZA. The long term market share of ZA is 0.727...

The steady-state behavior of a Markov chain is the long-term probability that the system is in each state. In other words, no matter how many transitions are applied to the system, it does not affect the state vector.

We have, WB and ZA are two competing grocery stores.

Probability that a customer who shops this week at WB will shop again here next week , p₁= 64% = 0.64

Probability(not shop again from WB) = 1-p₁

= 1 - 0.64 = 0.36

Probability that a customer who shops this week at ZA will shop again here next week , p₂ = 76% = 0.76

P(not shop again from ZA) = 1- p₂= 1 -0.76

= 0.24

Let market share of WB and ZA be "x" and "y" respectively, So, steady state vectors , s = [x y]

and x + y = 1 ---(*)

The Transition matrix, P=[1- p₁ p₁ ; 1-p₂ p₂]

P = [ 0.36 0.64 ; 0.24 0. 76 ]

we have to determine the value of x and y . So, we solve the following matrix equation, s[ I - P] = 0

matrix where I is identity matrix of 2×2

=> s([ 1 0 ; 0 1 ] - [0.36 0.64 ; 0.24 0. 76 ] ) = [0 0 ; 0 0 ]

=> s[1- 0.36 0- 64 ; 0 - 0.24 1 -0.76]

=[0 0 ; 0 0]

=> s[ 0.64 - 0.64 ; - 0.24 0.24] = [0 0;0 0]

=> [ x y] [0.64 -0.64 ; -0.24 0.24] = [0 0; 0 0]

Matrix multiplication,

=> [ 0.64x - 0.24y ; - 0.64x + 0.24y ]

= [ 0 0 ; 0 0]

equating the LHS and RHS

0.64x - 0.24y = 0 --(1)

- 0.64x + 0.24y = 0 --(2)

If we multiply equation (1) by -1 then we get equation(2). So, both equations are identical and we can collpase them in one equation for further calculation. Now, we have to equations

0.64x - 0.24y = 0 --(3)

x + y = 1

we can solve these equations either matrix method or substitution. We use here substitute

x = 1- y in equation (3) we get

0.64x - 0.24y = 0=> 0.64(1 - y) - 0.24 y = 0

=> 0.64 - 0.64y - 0.24 y = 0

=> 0.64 = 0.88y

=> y = 0.64/0.88 = 8/11 = 0.727

from equation (*) , x = 1 - 8/11 = 3/11 = 0.272
