Answer:

y = 5x

Step-by-step explanation:

Assuming you require the proportional equation

Given that y is directly proportional to x then the equation relating them is

y = kx ← k is the constant of proportion

To find k use the condition when y = 30, x = 6 , then

30 = 6k ( divide both sides by 6 )

5 = k

y = 5x ← equation of proportion

IgorC [24]

Answer:

a)   P₁  = 250 and    P₂ = 300

b) The explicit formula   Pₙ = 150+ 50 n

c)  P_{60}  = 3150

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that Pₙ = pₙ₋₁ +50 and P₀ = 200

Put n =1

         P₁ = P₀+50 = 200+50 = 250

Put n =2

         P₂ = P₁+50 = 250+50 = 300

Put n=3

       P₃ = P₂+50 = 300+50 = 350

and so on

The sequence     200,250,300,350,..

<u><em>Step(ii):- </em></u>

The sequence     200,250,300,350,.. is an arithmetic sequence

The explicit formula

       Pₙ = a+(n-1)d

       Pₙ = 200+(n-1)50

       Pₙ = 200+ 50 n -50

        Pₙ = 150+ 50 n

The explicit formula   Pₙ = 150+ 50 n

c)

The n^{th} term of the sequence

       Pₙ = 150+ 50 n

put n=60

      P_{60} = 150 + 50 (60) = 3150

MATH QUESTION HELP PLZ
Phantasy [73]

Answer:

Step-by-step explanation:

You have to first enter these values into a table.  You find that table on your calculator at "stat" then "edit".  In L1, enter all the x values, hitting "enter" after each entry.  Then arrow over to L2 and enter all the y values.  When you are done, hit "stat" again, then "calc" and choose 4 LinReg, then hit enter.  If you do not see the r and r-squared values, then you need to turn on your diagnostics.  To do this, hit 2nd, then 0 to pull up your catalog.  Hit the x^{-1} button and that brings up all the D's in your catalog.  Arrow down til you see "DiagnosticsOn" and hit enter.  Then hit enter again.  Go back to "stat", "calc", "4 LinReg" and hit either enter or calculate (it depends upon which calculator you have.  The TI 83 just needs the "enter" button, while the TI84 family requires that you scroll down to the word "calculate" and hit "enter").  Then when the linear regression equation comes up, you will see underneath it both the correlation coefficient (r) and the coefficient of determination (r-squared).  You should see that your r value is .84 for this data set.  Just so you know, r can be negative, but r-squared never will be.

20 + 1.25d = 2.50d
20 = 2.50d - 1.25d
20 = 1.25d
20 / 1.25 = d
