Asmall café sels cups of iced coffee and keeps a record of the number of cups sold over each thrd (a fourimonth period) during 2014, 2015 and 2016· the results-re shown in the table below. t 6 1 plot a graph which shows the sales and the moving averages. draw a line of best fit through the moving averages. this should be b) l11 c) done by eye (ie. there is no need to find the equation of the line of regression). use your line of best fit to estimate the next moving average. the first third of 2017. t 2 1 d) e) use your answer to part [d] to predict the number of cups sold during l1.1 131

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

he kicked it up? is this the answer ?

step-by-step explanation:

(8+64)^2= 5184 < answer

step-by-step explanation:

2^3 = 8

4^3= 64

(8+64)^2 = 5184

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
