Suppose that an auditor is auditing the financial transactions of ABC Company. There are 4000 sales invoices that require auditing. The auditor grouped the invoices into three groups as small transactions (group 1), medium transactions (group 2) and large transactions (group 3). Group 1 contains 1000 invoices, group 2 contains 1500 invoices and group 3 contains 1,500 invoices. The researcher wants to select 20% of invoices from each group.

step-by-step explanation:

negitive slope

it is c, trust i got your back lol

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
