math help please?
1. You should draw a line of best fit for a scatter plot if there is no correlation among the data points.
true or false???
help im desperate
2. You have to spend on x candles and y batteries for your hurricane supplies. Candles cost .00 each and a pack of C batteries cost .50 each. Write an equation in standard form to represent your purchase of these supplies.
A. 6.5y = 3x + 25
B. y = x + 25
C. 3x + 6.5 y = 25

there is no line of best fit if there is no correlation.
as for the other question, you have 25$ = 3x + 6.5y
thats it.
C is false 3x=6.5y=25
1. False
2. 25 = 3x + 6.5y
1. If there is no correlation, then you can’t draw a line of best fit. There is no line of best fit for a graph of (for example) hai length against maths test results
2. It is C. 25 is the total amount of money you have to spend so that must equal to the number of candles and number of batteries you buy.
1. I think its False.
2. Its C.
Hope it helps!!
