Will measured the diameter of a penny as 1.9 cm using the ruler. what is the margin of error? 1.5 cm to 2.0 cm 1.5 cm to 2.5 cm 1.85 cm to 1.95 cm 1.90 cm to 1.95 cm

Hence, the margin of error is:

1.85 cm to 1.95 cm

Step-by-step explanation:

It is given that:

Will measured the diameter of a penny as 1.9 cm using the ruler.

" Now we know that the margin of error is a statistic expressing the amount of random sampling error in a survey's results "

It is an amount (usually small) that is allowed for in case of miscalculation or change of circumstances.

So here we have the margin of error to be:

1.85 cm to 1.95 cm

( since the value of change to the left and right of 19 is same and is small (it is 0.05)

i.e. 1.9-0.05=1.85 cm

and 1.9+0.05=1.95 cm ).

Margin of error is: ± 0.05.

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
