Answer:

Margin of error is 4.1

Step-by-step explanation:

The margin of error in statistics refers to a quantity which expresses the amount of random sampling error from the results of a survey conducted. A large margin of error implies less confidence in the results of the survey.

The margin of error can be approximated using the population standard deviation, if known.

Therefore, the margin of error will be reported as 4.1

Answer:

50 grams

Step-by-step explanation:

Let the amount of cheese required by the recipe be "x"

Ann increased 60% from original amount and then used up 80 grams. Thus:

Original, increased by 60%, became 80

This translated to algebraic equation would be:

x + 0.6x = 80

Note: 60% = 60/100 = 0.6

So we can solve the above equation for "x" and get our answer. Shown below:

$x + 0.6x = 80\\1.6x=80\\x=\frac{80}{1.6}\\x=50$

Hence,

the recipe required 50 grams of cheese
