So if you know that 10 skeins makes 4 scarves... then 20 skeins makes 8 scarves (because you doubled it)

and if 10 skeins make 4 scarves... then half that number of skeins should make half the number of scarves... so 5 skeins makes 2 scarves

So we know that 20 skeins makes 8 scarves and 5 skeins make 2 scarves... all we have to do is add up the skeins and find we get 10 scarves

Students in the science lab are measuring the mass of an object on a triple beam balance. The object has a mass of 38 grams. Complete the table below with the absolute and percent error for each students’ measurement. Round your answer to the nearest tenths place.

Answers

Answer:

The answer is 40

Step-by-step explanation:

have a nice day!

The absolute error of Danielle, Iris, and HB is 2,6 and 1 gram respectively. The percentage error of Danielle, Iris, and HB  are 5%,15%, and 2.5%  respectively.

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Actual mass = 38

Danielle error = 40 - 38 = 2 grams

% error = 2/40 x 100 = 5%

Iris error = 4 - 34 = 6 grams

% error = 6/40 x 100 = 15%

HB error = 41 - 40 = 1 grams

% error = 1/40 x 100 = 2.5%

Hence "The absolute error of Danielle, Iris, and HB is 2,6 and 1 gram respectively. The percentage error of Danielle, Iris, and HB  are 5%,15%, and 2.5%  respectively".

Step-by-step explanation:

If you graph out the points on a line, you can clearly see that the rise between the points on the graph is 2, while the run is 4. This would give you [tex]\frac{2}{4}[/tex], so if you simplify the fraction, you would get [tex]\frac{1}{2}[/tex].
