Can you please help me i dont know the answer. percent error question

Step-by-step explanation:

This is actually a tough question, but only because you need to be told how your instructor wants it to be done. The way I did it was

(What you should get - what you got) * 100    

                         = % error

What you should get

What you should get is 1.8

What you got should be 1.7

(1.8 - 1.7) * 100 / 1.8

.1 * 100 / 1.8

10 / 1.8 = 5.56%

Note: what really makes this difficult is whether you allow for a negative experimental error or not. Sometimes it is the absolute value taken as the difference. Sometimes it is taken as (the experimental value - accepted value) / accepted value.

In this case the answer might be - 5.56%. You have to check your notes to get the correct answer according to the field of study.

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
