Due gruppi di studenti misurano la lunghezza di una sbarra e forniscono i seguenti risultati: l1= 1,450 m , l2= 1,45 m Quale dei due gruppi ha eseguito la misura con una maggior precisione? Ipotizzare quale possa essere stata la sensibilità degli strumenti utilizzati dagli studenti nei due gruppi?

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

answer: the answer is b. i think hope i got it correct

step-by-step explanation:

i believe it's a.

i'm not sure on this one, most likely correct.
