In this item, there needs to be a basis as to how many significant numbers can be present in a certain figure. If the answer 327.66 m/s is to be expressed as a 3 significant figures only, the answer would have to be 328. What was done here is to simply round up the units digit of the number since the decimal place (tenths) digit has a value of greater than 4.
The answer to this item is therefore letter B.
The answer is true. The table does show an object moving with changing speed.
Answer:
<h3>6.80kg, 6.70kg and 6.90kg.</h3>
Explanation:
To get the set of measurements that best represents accuracy if the true value is 6.80 kg, we will find the mean of the set of numbers and chech which is equal to 6.80kg
According to the set of data 6.8kg, 6.7kg and 6.9kg
Mean = sum of the number/sa mple size
Sum of the numbers = 6.8+6.7+6.9 = 20.4
sample size = 3
Mean of the set of measurement = 20.4/3
Mean of the set of measurement is 6.80kg
Since the answer is 6.8kg, hence set of measurements that best represents accuracy are 6.80kg, 6.70kg and 6.90kg.
B because your supposed to bike the same direction traffic is going.
