Question

two students weighed a 125 ml beaker that had a mass of 80.562g on a calibrated top-loading balance, recorded three mass readings for the beaker, then determine the average. ​

Answer 1

Answer:

60g/cm - 78grams . 2560ml

Step-by-step explanation:

Answer 2

The average of a dataset is the sum of the dataset divided by the count of the dataset.

The average mass readings of students A and B is 80560g

Given that:

$Student\ A: 80,560\ 80,555\ 80,565$

$Student\ B: 80,400\ 79,551\ 81,729$

The average mass is calculated using average formula

$\bar x = \frac{\sum x}{n}$

For both students

$n = 3$ --- the number of mass readings

So, we have:

Student A

$\bar x_A = \frac{80560 + 80555 + 80565 }{3}$

$\bar x_A = \frac{241680}{3}$

$\bar x_A = 80560g$

Student B

$\bar x_B = \frac{80400+ 79551+ 81729}{3}$

$\bar x_B = \frac{241680}{3}$

$\bar x_B = 80560g$

Hence, the average mass readings of both students is 80560g
