PLS MARK AS BRAINLIEST !!!

2058

Step-by-step explanation:

Mean enrolment = (sum of all x)/(No. of x)

Mean enrolment = (1555 + 1670 + 1750 + 2013 + 2540 + 2820)/6

                            = 12348/6

                            = 2058

Answer 2

$\bigstar$ Given:

• Enrolment of a school during six consecutive years = 1555, 1670, 1750, 2019, 2540, 2820

$\bigstar$ To Find:

• Mean enrolment of the school for this period.

$\bigstar$ Solution:

The mean enrolment = $\sf\frac{Sum\: of\: the\: enrolments\: in\: each\: year}{Total\: number\: of\: years}$

The mean enrolment = $(1555 + 1670 + 1750 + 2019 + 2540 + 2820)$ ÷ $6$

$\implies 12354$ ÷ $6$

$\implies \boxed{\underline{\underline{2059}}}$

Thus, the mean enrolment of the school for the given period is 2059.
