Imelda got a score of 98,16,17,89,22,14,21,34,56 in her last quiz in midterm. What is her average score?

Answer 1

$$98,16,17,89,22,14,21,34,56$$

$$\bar{x}=\dfrac{1}{n}\displaystyle\sum_{i=1}^nx_i$$

$$\bar{x}=\dfrac{1}{9}(98+16+17+89+22+14$$

$$+21+34+56)=\dfrac{367}{9}\approx40.8$$

Her average score is 40.8.
