For a science experiment Ella recorded the time, in seconds, to boil 650 grams of solution. Her results were 24.5, 23.2, 29.8, and 30.1. Find the mean, in seconds, of the boiling times.

Mean of boiling times = 26.9 seconds

Step-by-step explanation:

Times ella recorded are given as;

24.5 seconds, 23.2 seconds, 29.8 seconds, and 30.1 seconds.

Now, we want to find the mean of these boiling times.

Formula for mean is;

Mean = sum of terms/number of terms

In this question,

number of terms = 4

Sum of terms = 24.5 + 23.2 + 29.8 + 30.1 = 107.6

Thus,

Mean = 107.6/4

Mean = 26.9 seconds

why do wages differ across industries

step-by-step explanation :

micro economists are concerned with economics on an industry or individual firm basis.

macro economists are concerned with national and international level

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
