The ages of several trees on school property are shown below: 3 years, 8 years, 10 years, 14 years, 11 years what is the mean age of these trees?
2.8 years
9.2 years
10 years
11 years

The mean age of these trees is 9.2 years.

Step-by-step explanation:

The mean is calculated as the sum of the observations (the sum of trees’ ages in this case) divided by the number of observations (five trees in this case). The formula is X = (∑Obs) / n, where X means the mean value, ∑ means the sum, Obs means the value of the observations (trees’ years), and n means the number of observations (5).  

X = (∑Obs) / n  

X = (3+8+10+14+11) / 5  

X = 46 / 5

X = 9.2 years

step-by-step explanation:

just count the values of x & y of the vertex of the graph and see how many units in the x and y direction will get you from the f(x) graph to the f(x) graph

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
