Ahomeowner has 5 cherry tomato plants in her garden. over the course of the season the yields (in pints of tomatoes per plant) are: plant 1 2 3 4 5 yield 4 3.5 4.5 4.2 3.8 what is the average yield per plant, and what is the standard deviation (to two decimal places)?

The average yield per plant is 20 and the standard deviation is 16.002

Step-by-step explanation:

Given: A homeowner has 5 cherry tomato plants in her garden. Over the course of the season the yields (in pints of tomatoes per plant) are:

Plant      Yield

1                  4

2                 3.5

3                 4.5  

4                 4.2  

5                 3.8

To Find: What is the average yield per plant, and what is the standard deviation (to two decimal places)?

Solution:

Average yield per plant =

                                        =

                                        =

So,

Standard deviation=

Hence the average yield per plant is 20 and the standard deviation is 16.002

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
