Step-by-step explanation:
A factor is an independent variable that is manipulated in an experiment.
Every factor has two or more levels, which are different values of the factor.
A combination of factor levels is called a treatment.
There is one factor: number of jumps.
This factor has two levels: sets of 10 and sets of 20.
For a single factor experiment, the levels are also the treatments: Jump 10 program and Jump 20 program.
Answer:
2:10 2/10 2 to 10 10:2 10/2 10 to 2 12:1 12/1 12 to 1
Step-by-step explanation:
The probability that a plant in the experiment receives visible or ultraviolet light is 7/10.
<u>Step-by-step explanation</u>:
The total number of plants in the experiment = 30 plants
Plants that receive visible light alone = 12 plants
Plants that receive ultraviolet light alone = 15 plants
Plants that receive both visible and ultraviolet light = 6 plants
<u>step 1</u> :
<em>Probability = No. of required events / Total number</em>
<u>step 2</u> :
P(visible) = 12 / 30
P(ultraviolet) = 15 / 30
P(both) = 6 / 30
<u>step 3</u> :
P(visible or ultraviolet) = P(visible) + P(ultraviolet) - P(both)
= 12/30 + 15/30 - 6/30
= 21/30
P(visible or ultraviolet) = 7/10
