Greg is testing two different types of fertilizer on his tomato plants to find the best conditions for his summer garden. He is
adding different amounts of fertilizers to his plants. Then he is recording how much the plants grow for 4 weeks. His data is
recorded in the data table.
In this experiment, the independent variable is the amount of fertilizer applied (Types A and B); the dependent variable is
the plant growth. What is the result when the independent variable is changed? Can you match these situations?
Both Fertilizer A and B
1.5kg fertilizer A
Expected results would be very low average weekly plant growth, <0.2cm
Increase in average weekly plant growth, increase fertilizer 1kg to 1.5kg
Results in the greatest weekly growth overall
Results in the least weekly plant growth overall
2.5kg fertilizer B
3.0kg fertilizer A or B

da freeck kinda math is this just drop out

step-by-step explanation:

their is no graph showing

step-by-step explanation:

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
