The unit price or unit rate is $2
Let y represent the price of tomatoes, then the price of x tomatoes is
dollars.
This represents a direct variation.
This equation is of the form 
, where k=2 is the constant of proportionality.

Answer:
The Null hypothesis is a claim the researcher is trying to disprove. (I think)
Step-by-step explanation:
The null hypothesis states that there is no relationship between the two variables being studied (one variable does not affect the other). It states results are due to chance and are not significant in terms of supporting the idea being investigated.
1. A = ¹/₂bh
A = ¹/₂(25)(4)
A = ¹/₂(100)
A = 50 yd²
3. A = ¹/₂bh
A = ¹/₂(3)(1)
A = ¹/₂(3)
A = 1¹/₂ cm²
