I would say that the results of the study are not significant. This is because the difference of those who drink tea and did not drink tea is small and more or less will have the same values at some points of the research. Having a difference of 0.024, cannot really say anything or differentiate the two.
Answer:

Step-by-step explanation:
We are given that A rose garden can be planted for $4000.
The marginal cost of growing a rose is estimated to $0.30,
Let x be the number of roses
So, Marginal cost of growing x roses = 
Total cost = 
So, Cost function :
---A
Now we are given that the total revenue from selling 500 roses is estimated to $875
So, Marginal revenue = 
Marginal revenue = 
Marginal revenue =
Marginal revenue for x roses = 
So, Revenue function =
----B
Profit = Revenue - Cost

---C
Now Plot A , B and C on Graph
-- Green
-- Purple
--- Black

Answer: 1999 perfect squares between 1,000,000 and 9,000,00
Step-by-step explanation:
Sq root of 1,000,000 is 1000 and square root of 9,000,000 is 3000
Hence there are squares of 1001 to 2999 I. e. 1999 perfect squares between 1,000,000 and 9,000,00
There was 10 friends because there if you times 2/3 by 6 you get 12/18 and 10 people eat it then there is 3/18 left and after you simpfly it you get 1/6
26×4=104
292-104=188
26÷2=13
188-13=175cm
the tree was 175cm when he moved in
