Using hit and trial, you van find it pretty easily-
- Putting x=0, we get y=-3
- Putting x=1, we get y=-1
- Putting x=2, we get y=5
You can try it for yourself as well, for me, I couldn't find any other option appropriate.
Does soil without nitrogen decrease the weight of worms when compared to soil with nitrogen? The weights of 14 randomly selected
worms are taken, 7 in soil with nitrogen, and 7 in soil without nitrogen. The mean weights of worms in soil without nitrogen was 35.3 micrograms, while the mean weights of worms in soil with nitrogen was 36.3 micrograms. A researcher randomized the data over 100 trials, and the difference of means for each trial is shown in the dot plot below. What can the researcher conclude from this study?
a. The difference in weights is not significant because an original difference of means of –1 is very likely
b. The difference in weights is significant because an original difference of means of –1 is not very likely
c. The difference in weights is significant because an original difference of means of –1 is very likely
d. The difference in weights is not significant because an original difference of means of –1 is not very likely
a. The difference in weights is not significant because an original difference of means of –1 is very likely

Answer: 3.2 tons
Step-by-step explanation:
We know that 1 ton = 2000 pound
Then ,
Given : Mustafa’s horse ate 6,400 pounds of hay last year.
Then, the number of tons of hay his horse ate last year is given by :-
Therefore, the number of tons of hay his horse ate last year = 3.2 tons
