The difference is referring to subtraction, so the question was most likely something like how much longer is this butterflies wings than this ones. so 4.55 might be one of the lengths and 3 might be the other, so 4.55 - 3 is 1.55.

Answer:
60 students
Step-by-step explanation:
The confidence interval of a proportion is given by:

Where 'p' is the proportion of students who responded 'yes', 'z' is the z-score for a 95% confidence interval (which is known to be 1.960), and 'n' is the number of students in the sample.
If the confidence interval is from 0.584 to 0.816, then:

60 students were in the sample.
8.333333 reoccurring. 1 divided into 6 is 1.666667. Multiply by the remaining amount, 5? Idk
Step-by-step explanation:
Plan A: A = 20G
Plan B: B = 15G + 40
To see when they will be equal set the equations equal to each other
20G = 15G + 40
5G = 40
G = 8
At 8 GB they will cost the same amount.
20(8) = $160
15(8)+40 = $160
Hope it will be Helpfull
thank you
