Answer:
A.The modes differ by 40 and the ranges differ by 40.
Step-by-step explanation:
The mode of a data set is the value that occurs most often.
For the data from last summer, the value 190 is in the list twice, while all other values are only in once. This means 190 is the mode.
For the data from this summer, the value 150 is in the list twice, while all other values are only in once. This means 150 is the mode. This also means the difference in modes is 190-150 = 40.
The range is the difference between the maximum and minimum values in a data set. For last summer's data, the maximum is 220 and the minimum is 140; this gives us 220-140 = 80 for the range.
For this summer's data, the maximum is 190 and the minimum is 150; this gives us 190-150 = 40 for the range. This means the difference in ranges is 80-40 = 40.

Answer:
|0.254 ≤ p ≤ 0.286|
Step-by-step explanation:
Given that:
In a made up poll :
Proportion of people who like dark chocolate than milk chocolate (p) = 27%
Margin of Error = 1.6%
Hence,
p ± margin of error
27% ± 1.6%
(27 - 1.6)% ; (27 + 1.6)%
25.4% ; 28.6%
0.254 ; 0.286
Therefore ;
Lower bound = 0.254
Upper bound = 0.286
Expressing p as an absolute value Inequality ;
|0.254 ≤ p ≤ 0.286|
Answer:
The concentration of salt in the tank approaches 
Step-by-step explanation:
Data provide in the question:
Water contained in the tank = 8000 L
Salt per litre contained in Brine = 35 g/L
Rate of pumping water into the tank = 25 L/min
Concentration of salt 
Now,
Dividing both numerator and denominator by 
, we have
Here,
The concentration of salt in the tank approaches
