Answer:]
At least 75% of the eruptions lasted between 1.24 and 5.6 minutes.
Step-by-step explanation:
We are given the following information in the question:
n = 32
Mean = 3.42
According to Chebyshev's rule:
At least , percent of data lies within , where s is the standadrd deviation of the data and is the mean of data.
For k = 2, we have
75% of data lies within the range of
Thus, at least 75% of the eruptions lasted between 1.24 and 5.6 minutes.

Answer: -12y²+7y²+20y-7
Step-by-step explanation:
Here, we need to use the concept of the FOIL method
----------------------------------------------------------
Given
(-3y+1)(4y²-y-7)
Expand Parenthesis using FOIL
-12y³+3y²+21y+4y²-y-7
Put like terms together
-12y³+(3y²+4y²)+(21y-y)-7
Combine like terms together
-12y²+7y²+20y-7
Hope this helps!! :)
