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:
-8/7p=c
Step-by-step explanation:
add 9p to both sides of the equation
then divide both sides by 7

Answer:
3.5
Step-by-step explanation:
The formula for the pH of a solution of hydronium ions is given by the logarithmic equation pH=-log [H3O+], where [H3O+] is the hydronium ion concentration. Find the pH of a certain agricultural product with the hydronium ion concentration of 3.2 x 10^-4
We have the Logarithmic equation
pH=-log [H3O+],
We have the hydronium ion concentration = 3.2 x 10^-4
Hence,
pH = - log[3.2 × 10 ^-4]
pH = 3.4948500217
Approximately
pH = 3.5
Therefore, the pH of a certain agricultural product with the hydronium ion concentration of 3.2 x 10^-4 is 3.5
Hey there!
2 3/4 * 3 1/4
≈ 11/4 * 13/4
≈ 11(13) / 4(4)
≈ 143/16
≈ 8 15/16
Thus, the answer should be: 8 15/16
Good luck on your assignment & enjoy your day!

Answer:49+2m
Step-by-step explanation:
49+2m
Increase,another way to say addition
Twice means “two times”
A number would be a variable since it’s unknown
