The simplified form is 4m^5
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.
To find<span> the </span>cube root of a number<span>, you want to </span>find <span>some </span>number<span> that when multiplied by itself twice gives you the original </span>number<span>. In other words, to </span>find <span>the </span>cube root<span> of 8, you want to </span>find<span> the </span>number<span> that when multiplied by itself twice gives you 8. The </span>cube root<span> of 8, then, is 2, because 2 × 2 × 2 = 8.</span>
Answer:
<h2>89.5°</h2>
Step-by-step explanation:
Using the vector formula
|u| = magnitude of vector u
|v| = magnitude of vector v
u.v is the dot product of vector u and v
Given |u| = 88, |v| = 99 and u.v = 77, to get we will substitute the given values into the equation above;
