Find the missing element in the following base rate percentage problem 12% of what number is 42

If a variable has a distribution that is bell-shaped with mean 28 and standard deviation 5, then according to the Empirical R

mars1129 [50]

Answer:

99.7% data lies between 13 to 43

Step-by-step explanation:

Mean: $\mu = 28$

Standard deviation : $\sigma = 5$

68% of data lies between $\mu - \sigma$ to $\mu +\sigma$

95% of the data lies between $\mu - 2\sigma$ to $\mu +2\sigma$

99.7% data lies between $\mu - 3\sigma$ to $\mu +3\sigma$

We are supposed to find 99.7 of the data will lie between which values

99.7% data lies between $28 - 3(5)$ to $28 +3(5)$

99.7% data lies between 13 to 43

Hence 99.7% data lies between 13 to 43

Explain how the Venn diagrams in this lesson show that all integers and all whole numbers are rational numbers

Vinvika [58]

The Venn diagram shows that rational numbers include all integers (-3, -2, -1, 0, 1, 2, 3,) and all whole numbers (0, 1, 2, 3, 4, 5). Inside the rational numbers circle is the integer circle, and the whole numbers circle, which concludes that all integers and whole numbers are rational numbers.
