Answer:
Two intervals are 63 and 75
Step-by-step explanation:
Given:
Mean of students (μ) = 69 inches
Standard deviation (σ) = 3 inches μ
Find:
Interval of heights (95%) using empirical rule
Computation:
Interval of heights (95%) using empirical rule:
⇒ μ – 2σ = 69 - 2(3)
⇒ μ – 2σ = 69 - 6
⇒ μ – 2σ = 63
⇒ μ + 2σ = 69 + 2 (3)
⇒ μ + 2σ = 69 + 6
⇒ μ + 2σ = 75
Two intervals are 63 and 75
Answer:
AC and DF
Step-by-step explanation:
We can see that the triangles have a scale factor of 3.
1 * 3 = 3 (AB and DE)
2 * 3 = 6 (BC and EF)
However...
2 * 3 = 6 not 7 (AC and DF)

The logarithmic form of 13² = 169 is ㏒₁₃ 169 = 2
<h3>How to determine the logarithmic form</h3>
Using the logarithmic rule , we have that
㏒ₙn = bⁿ
Given 13² = 169
It is important to note that it can be written either in the logarithmic form or in the index form.
In this case, we have written in the index form as .
㏒₁₃ 169 = 2
Thus, the logarithmic form of 13² = 169 is ㏒₁₃ 169 = 2
