Sorry but i dont know the right answer
Answer:
Step-by-step explanation:
The interquartile range is the difference between Q3 and Q1.
Since Q3 = 75% mark and Q1 = 25% mark, this range is representing the data between those 2 marks:
The blank is 50%
When you round to the nearest hundredth, you round to two numbers after the decimal place
So the answer is 80.16
The 5 becomes a 6 because the number after it (9) is larger than 5
Hope this helps
Its called translation. Translation is the shifting (no rotating) os an object from one point to another.
Answer:
<em>The decay rate 'm' is 0.25</em>
Step-by-step explanation:
As given,
Average Life time of New cell phone = 4 years
Lifetime of phone = L = ?
<em>L</em><em> is a random variable defining lifetime of a cell phone.</em>
L∼
Exponential (m)
Mean of Exponential Distribution = ![\frac{1}{m}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bm%7D)
As, they follow exponential distribution, so to find decay rate , we simply can write it as :
= 4
or
![m = \frac{1}{4}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B1%7D%7B4%7D)
<em><u>m=0.25</u></em>
L∼
Exponential (0.25)
<em>The decay rate is 0.25</em>
