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 =
As, they follow exponential distribution, so to find decay rate , we simply can write it as :
= 4
or
<em><u>m=0.25</u></em>
L∼
Exponential (0.25)
<em>The decay rate is 0.25</em>
Answer:
Step-by-step explanation:
P(less than 6) = 2/5
Ok so the numbers are in a sequence of +3 so he would go 2,5,8,11,14. He could only have 5 groups of marbles because 2+5+8+11+14=40
