Answer:
The value of the parameter is λ is 0.03692
Step-by-step explanation:
Consider the provided function.
for −∞ < x < ∞.
It is given that standard deviation is given as 38.3 km.
Now we need to calculate the value of parameter λ.
The general formula for the probability density function of the double exponential distribution is: 
Where μ is the location parameter and β is the scale parameter.
Compare the provided equation with the above formula we get.
and μ = 0.
Standard deviation = √2β
Now substitute the value of β in .
Hence, the value of the parameter is λ is 0.03692

<u>Answer:</u>
243 students are involved in either sports or music whereas 100 are not
involved in either of it.
<u>Step-by-step explanation:</u>
No. of students who are in music = 115
No. of students who are in sports = 197
No. of students who are in both activities = 69
So, no. of students who are involved either in sports or music,
= (115 + 197 - 69)
=243
So, no. of students who are not involved in either sports or music,
= (343 - 243)
=100

Answer:
A 8 hours
Step-by-step explanation:
Last week she baby sat 12 hours.
This week she baby sat x hours.
Last week she baby sat 1 1/2 times as many hours as this week.
12 = 1 1/2 × this week
12 = 1 1/2 × x
1.5x = 12
x = 12/1.5
x = 8
Answer:
A 8 hours
