a.
is a proper joint density function if, over its support, is non-negative and the integral of is 1. The first condition is easily met as long as . To meet the second condition, we require
b. Find the marginal joint density of and by integrating the joint density with respect to :
Then
c. This probability can be found by simply integrating the joint density:
Answer:
B
Step-by-step explanation:
I don't know but I know it's b I think so
Company 1: (24 + 26 + 28 + 23 + 21) / 5 (this is how many numbers added together) = 24.4
Company 2: (6 + 32 + 9 + 31 + 21) / 5 = 19.8
Company 3 (15 + 15 + 15 + 15 + 15) / 5 = 15
Company 4: (13 + 10 + 45 + 12 + 15) / 5 = 19
Company 1 has the longest average commute time per employee.
Answer:
75.398223
Step-by-step explanation:
Circumference Formula: 2πr or dπ ⇒ r=radius and d=diamater
1.) π≈3.14
2.) 24×3.14=75.36
