Answer:
45
Step-by-step explanation:
90+45=135 180-135 is 45
Answer:
a. Expected frequency of losses per semester = 0*0.08 + 5*0.16 + 10*0.28 + 15*0.32 + 20*0.14 + 25*0.02
Expected frequency of losses per semester = 11.7 losses per semester
b. Variance = (0-11.7)²*0.08 + (5-11.7)²*016 + (10-11.7)²*0.28 + (15-11.7)²*0.32 + (20-11.7)²*0.14 + (15-11.7)²*0.02
Variance = 10.9512 + 7.1824 + 0.8092 + 3.7848 + 9.6446 + 3.5378
Variance = 35.61
c. As losses equal $60, expected losses per semester = 11.7*$60 = $702
d. Expected losses of all textbooks per semester = 250*11.7*$60 = $175,500
You ran approximately 5278 feet. This question only involving converting units. 1 mile=1.609km=1609m. 1m=3.28 feet. So 1 mile=1609*3.28=5278 feet approximately.
you need to include what equation is given
The answer is always all the numbers added together
with the what they are specifically asking in front.
if that makes sense?
3:14
they are asking for the red so 3 goes in front and the total number of all the paper clips follows
