Answer:
Step-by-step explanation:
answer is c
Any triangle where the sum of the angles is over or under 180 cannot exist.
A 45-55-80 triangle can exist, but a 45-55-90 triangle cannot.
A 30-45-105 triangle can exist, but a 80-90-105 triangle cannot.
When x=1
z=1/3
When x=13
z=1/3 x 13
z= 13/3
z= 4 1/3
BRAINLIEST PLS!!!
From my research, the available data in the problem is as follows:
<span>No. of Heads | Probability
0 1/16
1 4/16
2 6/16
3 4/16
4 1/16
To calculate the average amount spent by a student in an hour:
[(0 * 1/16) + (1 * 4/16) + (2 * 6/16) + (3 * 4/16) + (4 * 1/16)] * 2
= 4
Therefore, the library earns $4 per student each hour</span>
