Step-by-step explanation:
=3(2+c)-2(c-5)
=6+3c-2c+5c
=6+6c
=6(1+c)
hope it helps.
83°?
- SS postulate, 2 sides of triangle r equal, meaning 3rd is most likely equal I think.
- so all angles r equal
- all interior angles r congruent. so r exterior
180 - 97 = 83
Answer:
0
Step-by-step explanation:
3√128-2√6x4√3
= 3√2√64 - 2√6 x 4√3
= 24√2 - 2√6 x 4√3
= 24√2 - 8√18
= 24√2 - 8√2 * √9
= 24√2 - 3* 8√2
= 24√2 - 24√2
= 0
By knowing we can expand and simplify,
.
Hope this helps.
Answer:
P=0.2613
Step-by-step explanation:
-Notice that this is a poison probability distribution problem.
-The Poisson probability function is expressed as:
where:
- x=0,1,2,3
- Euler's constant
- =mean number of occurrences.
Given that x= 2 and , the probability is calculated as:
Hence, the probability that in a randomly selected office hour, the number of student arrivals is 2 is 0.2613
