Answer:
I believe this is SSA congruence
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
Answer:
z=10
Step-by-step explanation:
We have to find the value of z.
(3×22)-(3×5)= 66-15= 51
Now,
51=4z+11
4z=51-11
z=40/4
z=10
Hope this helps you :)
8 and 9
9^3-8^3
729-512
=169
If you meant to say
(-5) + (20)
Then the answer is 15
Since you can rearrange it to be
(20) - (5)
= 15
