Answer:
The number of persons entering the bank based on given 20 simulations are 12
The number of persons exiting the bank based on given 20 simulations are 8
We have to find the probability that she will see a person entering the bank.
The probability that she will see a person entering the bank is:
![\frac{12}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B20%7D)
![0.6](https://tex.z-dn.net/?f=0.6)
Therefore, the option 0.600 is correct.
Answer:
c 12.6 inches
Step-by-step explanation:
radius = diameter/2 =4/2 =2 inches
circumference = 2πr
= 2× 22/7 × 2 = 12.6 inches
1.) 2=50%
2.) 25% of 30,000= 7500
Answer:
tanA=34⟹sinA=332+42−−−−−−√=35
Now, we have
sinAcosA=tanA
⟹3/5cosA=tanA
⟹cosA=13×54×3
⟹cosA=45
⟹cosAsinA=4×35×5=1225
