Answer:
672.
Step-by-step explanation:
First find the prime factors:
112 = 2*2*2*2*7
96 = 2*2*2*2*2*3
There are 4 pairs of duplicate 2 's in the factors, so the LCM = 2*2*2*2*2*3*7
= 672 (answer).
Note: the duplicates only appear once in the calculation of the LCM.
Answer:
0.2381 = 23.81%
Step-by-step explanation:
To calculate this probability, we can calculate the probability of each student of the 3 students interviewed being from middle georgia state college.
If inicially there are six students from middle georgia state college among the nine students, the probability of the first student chosen being from middle georgia state college is 6/9.
Then, as one student was already picked, we have now 5 students from middle georgia state college in a total of 8 students, so the probability of the second student will be 5/8.
In the same way, the third student will be picked in a group of 7 students, where 4 are from middle georgia state college, so the probability is 4/7.
Multiplying all the probabilities, we have the probability of all three students interviewed being from middle georgia state college:
P = (6/9) * (5/8) * (4/7) = 120/504 = 0.2381 = 23.81%
You would change 22 to a decimal which would be .22 then multiply that by 900 which would be 198. So she spent 198 dollars on the phone
