Answer:
a) 10 weeks
b) P(k≤2)=0.190
c) P(k>17)=0.167
Step-by-step explanation:
This problem can be solved applying the geometric distribution.
The probability of needing k weeks to find an acceptable apartment can be written as:

a) The expected value of this distribution is:

Answer: 10 weeks
b) The probability of finding an acceptable department in the first 2 weeks is:

c) We have to calculate P(k>17)

Answer:
5.7 + 2.5/10x ≥ 8
where x is the artistic score
Step-by-step explanation:
if the technical score is 7.6/10 = 76% of 75% = 0.57 out of 10.
there are still 2.5 more points that can be obtained, so the gymnast needs 8 - 5.7 = 2.3 out of 2.5 possible points
the inequality would be:
5.7 + 2.5/10x ≥ 8
where x is the artistic score
2.5/10x ≥ 8 - 5.7
2.5/10x ≥ 2.3
x ≥ (2.3 x 10) / 2.5
x ≥ 9.2
