Answer:
17
Step-by-step explanation:
To obtain the tenth term, substitute n = 10 into the n th term formula, that is
n + 7 = 10 + 7 = 17 ← tenth term
Neither ! X= -9/4 and Y=9
Answer: The required probability is 0.82.
Step-by-step explanation:
Since we have given that
Number of projects = 3
So, probability of getting each project = 
Probability of first path being completed in 43 days = 0.7
Probability of second path being completed in 43 days = 0.85
Probability of third path being completed in 43 days = 0.90
So, Probability that the project will be completed on time would be

Hence, the required probability is 0.82.
Answer:
Step-by-step explanation:
The smallest angle is opposite to the smallest side.
<u>Use the law of cosines to find the angle opposite to side with the length of 10 cm:</u>
- cos A = (b² + c² - a²)/(2bc)
- cos x = (11² + 13² - 10²)/(2*11*13)
- cos x = 190/286
- cos x = 0.664 (rounded)
- x = arccos (0.664)
- x = 48.4° (rounded)
