Divide and then multiply by 100
In this case the chords are congruent.
x = 7 + 7 = 14
Answer:
7 years (This answer is to the nearest year)
Step-by-step explanation:
The way you could work this out is by trial and error. 11 % a year means that its population increases by 4400 annually. 40,000 X 1.11^1 gives you the amount it would be after one year (44000). I got the 1.11 because of the percentage (0.11) plus the amount you need to do percentage increase (1). Then all you do is keep on going up till you hit the number you need (80,000) after about 7 years the total would have hit 80,000 and would have actually went past it (83046)

Answer:
The z score for the airplane arriving 13 minutes after arrival time is 0.33
Step-by-step explanation:
Using normal distribution,
The average lateness for one of the top airline companies is 10 minutes. So our mean, u = 10
The variance, s of the lateness measure is calculated as 9.
x =13 which stands for arrival time.
Using normal distribution,
z = (x - u)/s
z = (13 - 10)/9 = 3/9 = 0.33
The z score for the airplane arriving 13 minutes after arrival time is 0.33. The probability value of the z score can be found by looking at the Normal distribution table
