Answer:
The probability that a randomly selected boy in secondary school can run the mile in less than 302 seconds is 0.0107
Step-by-step explanation:
Consider the provided information.
It is given that mean is 440 seconds and standard deviation is 60 seconds.
z factor for less than 302 seconds would be:
z = (302 - 440) / 60 = -2.3
The probability of getting a z factor of less than -2.3 = 0.0107 approximately.
looking up in the z-table for a z factor of -2.3.
The probability of a student running the mile in less then 302 seconds would be 0.0107.
Hence, the probability that a randomly selected boy in secondary school can run the mile in less than 302 seconds is 0.0107
From 7:00 to 9:46 we see it passes 2 hours and 46 minutes.
But it started 6:58 . So we add +2 minutes. 46+2 = 48
2 hours and 48 minutes.
But we must find the second form.
1 hours = 60 minutes = 3600 seconds
So, 2 hours = 120 minutes = 7200 seconds.
and 1 minutes = 60 seconds
48 minutes = 60 x 48 = 2880 seconds.
7200 + 2880 = 10080 seconds.
