Answer:
- 4
Step-by-step explanation:
The average rate of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ - 2, 2 ]
f(b) = f(2) = 9 ← from table value of f(x) for x = 2
f(a) = f(- 2) = 25 ← from table value of f(x) for x = - 2, thus
average rate of change = =
= - 4
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
