Average speed would be 7 over 20 why it is because I turned both of the fractions into decimals and then I got 1.75 over 0.5 u would divide and it would give you 3.5 then I turned it back to a fraction multiplying it by a 100 gives us 35 over 100 then you simplify it by dividing both denominator and numerator by 5 would give you 7 over 20
Answer:
0.67
Step-by-step explanation:
z = (x-μ)/σ, where
x is the raw score = 5.6 seconds
μ is the population mean = 5.2 seconds
σ is the population standard deviation = 0.3 seconds
z = 5.6 - 5.2/0.3
z = 0.66667
z score is approximately 0.67
The z-score for a player who runs a time of 5.6 seconds is 0.67
