Answer:
the standared deviation =2.87 so it is small
Step-by-step explanation:
to calculate the standard deviation of those numbers:
1- Work out the Mean (the simple average of the numbers)
(7+6+5+8+9+1+0+4+3+2)/10=4.5
Then for each number: subtract the Mean and square the result.
[(7 - 4.5)^2 + ... + (2 - 4.5)^2]/10=8.25
√8.25=2.87≅3

Answer:
y = 7x
y = 5.5x
Sophia
Step-by-step explanation:
Given that:
Aisha runs 1 km in 7 minutes :
Aisha's function :
y = 7x
x = number of kilometers and y is the number of minutes
For Sophia :
Slope = change in y / change in x = (15.5 - 10) / (1 - 0)
Slope = 5.5
Hence, Sophia :
y = 5.5x
Hence, Sophia runs faster as she completes one kilometer in 5.5 minutes. Which is lesser Than Aisha's time. Of 7 minutes.
