Answer:
4.53
Step-by-step explanation:
Given the data :
4, 5, 10, 11, 15
The mean = 9
The standard deviation of a sample :
s = √[Σ(x - mean)²/(n-1)]
s = √[((4-9)² + (5-9)²+(10-9)² + (11-9)² + (15-9)²) / (5-1)]
s = √(25+16+1+4+36)/4
s = √20.5
s = 4.527
s = 4.53
Use the pythagoras theorem to find the number of blocks between Shakillah's and Reyna's house
= sqrt (12^2+ 5^2) = aqrt 169 = 13 blocks
distanc,e from school to Shaquilla's house = 12 - 0 = 12 blocks
.. .. .. .. .. ... .. Reyna's house = 5 -0 = 5 blocks
So total number of blocks in entire trip = 5 + 12 + 13 = 30
