Answer:
6.27
Step-by-step explanation:
We are to obtain the standard deviation of the given values :
{24, 18, 31,25, 34}
The standard deviation = √(Σ(x - mean)²/ n)
The mean = (ΣX) /n
Using calculator to save computation time :
The standard deviation, s = 6.27 (2 decimal places)

Step-by-step explanation:
Petra can make 8 costumes with 12 yards of fabric
<h3><u>Solution:</u></h3>
Given that Petra was given 12 yards of fabric to make costumes for the school play
Each costume requires yards
<em><u>To find: number of costume Petra can make</u></em>

Total fabric she has = 12 yards
Fabric needed for 1 costume = yards
Therefore,
Thus petra can make 8 costumes with 12 yards of fabric
