Answer:
28 beads were used to make the bracelet. 7 beads were not yellow.
Step-by-step explanation:
3/4 beads used to make the bracelet are yellow
If 21 beads are 3/4 of the bracelet and yellow
1/3 of the 21 beads would be 1/4 of the bracelet
7 beads are 1/3 of 21 beads
7 × 4 = 28 beads
The standard deviation is the square root of the variance
so if the variance is 256, then the standard deviation is : sqrt 256 = 16 <==
