<span>19 sheep have 3 lambs each means 19x3=57 lamps
Plus
</span><span>117 sheep have 2 lambs each means 117x2=234 Lamps
</span>Plus
<span>All the other sheep have 1 lamb each means (191-19-117)=55
</span>Equal:
19x3+117x2+(191-19-117)=57+234+55=346 Lamps
Answer: 245 beads are plastic

Answer:
Range = 13
Mean = 8.4
Variance= 21.24
Standard deviation= 4.61
Step-by-step explanation:
2, 10, 15, 3, 13, 9, 14, 7, 2, 9
For the range
Let the set of data be arranged inn ascending order
Range= higehest value- lowest value
Range = 15-2
Range= 13
For the mean
Mean = (2+2+3+7+9+9+10+13+14+15)/10
Mean = 84/10
Mean = 8.4
For variance
Variance=((2-8.4)²+(2-8.4)²+(3-8.4)²+(7-8.4)²+(9-8.4)²+(9-8.4)²+(10-8.4)²+(13-8.4)²+(14-8.4)²+(15-8.4)²)/10
Variance= (40.96+40.96+29.16+1.96+0.36+0.36+2.56+21.16+31.36+43.56)/10
Variance= 212.4/10
Variance= 21.24
Standard deviation= √variance
Standard deviation= √21.24
Standard deviation= 4.609
Approximately = 4.61
Answer:
42/49 is the fraction
Step-by-step explanation:
you can't simplify so put the amount correct over the amount total.
