Can you please insert a photo so I can help you
Answer:
38.5 pages
Step-by-step explanation:
11pages:2mins
x pages: 7 mins
you need to divide 7 by 2 and get 3.5, then multiply 3.5 by 11 and receive 38.5
The base number is 7, the exponent is 2, and I think the expanded form is 7x7
Nothing is mentioned...how am I supposed to help you?
Mean = (14 + 16 + 7 + 9 + 11 + 13 + 8 + 10) ÷ 8 = 11
Variance =
[ (14-11)²+(16-11)²+(7-11)²+(9-11)²+(11-11)²+(13-11)²+(8-11)²+(10-11)² ]/7 = 9.71
Answer: 9.71
