Step-by-step explanation:
Answer: 60
Step-by-step explanation:
mean: you just add all 15 numbers then divide the number you get by 15.
55+57+57+58+59+59+59+59+59+61+62+62+63+64+66=900
900/15=60
The answer to this is 10 markers
80% = .8
8/.8 = 10
8/10 = .8
X^2+8x+15
= x^2 + 5x + 3x + 15
= x(x+5) + 3(x+5)
= (x+5)(x+3)
Since I am guessing that you mean One Fifth of the way filled my answer is 10.8 because when you divide 13.5 by five you get 2.7. And since one fifth is already filled, you just have to multiply it by four.
