8 hours because 11/3 of an hour is 3 hours and 40 minutes. 12/9 is 4 hours. 1/3 is 20 minutes and if you add it all together you get 8 hours
Answer:
Angle Q
Step-by-step explanation:
As I said on my previous posts, all you need to remember is CPCTC (corresponding parts of congruent triangles are congruent)
Q corresponds to B, and is thus congruent
Answer: A) 23.5%
Explanation: 340-260= 80
80/340=0.2352x100=23.5

Answer:
3.83
Step-by-step explanation:
Mean of x = Σx / n
Mean of x = (14 + 19 + 13 + 6 + 9) / 5 = 12.2
Sum of square (SS) :
(14-12.2)^2 + (19-12.2)^2 + (13-12.2)^2 + (6-12.2)^2 + (9-12.2)^2 = 98.8
Mean of y = Σy / n
Mean of y = (101 + 89 + 48 + 21 + 47) / 5 = 61.2
Σ(y - ybar)² = (101-61.2)^2 + (89-61.2)^2 + (48-61.2)^2 + (21-61.2)^2 + (47-61.2)^2 = 4348.8
df = n - 2 = 5 - 2 = 3
Σ(y - ybar)² / df = 4348.8 / 3 = 1449.6
√(Σ(y - ybar)² / df) = √1449.6 = 38.074
Standard Error = √(Σ(y - ybar)² / df) / √SS
Standard Error = 38.074 / √98.8
Standard Error = 3.83
