13.9%
Step-by-step explanation:
Given data
Expected weight = 230 pounds
Actual weight= 262 pounds
Required
The percent error
Error= Actaul- expected/ expected *100
Error= 262-230/230*100
Error=32/230*100
Error=0.139*100
Error=13.9%
Hence the error is 13.9%
Answer:
13, 14, 15
Step-by-step explanation:
Let x = age of one of the siblings
Since the age of the siblings are consecutive integers, the age of the next sibling would be x + 1 and the age of the third sibling would be x + 2
x +( x +1) + (x +2) = 42
3x + 3 = 42
collect like terms and solve for x
x = 13
The age of the first sibling is 13
The age of the second sibling is x + 1 = 13 + 1 = 14
The age of the third sibling is x + 2 = 13 + 2 = 15
