Answer:
Method A.
Step-by-step explanation:
For solving this question we need to find out the z-scores for both methods,
Since, the z-score formula is,
Where, is mean,
is standard deviation,
Given,
For method A,
Thus, the z score for 34 is,
While, for method B,
Thus, the z score for 34 is,
,
Since,
Hence, method A is preferred if the procedure must be completed within 34 minutes.
You can't factor out c or d since we don't know what they are so you have to find an integer. both are divisible by 5, which would become 5(9c+2d). 9 and 2 don't have anything in common so that is it.
45c+10d = 5(9c+2d)
Answer:
15 years
Step-by-step explanation:
Let e represent Edith's age. Then e also represents her brother's age.
Then:
e = 5e - 60.
Consolidating the e terms, we get 60 = 4e. Thus, e = 15.
Edith is 15 years old. So is her brother.
