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.
Answer:
1.The sum of thrice a certain number and six is greater than twenty seven.
2. Three times a certain number added to six the result is greater than twenty seven.
Step-by-step explanation:
The inequality whose word problem to be written is 3x + 6 > 27
Let x be a certain number.
So, we can write the following as the word problem of the inequality :
1.The sum of thrice a certain number and six is greater than twenty seven.
2. Three times a certain number added to six the result is greater than twenty seven.
Answer:
x=< -1
Step-by-step explanation:
move the constant to the right-hand side and change its sign. 2x<-5+3
Calculate the sum
2x<-2
Divide both sides of the inequality by 2
x <-1
We need to calculate the other triangle side.
Using the Pythagorean Theorem,
3rd side^2 = 360^2 -160^2
