243
Step-by-step explanation:
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:
+9-12
==3
Step-by-step explanation:
when u multiply - and + it will always be -
A vertical stretching<span> is the </span>stretching<span> of the graph away from the x-axis.
It means you simply need to multiply the scale factor with the x-values.
</span>If point H is located at <span>(-2, 0),and the scale factor is 2,then the stretch would be (-2*2.5,0)
Hence,the new point will be:
A.(-5,0).
</span>
14)NO..... -2x+5y=10.....-2(-3)+5(2)=10.....6+10 is not =10
15)YES......-2x+5y=10....-2(-10)+5(-2)=10.....20-10=10
16)YES......-2x+5y=10.....-2(5)+5(4)=10......-10+20=10
