The answer is 20 because
20.75x4.552= 94.454
And .5234x9.823= 5.1413582
Then when divided the answer is 18.37141011
But you have to round to the significant figure of 1 which in this case is to the tens place so 18 rounds up to 20

Answer: -1.33 .

Step-by-step explanation:

Formula to find the Z-score :

Z=\dfrac{\text{Expected value - Mean}}{\text{Standard deviation}}

Then , the z-score corresponding to the expected value of 163 will be :

Z=\dfrac{163-191}{21}\\\\=\dfrac{-28}{21}\approx-1.33

Hence, the z score corresponding to selling 163 inhalers is -1.33 .
