Use the information given to find a convenient class width. Then list the class boundaries that can be used to create a relative

notka56 [123]

Answer:

hello some information is missing below is the missing information

8 classes for n = 75 measurements; minimum value = 20; maximum value = 175

answer : width = 20

class boundary : 20,40,60,80,100,120,140,160,180

Step-by-step explanation:

Using the information given the convenient class width

= (maximum value - minimum value) / number of class

= ( 175 - 20 ) / 8

= 155 / 8 = 19.375 to the nearest multiple of 5 = 20

Using the minimum value as the smallest class boundary

the class boundary will be :

20,40,60,80,100,120,140,160,180

since the maximum value 175

A pharmacist added 50 g of drug to make a total of 200 mL of solution. What is the percentage of drug in the resultant solution?

Answer:

The percentage of drug in the resultant solution is 25% .

Step-by-step explanation:

Given :A pharmacist added 50 g of drug to make a total of 200 mL of solution.

To Find : What is the percentage of drug in the resultant solution?

Solution:

Amount of drug = 50 g

Amount of solution = 200 ml

So, the percentage of drug in the resultant solution = $\frac{\text{Amount of drug}}{\text{Amount of solution}} \times 100$

= $\frac{50}{200} \times 100$

= $25\%$

Hence The percentage of drug in the resultant solution is 25% .
