Given that there is a survey of 100 randomly selected female members of the gym about choosing between "easy weight-lifting machines or the harder free weights".

Report of the survey says that "female members at the gym prefer the weight-lifting machines over the free weights."

Now we have to select from the given statements that correctly evaluate the report.

According to me "The question is biased towards a response of preferring to use weight-lifting machines." because description of word "hard" is used for "free weights" while word "easy" is used for "machines". That may persuade some people to choose the machine.

Since 100 females are randomly selected not specifically so "The sample is not biased."

Hence final answer should have two statements:

1) The question is biased towards a response of preferring to use weight-lifting machines.

2) The sample is not biased.

The pharmacist uses 67mg, 100g and 0.6 kg of drug to compound 3 separate precription. how much total drug did the pharmacist use

FromTheMoon [43]

Answer: 700.067 g

Step-by-step explanation:

Given : The pharmacist uses 67mg, 100g and 0.6 kg of drug to compound 3 separate prescription.

We know that 1 gram= 1000 milligram

and 1 kilogram = 1000 grams

Then, By UNITARY METHOD, $\text{1 mg}=\dfrac{1}{1000}\text{ gram}$

Now, We convert each amount of drug into grams as ,

$67\ mg=67\times\dfrac{1}{1000}\ g\\\\=0.067\text{ g}$

AND

$0.6\ kg=0.6\times100=60\text{ g}$

Now, the total drug used by Pharmacist (in grams) = $0.067+100+600=700.067\ g$

Hence, Pharmacist used 700.067 g of total drug.

Why is it important to solve an equation for a specific variable?

Svetllana [295]

It all depends on the importance of the variable its self. Its important to solve it so you know what the variable is and its important to solve one at a time because its impossible to solve a variable completely if you have two of them
