The first thing we must do for this case is to define variables:
x: the total mass of the chemical in the container
y: a sample of a chemical from a container
We have the following equation:
y = (3/10) x - 5 3/4
Then, for y = 39.1 we have:
39.1 = (3/10) x - 5 3/4
Clearing x:
(3/10) x = 39.1 + 5 3/4
(3/10) x = 44.85
x = (10/3) * (44.85)
x = 149.5 grams
Answer:
the total mass in grams of the chemical in the container before the scientist removed the sample of 39.1 grams was:
x = 149.5 grams.
The

row is filled by just plugging in the corresponding values of

and

into the ODE.
For example, when

and

, you have

and so on.
Answer:
The width is 3 yds
Step-by-step explanation:
Area = length * width
18 = 6*w
Divide each side by 6
18/6 = 6w/6
3=w
The width is 3 yds
Answer:
5740
Step-by-step explanation:
Answer:
The 132 who responded is the SAMPLE.
Step-by-step explanation:
In a survey about a new immigration law in Georgia, "46% of the 132 Georgia farmers, agricultural processors, and farm service businesses who responded said they were experiencing some degree of labor shortage"
So, here the 132 who responded are samples.
Sample is defined as a small part of a surveyed population, that shows what the whole population must be like.
