We sample because we want to get an overview of the population. It's usually impractical to study the entire population.
For example, say you want to know what percent of people who go to a certain grocery store have a dog. It wouldn't make sense to sample every single person who goes to that grocery store; there's just too many people. But if you took a sample of say, 100 people, and asked them if they had a dog, you could get a rough estimate of all the people.
Answer:
1/6
Step-by-step explanation:
To find the value of x that makes the equation true we isolate x on one side of the equation. Technically this is solving for x. The Division Property of Equality states that if we divide both sides of an equation by the same amount then we will have an equivalent equation. We can divide both sides of this equation by 36 to get x = 1/6
Answer:
When the actual expenses exceed the actual income, the result would be a negative dollar amount. (B)
Step-by-step explanation:
Let's let x equal the original price of the dress.
We know that 16.6666% is equal to 0.16666 in decimal form by dividing the percent by 100.
So we can set up the equation:
because we know the discount, and we know that the discount of the original price was subtracted from the original price.
So then let's simplify by taking out x, the common factor:
Then solve for x:
So now we know that the original price of the dress was $39.
Using iready the tutorial does not count as a grade and if your worried about passing the test turn your wifi off count to 10 then click the answer you think is right, if it is right turn wifi back on and click next, if wrong click next and it will kick you out of it then turn wifi back on and go back onto the lesson and repeat until you have the right answer, I always got 100% on my quizs this way
