A health food store has launched a new pack of vitamins for children. The store records the number of packs ordered by a random sample of 100 online customers and the number of packs ordered by a random sample of 100 walk-in customers.

Two dot plots are shown one below the other. The title for the top dot plot is Online Customers and the title for the bottom plot is Walk-In Customers. Below the line for each dot plot is written Number of Packs. There are markings from 1 to 5 on each line at intervals of one. For the top line there are 0, 0, 1, 4, 5 dots respectively for marks from 1 to 5. For the bottom line there are 6, 2, 1, 0, 0 dots respectively for marks from 1 to 5

Which of the following inferences can be drawn about the buying pattern of the online customers versus that of the walk-in customers?

A. Online customers buy an average of four packs compared with walk-in customers, who buy an average of one pack.

B. Online customers buy an average of five packs compared with walk-in customers, who buy an average of two packs.

C. Online customers buy an average of four packs compared with walk-in customers, who buy an average of two packs.

D. Online customers buy an average of five packs compared with walk-in customers who, buy an average of one pack.

Answers

Answer: The inference to make using the median is: online customers by an average of five packs compared with walking customers who buy an average of two packs online.

Step-by-step explanation:

The inference based on the median is: online customers by an average of five packs compared with walking customers who buy an average of two packs online.

The median is the middle value, which has equal data points on the right and to the left.

The median for online customers is between 5 and 6.

The median for walk-in customers is 2.

Therefore, the inference to make using the median is: online customers by an average of five packs compared with walking customers who buy an average of two packs online.

The population of a city was 60,000 in 2015. In 2016, the population of the city was 63,000. The percent increase in the population from 2015 to 2016 was the same as it was from 2016 to 2017. What was the population of the city in 2017?

Answers

The answer of this question is 66,000.

The answers is 66,150.


When you do the formula to find the percent increase the higher amount minus the lower amount, divided by the old population is how you find the percent increase, thus there is a five percent increase. So 5 percent of 63000 is 63000 times .05 which is 3150 and 3150 plus 63000 is 66150

Answer:

the answer should be 4/8 hopefully because first of all you need to use a method that can help you save your life which is cross multiplying.

_1_= __?_

  2       8

you multiplied first 1 times 8 and then divide by 2 in which you will get an answer of 4/8 and to check it you divide 1/2 which gives you 0.5 and then divide 4/8 to see if it is an equivalent fraction and it will give you 0.5 in which yes sir its an equivalent fraction so 4/8 is the correct answer and have a great day.

Answer:

  1/2(n -10) = -4

Step-by-step explanation:

Understanding the given sentence as a math sentence requires that you first understand it as an English sentence.

Parsing the English

The subject of the English sentence is "difference". We know that a difference in math is two values separated by a minus sign. Having understood that, we need to identify the two values involved.

The descriptor of "difference" in the English sentence is "of a number n and 10." This tells us the two values are "n" and "10". The first one listed goes on the left of the minus sign. So, the difference we're talking about is ...

  (n -10)

The English sentence tells us that this difference is multiplied by 1/2. The math equivalent is shown as ...

  [tex]\dfrac{1}{2}(n-10)[/tex]

When the English tells us the result of this operation, it means this value is equal to that result. We are told this value is equal to -4

Writing the equation

We now know the left- and right-sides of the equation being described in English. That means the equation described is ...

   [tex]\dfrac{1}{2}(n-10)=-4[/tex]

Answers

Answer:

Because if a point is to be on the Y axis than it would have to not move on the x axis. Therefore the value of the X coordinate must be zero for a point to be on the Y axis. Please rate brainliest.

Answer: You will need 1080 in²

Step-by-step explanation:

The formula for finding the area of a triangle is:

Area = 1/2 x b x h

b = base length
h = height

So the equation would be:

1/2 x 12 x 30 = 180

After finding our answer of 180 we multiply it by the amount of pennants we want to hang in this case that number is 6

180 x 6 = 1080

That's how we arrive at our answer of 1080 in².
