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.

Answer:

The length of a pencil is 4.5 inches. The length of a crayon is 2.1 inches.

Step-by-step explanation:

Let pencils be p

Let crayons be c

6 pencils and 5 crayons are 37.5 inches. This will be:

6p + 5c = 37.5 ........ equation 1

7 pencils and 6 crayons are 44.1 inches. This will be:

7p + 6c = 44.1 ........ equation 2

Multiply equation 1 by 7

Multiply equation 2 by 6

42p + 35c = 262.5 (3)

42p + 36c = 264.6 (4)

Subtract 4 from 3

c = 2.1

Plug the value of c into equation 1

From equation 1

6p + 5c = 37.5

6p + 5(2.1) = 37.5

6p + 10.5 = 37.5

6p = 37.5- 10.5

6p = 27

p = 27/6

p = 4.5

Dilated ∆ ABC about point C with a scale factor of 2

Translate ∆ A' B' C' to the 0.5 by 2 units.

Determining the scale factors of a triangle

From the triangles given, ∆ DEF was dilated to ∆ ABC

The dilated triangle is = ∆ ABC

To find the scale factor uses for the dilation of the triangle, the length of the triangle AC and DF are considered.

AC from the scale= -2 -(-7)

= 7-2= 5

DF= 9-6.5

= 2.5

Therefore the scale factor = 5/2.5 = 2

And since the scale factor of dilation is 2 this means that ∆ A' B' C' can be translated to the 0.5 by 2 units.

How to write fractions in simplest form?
( I give brainliest )

Answers

It's pretty easy, take the example of this fraction... [tex]\frac{2}{4}[/tex]

What you do in here is that you note down the factors of 2 and 4 over here.

Factors of 2 and 4:

2 = 1, 2

4 = 1, 2, 4

Now, you see that the GREATEST Common Factor (GCF) over here is 2.

Now that we see the GCF of 2 and 4 is 2, what you do next is, you have to divide 2 by 2 AND 4. When you do this, you will get your results. 2 = 1 and 4 = 2, now put this in the fraction form again, meaning switch 2 with 1, and 4 with 2 in the fractions... [tex]\frac{1}{2}[/tex]

So your simplified fraction is [tex]\frac{1}2}[/tex]!

Answer:

A fraction is in simplest form when the top and bottom cannot be any smaller, while still being whole numbers.

You can simplify a fraction by dividing the top and bottom by the greatest number that will divide both numbers exactly. They must stay whole numbers.

Answer:

There are 2 ways you could do this. The easy way is the first one.

1. Divide 40 by 5 and you get 8. 2. After you get that answer, then you have to multiply 8x8=64. So she gets $64 per hour.

Then there is the harder one. This is if they say to show your work.

Answers

Answer:

probability=number of favorable outcome÷total number of favorable outcome

Step-by-step explanation:

A the probability that all children are boys =3÷3 =1

same answer with the girl children

Answer:

A) 1/8 or 0.125 for three girls and three boys

B) 3/8 or 0.375 for two girls and one boy

C) 3/8 or 0.375 for two boys and one girl

D) 1/2 or 0.50, explanation provided below

Step-by-step explanation:

Part A) If a family has three children, the probability that all three children are girls can be found by first finding the probability of one child being a girl. The probability of being a girl in this case is 1/2. The probability of three girls is thus (1/2) * (1/2) * (1/2) = 1/8 or 0.125. The probability of one child being a boy is 1/2, and so rather than repeating the above steps, we can simply say that it is also 1/8 or 0.125.

Part B) For this part, it is probably easiest to list the combinations:

BBB

BBG

BGB

BGG

GBB

GBG

GGB

GGG

There are three outcomes with two girls and one boy and thus the probability is 3/8.

Part C) Looking at the combinations above, we also see that there are three outcomes with two boys and one girl, and thus the probability is 3/8.

Part D) The fact that Josh has a younger brother does not affect the probability that the third child will be a girl or boy. The probability of the third child being a boy is still 1/2.
