Answer 1

Answer:

Answer:

Options B,C and E are correct choices.

Step-by-step explanation:

We are asked to find correct answers for the given box and whisker plots.

Let us our options one by one.

A. This option is false as lowest value for children's cereals is 30 and highest value for adults is 35.

B. This option is correct. We can see our upper value for combined range will be 60 and lower value will be 5 and range is upper value- lower value.

$60-5=55$

C. Since we know that we can find spread of data by its range.

$\text{Range for children's cereals}=60-30=30$

$\text{Range for adult's cereals}=60-30=30$

So option C is correct indeed.

D. This options is false because for adults mean and median are different while for children mean and median are same.

E. We can see that median for children's cereals is 45 and it is about 12 for adults.

We can see that $12*3<45$ . So median amount of sugar in children's cereals is 3 times as much as the median amount of sugar in adult's cereals.

Therefore, options B,C and E are correct choices.

Noah is studying dogs to determine their interest in blue toys versus red toys. He splits a group of 20 dogs into 2 groups. One group is given blue toys and the other is given red toys. Noah has the dogs play with the toys until they lose interest. He finds that the dogs that had blue toys played with them 2 minutes longer than the dogs that played with red toys. Noah rerandomizes the data, calculates the difference between the means, and creates the dot plot shown below. Based on the data, can Noah conclude the difference is significant?.

Answers

Noah re randomizes the data, calculates the difference between the means, and creates the dot plot shown below. Based on the data, can Noah conclude the difference is significant?

Answer: by looking at the graph we can make the conclusion that Yes, Noah can conclude the difference is significant because a 2-minute difference is not likely to happen by chance. Please see the graph in the attachments.

I hope it helps, Regards.

What is the difference?

The difference is a key concept of philosophy, denoting the process or set of properties by which one entity is distinguished from another within a relational field or a given conceptual system.

By looking at the graph we can make the conclusion that Yes, Noah can conclude the difference is significant because a 2-minute difference is not likely to happen by chance. Please see the graph in the attachments.

Atraeus is solving the quadratic equation by completing the square.7x^2 – 14x + 6 = 0 7x2 – 14x = –6 A(x^2 – 2x) = –6What is the value of A?

Answers

so we first minus 6 both sides
7x^2-14x=-6
then we have
A(x^2-2x)=-6
what is A?

hmm (this should be painfully obvous, but if not, here are steps)

7x^2-14x=-6
A(x^2-2x)=-6

7x^2-14x=-6=A(x^2-2x)
7x^2-14x=A(x^2-2x)
undistribute 7
7(x^2-2x)=A(x^2-2x)
divide both sides by (x^2-2x)
7=A

A=7
