The graph below shows a scatter plot and the line of best fit relating the ages of children and the total number of times they have visited the doctor.Use the line of best fit to estimate the age of a child who has visited the doctor 40 times.

A. 14 years old
B. 13 years old
C. 12 years old
D. 11 years old

Answers

Answer:

The correct option is C.

Step-by-step explanation:

The graph below shows a scatter plot and the line of best fit relating the ages of children and the total number of times they have visited the doctor.

If a line passes through two points then the equation of line is

y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)

From the given graph it is clear that the line of best fit passes through the points (0,0) and (3,10). So, the equation of best fit line is

y-0=(10-0)/(3-0)(x-0)

y=(10)/(3)x           .... (1)

The equation of best fit line is y=(10)/(3)x. Where, x is age in year and y shows the total number of visits to the doctor.

We need to estimate the age of a child who has visited the doctor 40 times.

Substitute y=40 in equation (1), to find the value of x.

40=(10)/(3)x

Multiply both sides by 3.

120=10x

Divide both sides by 10.

12=x

The value of x is 12. It means the age of a child who has visited the doctor 40 times is 12.

Therefore the correct option is C.

The kid is around 12 years old that visits the doctor 40 times

Trisha drew a pair of line segments starting from a vertex.Which of these statements best compares the pair of line segments with the vertex?

The line segments and the vertex have length as a dimension of measurement and there are three collinear points on each.

Line segments and the vertex have two endpoints each and the distance between the end points is their dimension.

Line segments have two endpoints and a vertex is a common endpoint where two line segments meet.

The line segments and the vertex have their lines extending in one direction only and the lengths of both are

Answers

The right answer for the question that is being asked and shown above is that: "Line segments have two endpoints and a vertex is a common endpoint where two line segments meet." The fact that they started from a single point, then by default these two line segments have the same one endpoint.

Answer:

Line segments have two endpoints and a vertex is a common endpoint where two line segments meet.

Step-by-step explanation:

As both line have the same vertex, imagine both lines generating an angle between them, since they have a common vertex, this will also be the same end point that both segments share between them, they will only have other different endpoint and the space between those endpoints and the vertex would be the length of the segment.

Answers

i dont know what the question is but the answer is 1/5 of an hour

Rathan thinks all factors of even numbers are even. Which explains whether Rathan is correct? He is correct because the product of 2 and any number is even.
He is correct because the product of two even numbers is even.
He is incorrect because the product of an even number and an odd number is even.
He is incorrect because the product of two odd numbers is odd

Answers

The answer to this would be C, the third of the options. This is the only response that fully answers the question. For example, two factors of 42 would be 6 and 7, and both are not even, so given the absolute nature of Rathan's belief, there is no exception that can be made to make him correct. I hope this helps, and if it was sufficient to make you understand fully set it to the brainliest answer. Have a nice day! =)

The correct answer is:

He is incorrect because the product of an even number and an odd number is even.  

Explanation:

When you multiply any number by an even number, whether it is even or odd, the product will be even.

This means that an even number can have an odd factor, and Rathan is incorrect.
