Accuracy refers to how closely the measured value of a quantity corresponds to its "true" value.
precision expresses the degree of reproducibility or agreement between repeated measurements.
the more measurements you make and the better the precision, the smaller the error will be.

The point is to stablish the difference between accuracy and precision.

- Accuracy measures the proximity to the true value being measured.

- Precision refers to how close measurements of the same quantity are to each other, even if they are not close to the true value.

Step-by-step explanation:

When the values are not close to the true value, the measurements are not accurate, and if several measurements are not very close to each other, then they are not very precise either.

When the measurements are all close to the true value, they are accurate, and if the measurements are all close to each other, they are precise.

When all of the measurements are close together, they are precise, but if they are not close to the true value, they are not accurate.

When all of the measurements are close together, they are precise, but if they are not close to the true value, they are not accurate.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
