K-means clustering is the process

a. estimating the value of a continuous outcome variable.
b. agglomerating observations into a series of nested groups based on a measure of similarity.
c. reducing the number of variables to consider in data-mining.
d. organizing observations into distinct groups based on a measure of similarity.

Option (b and d) are the correct answer for the above question.

Explanation:

K-means clustering is the concept of data mining, in which some observation is portioned on k groups of clusters. Clusters mean a group is made with the help of some similarities. This technique is used in data mining in which a user analyzes the data and gives the real outcomes which can be used for the future.

Options b and d also states that the observation is divided into some groups with the help of some similarities, that's why both are the correct option. while the other is not because--

some have built technology like spoofed call blockers into their networks, so there's nothing you would even have to install.

this happens because the number is known for scamming, they don't want it to me known as "scam likely." perhaps it's just a telemarketer. maybe it's an identity thief. it might even be a scam artist.  

either way, "scam likely" is probably not an old friend whose number you forgot that you saved. it's your wireless carrier's way of letting you know: answer at your own risk.

explanation:

to combat the seemingly rising epidemic of spam callers in the u.s., the nation's four major wireless carriers have been trying out new methods to reduce the number of unsolicited calls americans receive each day.

some have built technology like spoofed call blockers into their networks, so there's nothing you would even have to install.

hope this . mark me brainliest.
