Answer:
Hallmark is using the Age segmenting dimension.
Explanation:
Most businesses and organizations tend to understand their customers, that is, their behaviors on purchases.
There are 7 important ways businesses segment their customers. They are:
- Income
- Age
- Gender
- Acquisition Path
- First purchase
- Geography
- Device type
In our scenario, Hallmark is using the Age segmenting dimension because they can identify that its a teenage girl that is sending theme card to her boyfriend's cell phone.
Answer:
The correct Answer is 0.0571
Explanation:
53% of U.S. households have a PCs.
So, P(Having personal computer) = p = 0.53
Sample size(n) = 250
np(1-p) = 250 * 0.53 * (1 - 0.53) = 62.275 > 10
So, we can just estimate binomial distribution to normal distribution
Mean of proportion(p) = 0.53
Standard error of proportion(SE) = 
= 
= 0.0316
For x = 120, sample proportion(p) = 
= 
= 0.48
So, likelihood that fewer than 120 have a PC
= P(x < 120)
= P( p^ < 0.48 )
= P(z < 
) (z=
)
= P(z < -1.58)
= 0.0571 ( From normal table )
Answer:
What is Robotics?
Robotics is the branch of technology that deal with the design, construction, operation and application of robots as well as computer system for there control, sensory feed back, and information processing. the design of given robotic system often contain principle of mechanical or electronic engineering and computer science. The word robotic was first used in 1941 by the writer Isaac Asimov.
Branches of robotics:
Artificial intelligence: The developing of an intelligence of machine and is a branch of computer science.
Nano Robotics : the field of creating machines that are at a scale of a nano meter.
Tele-presence: The study given to an illusion of being at a place without being there physically.
Robot Locomotion: The study of method that Robots used to transport them selves from place to another.
Robots have long captured the human imagination but despite many advances robots have yet to reach the potential so often envisioned in science fiction today engineers and computer scientist are still pursuing one missing ingredient high intelligence it would be nice for example: if robots possessed the intelligent needed to cope with uncertainty, learn from experience and work as team.
Intelligent robots will be one of the engineering achievement of 21 century said Junku Yuh, how leads the robotics program in the national science foundation computers and information science and engineering directorate "we will see them more and more in our daily life".
Answer:
//here is code in java.
import java.util.*;
class Solution
{
// main method of class
public static void main (String[] args) throws java.lang.Exception
{
try{
// declare an initialize first string variables
String st1="hello";
// declare an initialize first string variables
String st2="world";
// create another string variable
String st3;
// exchange the value of both string variables
st3=st1;
st1=st2;
st2=st3;
System.out.println("value of first String after exchange: "+st1);
System.out.println("value of second String after exchange: "+st2);
}catch(Exception ex){
return;}
}
}
Explanation:
declare and initialize two string variables.Create another string variable "st3". first assign value of "st1" to "st3" after then value of "st2" to "st1" and then assign value of "st3" to "st2". This will exchange the values of both the string.
Output:
value of first String after exchange: world
value of second String after exchange: hello
