Answer:
(D) If the null hypothesis is true, there is a 24% probability of getting a sample difference in means as far or farther below 0 as the difference found in the samples.Explanation:
The answer is: " 2 − 6i " ; or, write as: " -6i + 2 " .

Explanation:
_____________________________________________
Given: <span>(x + yi) + 6i = 2 ; What is: (x + yi) ?
_____________________________________________
Subtract "6i" from EACH SIDE of the equation ;
_____________________________________________
x + yi + 6i </span>− 6i = 2 − 6i ;
_____________________________________________
to get: x + yi = 2 − 6i ; or, write as: -6i +2 .

Answer: 340m
Explanation:
Given that:
Streets are constructed from 10 m pieces;
A lamppost is placed at both ends and at every 10 m along its length ;
A lamppost is also placed at every notice board along its length :
Given that:
Einstein Street has 42 lamppost and 7 notice boards :
So,
7 lamppost for 7 notice boards :
Lamppost left = 42 - 7 = 35 lamppost
2 lamppost placed at both ends :
Lamppost left = 35 - 2 = 33 lamppost
Hence, the remaining is placed at 10 m along its length:
Hence, length of Einstein street :
33 lamppost each placed 10m from the starting lamppost = (33 * 10) = 330m
Distance between 33rd lamppost and the ending lamppost = 10m
Hence, total length = (330 + 10) = 340 m
A. i just read about this in my history book for school.
