Answer:
Systematic sampling.
Step-by-step explanation:
The systematic sampling is a type of random sampling in which a unit is selected from k units and after this every kth unit is selected until population is serially numbered from 1 to N arranged in a systematic way.
The statement shows that every 18th truck is selected until a sample of 60 trucks is selected. It shows that a systematic random sample is obtained with k=18 and thus, systematic sampling is used.

Answer:
4.3cm
Step-by-step explanation:
the radius of the hemisphere can be determined its volume
volume of a hemisphere = (2/3) x (n) x (r^3)
n = 22/7
r = radius
(2/3) x (22/7) x( r^3) = 165 cm^3
44/21 x r^3 = 165
divide both sides of the equation by 21/44
165 x 21/44
r^3 = 78.75
find the cube root
r = 4.2863 cm
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
the 100th terms, 8 is greater than 6, so add 1 to 2. this give 4.3cm
