Answer:
The solution to this question can be defined as follows:
Step-by-step explanation:
In choice a:
Both children between 5 and 15 years old and 160 years old are also the populations of interest, and Kids from 5 to 15 years of age.
In choice b:
These findings could be compared like we do not know whether the groups were randomly selected, and the allocation is still not random; there could be no casual conclusion because the statement is valid even With sample research, and after randomization, filtering, and testing of 160 specimens (instruction vs no-instruction) Its analysis can be common to the community and replicated. There could be explanatory relations generated by experimental research. This analysis is observational and can therefore be used Causal relationships are established.gggg
Answer: 6x + 15
Step-by-step explanation: The distributive property tells us that if we are given an expression such as 3(2x + 5), we can multiply the 3 by both the 2x and the 5 to get 6x + 15.

Answer:
It is therefore a exponential function, as y increases with x.
Step-by-step explanation:
coordinates: ( 7 , 5 ) , ( 16 , 10 )
Slope: 
: 
: 
equation: y - y1 = m( x - x1 )
: 
: 
check if third coordinates matches:
......does not match, so its not linear.
