4/5 = 1/5 + 3/5 is the only answer that I can think of. It's asking for the cumulative property of addition and that's all the information they give you
Answer:
f(1) = 1
Step-by-step explanation:
The value of f(1) simply means what is the corresponding output we would get for an input of 1.
This also implies that for what of y is x equal to 1?
From the graph, when x = 1, y = 1.
Thus:
f(1) = 1
Let x be the angle. The complement is 3x + 10. The sum of two complementary angles is 90. So,
x + 3x + 10 = 90
4x + 10 = 90
4x = 80
x = 20
Plug x into the complement
3(20) + 10 = 70
The angle is 20 degrees and the complement is 70 degrees

Hence,
Answer:
Sample: few thousand adults
Population: all the adults
Step-by-step explanation:
A sample is a subset of the population, selected randomly.
In this case:
The sample consist of the few thousand adults selected to determine the opinions about the National polls.
The population consist of all the adults belonging to the said nation.
Consider an example about the new President election.
To determine which of the two candidates (say <em>A</em> and <em>B</em>) has a higher probability of winning the President election, the election society took a random sample of voters and asked who they think will be a better president.
The sample selected will be large enough, probably 10% of the population of all voters.
From this study it can be estimated which candidate has the higher chance of winning.
