Answer:
Standard error for the proportion of social media users who are concerned about privacy
S.E = 0.0219
Step-by-step explanation:
<u><em>Explanation:</em></u>-
Given data recent survey of 500 social media users, 300 stated that they were concerned about privacy
<em>Size of random sample 'n' = 500</em>
<em> x = 300</em>
<em>sample proportion </em>
<em></em>
Standard error for the proportion of social media users who are concerned about privacy is determined by
<em></em>

I believe 4/13 is the bigger number because 0.36>0.3
I suggest using a calculator to check but I believe 3/10 is the rational number because it terminates and doesn't repeat
Systematic Random Sample, Stratified Random Sample, and Simple Random Sample.
This answer is 467 because if u divide 11,208 by 24 it equals 467
Answer:
(a-1) *(a^2 +a-1) (a+2)
Step-by-step explanation:
a^4+2a^3-a-2
Lets factor by grouping
a^4-a + 2a^3-2
Factor out an a from the first group and a 2 from the second group
a(a^3 -1) +2(a^3-1)
Factor out (a^3-1)
(a^3-1)(a+2)
We need to recognize that a^3-1 is the difference of cubes
(x^3-y^3) = (x-y) (x^2+xy+y^2)
Let x=a and y=1
(a-1) *(a^2 +a-1) (a+2)
