Answer:
Step-by-step explanation:
|-3| means the absolute value of -3. The absolute value sign means the number without its negative. The dictionary says: the magnitude of a real number without regard to its sign.
So |-3|= 3 and -3= -3
Answer:
x = 1
Step-by-step explanation:
Using the rules of logarithms
log 
⇔ n log x
x = n ⇔ x = 
Given
3
(2x) = 3
(2x)³ = 3
(2x)³ = 2³
8x³ = 8 ( divide both sides by 8 )
x³ = 1 ( take the cube root of both sides )
x = 1
The first statement is correct.
If at the end of the study, the sociologist had a sample of 500 expectant parents and he estimates that there are 6 million expectant parents in the United States then the value of n is 500.
Given that the sample size is 500 and the number of expectant parents be 6 million.
We are required to find what n represents and value of n.
The value of n is 500. Small n shows the sample size and capital N shows the size of population.
Sample is that part of the population that represents the characteristics of the whole population.
Population is the number of individuals present in the area which a researcher wants to observe.
Hence if at the end of the study, the sociologist had a sample of 500 expectant parents and he estimates that there are 6 million expectant parents in the United States then the value of n is 500.
