Answer:
C:12
Step-by-step explanation:
should be 13.5
The first quartile (Q1) is defined as the middle number between the smallest number and the median of the data set.
so the middle number of 10,11,12,15,17,19 is 13.5 since 12+15=27/2=13.5
the closest answer choice is C! Hope this helped!
Given :
New York City has a population of 8.55 million and 300 square mile area .
Manhattan has 1.64 million and 23 square miles area .
To Find :
How much greater is the population density of Manhattan than New York City.
Solution :
Population density of New York City :
Now ,
Therefore , population density of Manhattan is greater than New York City .
Hence , this is the required solution .
That trinomial can't be factored. You would have to complete the square to factor it and even then your answer would be an imaginary number.
x² + x + 12 = 0
x² + x = - 12
x² + x + 1/4 = - 12 + 1/4
x² + x + 1/4 = - 11 3/4
x² + x + 1/4 = - 47/4
(x + 1/2)² = - 47/4
x + 1/2 = +/- √(- 47/4)
x + 1/2 = +/-
x = 1/2 +/-
If the constant was a negative, it would be factor-able (is that a word?).
Answer:
-∞ < x < ∞
Explanation:
x³ is the inverse of ∛x and x³ has range of all real numbers and is one to one function, so its inverse will have domain of all real numbers.
