Answer:

12 and 15 or

12 and 18 or

15 or 18

Step-by-step explanation:

The two numbers have to both be divisible by 3, since their greatest common factor is 3. This only leaves..

12, 15, or 18 (no other numbers between 10 and 20 are divisible by 3)

The factors of 12 are: 2, 3, 4, 6, and 12

The factors of 15 are: 3, 5, and 15

The factors of 18 are: 2, 3, 6, 9, and 18

All three numbers have 3 as a greatest common factor, so we have 3 pairs of numbers they could be...

12 and 15 or

12 and 18 or

15 or 18

Suppose a population consists of 50,000 people. Which of the following

vampirchik [111]

Answer:

The number that would represent a sample statistic of a population but not a parameter is:

O A. Neither 500 nor 50,000

Step-by-step explanation:

The reason behind this is that a parameter has to follow a certain guideline because it needs to fulfill a rule to be considered one. There has to be a correlation, so if we have no clear establishment the number can't be a parameter. Thus, 500 would be the minimum 1% to be considered as a parameter and 50,000 the whole universe of the population. They keep a correlation, therefore any number but they would be a sample statistic.

Find the equation of the line that passes through points (4,5) and (-1,6).

steposvetlana [31]

First find the slope using the formula $m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$
Substitute the values in:
$m= \frac{6-5}{-1-4}= -\frac{1}{5}$
Point-slope form is $y=m(x-x_{1})+y_{1}$
Substitute (it doesn't matter which point you choose; I chose (4,5):
$y=- \frac{1}{5} (x-4)+5=-\frac{1}{5}x+\frac{29}{5}$
Therefore, the answer is D. $y=-\frac{1}{5}x+\frac{29}{5}$
