Answer: first option
Step-by-step explanation:
Direct variation equation has the following form:

Where "k" is the constant of variation.
In direct variation when the variable "x" increases, the variable "y" increases by the same factor and when the variable "x" decreases, the variable "y" decreases by the same factor.
Inverse variation equation has the form:

Where "k" is the constant of variation.
In inverse variation when the variable "x" increases, the variable "y" decreases by the same factor and when and when the variable "x" decreases, the variable "y" increases by the same factor.
Given the equation:

You can observe that "r" varies directly with "l" and inversely with "p" and "t"
Answer: Option #1
Step-by-step explanation:
99 % confidence level - so it has to be 2.58 not 2.33 ( thats 98% confidence level )
then 12times facing u out of 45 times .... 12/45= .27
Option #1 : 0.27 +/- 2.58 StartRoot StartFraction 0.27 (1 minus 0.27) Over 45 EndFraction EndRoot
Answer:
We know that the prize of 6 bags of marbles is $18.
Then if each one of the bags costs C, the 6 bags will cost a total of 6 times C.
Then the cost is:
6*C
and this is equal to $18
6*C = $18
Now we want to solve this for C, remember that we can divide both sides of the equation by the same number, then let's divide both sides by 6:
6*C/6 = $18/6
C = $18/6 = $3
Each bag costs $3.
Below you can see a double number line, where above is the number of bags and below is the prize:
The answer is 1.74 kpm because you just divide distance by time
