Answer:
If there are 6 tiles, the probability is 1/6
Step-by-step explanation:
we know that
the equation
describe a vertical parabola with vertex at point 
if 
-------> the parabola open Up and the vertex is a minimum
if 
-------> the parabola open Down and the vertex is a maximum
in this problem we have
---> because is positive (given problem)
so
The vertex is a minimum
therefore
<u>the answer is the option C</u>
Up
4x - 3y = 8 ⇒ 8x - 6y = 16
5x - 2y = -11 ⇒ 15x - 6y = -33
-7x = 49
-7 -7
x = -7
4x - 3y = 8
4(-7) - 3y = 8
-28 - 3y = 8
+ 28 + 28
-3y = 36
-3 -3
y = -12
(x, y) = (-7, -12)
To use elimination you have to multiply the first graph by 2 and the second graph by 3 so that the two y-axis can be equal to -6. Then you do the rest to find the answer of the x-axis and the y-axis.
Answer:
1. This is an observational study.
2. The explanatory variable is A. red meat consumption
3. The response variable is B. Whether or not a subject dies.
Step-by-step explanation:
1. An observational study is a type of study where the researcher would observe the effects and he would also make no attempt to change the outcome
2. The explanatory variable is also called the independent variable and in this case it is red meat consumption because it is what would be used to predict the dependent variable
3. The response variable is known as the dependent variable it is our variable of interest. It is what the researcher is trying to find out. In this case the answer is whether or not the subject dies
