Answer is B) control group
Step-by-step explanation:
Survey is when you ask questions to a group of people. Has nothing to do in this case. Correlational does not exist but correlation means the association between two groups.
In an experiment, you apply a treatment, or a conditions that differentiates groups and measure an outcome . In this case the treatment is drinking alcohol to measure memory. The group that receives the treatment is the experimental group and the one that not receives the treatment is the control because, we are comparing or controlling alcohol consumption in this group to measure differences in memory with the experimental group.
Answer:
The axis of symmetry is the line that divides the parabola into 2 congurent halves. The vertex is the highest or lowest point of the quadratic.
Hi there!
In order to solve this equation, we need to multiply:
17.8 * 100,000 = 1,780,000 cm
Since 100000 cm = 1 km, 17.8 km = 1,780,000 cm
Hope this helps!

Answer to solving for y: <em> y = -2.</em>
<em />
Answer for simplifying the expression: -12y - 4.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We are given that x = -4y and that the equation is 3x + 2y = 20.
<em>We need to evaluate.</em>
<em />
3x + 2y = 20
||
\/
3(-4y) + 2y = 20.
<em>To solve for y, y = -2.</em>
||
\/
3(-4y) + 2(-2) = -12y - 4.
