Answer:
Identifying at least one confounding variable that undermines the conclusion drawn in the fictional study is:
All students took the same comprehensive test.
Step-by-step explanation:
In a study, an independent variable causes an effect on the dependent variable. But a confounding variable is the variable that influences the independent variable as well as the dependent variable. If this third variable is not controlled, it might lead the researcher to make a wrong estimate of the relationship that exists between the independent variable and the dependent variable.
Answer:
The answer is (-2)
Step-by-step explanation:
<h3><u>Given</u>;</h3>
- a₁ = (-6)
- a₂ = (-4)
- and so on,
<h3><u>To</u><u> </u><u>Find</u>;</h3>
Here, we will use AP
Now, Common Difference (d)
d = a₂ – a₁ = (-4) – (-6) = (-4) + 6 = 2
Here, Common Difference (d) is 2
So,
a₃ = a₂ + d
a₃ = (-4) + 2
a₃ = -2
Thus, The missing number in this sequence is (-2).

I am assuming the equation would be something like 65 3/5 = 24 1/3 + d
Answer:
Value in $= 3x -600
Step-by-step explanation:
Let the value of the stock before investment= x
At the first year , the value tripled
Value after first year=3x
The second year , the stock reduces by $600.
So
The value of the stock after the second year
Value in $= 3x -600
Answer:
So, in order to solve this, you need to know slope. Slope is equal to rise (up/down) over run (left/right). The number at the end, which in this case is 2, is the y-intercept. So, first, graph a point on the y-axis, which is 2. Next, you can place any other point on the line, as long as it follows your slope, which is 3/5. If you need a better explanation, just graph (0, 2) on the y-axis and also graph the point (3, 5).
Have a good one,
