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 graph of a function f is the set of points which satisfy the equation y = f(x). ... However, of these two answers, only x = −2 fits in the domain.
Step-by-step explanation:
Answer:
n = 10
Step-by-step explanation:
n is the altitude of the right triangle.
Apply the right triangle altitude theorem/geometric mean theorem to find n.
Which is:
h = √(xy)
Where,
h = n =?
x = 5
y = 20
Plug in the value into the equation
n = √(20*5)
n = √100
n = 10
100-35=65
seems to be
x times 0.65=36.48
if original price is x, then the a discount of 35% equals 36.48
A air of boots is on sale for 35% off. The original price of the boots is x, $56.12 is x or the original price
3rd option is correct
(5x-18)+(4x+7)=180
5x+4x=180+18-7
9x=191
x=191/9
Answer: x=191/9
