Answer:

C) independent variable = age

dependent variable = reaction time in milliseconds

Step-by-step explanation:

The linear regression statistical test is best used for research experiment where there is a single dependent and one independent variable whjre both variables are numeric. In the given options above, the city of residence, gender, college major and political affiliation are all possible categorical variables and age, salary, miles driven and reaction time are all numerical variables. Hence, the best situation in which to use linear regression is a test where both the independent and dependent variables are either age, salary, reaction time or miles driven.

Find the equation for the<br> following parabola<br> Vertex (-2,-4)<br> Focus (-4,-4)

iren [92.7K]

Answer:

None of the given option corresponds to the answer.

Step-by-step explanation:

The parabola has its axis of symmetry parallel to the x-axis and is represented by the following expression:

$x - h = 4\cdot p \cdot (y-k)^{2}$

Where:

$h$ , $k$ - Components of the vertex location, dimensionless.

$p$ - Absolute distance of focus with respect to vertex, dimensionless.

The absolute distance is determined by following formula:

$p = x_{F}-h$

Where $x_{F}$ is the horizontal component of focus with respect to origin.

If $h = -2$ , $k = -4$ and $x_{F} = -4$ , the absolute distance and the equation that represents the parabola is:

$p = -4+2$

$p = -2$

$x +2 = -8\cdot (y+4)^{2}$

None of the given option corresponds to the answer.

If you picked 41.5% of the apples on a tree, and you picked 34 apples, how many apples did the tree contain before you starting

german

Around 81 whole apples
34 divided by 41.5 = 0.81927711
0.81927711 x 100 = 81.9.....
So that rounded 81 whole apples and 0.9.... of an apple

It’s 81 apples
