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.

Simplify the expression below. (2n/6n+4)(3n+2/3n-2)

andrezito [222]

Answer:

$\frac{n}{3n-2}$

Step-by-step explanation:

Given the expression:

$\frac{2n}{(6n+4)} \cdot \frac{3n+2}{3n-2}$

Using the distributive property: $a \cdot (b+c) =a\cdot b+a\cdot c$

$\frac{2n}{2(3n+2)} \cdot \frac{3n+2}{3n-2}$

Simplify:

$\frac{2n}{2} \cdot \frac{1}{3n-2}$

Simplify:

$\frac{n}{3n-2}$

Therefore, the simplified given expression is, $\frac{n}{3n-2}$

Nataliya [291]

Answer:

a) $P($

b) $n=(HHH, HHT, HTH, HTT, THH, THT, TTH, TTT).$

Step-by-step explanation:

From the question we are told that:

3 coin are tossed

Therefore

Sample space $n=(HHH, HHT, HTH, HTT, THH, THT, TTH, TTT).$

Generally the sets that correspond with the result of at most one tail is therefore given as follows

$P($

Therefore

The result is at most one tail when

what proteins embedded in the phospholipid bilayer do what in the cell membrane? A) organize amino acids for protein synthesis B

ohaa [14]

Answer: The answer is (D) prevent the passge of certian molecules into the cell.

Step-by-step explanation: We have four option out of which one describes the functions of protein present in the phospholipid bilayer in the cell membrane.

Phospholipid bilayers are critical components of cell membranes. Its function is to act as a barrier to the passage of molecules and ions into and out of the cell. It allows selective substances and molecules to come in and go out of the membrane.

Thus, the correct option is (D).
