Answer:
Step-by-step explanation:
The rocket accelerates by burning the fuel it carries and ejecting the burned ... As a result, it permitted multiple launches as opposed to single-use rockets. ... we can use Newton's second law to calculate the consequent acceleration. ... (a) A 5.00-kg squid initially at rest ejects 0.250 kg of fluid with a velocity of 10.0 m/s.

Answer:
A) allows the population effect on log earnings of being married to depend on gender
Step-by-step explanation:
The regression equation of a dependent variable based on two or more independent variables is of the form:
![Y=b_{0}+b_{1}X_{1} +b_{2}X_{2}+b_{3}X_{1}X_{2}](https://tex.z-dn.net/?f=Y%3Db_%7B0%7D%2Bb_%7B1%7DX_%7B1%7D%20%2Bb_%7B2%7DX_%7B2%7D%2Bb_%7B3%7DX_%7B1%7DX_%7B2%7D)
Here,
<em>Y</em> = dependent variable
and
= independent variables
= interaction term
= regression coefficients.
If there is a significant interaction effect present then this implies that the effect of one independent variable (
or
) on the dependent variable (<em>Y</em>) differs every time with different value of the other independent variable (
or
) .
The provided regression equation is:
![Y_{i}=\beta _{0}+\beta _{1}D_{1i}+\beta_{2}D_{2i}+\beta _{3}D_{1i}D_{2i}+u_{i}](https://tex.z-dn.net/?f=Y_%7Bi%7D%3D%5Cbeta%20_%7B0%7D%2B%5Cbeta%20_%7B1%7DD_%7B1i%7D%2B%5Cbeta_%7B2%7DD_%7B2i%7D%2B%5Cbeta%20_%7B3%7DD_%7B1i%7DD_%7B2i%7D%2Bu_%7Bi%7D)
= dependent variable
and
= independent variables
In this case the interaction term is defined as follows:
The effect of being married on log earnings is dependent on different values of the variables
, i.e. the gender of the
person.
Thus, the correct option is (A).
