Answer:
5b-5
Step-by-step explanation:
When doing these kinds of problems you want to do dributive property which means you multiply whatever number is outside of the (), which is 5, and multiply that by b and 1.
when numbers are outside the () and right next to them without anything like +,-, or a division sign, it means to multiply.
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:
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:
= 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).
Answer:
one to one function
Step-by-step explanation:
f(x)=6x+1 can only be a one to one function when x1=x2
Now,
f(x1)=f(x2)
or, 6x1 + 1 = 6x2 + 1
or, 6x1 = 6x2
or, x1 = x2
So f(x)= 6x + 1 is a one to one function
Answer:
#10:
burger: $7.50
fries and drink: 2.50
idk about #9 tho sry
Step-by-step explanation:
Division is ur answer..
examples...
300 and 30......300/30 = 10....so 300 is 10 times greater then 30.
5000 and 50....5000/50 = 100...so 5000 is 100 times greater then 50.
70 and 20 ......70/20 = 3.5 ....so 70 is 3.5 times bigger then 20
