4.95 x 4 = 19.80
55.29 - 19.80 = 35.49
35.49 / 2.73 = 13
You and your friends purchased 13 gallons of gas
0.4=4/10
4/10=2/5
The answer is 2/5. To get that write 0.4 as a fraction and divide both numbers by the greatest common factor, which in this case is two.
Hope this helps! If not plz comment and I'll try to explain more☺
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.
Sin 60⁰= x/10
x=10*sin 60⁰
x=10*(√3/2)=5√3
x=5√3
Answer is x=5√3.
In the context of data models, relationships among records in a hierarchical model are called Branches. This is further explained below.
<h3>What
are data models,?</h3>
Generally, The act of generating a visual representation of either a whole information system or portions of it in order to express the linkages between different data points and structures is known as data modeling.
In conclusion, When discussing data models, the connections between different records in a hierarchical structure are referred to as "Branches."
