Answer:
Meaning of Explicit rule , is the general rule for a sequence.
The given sequence is defined as,
----(1)
Common Difference(d) of an airthmetic Sequence= N th term - (N-1) th term
Equation 1 can be written as,
General rule or explicit rule for this sequence is given as:
In this problem, the x intercept is 3.5 because the line crosses through the x axis at the point (3.5,0)
Answer:
30 square feet.
Step-by-step explanation:
We have to find the main area of the rectangle to determine the changes.
We know, Area of a rectangle = Length × Width
Given,
Length = 12 feet
Width = 5 feet
Therefore, the area of the rectangle = (12 × 5) Square feet.
The area of the rectangle = 60 square feet.
Now, if the length of the rectangle increased by 25%, the new length would be = 12 feet (12 feet × 25%) = 12 feet + 3 feet = 15 feet.
If the width increased by 20%, the latest width would be = 5 feet + (5 feet × 20%) = 5 feet + 1 foot = 6 feet.
The new area of that rectangle = (15 × 6) square feet = 90 square feet.
The changes of area from the previous rectangle is = (90 - 60) square feet = 30 square feet.
9x - 37 = - 118
add 37 to both sides
9x - 37 + 37 = -118 + 37
simplify
9x = -81
divide both sides by 9
9x/9 = -81/9
simplify
x = - 9
answer
x = -9
Answer:
Option a) u is called the "error term". It is the error we make in prediction
Option d) x is called the independent variable because x is independent from y and u.
Step-by-step explanation:
We are given the following information in the question:
where y is the dependent variable, x is the independent variable.
: It is the value of y when x is zero, that is y-intercept.
: It is the coefficient of x in predicting the dependent variable y.
u is the error term.
- An error term represents the margin of error.
- It refers to the sum of the deviations within the regression line, that is the difference between the predicted value and the observed value of y.
Thus, Option A) u is the error term and Option D) x is called the independent variable because x is independent from y and u are the correct answer.
