Answer:
Step-by-step explanation:
We are given the recursive formula:
This is the recursive formula for an arithmetic sequence.
The explicit formula for an arithmetic sequence is given by:
Where d=3 is the common difference.
We plug in this values to get:
We now expand and simplify to get:
We simplify to obtain:
-2 * 10 or -10 * 2 could be an answer yeah?
Answer:
x/4 - 3 = 12
Step-by-step explanation:
"one fourth of x" is x/4.
Then "three fewer than one fourth of x is 12" becomes, symbolically,
x/4 - 3 = 12
Answer:
Step-by-step explanation:
Sum of interior angles of polygon = (n -2) * 180
Sum of interior angles of hexagon = (6-2)*180 = 4* 180 = 720
4x + 5x +6x +7x + 8x +9x = 180
39x = 180
x = 180/39
x=4.61
Smallest angle = 4x = 4*4.61 = 18.44
Answer:
A variable which can can be represented in numbers is known to be a quantitative variable.
Step-by-step explanation:
A variable is described as a characteristic of an object. Their values may occur more than once for a set of data.
A variable that can be represented in numbers is known to be a quantitative variable. Arithmetic operations can also be performed on these variables i.e. after performing arithmetic operations such as addition, subtraction, multiplication or division, some numbers can still be obtained as the result.
Quantitative variables can also be compared with each other to obtain meaningful results. Quantitative variables are of two types – discrete and continuous.
Discrete variables have whole numbers as their values whereas continuous variables can even have values in between the whole numbers.
Examples of quantitative variables are height, weight, time in the 100-yard dash, the number of items sold to a shopper.
