Answer:
a. x
b. 35
c. 45
d. y
Explanation:
a. The independent variable is not dictated by any other variable. x is the only variable here that fits that description is x.
b. A coefficient is a constant that multiplies any variable. 35 multiplies x, so it is a coefficient.
c. A constant is a number that cannot change and isn't a coefficient. 45 cannot be changed.
d. The dependent variable is dictated by other variables. y is dictated by x, so it is the dependent variable.
Answer:
The first option is correct, (-2y + 5x) / (3x - 2y)
Step-by-step explanation:
Answer:
5.6
Step-by-step explanation:
Given :
Quality rating for 8 movies :
5.6, 7.9, 7.0, 5.9, 7.8, 6.2, 6.4, 5.2
Let rating for the 9th movie = x
Average quality rating olfor the 9 movies = 6.4
To find x :
Sum of all ratings / number of ratings = 6.4
(5.6 + 7.9 + 7.0 + 5.9 + 7.8 + 6.2 + 6.4 + 5.2 + x) / 9 = 6.4
(52 + x) / 9 = 6.4
52 + x = 57.6
x = 57.6 - 52
x = 5.6
-7/15.
You multiply the numerator and denominator to get -21/45. To simplify, divide each by the greatest common factor, which is three, to get -7/15.
