Answer:
10x^2 -276.67x - 593.34
Step-by-step explanation:
is it like that ?
5(x-30-3/9)(2x+4)
(5x- 148.335)(2x+4)
10x^2 -296.67x +20x -593.34
10x^2 -276.67x - 593.34
Answer:
The yearly rate of appreciation of the comic book is r=0.017 or r=1.7%
Step-by-step explanation:
we have
This is a exponential function of the form
where
a is the initial value
b is the base
In this problem
a=$1,350
b=1.017
Remember that
b=1+r
so
1+r=1.017
r=1.017-1=0.017
therefore
The yearly rate of appreciation of the comic book is r=0.017 or r=1.7%
Answer: you have it right
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Never ending non repetitive, could not be made a fraction
Answer:
a) ρ (X,Y) = 0.125
b) The linear relationship is weak because ρ (X,Y) is almost 0
c) There is a positive linear relationship because ρ (X,Y) > 0
Step-by-step explanation:
The Pearson correlation coefficient is calculate as :
ρ (X,Y) = (σXY) / (σX)(σY)
-1 ≤ ρ ≤ 1
When ρ = 0 there is no linear relationship between the variables. This does not mean that the variables are independent.
When ρ = 1 the linear relationship is perfect positive. ρ = 1 means a direct relation between X and Y : When X increases also Y increases in constant proportion. When Y increases also X increases in constant proportion.
When ρ = -1 the linear relationship is perfect negative. ρ = -1 means a inverse relation between X and Y : When X increases Y decreases in constant proportion. When Y increases X decreases in constant proportion.
In our exercise ρ (X,Y) = 13.44 / (15.57)(6.90) = 0.125
a) ρ (X,Y) = 0.125
b) The linear relationship is weak because ρ (X,Y) is almost 0
c) There is a positive linear relationship because ρ (X,Y) > 0
