Answer:
a= 13.15 years
b= -0.62 years/$
Step-by-step explanation:
Hello!
Given the variables
Y: Age of a used car. (years)
X: Price of a sold used car. ($000)
The linear regression model is:
E(Y)= α + βXi
The estimated equation is:
^Y= a + bXi
a= 13.15 years
b= -0.62 years/$
Then ^Y= 13.15 - 0.62Xi
Mean Y= 8.92
Mean X= 6.91
∑Y= 107
∑Y²=1009
∑X=82.90
∑X²=615.29
∑XY=712.9
Hope it helps!
The answers are:
<span>ƒ(x) = x - .15x
</span><span>Sale = Original - .15(Original)
</span><span>y = .85x
Let sale price be f(x) and x be the original price. Discount was 15% = 0.15
f(x) = x - 0.15x
If f(x) is sale and x is the original, then:
</span><span>Sale = Original - .15(Original)
Let sale price be y and original price x:
y = x - 0.15x
y = 1 * x - 0.15 * x
y = (1 - 0.15) * x
y = 0.85x</span>

Answer:
There's a probability that thei answer is C
The factors of the equation are
Step-by-step explanation:
We need to factor the quadratic trinomial.
We will do factorization by braking the middle term such that adding those number we get middle term (-3x) and multiplying those numbers we get (-18x^2)
Solving:
So, the factors of the equation are
