Answer:
The correct option is c.
Step-by-step explanation:
The regression line representing the price of very high quality diamonds is:
It is provided that a diamond seller lists a very high quality diamond weighing 0.8 carats at a price of $9,999.
Compute the predicted price of the diamond weighing 0.8 carats as follows:
The predicted price of the diamond weighing 0.8 carats is $10,310.60.
In regression, the difference amid the observed-value of the dependent-variable (y) and the predicted-value () is known as the residual (e).
Compute the residual value as follows:
The residual value is -$311.60.
Thus, it can be concluded that the model over-predicts the price of this diamond because the residual is negative.
The correct option is c.
Answer: Only Option 'A' and 'B' are correct.
Step-by-step explanation:
Since we have given that
Number of calories she consumed at breakfast = 400
Number of calories she consumed at lunch = 350
Let number of calories she consumed at dinner be x
According to question,
She consumes of her daily calories at dinner,
So, it becomes,
so, Number of calories she consumed at dinner is given by
And by option 'B' we get,
so, only Option 'A' and 'B' are correct.
Answer:
D
Step-by-step explanation:
Difference of cubes is as follows
x^3-y^3=(x-y)(x^2+y^2+xy)
*notice how the sign in the origonal equation is the same for the first part but then flipped for the second*****
8 can be rewritten as 2^3 so we have
x^3-2^3 which means that we can use the template from before
(x-2)(x^2+2^2+2x)
simplify the 2^2 into 4 and put the variables in front to get
(x-2)(x^2+2x+4)
This is the same as D
