Equation of regression line is in the form:
y = mx + c
Where y = predicted variable ;
c = intercept ; m = slope or gradient ; x = predictor variable
Using The correlation Coefficient calculator :
The regression equation obtained is :
ŷ = 0.2754X - 0.77028
Rounding values in our regression output to 2 decimal places :
y = 0.28X - 0.77
Hence best model to make prediction :
y = 0.28X - 0.77
Answer:
x²(x-2) or x²(x+1)
Step-by-step explanation:
Even though the figure showing the prism is missing, we can already make a few assumptions about how to answer the question.
It tells us that it is an oblique square prism. Using this information, we can assume that of the dimensions (length, width and height), length and width are assumed to be equal.
If the unknown dimensions needed to calculate volume are written as:
Volume = X x Y x Z (and length and width are the same, we can simplify)
Volume = X² x Z
Hence we need a x² in our answer.
In order to narrow it down between the two remaining options, the diagram is needed. If the height is shorter than the length, then the answer would be x²(x-2), however if the height is longer than the length, then the answer would be x²(x+1).
Answer:
1) selling price is $62.50 and 2) total cost would be $66.25
Step-by-step explanation:
C is a vertical angle which the vertical side is corresponding to the vertical side of x°.
105°+54°+y°=180°
159°+y°=180°
y°=21°
Meaning, x=21°.
-5c^2-3c+4 This polynomial is in standard form, now, and the leading coefficient is 5, because it is the coefficient of the first term. Degree is 2, due to -5c^2.
