The range of a function is the set of y-coordinates.
The y-coordinates are 1, 4, 4, 2.
In a set you only put each number once, so the range is {1, 2, 4}.
The answer is- -5.55, -5.5, -3, and 5.45
Answer:
The linear regression model that will determine approximate Fat Grams (y) as a function of Calories (x) is given by
y = 0.054 x - 2.105
Hence the correct option is B.)
Step-by-step explanation:
Step 1: Find X⋅Y and as it was done in the table below.
Step 2: Find the sum of every column:
ΣX = 1560, ΣY = 67, ΣX.Y = 14860 , ∑(
) = 337600
Step 3: Use the following equations to find a and b:
a = = -2.105
b =
= 0.054
Step 4: Substitute a and b in regression equation formula
y = a + b⋅x= −2.105 + 0.054⋅x
The linear regression model that will determine approximate Fat Grams (y) as a function of Calories (x) is given by
y = 0.054 x - 2.105
Hence the correct option is B.)
