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.)
Step-by-step explanation:
1. A = lw
- l = A/w
- l = (x²+7x +12) / (x + 3) =
- (x + 4)(x + 3)/(x + 3) =
- x + 4 m
2. V = lwh
- lw = V/h
- lw = (x³ + 12x²+ 47x + 60) / (x + 3) =
- (x³+ 3x² + 9x² + 27x + 20 x + 60) /(x + 3) =
- (x + 3)(x² + 9x + 20) / (x + 3) =
- x² + 9x + 20 cm²
3. A = bh
- h = A/b
- h = (f³-8) / (f-2) =
- (f - 2)(f² + 2f + 4)/(f-2) =
- f² + 2f + 4 cm
4. A = p*c
- c = A/p
- c = (3x³- 4x² + 2x + 4) / (x²- 2x + 2) =
- (3x³ - 6x² + 6x + 2x² - 4x + 4) /(x² - 2x + 2) =
- (x² - 2x + 2) (3x + 2) / (x² - 2x + 2) =
- 3x + 2 cans
5. A = lw
- l = A/w
- l = (x² + 5x - 6)/(x + 2) =
- (x - 1)(x + 6)/(x + 2) m

Answer:
Step-by-step explanation:
we see that y = -3x-3
substitute that into the other equation to get
-3x-3 = 2x+7
-5x = 10
x = -2
so, y = -3(-2)-3 = 3
check to make sure (-2,3) solves both equations.
