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.)
Is 495 just multiply 5 by 45 and then sum 6 by 45

Answer:
4/9, or 0.4∞
but 0.4∞ has a repeating decimal, so the expanded form is ∞ also
Answer:
142.2 meters.
Step-by-step explanation:
We have been given that a box measures 70 cm X 36 cm X 12 cm is to be covered by a canvas.
Let us find total surface area of box using surface area formula of cuboid.
, where,
= Length of cuboid,
= Breadth of cuboid,
= Width of cuboid.
Therefore, the total surface area of box will be 7584 square cm.
To find the length of canvas that will cover 150 boxes, we will divide total surface area of 150 such boxes by width of canvass as total surface area of canvas will also be the same.
Let us convert the length of canvas into meters by dividing 14220 by 100 as 1 meter equals to 100 cm.
Therefore, 142.2 meters of canvas of width 80 cm required to cover 150 such boxes.
