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.)

Answer:
0.121 centimeters per second.
Step-by-step explanation:
We are told that in a recent snail race,the winning snail traveled 5.85 cm 3/4 of a minute.
To find the speed at which snail was traveling in centimeters per second, we will divide 5.85 by number of seconds in 3/4 of a minute.
First of all we will find how many seconds are equal to 3/4 of a minute.
Now we will divide 5.85 by 45 to find the speed of snail in centimeters per second.
Therefore, the snail was traveling at a speed of 0.121 centimeters per second.
