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:
17.5 milies
Step-by-step explanation:
80/4
=20/1
This means that Ivan can walk 1 mile in 20 minutes
To figure out how many miles Ivan can walk in 345 if she continues at that pace you divide 345 by 20
345/20 = 17.5
This means Ivan can walk 17.5 milies in 345 minutes
Answer:
Step-by-step explanation:
If DE = 4x+10,EF =2X -1, and DF= 9x - 15 find DF
(de + ef ) - df = 2e || 2e/2 = e || ed - e = d || ef - e = f || f + d = df
de + ef = 6x + 11 || (6x +11) - df = -3x -6 || 2e/2 = -3x/2 - 3 || (-3x/2 - 3) - de = x/2 + 7|| (- 3x/2 - 3) - ef = -x/2 - 1|| d + f = 6
Answer:
V = 301 ft^3
Step-by-step explanation:
The volume of a cone is given by
V =1/3 pi r^2 h
We know pi = 3.14 r =6 and
We need to determine h
We can find h from the Pythagorean theorem where 6 is a leg and 10 is the hypotenuse
h^2 +6^2 = 10^2
h^2 +36 = 100
h^2 = 64
Taking the square root of each side
h = 8
V =1/3 pi r^2 h
V = 1/3 (3.14) (6)^2 * 8
V = 301.44 ft^3
Rounding to the nearest cubic foot
V = 301 ft^3
Answer:
Max: 500
Min: 492
Step-by-step explanation:
Her dog is on an 8 meter leash but it doesn't necessarily take up the whole leash. The most is could be closer to her house than Morgan is 8 meters, the least is 0.
Most: 500-0=500
Min: 500-8=492
