Answer:

D. 0.35

Step-by-step explanation:

A correlation coefficient (r), shows the relation of dependent variable with the independent variable,

If it is near to 1 then it is positively stronger,

If it is near to -1 then it is negatively stronger,

While if it near to 0 then it is weaker,

Since, 0.65 > 0.55 > 0.45 > 0.35,

Thus, 0.35 is nearest to 0,

So, we can say that 0.35 is weakest correlation.

Bob's dog needs medication. He told the veterinarian that the dog weighs 30lbs . The medicine is measured as 16mg for each kilog

katrin2010 [14]

Answer:

Bob's dog should be given 216 mg of medicine.

Step-by-step explanation:

Given that:

Weight of dog = 30 lbs

We know that:

1 lb = 0.45 kg

30 lbs = 0.45 * 30 kg

30 lbs = 13.5 kg

Medicine for each kilogram of weight = 16 mg

1 kilogram = 16 mg

13.5 kg = 16 * 13.5 mg

13.5 kg = 216 mg

Hence,

Bob's dog should be given 216 mg of medicine.

Answer:

The length of the box is (x + 1)

The height of the box is (x + 1)

Step-by-step explanation:

The given function representing the volume of the box is presented as follows;

V = x³ + 6·x² + 9·x + 4

The function representing the width of the box, W = x + 4

Therefore, we have;

(x³ + 6·x² + 9·x + 4)/(x + 4) = x² + 2·x + 1

x³ + 4·x²

${}$ 2·x² + 9·x + 4

${}$ 2·x² + 8·x

${}$ x + 4

Therefore, we have;

(x³ + 6·x² + 9·x + 4) = (x + 4) × (x² + 2·x + 1) = (x + 4) × (x + 1) × (x + 1)

(x³ + 6·x² + 9·x + 4) = (x + 4) × (x + 1) × (x + 1)

The width of the box = (x + 4)

The length of the box = (x + 1)

The height of the box = (x + 1).
