What is the exponential regression equation that fits these data?

zlopas [31]

Answer:

Option B) $y = (1.31)(2.8^{x})$ is the correct option.

Step-by-step explanation:

<em>Exponential function is the one where, a constant is raised to the power of x, a independent variable.</em>

Here, only option B and D are such exponential functions, while option A is linear and option C is quadratic in nature.

Now, to verify which option is correct, we will input the values and check which has the least difference between the given values.

Or we can use the cost function,

$J = \frac{((y(i))-y)^2}{2m}$ , to find which function has the least error.

By applying the above results,we find Option B is correct.

Sarah's craft project uses pieces of yarn that are 1/8 yard long. She has a piece of yarn that is 3 yards long. How many 1/8 yar

Verdich [7]

If she used all of her yarn, she'd have 24 pieces. If she wanted 1.25 left, she'd have ten less because 24 • .125 = 8, and 1/4 of eight = 2, and 2 + 8 = 10.

So she'd have 14 pieces.
