9.973 rounded to the nearest hundredth

DaniilM [7]

The hundredths place is the second digit to the right of the decimal point. In this case, it's 7. When rounding, we want to look at the number in the thousandths place, or 3.

If the number is 0 to 4, you round the hundredths digit down to remain the same. If the thousandths digit is 5 to 9, you round up a number.

In this case, since the number is 3, we just keep 7 the same. So, the answer would be:

9.97

What is the equation of exponential regression equation? Round all numbers you your answer to three decimal places

Monica [59]

Given:

Consider the below figure attached with this question.

The value in the given figure are:

$a=0.2094539899$

$b=2.507467975$

$r^2=0.9435996398$

$r=0.9713905701$

To find:

The exponential regression equation for the given values (Rounded to three decimal places).

Solution:

The general form of exponential regression equation is:

$y=a\cdot b^x$ ...(i)

Where, a is the initial value and b is the growth/decay factor.

The given values are:

$a=0.2094539899$

$b=2.507467975$

Round these numbers to three decimal places.

$a\approx 0.209$

$b\approx 2.507$

Putting $a=0.209, b=2.507$ in (i) to find the exponential regression equation.

$\hat{y}=0.209\cdot 2.507^x$

Hence, the correct option is C.
