Answer:

Fifth term

Step-by-step explanation:

The third term is:

20 − (3)² = 11

If the term is negative:

20 − n² < 0

n² > 20

n > √20

n > 4.47

The first term to have a negative value is the fifth term.

Answer:

"34,814" is the correct solution.

Step-by-step explanation:

The given values are:

Intercept coefficient,

$\beta_0 = 23,859$

Production coefficient,

$\beta_1 = 3.13$

Units sold,

x = 3,500

Now,

The total cost will be:

⇒ $\bar{y}=\beta_0+\beta_1 x$

On substituting the estimated values, we get

⇒ $=23,859+3.13\times 3,500$

⇒ $=23,859+10,955$

⇒ $=34,814$

You're dividing where you need to multiply. The intersecting chord theorem says

5(12)=7.5 x

x = 5(12)/7.5 = 8
