Answer:

y = 17/6 x - 40/3

Step-by-step explanation:

Slope-intercept form: y = mx + b

First, let's find the slope:

slope formula: (y2-y1) divded by (x2-x1)

(4, -2) and (8, -9)

(-9 - 8) divded by (-2 - 4) = 17/6

We found m, now we have to find b.

The new equation: y = 17/6 x + b

Insert any of the two points, in this case, I'll insert (4, -2)

-2 = 17/6 (4) + b

-2 = 68/6 + b

b = -2 - 68/6

b = -40/3

Overall equation: y = 17/6 x - 40/3

Answer:

The first one : decay

The second one : growth

When the argument of the exponential expression is bigger that 1 then it represents a growth

When it's less than 1 and above 0 then it's a decay

You collect a random sample of size n from a population and calculate a 90% confidence interval. Which of the following strategi
Daniel [21]

Answer:

Decrease the sample size.

Step-by-step explanation:

Margin of error is:

ME = CV × √(σ / n)

where σ is the population standard deviation, or:

ME = CV × √(p (1 − p) / n)

where p is the proportion.

In each case, the margin of error is directly proportional to the critical value, and inversely proportional to √n.

Lowering the confidence level will lower the critical value, which will decrease the margin of error.  Decreasing the sample size will increase the margin of error.
