Answer:

The Answers from up to down should be 11,3,-3,-12

Step-by-step explanation:

I'm just going to explain the first 2 boxes because the rest is repeat. In the first box you have the value of x so you want to plug it into the equation getting y=-2/3*(-6)+7 getting answer 11. In the box its the opposite, you do -2/3x+7=5 then solve for x

-2/3x=-2

      x=3

the rest is the same concept!

Write the equation of the line in fully simplified slope Intercept form.
andre [41]

Answer:

y = -0.83x - 2

Step-by-step explanation:

Slope intercept form is y = mx+b.

M is the slope: In this case the slope (rise/run) is 10/12. However, the slope is decreasing is that would make it negative.

Now we have: y = -0.83x + b

B represents the y-intercept. The y-intercept here is -2. So our final equation is:

y = -0.83x - 2

Assuming a 90% confidence level, the margin of error is approximately?
elena-s [515]

Answer:

  0.3

Step-by-step explanation:

The margin of error is calculated as ...

  (standard deviation)/√(sample size) × (z*-score)

where the z*-score is chosen based on the desired confidence level.

Here, you have ...

  • standard deviation = 2.7
  • √(sample size) = √225 = 15
  • z*-score for 90% confidence level = 1.645

Putting these values in the above expression for margin of error gives ...

  2.7/15·1.645 = 0.2961 ≈ 0.3
