Since the "size in square feet" is on the X-axis it is represented by the X in the equation. And Y is expected property tax

It is giving you a X-value of 3100. So you just have to plug 3100 into the X spot and solve for Y

y=.392(3100)+638.118
y=1853.318

So the third answer.

Solve 7w – 3r = 15 for r. Show your work.

uysha [10]

What's w?

Well without W, we just have to trial and error.

R could be 2.

7w - 3r = 15
7w - 3(2) = 15
7w - 6 = 15
7w = 21
/7 /7
w = 3

So if W = 3, R could be 2.

The p-value for a two-sided test of the null hypothesis H0: μ = 10 is 0.06. Would a 95% confidence interval for μ include the va

sesenic [268]

Answer:

- Yes. A p-value of 0.06 indicates that the results observed are not statistically significant at the 5% level, so the 95% confidence interval will include 10.

Step-by-step explanation:

A p-value of 0.06 at 0.05 significance means we fail to reject the null hypothesis that H0: μ = 10 since p-value>p-critical.

This also means that the result is not statistically significant at 0.05 significance level.

Thus, 95% confidence interval for μ includes 10.

Please help me with domain and range of graphs Part 1

dybincka [34]

Answer:

see the attached for domain
Range: (-∞, 4], [3, ∞), [-3, 1]

Step-by-step explanation:

The domain is the horizontal extent of the graph. When the graph has arrows on the end, it extends to infinity in the indicated direction.

The range is the vertical extent of the graph.

Left Graph

We assume the curve is intended to touch, not cross, the line y=4, so the range is ...

range: (-∞, 4]

Middle Graph

We assume the graph continues along the line y=3 to the right indefinitely. Then this value is the minimum of the range.

range: [3, ∞)

Right Graph

The low point on the graph is at y=-3, and it looks like the graph continues to the right along the line y=1. Then the range is ...

range: [-3, 1]
