First you would want to find the slope. The equation for slope is y2-y1/x2-x1.

So the slope would be 5-3/ 6-(-4). Two negatives make a positive so it would be 5-3/6+4 or 2/10 which can be simplified to 1/2.

Next you used the point slope form equation. y-y1 =m(x-x1)

m is the slope we just found: 1/2
the equation would be = y-3=1/2(x-(-4))

two negatives make a positive so the equation would now be y-3=1/2(x+4)

You then distribute the x to what is in the parenthesis

y-3=1/2x+2
then add the 3 to both sides

you’re equation should be y=1/2+5

Sloan [31]

Answer:

Confidence level is (380.7133, 533.2867)

Step-by-step explanation:

Responses in number of tongue flicks per 20 minutes of lizards, are: 727,217, 268, 438, 625, 319, 200, 591, 574, 727, 693, 336, 302, 761, 268, 353, 370

n = 17

Mean (μ) is:

$\mu=\frac{{\Sigma}x}{n} = \frac{727+217+ 268+ 438+ 625+ 319+ 200+ 591+ 574+ 727+ 693+ 336+ 302+ 761+ 268+ 353+ 370}{17} = 439.3529$

Standard deviation (σ) is:

$\sigma=\sqrt{\frac{\Sigma(x-\mu^2)}{n} } =\sqrt{\frac{(727-457)^2+(217-457)^2+...+(370-457)^2}{17} } =191.2$

The confidence interval (c) = 90% = 0.9

$\alpha=1-0.9=0.1\\\frac{\alpha }{2} = 0.05\\Z_{\frac{\alpha }{2} }=1.64$

Margin of error (e) = $=Z_{\frac{\alpha}{2} }*\frac{\sigma}{\sqrt{n} }=1.64*\frac{191.2}{\sqrt{17} }=76.2867$

Confidence level = μ ± e = 457 ± 76.2867 = (380.7133, 533.2867)

Domain and Range: determine the domain and Range for each graph

bija089 [108]

Given:

The graph of a function.

To find:

The domain and range of the given graph.

Solution:

Domain is the set of x-values or input values.

From the given graph it is clear that, the graph is defined for the interval (-4,4).

But there is a closed circle at x = -4 and an open circle at x = 4. It means, -4 is included and 4 is not included in the solution set.

Domain: [-4,4)

Domain: $-4\leq x$

Range is the set of y-values or output values.

From the given graph it is clear that, the output values are lie in the interval (-3,4).

But there closed circle at x = -3 and x = 4. It means, -3 and 4 are is included in the set of output values.

Range: [-3,4]

Range: $-3\leq y\leq 4$

Therefore, domain is $-4\leq x$ and range is $-3\leq y\leq 4$ .
