Slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
so
slope beteen (7,-11) and (-5,-8) is

(-8-(-11))/(-5-7)=(-8+11)/(-12)=3/-12=-1/4

slope=-1/4

Statement 3 and 4 are true as Figures 1 and 2 are not congruent and Figures 1 and 3 are not congruent

<h3>What are Congruent Figures ?</h3>

The figures that are similar in shape and size or can be mapped into one another , such figures are called Congruent Figures.

The graph has been plotted on the basis of given data.

The plot can be seen in the graph attached with the answer.

The statements that are true according to the given data is

Statement 3 and 4 are true as

Figures 1 and 2 are not congruent because figure 1 cannot be mapped onto figure 2 using a sequence of rigid transformations.

50 POINTS! The fifth term of an arithmetic sequence is 11 and the tenth term is 41. What is the first term?
Oxana [17]

<em><u>The common difference d is </u></em>

  • (41–11) / (10–5) = 6.

<em><u>The first term is</u></em>

  • 11 - 6(5–1) = -13.

<em>so , the first term is -13 </em>

Vlada [557]

Answer:

The test statistic for this test is 3.82.

Step-by-step explanation:

The null hypothesis is:

H_{0} = 8500

The alternate hypotesis is:

H_{1} > 8500

Our test statistic is:

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the sample mean, \mu is the value tested at the null hypothesis, \sigma is the standard deviation of the population and n is the size of the sample.

In this question:

X = 8745, \mu = 8500, \sigma = 1200, n = 350

So

t = \frac{8745 - 8500}{\frac{1200}{\sqrt{350}}} = 3.82

The test statistic for this test is 3.82.
