To find the area of the arena, you will need to find the areas of the rectangular spaces and the 2 semicircles. Because the formulas are given, I will just substitute in the values and show the work for finding the areas.

To find the perimeter, you will look at the distances of lines that take you around the space. Because two of these spaces are half circles, you will need to find the circumference of the full circle.

Also, the answers need to be given in meters, so all units given in centimeters will be divided by 100 to convert them to meters.

Perimeter:

C= 3.14 x 20 m

C = 62.8 meters

62.8 + 8 + 25 + 8 + 5 + 8 + 10 + 8 + 40= 174.8 meters for the Perimeter

Area:

A = 25 x 8

A = 200 square meters

A = 10 x 8

A = 80 square meters

A = 20 x 40

A = 800 square meters

A = 3.14 x 10^2

A = 314 square meters

Total Area: 314 + 800 + 80 + 200= 1394 square meters

Line L is mapped onto line m by a dilation centered at the origin with a scale factor of 2/5. Line m is represented by y=2x+10 a
Alinara [238K]

Dilating a line changes the size of the line.

The true statement is <em>(c) Line L passes through the origin</em>

The scale of dilation is given as:

\mathbf{k = \frac 25}

The scale represents the slope of line L.

The equation of line M is:

\mathbf{y = 2x + 10}

From the above equation, the slope of line M is:

\mathbf{m = 2}

The two lines do not have the same slope.

<em>This means that, the lines are not parallel and they are not the same line.</em>

<em />

For the two lines to be perpendicular, then the relationship between their slopes is:

\mathbf{m = -\frac 1k}

The above is false, because:

\mathbf{2 \ne -\frac 52}

Hence, the true statement is <em>(c) Line L passes through the origin</em>

<em />

A random sample of 12 students used Method A, and their increase in points averaged 46.31, with a sample standard deviation of 6
Kitty [74]

Answer:

The null hypothesis is   H_o  :  \mu_A  - \mu_B  =  0

The alternative hypothesis is  H_a :  \mu_A - \mu_B > 3  

Step-by-step explanation:

From the question we are told that

  The mean of method A is \mu_A =  46.31

  The standard deviation of method A is  \sigma  = 6.44

   The  mean of method B is  \mu_B   =  42.79

   The standard deviation of  method B  is  \sigma_B  =  7.52

An appropriate set of null and alternative hypothesis to determine whether Method A increases students points by more than 3 points is

The null hypothesis is   H_o  :  \mu_A  - \mu_B  =  0

The alternative hypothesis is  H_a :  \mu_A - \mu_B > 3
