Mathematics
1 answer:
AURORKA [14]3 years ago
7 0

Answer:

1) y = 115°

2) x = 120°

3) x = 163°

Step-by-step explanation:

  • the sum of the interior angles of a figure = (number of sides - 2) * 180

1)

the sum of the interior angles of this figure = (5 - 2) * 180 = 540°

the fifth angle = the sum of the interior angles - the sum of the four angles

the fifth angle or y = 540 - (90 + 135 + 112 + 88) = 115

2)

the sum of the interior angles = (6 - 2) * 180 = 720°

x = 720 - (90 + 90 + 140 + 150 + 130) = 120

3)

the sum of the interior angles = (5 - 2) * 180 = 540°

x = 540 - (68 + 121 + 103 + 85) = 163

If point B, shown on the coordinate plane below, is reflected over the y-axis to create B’, what will be the coordinates of B’?(
Reil [10]

Solution

- The transformation for reflection over the y-axis is given below:

(x,y)\to(-x,y)

- We have been given the coordinate of B to be (-5, -2) as shown below:

- Thus, applying the transformation formula given above, we have:

\begin{gathered} (x,y)\to(-x,y) \\ (-5,-2)\to(-(-5),-2)=(5,-2) \end{gathered}

- Thus, the reflected point B' is

(5,-2)

- This is shown below:

During the first 13 weeks of the television season, the Saturday evening 8:00 p.m. to 9:00 p.m. audience proportions were record
SpyIntel [72]

Part 1: Do not reject H0. There has not been a significant change in the viewing audience proportions.(The above conclusion holds as the p-value is greater than the significance level of 0.05)

Part 2:

H0:  

Ha:  

Part 3: The test statistic is given as 3.0081.

Part 4: The p-value is given as  0.39037

Step-by-step explanation:

As per the data

Part 2

H0:  

Ha:  

Part 3

As per the sample is of 300 homes, the expected values are given as

ABC=p(ABC)*300=0.30*300=90

CBS=p(CBS)*300=0.27*300=81

NBC=p(NBC)*300=0.26*300=78

IND=p(IND)*300=0.17*300=51

Now the values actually are given as

ABC=94

CBS=71

NBC=88

IND=47

So the test static is given as

So the test statistic is given as 3.0081.

Part 4

Now the degree of freedoms are given as 4-1=3

and chi square  is given as 3.0081 so for α = 0.05 , the p-value is given as  0.39037

Part 1.

As the value of p in part 4 is greater than the value of α = 0.05, thus Do not reject H0. There has not been a significant change in the viewing audience proportions.(The above conclusion holds as the p-value is greater than the significance level of 0.05)
