Answer:

<em>x = 11.83°</em>

Step-by-step explanation:

<u>Equations</u>

The figure shows two parallel lines crossed by a line. We have completed the figure with another variable y. Please see the attached image.

Angles y and 4x+28 are linear, thus their sum is 180°:

y + 4x + 28 = 180

Angles y and 8x + 10 are corresponding, thus

y = 8x + 10

Substituting:

8x + 10 + 4x + 28 = 180

Simplifying:

12x + 38 = 180

Subtracting 38:

12x = 142

Dividing by 12

x = 11.83°

Assume the sample below is a perfectly random sample of students at a school. How much greater is the mean of the
igor_vitrenko [27]

Answer:

0.75

Step-by-step explanation:

The table is not well presented (See Attachment)

There are at least two approaches to this question

Method 1:  

Steps

1. Calculate the mean of reported heights

Mean of reported heights = (61+68+57.5+48.5+75+65+80+68+69+63)/10

Mean of reported heights = 655/10

Mean of reported heights = 65.5

2. Calculate the mean of measured heights

Mean of measured heights = (62 + 68 + 56.5 + 47 + 72 + 65 + 78 + 67 + 69.5 + 62.5)/10

Mean of measured heights = 647.5/10

Mean of measured heights = 64.75

3. Get their difference

Difference = Mean of reported heights - Mean of measured heights

Difference = 65.5 - 64.75

Difference = 0,75

Method 2: Calculate the mean of their difference

Mean of difference = Sum of difference / Number of observations

Mean of difference = (-1 + 0 + 1 + 1.5 + 3 + 0 + 2 + 1 – 0.5 + 0.5)/10

Mean of difference = 7.5/10

Mean of difference = 0.75

Note that in both cases, the result is 0,75.

Hence, the reported heights at the school is 0.75 greater than the actual measured height
