What is the length of segment SR? ___units

Mathematics
1 answer:
atroni [7]3 years ago
4 0

Answer:

SR=12\ units

Step-by-step explanation:

we know that

Triangles RTS and QTS are congruent  by SAS postulate

so

SR=SQ

substitute the given values

2x+8=8x-4

Solve for x

8x-2x=8+4

6x=12

x=2

<em>Find out the length of segment SR</em>

SR=2x+8

substitute the value of x

SR=2(2)+8=12\ units

1) Mean of the set of data: 29.88

2) Mean absolute deviation: 10.13

3) See explanation

Step-by-step explanation:

1)

The mean of a set of data it is calculated as

\bar x = \frac{1}{N}\sum x_i

where

N is the number of data in the set

x_i is the value of each point in the  dataset

For the set of data in this problem, we have:

x_i =[28, 45, 12, 34, 36, 45, 19, 20]

And the number of values is

N = 8

Therefore, we can calculate the mean:

\bar x = \frac{1}{8}(28+ 45+ 12+ 34+ 36+ 45+ 19+ 20)=\frac{239}{8}=29.88

2)

The mean absolute deviation of a set of data is given by

\delta = \frac{1}{N}\sum |x_i-\bar x|

where

N is the number of values in the dataset

x_i are the single values

\bar x is the mean of the dataset

The dataset here is

x_i =[28, 45, 12, 34, 36, 45, 19, 20]

The mean, calculated in part 1), is

\bar x = 29.88

And

N = 8

Therefore the mean absolute deviation is

\delta = \frac{1}{8}(|28-29.88|+|45-29.88|+|12-29.88|+|34-29.88|+|36-29.88|+|45-29.88|+|19-29.88|+|20-29.88|)=\frac{81}{8}=10.13

3)

The mean of a dataset is the sum of the single values of the dataset divided by the number of values. The mean represents the value \bar x for which, if the dataset would have N values all equal to \bar x, the sum of the values of the dataset would be the same as the sum of the actual values.

The mean absolute deviation for a set of data represents the average of the absolute deviations of the single points from the mean of the dataset. This quantity gives a measure of the "dispersion" of the points around the mean: in fact, the larger the mean absolute deviation is, the more the points are "spread" around the mean of the dataset. Instead, if the mean absolute deviation is small, it means that the points are closer to the mean value.

A rectangular garden is extended 4% on the long sides and 8% on the short sides. To the nearest hundredth of a percent, by what
liq [111]

Answer: 12.32%

Step-by-step explanation:

1. x is the original long side and y is the original short side.

2. The area of the original rectangle is xy.

3. The rectangle is extended 4% on the long sides and 8% on the short sides. therefore, the new long side is:

\frac{104}{100}x=\frac{26}{25}x

4. And the new short side is:

\frac{108}{100}y=\frac{27}{25}y

5. The new area is:

(\frac{26}{25}x)(\frac{27}{25}y)=\frac{702}{625}xy

6. The percentage of increase is calculated by substracting the new area and the original area:

\frac{702}{625}xy-xy=0.1232xy

7. The result is:

(0.1232)(100)=12.32%
