Step-by-step explanation:

x/(2x - 4) - (2x - 11)/(x + 2) = 5/8
x/(x - 2) - (4x - 22)/(x + 2) = 5/4
x(x + 2) - (4x - 22)(x - 2) = 5/4(x + 2)(x - 2)
4(x² + 2x - 4x² + 8x + 22x - 44) = 5(x² - 4)
4(-3x² + 32x - 44) = 5x² - 20
- 12x² + 128x - 176 - 5x² + 20 = 0
- 17x² + 128x - 156 = 0
17x² - 128x + 156 = 0
x = (64 ± 38)/17
x = 6 or x = 26/17

Bought a new car lately? The following table presents the number of vehicles sold in a certain country by several manufacturers

ella [17]

Answer:

The Relative Frequency Table is:

<u> Manufacturer Relative Frequency </u>

General Motors 0.242

Ford 0.208

Chrysler LLC 0.148

Toyota 0.177

Honda 0.116

Nissan 0.109

Step-by-step explanation:

To find out the relative frequency we need to use the formula:

Relative Frequency = Frequency / Sum of All Frequencies

We can find the sum of all the frequencies by adding all the sales for the year 2013.

Sum of Frequencies for 2013 = 225,650 + 194,068 + 138,085 + 164,423 + 107,526 + 101,113

Sum of Frequencies for 2013 = 930865 cars

Now we can compute the relative frequencies for each of the manufacturers as follows:

General Motors: 225650/930865 = 0.242

Ford: 194068/930865 = 0.208

Chrysler LLC: 138085/930865 = 0.148

Toyota: 164423/930865 = 0.177

Honda: 107526/930865 = 0.116

Nissan: 101113/930865 = 0.109

Relative Frequency Distribution Table for the 2013 sales:

Manufacturer Relative Frequency

General Motors 0.242

Ford 0.208

Chrysler LLC 0.148

Toyota 0.177

Honda 0.116

Nissan 0.109
