How can data be described by a single number

Mathematics
1 answer:
SpyIntel [72]3 years ago
3 0

Answer:

the arrangement of the values of a data set. measures of center [measures of central tendency] describes how data looks at the center; summarizes all of its values with a single number.

Step-by-step explanation:

Data that cannot be described using a single number are often shoehorned into random vectors of real-valued random variables, although there is an increasing tendency to treat them on their own. No seriously there is lol

Solving for x, please help
Sergeeva-Olga [200]

Answer:

x = 5,-2

Step-by-step explanation:

Multiply the whole equation by 3(x+1) to get rid of the denominator.

\large{ \frac{x + 2}{3} \times 3(x + 1) =  \frac{2(x + 2)}{x + 1}  \times 3(x + 1)} \\ \large{(x + 2)(x + 1) = 2(x + 2) \times  3} \\  \large{ {x}^{2}  + 3x + 2 = 6(x + 2)} \\  \large{ {x}^{2}  + 3x + 2 = 6x + 12}

Then we solve the equation.

\large{ {x}^{2}  + 3x + 2 - 6x - 12 = 0} \\  \large{ {x}^{2}  - 3x - 10 = 0} \\  \large{(x - 5)(x + 2) = 0} \\  \large{x = 5, - 2}

Since we are also solving rational equation, make sure that x ≠ -1 for this problem. Because if x = -1, the denominator is 0 which is undefined. Since our solutions are x = 5,-2 and not -1. Therefore the answer is x = 5,-2
