The difference of the square of a number and 28 is equal to 3 times that number. Find the negative solution.

Talja [164]

Answer: -4

Step-by-step explanation:

3 times that number→3x

Difference of the square of a number and 28→x^2-28

x^2 −28= 3x

-3x =-3x

x^2-3x-28=0

(x-7)(x+4)=0

x-7=0

x+4=0

x=7 x=-4

{Negative Solution: }-4

Negative Solution: −4

What does the number in the bottom right hand corner of a two-way frequency table represent?; What is a 2 way frequency table?;

Leni [432]

The solutions for all three questions regarding two-way frequency tables are given below.

A two-way frequency table is a method used to visually represent two sets of categorical data. Unlike one-way frequency tables which have only one categorical variable, these have two. The important parts of a two-way frequency table are the topmost rows that have the name of the category. The leftmost column also has the categories listed. The middle columns and rows contain the data (frequency).

The number in the bottom right-hand corner of a two-way frequency is used to denote the total number of data points that are there in the data set given. This is also equal to the sum of the total rows/columns.

enot [183]

Consider, please, this solution/explanation:
1. suppose, that number of cars is 'x', numbers of buses is 'y'.
2. according to the condition 'a total of 32', it means that x+y=32. This is the 1st equation.
3. according to the condition in one car are 3x persons, in one bus are 27y persons, and totaly 3x+27y=408 people. This is the 2d equation.
4. if to solve the system of two equations:
$\left \{ {{x+y=32} \atop {3x+27y=408}} \right. \ =\ \textgreater \ \ \left \{ {{x=19 (cars)} \atop {y=13(buses)}} \right.$

Answer: 13 - b., 19 - c.
