Answer:
Relative frequency
Step-by-step explanation:
In a <u> relative frequency </u>distribution, the frequency of a class is replaced with a proportion or percent.
A relative frequency distribution displays how the proportion of totality of the observations related to each class is correlated to the probability distribution. A relative frequency distribution shows the proportion of times a value occurs in each class. It can be determined by the division of the frequency with the total number of data values.
1. x - 8= 47
47 + 8 = 55
55 = x
2. 7x = 28
28 divided by 7 = 4
x = 4
3. 6x - 5 = 31
31 + 5 = 36
36 divided by 6 = 6
x = 6
4. x + 4 = 12
12 - 4 = 8
x = 8
Answer:
x = -2
Step-by-step explanation:
hello :
the system is : 3x-5y=10 ...(*)
-x+3y=-6...(**)
multiply (**) by : 3 you have : -3x+9y = -18 ...(***)
add (*) and (***) : 4y= -8 so: x = -2
