First you have to canceled out the fours from both side 4x/4-12/4 so x=3 then you do the same thing to the 7x-18

4x-12.
4x/4-12/4. So x=3
The fours cancelled out

7x-18
7x/7-18/7. So x= 2 4/7
The sevens cancelled out

Consider the following frequency distribution.
Zarrin [17]

Answer:

Class interval                            10-19 20-29 30-39 40-49 50-59

cumulative frequency               10      24       41        48       50

cumulative relative frequency 0.2   0.48     0.82    0.96      1

Step-by-step explanation:

1.

We are given the frequency of each class interval and we have to find the respective cumulative frequency and cumulative relative frequency.

Cumulative frequency

10

10+14=24

14+17=41

41+7=48

48+2=50

sum of frequencies is 50 so the relative frequency is f/50.

Relative frequency

10/50=0.2

14/50=0.28

17/50=0.34

7/50=0.14

2/50=0.04

Cumulative relative frequency

0.2

0.2+0.28=0.48

0.48+0.34=0.82

0.82+0.14=0.96

0.96+0.04=1

The cumulative relative frequency is calculated using relative frequency.

Relative frequency is calculated by dividing the respective frequency to the sum of frequency.

The cumulative frequency is calculated by adding the frequency of respective class to the sum of frequencies of previous classes.

The cumulative relative frequency is calculated by adding the relative frequency of respective class to the sum of relative frequencies of previous classes.

Write the equation of this circle in standard form.<br> please give answer?
Law Incorporation [45]

Given the center (x_0,y_0) and the radius r of a circle, its equation is

(x-x_0)^2+(y-y_0)^2=r^2

In your case, the center is (-4,0), and the radius is 2. Plug these values into the generic formula and you'll get the equation.
