Consider the following frequency distribution:
daser333 [38]

Answer:

        Relative frequency

        0.214

        0.268

        0.446  

        0.071

Total  1

Step-by-step explanation:

The relative frequency is computed by dividing the individual frequencies to the sum of frequencies.

sum of frequencies=12+15+25+4=56

Class     Relative Frequency

10-20       12/56=0.214

20-30      15/56=0.268

30-40      25/56=0.446

40-50      4/56=0.071

Total         12/56+15/56+25/56+4/56=56/56=1

29).  The 'six' is the same as (6 x 5) = 30 fifths.
So  six and three fifths = (30 + 3) fifths  =  thirty-three fifths.

30).  The 'eight' is the same as (8 x 6) = 48 sixths.
So  eight and five sixths = (48 + 5) fifths=  fifty-three sixths.

31).  Twenty-seven of the thirds are the same as  (27/9)  = 3 .
That leaves a remainder of 2 thirds.
So  twenty-nine thirds are the same as  3 and 2/3 .

32).  Thirty-two of the fourths are the same as  (32/4) = 8 .
That leaves a remainder of one fourth.
So  thirty-three fourths are the same as  4 and 1/4 .

A line that is perpendicular to y=-2/7x+9y and that passes through the point (4, -6)
IrinaK [193]
--------------------------------------------------
Find Slope :
--------------------------------------------------
y = -2/7x + 9
Slope = -2/7
Perpendicular slope= 7/2

--------------------------------------------------
Find y - intercept :
--------------------------------------------------
y = mx + b
y = 7/2 x + b
At (4, -6)
-6 = 7/2 (4) + b
-6 = 14 + b
b = -6 - 14
b = -20

--------------------------------------------------
Form equation :
--------------------------------------------------
y = mx + b
y = 7/2 x - 20
2y = 7x - 40

--------------------------------------------------
Answer: 2y = 7x - 40
--------------------------------------------------
