From the question we are told that:
Sample size
Generally Number of class (K) is Mathematically given as
Therefore
Generally with class interval of k
Class Width is mathematically given as
The complete Table is attached below
2)
The complete Image of the Histogram is attached below
Answer:
20 units squared
Step-by-step explanation:
Area = base times height
Area = 5 x 4 = 20
Answer:
0, because 5 divided by 8 is 0.625. 0.625 is not a whole number. 5/8 = 0.625
4x + 5y = 31
5y = -4x + 31
y = -4/5x + 31/5...the slope here is -4/5. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we need is 5/4 (see how I flipped the slope and changed the sign)
y = mx + b
slope(m) = 5/4
(-1,-7)...x = -1 and y = -7
now we sub and find b, the y int
-7 = 5/4(-1) + b
-7 = -5/4 + b
-7 + 5/4 = b
-28/4 + 5/4 = b
- 23/4 = b
so ur perpendicular line will be : y = 5/4x - 23/4
Probably the 2nd last question but please elaborate by what you mean by the question
