Answer:
(D) Pie chart
Step-by-step explanation:
The most appropriate method to represent the resulting data is the pie chart. This is because, in this sample, the variables are few and of nominal type.
Of the rest of the options, the only other that could be used is the histogram, since it can represent nominal variables with their corresponding frequency. The rest of the options have other uses not appropriate for this type of sample.
5/7x + 1/7 = 63
7(5/7x) + 7(1/7) = 7(63)
5/x + 1 = 441
5/x = 440
5 = 440x
5/440 = x
1/88 = x
Answer:
see explanation
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
To obtain this form use the method of completing the square on both the x and y terms
rearranging
x² + 6x + y² - 4y = 12
x² + 2(3)x + 9 + y² + 2(- 2)y + 4 = 12 + 9 + 4
(x + 3)² + (y - 2)² = 25 ← in standard form
with centre = (- 3, 2) and r =
= 5
Answer: 0.42
60-18= 42
42/100=0.42
