The central angle and the length of arc are related by the formula:
Length of arc = (θ/360) * 2πr
Where θ = Central angle.
If the central angle is one quarter of the entire circle, the length of arc would also be one quarter of the entire circumference of the circle.
The individual that is correct is Natasha. This is because the answer can be gotten using Natasha's method
The given equation is 
<u><em>Solving the equation using </em></u><u><em>Natasha's</em></u><u><em> method </em></u>
the fist step is to multiply by 2
x + 24 = - 6
The second step is to combine and add similar terms
x = -24 - 6
x = -30
<u><em /></u>
<u><em>Second method of solving the equation</em></u>
The equation the friends are trying to solve is 
The first step is to combine similar terms
= - 8 - 2
The second step is to add similar terms together
= - 10
The third step is to multiply both sides of the equation by 3
x = (-10 x 3)
x = -30

Answer:
Follows are the solution to the given question:
Step-by-step explanation:
In point a:
The confidence interval will not provide convincing proof that only the two population prolongations differentiate because a 99 percent confidence interval for both the difference throughout the true promotion around -0.020 and 0.120 is included 0.
In point b:
This confidence interval gives strong evidence also that two population proportions were identical because there is a confusion interval of 99 percent between -0.020 and 0.120 for the difference in the true percentage of the population that say "Yes".
