Answer:
47.3
Step-by-step explanation:
as shown above ,this question can be solved using trigonometry and hence we get the perimeter to be 47.3
To solve for the margin of error:
margin of error = critical value x standard error
To compute for the critical value:
1. compute alpha: α= 1 - (confidence level/100) = 1 - .99 = 0.01
2. Find the critical probability: p = 1 - α/2 = 1 - (0.01/2) = 0.995
3. Look for the z score at the z table, in this case it is 2.58. This is your critical value.
To compute for the standard error, the formula is:
standard error = standard deviation (σ) divided by √n = 1.6 / √420 = 0.0781
Now plug in the following in the formula:
margin of error: 2.58 * 0.0781 = 0.2014 or 0.20
The answer is letter C.
Answer:
15.7
Step-by-step explanation:
d = 2r
d = 8 thus r = 4
area (kelly) = 4 x4 x 
= 16
area (paige) = 3 x 3 x = 9
difference = 16 - 9 = 5 = 15.7
Answer:
Option 2
Step-by-step explanation:
Measurement of angles doesn't change after shapes are translated, this is one of the properties of translated angles.
