Answer:
260
Step-by-step explanation:
There are a few ways to solve this, but an easy to understand one is that 39=15%, therefore 13=5%, as it is taking 1/3 of each number. Then to get to 100% we would need to multiply 13=5% by 20 to get 260=100%
Answer:
1) sum of all convex polygons' EXTERIOR ANGLES IS ALWAYS 360 DEGREES. If it is a triangle or even if it is a 25- gon.
2) if the polygon is regular then this means all of the sides are equal and all of the angles are equal to each other.
for example: Find the measure of an exterior angle of a REGULAR HEXAGON. so a regular hexagon has 6 sides all the same length and 6 exterior angles all the same measures. so to find the measure of 1 exterior angle you do 360 degrees /6 = 60 degrees. so an exterior angle of a regular hexagon is 60 degrees.
The answer is 78

Sample 1 :1.5
Sample 2:-2.5
sample 3:5.5
Answer:
Step-by-step explanation:
Given that:
The sample size = 150
The sample mean = 70.69
The standard deviation = 29.60
The sample mean is equal to the point estimate of the population = 70.69
At 99% confidence interval level is:
∝ = 1 - 0.99
∝ = 0.01
The critical value:
The Margin of error = 
= 2.58 × 2.4168
≅ 6.235
At 99% confidence interval; the estimate of the population mean lies within the interval:
= 
= 70.69 - 6.235 < μ < 70.69 + 6.235
= 64.455 < μ < 76.925
= (64.455
, 76.925
)
