If the exterior angle of a regular polygon equals 120 degrees what is the shape is the polygon

Answers

It is a triangle, because the sum of the exterior angles is always 360. We need to find a natural number n, such that 360/n=120. Of course n is 3 which means there are 3 angles. Three angles means 3 sides so it is a triangle! Or triangular.

The standard deviation of a sample taken from population A is 17.6 for a sample of 25. The standard deviation of a sample taken from population B is 21.2 for a sample of 30. The standard deviation of the sample mean difference is?

Answers

The answer is 5.5

The standard deviation (sd or σ) of the sample mean difference is:
sd = √(sd₁²/n₁ + sd₂²/n₂)

For the population A:
sd₁ = 17.6
n₁ = 25

For the population B:
sd₂ = 21.2
n₂ = 30

Hence:
sd = √(sd₁²/n₁ + sd₂²/n₂)
= √(17.6²/20 + 21.2²/30)
= √(309.76/20 + 449.44/30)
= √(15.49 + 14.98)
= √(30.47)
= 5.5

Answers

Put up a graph or a chart, and suddenly everything you're saying makes sense! Graphs or charts help people understand data quickly. Whether you want to make a comparison, show a relationship, or highlight a trend, they help your audience "see" what you are talking about.

What is the standard form for 25x²+4y²+50x-24y-39=0

Answers

25x² + 4y² + 50x - 24y - 39 = 0
25x² + 50x + 4y² - 24y - 39 = 0
25x² + 50x - 39 = 0   4y² - 24y - 39 = 0
x = -b + √b² - 4ac y= -b + √b² - 4ac
      2a 2a
x = -50 + √(-50)² - 4(25)(-39)     y = -(-24) + √-(-24)² - 4(4)(-39)
   2(25) 2(4)
x = -50 + √2500 + 3900 y = 24 + √-576 + 624

x = -50 + √6400 y = 24 + √48
      50    8
x = -50 + 80 y = 24 + √16 × 3
   50 8
x = -50 + 80 y = 24 + √16 √3
   50   8
x= -50 + 80    y = 24 + 4 √3
   50 8
x = -50 + 80                                        y = 24 + 4 √3
   50    8
x = -50 + 80   x = -50 - 80 y = 24 + 4 √3   y = 24 - 4 √3
      50 50 8     8
x = 30     x = -130     y = 28 √3     y = 20 √3

(x, y) = (3, 26 √3) (x, y) = (-13, 20 √3 )
