Answer:

256 cm

Step-by-step explanation:

An octagon has eight sides, so just multiply the 32 cm side length by 8:

Perimeter = 8(32 cm) = 256 cm

Murljashka [212]

Answer:

broad sense heritability = 0.75

Step-by-step explanation:

Step 1: Variables

phenotypic variation (Vp)

genotype variation (Vg)

environment variation (Ve)

broad sense heritability (H)

Step 2: Formulas:

H = Vg / Vp

Vp = Vg + Ve

Vg = Vp - Ve

Step 3: Given data

Vp = 20

Ve = 5

Step 4: Computation

Vg = 20 - 5 = 15

H = 15 / 20

H = 0.75

Hope this helps!

25 Pts + Brainliest for the first correct answer.
WITCHER [35]

Answer:

25.  x=19

26.  16=x

27  28=x

28.  24=x

Step-by-step explanation:

25.  The two angles make a straight line  (180 degrees)

6x-17 + 3x+26 = 180

Combine like terms

9x +9 = 180

Subtract 9 from each side

9x+9-9=180-9

9x = 171

Divide by 9

9x/9 = 171/9

x=19


26.  These angles are corresponding angles and corresponding angles are equal if the lines are parallel

4x+20 = 6x-12

Subtract 4x from each side

4x-4x+20 = 6x-4x-12

20 =2x-12

Add 12 to each side

20+12 = 2x-12+12

32=2x

Divide by 2

32/2 = 2x/2

16=x


27  These are alternate interior angles and alternate interior angles are equal if the lines are parallel.

4x+30 = 6x-26

Subtract 4x from each side

4x-4x+30 = 6x-4x-26

30 = 2x-26

Add 26 to each side

30+26 =2x-26+26

56= 2x

Divide by 2

56/2 = 2x/2

28=x


28.  These are corresponding angles and corresponding angles are equal if the lines are parallel.

99=3x+27

Subtract 27 from each side

99-27 = 3x+27-27

72 = 3x

Divide by 3

72/3 = 3x/3

24=x

What is the difference between DEPENDENT and INDEPENDENT probability?
ira [324]

Answer:

an independant variable dosent depend on any thing and a dependant variable depends on

if you rode a paddle boat for 30 min it cost 10 dollars

the 30 min is the independant variable and the 10 dollars is the dependant variable bc if u wanted to ride for longer than 30min you will have to pay more money therefore the cost depends on the time and time is independent bc the dosent depend on anything
