Answer:
the answer to your questions are below
Step-by-step explanation:
1.-
x = 3x - 60
3x - x = 60
2x = 60
x = 30
A = 30
2.-
- x + 26 = 2x - 10
2x + x = 26 + 10
3x = 36
x = 36/3
x = 12
D = 2(12) - 10
D = 24 - 10
D = 14
3.-
5x + 10 = 7x - 12
7x - 5x = 10 + 12
2x = 22
x = 22/2
x = 11
4.- 4x + 7 = 5(x - 4)
4x + 7 = 5x - 20
5x - 4x = 7 + 20
x = 27
5.- 6(x - 2) = 3x + 30
6x - 12 = 3x + 30
6x - 3x = 30 + 12
3x = 42
x = 14
DHG = 6(14 - 2)
DHG = 6(12)
DHG = 72
With random sample of 50 and probability of adult American agrees is 75%, then the sampling distribution of the sample proportion is the Binomial distribution, with n=50 and p=0.75
We use Binomial distribution when the number of observation is fixed, each observation is fixed and each observation represents an outcome of "success" and "failure". In above case, the number of observation is 50 and the outcome of success is 0.75
Answer:
x = 12
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
8 + 6x is an exterior angle of the triangle, thus
8 + 6x = 30 + 4x + 2 = 4x + 32 ( subtract 4x from both sides )
8 + 2x = 32 ( subtract 8 from both sides )
2x = 24 ( divide both sides by 2 )
x = 12
