Answer:
Mean = 2
Standard deviation = 1.356
Step-by-step explanation:
We are given;
Probability of taxpayers that make mistakes when filling out forms: p = 0.08
Sample size; n = 25
In binomial distribution;
Means is;
μ = np
Thus;
μ = 25 × 0.08
μ = 2
Formula for standard deviation here is;
σ = √(np(1 - p))
σ = √(25 × 0.08(1 - 0.08))
σ = 1.356
Answer:
Step-by-step explanation:
Remember that the sum of the interior angles of a triangle always equal 180. Therefore:
Let's subtract 102 from both sides. This yields:
Now, notice the that both ∠1 and ∠Y have exactly one arc mark.
Arc-marks denote congruence. Therefore, ∠1 and ∠Y are congruent to each other. In other words:
So, we can substitute ∠Y for ∠1 for our equation. This yields:
Combine like terms:
Divide both sides by 2. So, the measure of our angle is:
And we're done!
Y=21n(x2+2)y=21n(x2+2)
21n(x2+2)(y-1)=0
n=0, x=i/2-i/2, y=1
