Given:
The sample size n=25
Probability of population is 65 or older is 10.5%.
This date follows the binomial distribution,
To find the probability that at most 2 are 65 or older,
Answer: Probability is 0.504 .
Well the line is called a ray because because the left of the endpoint is a dot and it doesn't go anywhere. So your answer is a ray.
hope that helped
since the polygon has 8 chambers the angle of one chamber = 360/8 = 45°
so the angle WOP = 45°
now drawing a imaginary line which seperates the triangleWOP into half
so the angle of imaginary line is 45/2 = 22.5
sin(theta) = opp/hyp
since WP (opp) is unknown. take as x
sin(22.5) = x/44
0.383×4 = x
x = 1.532 (app) = 1.5 cm
perimeter = 1.5 × 8
= 12 cm
area of triangle WOP = 2×1/2 ×bh = bh
= 4×1.5
= 6 cm²
so the area of regular polygon = 8× area of a triangle
= 48 cm²
Considering that the mean of the normal distribution is the same as the median, the median is of 88%.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
For the normal distribution, the median is the same of the mean, that is, the median is of 88%.
