What is the Radius of a circle if a 16 unit chord is 6 units from the center of the circle
velikii [3]

Answer:

radius = 10 units

Step-by-step explanation:

using the Pythagorean theorem:

height of triangle = 6 units

base of triangle = 16/2 = 8 units

radius² = 6² + 8² = 36 + 64 = 100

radius = √100 = 10 units

Use the given degree of confidence and sample data to construct a confidence interval for the population proportion p. n = 195,
Semenov [28]
Given:
n = 195, sample size.
x = 162, successes in the sample

The proportion is
p = x/n = 162/195 = 0.8308

n* p = 195*0.8308 = 162
n*(1-p) = 195*(1 - 0.8308) = 33
If n*p >= 10, and n*(1-p) >= 10, then the sample proportions will have a normal distribution. This condition is satisfied.

The proportion mean is
μ = 0.8308
The proportion standard deviation is
\sigma =  \sqrt{ \frac{p(1-p)}{n} }  = \sqrt{ \frac{0.8308(1-0.8308)}{195} } =0.0269

σ/√n = 0.0269/√195 = 0.00192

At the 95% confidence level, the interval for the population proportion is
(μ - 1.96(σ/√n), μ + 1.96(σ/√n))
= (0.8308 - 1.96*0.00192, 0.8308 + 1.96*0.00192)
= (0.827, 0.8345)

Answer: The 95% confidence interval is (0.827, 0.835)
