Answer:
Step-by-step explanation:
The central angle of the segment is 60 degrees. Line CD is the same length as the radius and there are 3 sides with the same length. The triangle so formed is equilateral and the apex angle is 60 degrees which is the central angle.
The measure of arc CD is 60 degrees.

A random sample of 300 circuits generated 13 defectives. a. Use the data to test

Versus

Use α = 0.05. Find the P-value for the test
Answer:
The p-value is
Step-by-step explanation:
From the question we are told that
The sample size is n = 300
The number of defective circuits is k = 13
Generally the sample proportion of defective circuits is mathematically represented as

=> 
=> 
Generally the standard Error is mathematically represented as

=> 
=> 
Generally the test statistics is mathematically represented as

=> 
=> 
From the z table the area under the normal curve to the left corresponding to -0.5317 is

Generally the p-value is mathematically represented as

=> 
=>
38.1 seconds I believe simply divide 4m/s into 152.4 m and you will have 38.1 seconds
Answer:
t+4, t≠8
Step-by-step explanation:

The value of t must not be one that makes the denominator zero, hence must not be 8.
Answer: 2,215,000
Step-by-step explanation:
Given: The quadratic function
models the population of a city where x represents the number of years since 2005.
To Find: population of the city in 2010
We need to put x= 2010-2005 = 5

Hence, the estimated population of the city in 201 = 2215 thousands or 2,215,000 .
