B. Stratified random sample is the correct answer
Answer:
B. the variability around the regression line.
Step-by-step explanation:
The standard errors represents the distance (how sparse) the observed values fall from the regression line.
Standard errors for regression are measures of the spread of variables around the average (regression line)
The standard error is dependent on the standard deviation of the observations and the reliability of the test.
When the test is perfectly reliable, the standard error is zero and when unreliable, it is equal to the standard deviation of the observations.
Answer:
The answer is 15.
Step-by-step explanation:
To find the percentage of something, you have to convert the percent to a decimal. 30 % as a decimal would be o.3. You would then multiply 0.3 by 50 which in turn, give you
15 points:)
Answer:
(2x-4)-(6-8x)
2x-4-6+8x
2x-10+8x
10x-10
Step-by-step explanation:
The question's asking the difference between 2 binomial polynomials.
1. To subtract them, you must use the distributive property to distribute the minus sign on the terms in the second polynomial.
2. Combine like terms. -4-6=-10, 2x+8x=10
<u>Answer is 10x-10</u>
