We calculate a 95% confidence interval for the true mean of problems answered correctly by 12th graders on the SAT to be [27.2, 73.6). Interpret the confidence interval
Fill in the blanks:

We are (blanks) confident that the( blank )of plausible( blank ) values from( blank) contains 12th graders true (blank )to (blank )of correctly answered questions on the SAT

m∠vru = 80°

m∠urw = 15°

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
