Answer: the answer is approximately 21
Step-by-step explanation: multiply -3 times -5 you get 15. then 2 plus 4 you get 6. add 15 + 6 you get 21.
You would pull out a 4 then 2 “x’s” and then 2 “a’s” because that is all they have in common making the answer 4x^2a^2
Answer:
b. We are 95% confident that the proportion of coworkers who went on a vacation last year away from home for at least a week is between 50% and 66%.
Step-by-step explanation:
A confidence interval at the level of x% for a proportion being between a and b means that we are x% sure that the true proportion of the population is between a and b.
In this problem, we have that:
95% C.I is (0.5, 0.66)
Interpretation: 95% confident that the true proportion is between 0.5 and 0.66.
The correct answer is:
b. We are 95% confident that the proportion of coworkers who went on a vacation last year away from home for at least a week is between 50% and 66%.
Answer: if the y-intercept is 5, it's c. -3/4x + 5. Since it's ax+b a = slope b = y intercept
