y= -2x + 12
Step-by-step explanation:
Thanks for letting me answer your question! If you have any more questions feel free to ask me! Have a nice day and please consider making me Brainliest!
Per cent means out of 100. 47/100
slope = y2-y1 over x2-x1
-1 - 4= -5
-8-0 - -8
so you get -5/-8
negative divided by negative = positive
slope = 5/8
First i dont know what is the meaning of the mmc098-2.jpg, mmc098-3.jpg and <span>mmc098-4.jpg. but base from what you had written is a set of equation where you solve the values of each variables. but unfortunately i cant solved it because of what you have written there. please give me the correct equation so i can solve it</span>
Answer:
(a) 95% confidence interval for the percent of all adults who want to lose weight is (48%, 54%) that is between 48% and 54%
(b) to say that we have 95% confidence in this interval means that there is 95% chance that the true percentage of all adults who wants to lose weight falls in this interval.
Step-by-step explanation:
The question is missing, complete question is below:
A Gallup Poll found that 51% of the people in its sample said "yes" when asked, "Would you like to lose weight?" Gallup announced: "With 95% confidence for results based on the total sample of national adults, one can say that the margin of sampling error is ± 3%."
(a) What is the 95% confidence interval for the percent of all adults who want to lose weight?
(b) What does it mean to say that we have 95% confidence in this interval?
Confidence Interval can be calculated using p±ME where
- p is the sample proportion of national adults who want to lose weight (51%)
- ME is the margin of sampling error (± 3%)
