PLEASE HELP . G’Koby is a running back for the Utopian football team. In the last game on the team's first possession of the ball, he ran for 20 yards on the first play, lost 15 yards on the second play but gained 25 yards on the third play. Where is the line of scrimmage (where is the ball now)?

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best
