Wendy had 35 tickets for games at a carnival. she used 1/5 of the tickets to play the ball-toss game. she then used 1/2 of the remaining tickets to play the ring-toss game , in witch she won 5 more tickets. how many tickets did wendy

19 tickets remainng

Step-by-step explanation:

35 x 1/5 = 7

35-7 = 28 tickets

28 x 1/2 = 14 (used half so would have 14 left)

14 + 5 = 19

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;
