Gordon, June and Sushil share some sweets in the ratio 4:4:3. Gordon gets 11 more sweets than sushil. How many sweets altogether

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;

5 + 8 +7 + 4 + 0 +1 = 25

step-by-step explanation:

i honestly dont know

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
