You share a packet of 48 jelly beans with you sister with a ratio of 5:3 how many jelly beans will you get?

30:18

Step-by-step explanation:

you get 30, sister gets 18.

add the parts (5+3) which equals 8

divide 48 by 8

which is 6

times 6 by both 5 and 8

therefore, (5*6):(3*8)

30:18

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;

.95
