A friend asks you to check their homework. Did they make any mistakes? What advice would you give to your friend to avoid any possible errors? 1. 4(12s - 3d) + 5(6s + 8d)
2. 48s - 3d + 30s + 8d      by distributive property
3. (48s + 30s) + (-3d + 8d)       by associative property
4. 78s + 5d        by combining like terms

8121 because

130,000 divided by 16 is 8121

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;

step-by-step explanation:

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.
