In your notebook, set up the following subtraction in a vertical format and select the correct answer. Reduce 7y + 2y2 - 7 by 3 - 4y.

-2 y2 + 11 y - 10
2 y2 - 11 y + 10
-2 y2 - 11 y + 10
2 y2 + 11 y - 10

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;

what

the correct answers i think are b. and d.

give me brainliest if it is correct!
