Which of these correctly rearranges the terms in this polynomial so like terms are next to each other

4 - 6x + 2x^2 - 4x + 6x^2

a. -2x^2 + 6x^2 - 6x - 4x + 4 + 2

b. 6x^2 - 2x^2 + 6x - 4x - 4 + 2

c. 6x^2 - 6x -2x^2 - 4x + 4 + 2

d. 6x^2 - 6x - 4x + 4 + 2x^2 + 2

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;

tried on you are knowing that we can't leave the picture in the graph ok no problem now you need to send it in the question group
