Which steps can be used in order to determine the solution to -1.3+4.6x=0.3+4x? a). subtract 1.3 from both sides of the equation, add 4x to both sides of the equation, then divide by the coefficient of x. b). subtract 1.3 from both sides of the equation, subtract 4.6x to both sides of the equation, then divide by the coefficient of x. c). add 1.3 to both sides of the equation, subtract 4.6x to both sides of the equation, then divide by the coefficient of x. d). add 1.3 to both sides of the equation, subtract 4x to both sides of the equation, then divide by the coefficient of x.

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;
