Just a test have fun with free points!

x = 0.666(Repeating)

Step-by-step explanation:

4x+1=5

Subtract 1 from both sides

4x=6

Divide both sides by 4

x = 0.666(Repeating)

4x+1=5

4x=5-1

4x=4

x=4/4

x=1

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;
