Guys please which one is the right answer. I need help

The equation would be 8n + 11 = 3n + 26.

I'm gonna assume we're talking about  "n".

b) 8n+11=3n+26 (because they are corresponding angles)

n=3

Step-by-step explanation:

8n+11=3n+26    

simplifying:

8n-3n+11-11=3n-3n+26-11

5n=15

n=3

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;
