During a snowstorm, snow falls at a constant rate and is recorded by a meteorologist. The data is plotted on the graph below. image 4d350c56ce5e40a9bd78c427ec45784c

Which equation models the relationship between the number of hours, x, of the snowstorm, and the number of inches of snow, y, on the ground?
y=3x+3
y=13x+3
y=3x+18
y=13x+18

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;

investment b is an ordinary annuity with $3,909.64 in the account after one year.
