Submit Answer
O Quadratic
O Exponential

  a)  Linear

Step-by-step explanation:

The x-values all change by 1 from one line to the next.

The y-values all change by 3 from one line to the next.

When the ratio of y-changes to x-changes is a constant, the function is linear.

y -5 = (-1/4)(x + 8)

step-by-step explanation:

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;
