Step-by-step explanation:

From the equation y=2x+8, we can assume that y equals the total cost and that 8 equals the base price of a cheese pizza. The problem also tells us that x is the number of toppings and 2 is the number modifying that variable (remember that 2 is also the slope). So 2 must be the cost of each topping because it is being multiplied by the number of toppings. So 1 topping would be 2*1, an extra 2 dollars, and 4 toppings would be 2*4, so an extra 8 dollars for toppings.

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;
