Cupcaking, a cupcake bakery, uses the equation below to determine the price of cupcakes, where y represents the total price in dollars and x represents the number of cupcakes purchased.
y=3/2x
cake me, another cupcake bakery, uses the table below to determine prices.
(x) (y)
2 3.50
3 5.25
4 7.00
6 10.50
katie bought one cupcake from cupcaking and sarah bought one cupcake from cake me.
which of the following are true?
a) katie is paying the smaller price of $1.50 per cupcake.
b)sarah is paying the smaller price of $1.25 per cupcake.
c) katie is paying $0.25 per cupcake more than sarah.
d)sarah is paying $0.25 per cupcake more than katie.
e)they are paying the same price per cupcake.
you can pick more then one : )

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

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;
