The image of a point is B'(-4, 11). A 180° clockwise rotation was performed to get this image. What were the coordinates of the pre-image? (4, -11) (11, 4) (-11, -4) (4, 11)

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

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;

ratio is 2 : 9

the answer is three

13.5 : 3
