Which transformations could map triangle WXY onto triangle RST to show that they are similar? A. Reflect across line PQ, then dilate with a scale factor greater than 1. B. Rotate 180 degrees clockwise about point P, then dilate with a scale factor greater than 0 and less than 1. C. Reflect across line PQ, then dilate with a scale factor greater than 0 and less than 1. D. Rotate 90 degrees counterclockwise about point P, then dilate with a scale factor greater than 1.

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;

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
