Hiro is creating a smaller scaled replica of a triangular canvas.
triangles abe and acd on a coordinate plane with point a at 1 comma 0, point c at 2 comma 3 and point d at 5 comma 0, point b is between points a and c and point e is between points a and d
which of the following expressions will him determine the length of segment ab?
a. ac equals ad times ab over ac
b. ab equals ae times ad over ab
c. ab = ad
d. ab = ac

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;

what is the your question?

answer: 1.06 km per sec

step-by-step explanation:

39.6 m=63.72 km

60 min in an hour so 63.72/60=1.06
