Triangle xyz is reflected over its hypotenuse to create a kite.

what is the approximate distance from y to y’? round to the nearest tenth.

a. 4.6 units
b. 5.4 units
c. 8.0 units
d. 9.2 units (dumb answers will be reported)

The angle between line XZ and line XY is given by:

Then, the height from vertex Y to horizontal line XZ is:

Then, the distance from Y to Y 'is given by:

the approximate distance from Y to Y 'is:

D. 9.2 units

b

step-by-step explanation:

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;
