Answer:
53.13
Step-by-step explanation:
mJKL = sin-1(9/15) = 36.9 deg
mKJL = = 36.9 deg ...base angles of isosceles triangle JKL
mJLK = 180 - 36.9 - 36.9 = 106.26 deg
mJPK = mJLK/2 = 106.29/2 = 53.1 deg......half of central angle
Answer:
9 inches
Step-by-step explanation:
The population is within 6 standard deviations of the mean with a confidence of 99.7 percent, 3 above and 3 below
The standard deviation of the sample mean is equal to the population standard deviation divided by the square root of the sample size
population standard deviation = 36
sample size = 144
standard deviation of the sample mean = 36/ sqrt(144)
=36/12
=3
The margin of error is the number of standard deviations above the mean * the standard deviations
margin of error = 3 * 3
= 9 inches
