Given that the owner of a local nightclub has recently surveyed a random sample of n = 250 customers of the club.
(Right tailed test)
Sample size =
Sample mean = 30.45
Mean difference =
Sample std dev s = 5
Sample std error =
Test statistic = Mean diff/std error =
Since population std deviation is not know we use t test
p value =
Answer: m∠CAD = 81°
Step-by-step explanation: <u>Diagonal</u> is a line that unites opposite sides.
ABCD is a prallelogram. One property of diagonal in a parallelogram is it separates the parallelogram in 2 congruent triangles.
The figure below shows ABCD with its diagonals.
Since diagonal divides a parallelogram in 2 congruent triangles, it means the internal angles are also congruent. So
m∠BAC = m∠CAD
4x + 5 = 5x - 14
x = 19
Then, m∠CAD is
m∠CAD = 5(19) - 14
m∠CAD = 81
The angle m∠CAD is 81°.
