0.077994
Step-by-step explanation:
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 = 
Because if it was even, then it would be divisble by 2 which makes it not prime

Answer:
20 yd²
Step-by-step explanation:
This problem is really easy once you break it down!
First, find the area of the triangle.

b = 5 + 3 = 8
h = 4 + 4 = 8


Now find the area of the square.



The last step is to subtract.
Area of triangle - area of rectangle =
32 - 12 = 20
20 yd²
Hope this helped! :)
