Answer: -12.5
Step-by-step explanation:
x(2y-3) and x=2.5 and y=-1
so you fix in the figures so it will turn to
2.5(-2-3)
so then you open the brackets with 2.5
-5-7.5
Answer: -12.5
Answer: Find the measures of an exterior angle and an interior angle given the number of sides of each regular polygon. Round to the nearest tenth, if necessary. 24 b 15, 345 24, 156 7.5, 172.5 15, 165
Step-by-step explanation: sum, S, of the measure of the interior angles of a polygon with n sides is: ... The sum of the interior angles of a 24 -gon is 3960. ... angles of a polygon is (n−2)⋅180 , where n is the number of sides. ... Each exterior angle measures 36024=15 . ... The sum of the 24 interior angles is then 24⋅165=3960 .
Answer: a) 0.6141
b) 0.9772
Step-by-step explanation:
Given : Mean : 
Standard deviation : 
The formula for z -score :

a) Sample size = 1
For x= 63 in. ,

The p-value = 

Thus, the probability is approximately = 0.6141
b) Sample size = 47
For x= 63 ,

The p-value = 

Thus , the probability that they have a mean height less than 63 in =0.9772.
Answer 8,050
Reason the absolute value of 8000 is 8000. The absolute value of negative 50 is 50. 8000+ 50= 8,050
