A rectangle is considered a special case of a parallelogram because: Aparallelogram is a quadrilateral with 2 pairs of opposite, equal and parallel sides. Arectangle is a quadrilateral with 2 pairs of opposite, equal and parallel sides BUT ALSO forms right angles between adjacent sides.
A. 69 degrees
exterior angles should equal 360 degrees so just add 131+160= 291 , 360-291= 69 degrees
or u can find it by finding the interior angle degrees by using supplementary angles. 180-131= 49 , 180-160= 20, 20+49=69, 180-69= 111 so the missing exterior angle corresponding interior is 111 and u can use supplementary angles to find the exterior. 180-111= 69 degrees
Answer:
The probability is 0.1312
Step-by-step explanation:
Here, let us set up a binomial system
From the question, 54% ride a bike
Let p = people that rides a bike
54% = 54/100 = 0.54
p = 0.54
q = 1 - p = 1 -0.54 = 0.46 ( 46% do not ride bikes)
Now, for the binomial system, we have
P(X = 15) = 30 C 15 • p^15•q^15
We have;
30 C 15 * 0.54^15 * 0.46^15
= 0.131200268998
The probability is 0.1312
5-12 is the answer for 520 5-06
