<span>Experimental probability is defined as the
ratio of the number of times an event occurs to the total number of
trials the activity is performed
In this case the number that the event occurred is 8 and the number of trials is 50, so the ratio is 8/50 = 4/25.
Then the answer is option B: 4/25

Answer:
Length= 30 in
Width= 10 in
Step-by-step explanation:
Let the width of the rectangle be x in.
Length of rectangle
= 3 (width)
= 3x
Perimeter of rectangle= 2(length) +2(width)
80= 2(3x) +2(x)
80= 6x +2x
8x= 80 <em>(</em><em>simplify</em><em>)</em>
x= 80 ÷8 <em>(</em><em>÷</em><em>8</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
x= 10
Thus width of rectangle= 10 in
Length of rectangle
= 3(10)
= 30 in
You first simplify
tan(x) = cos(x)/sin(x) and cot(x) = sin(x)/cos(x)
Then you plug that in and then you simplify even more
A pair of angles, which are either adjacent or non-adjacent, whose sum is 90 degrees, is classified and known as Complementary Angles. Complementary Angles are made from adjacent or non-adjacent angles, when added to together, their sum is equal to 90 degrees.
