Answer:</h2>
The statement that best describes the experimental probability of getting heads is:
It is 10% higher than the theoretical probability.
<h2>
Step-by-step explanation:</h2>
We know that the theoretical probability of getting head is: 0.5
and the theoretical probability of getting tail is: 0.5
Also, the results of experiments are:
Heads Tails
90 60
This means that the experimental probability of getting head is: 90/150=3/5=0.6
and the experimental probability of getting tail is: 60/150=2/5=0.4
Hence, the experimental and theoretical probability of getting head is not same or equal.
Also, the experimental probability of getting head is more than the theoretical probability of getting head and the percent increase is calculated as:
Start by completing the square.
x^2-8x-3y^2+12y=-16
x^2-8x+16-3(y^2-4y+4)=-16+16-12=-12
Notice the addition of those constants allows us to factor these expressions and because we did it to both sides it’s completely legit.
(x-4)^2-3(y-2)^2=-12
However, it seems we get a negative radius, which is not allowed. I think you entered the problem incorrectly.
Answer:
Step-by-step explanation:
By applying Pythagoras theorem in ΔEGD,
ED² = EG² + GD²
y² = 5² + 2²
y = √29
y = 5.39
By applying cosine rule in ΔBCD,
cos(28.3)° = 
x = 19cos(28.3)
x = 16.73"
Area of ABCDE = Area of trapezoid ABDE + Area of triangle BCD
= 
= 85 + 75.28
= 160.28 square inch
Perimeter of ABCDE = AB + BC + CD + DE + AE
= 5.39 + 16.73 + 9 + 5.39 + 15
= 51.51"
