Answer:
-7/2 degrees per hour
Step-by-step explanation:
Divide the total change (-12 1/4 degrees) by the total time elapsed (3 1/2 hrs):
-49/4 degrees -49(2)
------------------------ = ------------- = -7/2 degrees per hour
7/2 hrs 4(7)
You add 9 to both sides to get:

Answer:
Sum of and is
Option B is correct answer.
Step-by-step explanation:
We need to find sum of and
Finding sum of and :
We know that
Replacing x^2-4
Now, taking LCM of (x+2)(x-2) and (x+2) we get (x+2)(x-2)
So, Sum of and is
Option B is correct answer.
Area of isosceles triangle is 7.8235
Height = base/2 x tan 41 = 2.61
Base length = 2 x ( side length of triangle) x cos 41
6= 2 x ( side length of triangle, assume it b ) x 0.754
6= 1.509 x b
b = 6/ 1.509
b= 3.975
Area = 1/2 b x h
= 1/2 x b^2 Sin square theta
= 7.8235
Given:
Ellen flipped a coin 80 times. The coin landed heads up 44 times and tails up 36 times.
To find:
The theoretical and experimental probabilities of the coin landing tails up and compare them.
Solution:
We know that, the coin landed either heads up or tails up. So, the theoretical probabilities of the coin landing tails up is
Ellen flipped a coin 80 times. The coin landed heads up 44 times and tails up 36 times.
Total = 80
Tails =36
The experimental probabilities of the coin landing tails up is
Therefore, the theoretical and experimental probabilities of the coin landing tails up are 0.5 and 0.45 respectively. The theoretical probability is greater than the experimental probability.
