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.
Answer:
D
Step-by-step explanation:

OK so each block is 3cm tall and 3.5cm wide (because 2 are 7cm wide)
so to measure the perimeter count all the side values for example:
the 5 squares at the bottom which measure 3.5cm each adds up to a total of 17.5cm then if you add the top 2 flat sides that's another 2, 3.5cm which adds up to 7cm. 17.5cm + 7cm = 24.5cm then their are 3 walls on each side measuring 3cm each so 3cm * 6 = 18
24.5cm + 18cm = 42.5cm (I think this is correct)
Answer:
52 is the multiple of 13
Step-by-step explanation:
3x+3=156
3x=153
x=52
Assuming that you mean 100cm in length, I think I know the answer, but message me if I’m wrong so that I can correct myself!!!
Volume is L • W • H where L is length, W is width, and H is height.
To find the volume you have to multiply all the dimensions, so 100 * 30 * 12 = 36,000, and since its 3 dimensional we use cm^3 which is centimetres cubed.
