Answer:
1) you're going to have to flip the coins (or fake numbers) for the experimental trials.
2) for the theoretical, there is 1/2 chance for heads or tails with each toss, so you'd expect that out of 10 tosses, 5 heads, 5 tails. out of 100 tosses- 50 heads, 50 tails.
When tossing 2 coins- 1/2×1/2 = 1/4 (25%) chance that 2 heads, 2 tails, or 1 heads & 1 tails. Deviation value comes from after you done your flipping and recorded your data. So if on 100 flips you actually got 50 and 50 (rarely us that exact ;), the deviation from the expected of 50/50 would be 0.00. If however you flipped 100 heads or 100 tails (impossible), then the deviation value would be 1.00.
|(100-50)| ÷ 50 = 50÷50 = 1.00
So usually you may have data like: 47/53 or something a little off than 50/50, making deviation |(47-50)| ÷ 50 = 3÷50 = 0.06.
Now the number of flips is important for the outcome! So if a coin toss if 10 times had 4 heads, 6 tails, the deviation value would be:
|(4-5)| ÷ 5 = 1÷5 = 0.20
So increasing the # flips DECREASES the deviation value!!
Whether it's from 10 to 100, or from 100 to 200. Look at my example of how the 10-flip deviation of 0.20 decreased to 0.06 with 100-flip
The answer to “v” is 19.
10-6v=-104
10-6(19)=-104
10-114=-104
Answer: square root is a number that can be multiplied by itself to get that number in that radical aka checked half box.
Step-by-step explanation: square root of 18 is
Approx: ~4.2
Since that approx multiplied by itself is 19. Search up place values. Numbers after the decimals start from, tenths place, hundredths, thousands place and so on. This one asked for the tenths place. 0.2 the 2 is in the tenths place
Answer:
The main difference between a prism and a pyramid is that a prism has two bases, while the pyramid only has one.
The surface area of a prism is equal to the sum of the area of its bases and the lateral area
The total surface area of a regular pyramid is the sum of the areas of its lateral faces and its base
