<u>Answer:</u>
2. The correct answer option is 25%.
3. The experimental probability is 3% greater than the theoretical probability.
<u>Step-by-step explanation:</u>
2. We are given that a number cube is rolled 20 times out of which 5 times it lands on the number 2.
We are to find the experimental probability of getting the number 2.
P (2) = 
= 25%
3. The theoretical Outcomes are: HH HT TH TT
So theoretical probability of getting HH = 
= 25%
Total number of outcomes = 
= 100
So experimental probability of getting HH = 
= 28%
Therefore, the experimental probability is 3% greater than the theoretical probability.
Answer: J=12
Explanation: To make this equation easier to solve, you can make everything a whole number (a.k.a. Remove the fractions). To do so, you can multiply everything in this equation by the Least Common Multiple (LCM) of all the denominators, which is 12. The equation now becomes:
-4=3J-40
Then, solve it using normal algebra:
-4=3J-40
36=3J
J=12
Much easier, right?!

Answer:84 degrees
Step-by-step explanation:
so if a triangle is 180 degrees in total you need to find how much you need to equal that so you add 59+37=96 degrees so then you will subtract 180-96=84 degrees

Answer:
11/4 or , 2 3/4
Step-by-step explanation:
I don't like math so I am not going to call it fun, but these problems are super easy for me, so it almost IS fun.
4/4 = 2/2 because they are both wholes.
2/4 = 1/2 because they are both halves.
Now, if we split one of the numbers down, we will get one of these.
6 1/4
6 x 4 because there are 6 wholes...= 24
then 24 plus 1 because there is still one fourth...=25
25/4
Now, 3 1/2 pounds.
Lets change it to fourths. 3 2/4
Now, 3 x 4, 12, then 12 plus 2 equals 14/4
Now compare your numbers.
Answer:
These results, 7 and 9, have a product of 63, as stated.
Step-by-step explanation:
Represent the first odd number by x and the first consecutive odd number by x + 2. Then the product of these two numbers is x(x + 2) and it equals 63.
Solve for x. Perform the indicated multiplication, obtaining
x^2 + 2x - 63 = 0
Solve this by factoring: (x + 9)(x - 7) = 0
Then x could be either -9 or +7. If we let x = 7 then the first consecutive odd number is 7 + 2, or 9. These results, 7 and 9, have a product of 63, as stated.
