Answer:
1. False
2. False
3. False
4. False
5. False
Step-by-step explanation:
1. Having an exponent of 0 and 1 is totally different as 0 power leads the answer to 1 whereas 1 leads the answer to the same as base.
2. Add all the exponents which doesn't adds to 2.
3. If the base is same the exponents add, not multiply.
4. Not it gets the answer 1.66 which is not equal 1/36.
5. Doesn't have the equivalent experssion.
Answer:
11/19 chance
OR
roughly 57% chance.
Step-by-step explanation:
If we add our marbles, we have a total of 19 marbles to pick from. 11 of those marbles are green. This means we have a 11/19 chance of picking two green marbles.
If you want to find the percentage then do this:
We know that we have a 11/19 chance. To find the percentage, we would need to turn the fraction into a decimal first.
11÷19≈0.579
To turn a decimal into a percentage, we would need to multiply the decimal by 10 (move the decimal two spaces to the right.)
That would give us 57.9%.
So, you have, approximately, a 57% chance of picking two green marbles.

Answer: The total number of ways are 792 ways.
Explanation:
The total number of spots available is 7.
The total number of eligible candidate is 12.
To find the number of combinations we have a combination formula.
Where n is total number of of objects and r is the number of selected objects.
Since we have to select 7 spots from 12 candidates, therefore the total number of ways is calculated as shown below,
Therefore, the total number of ways are 792 ways.
Answer: x = 15
Step-by-step explanation:
The formula for calculating the sum of the interior angles of a regular polygon is: (n - 2) × 180°. Where n is number of sides.
sum of angles = (n - 2) × 180
sum of angles = (7 - 2) × 180
sum of angles = 5 × 180
sum of angles = 900°
Now to find the value of x, we have to set each of the interior angles, added up, equal to 900°:
7x + 1 + 10x + 6x + 7 + 10x - 9 + 9x + 4 + 8x + 10 + 9x + 2 = 900
Combine like terms:
(7x + 10x + 6x + 10x + 9x + 8x + 9x) + (1 + 7 - 9 + 4 + 10 + 2) = 900
59x + 15 = 900
59x + 15 - 15 = 900 - 15 subtract 15 from both sides
59x = 885
59x/59 = 885/59 divide by 59 on both sides
x = 15
