Wich one I can help maybe
They're probably asking for the total payment, so add $720 to the initial amount, $2,000, so the answer is $2,720.
It's 3/4 because the only factor you can divide them both with is 2 and 3 and 4 have noi factors to divide by to make it lower.
To find if it’s a right-angled triangle, we will have to use Pythagorean Theorem:
a² + b² = c²
1st triangle: (yes, it is)
40 ² + 30 ² = 50 ²
1600 + 900 = 2500
2500 = 2500
2nd triangle: (No)
15 ² + 21 ² = 26 ²
666 = 676
3rd triangle: (Yes)
1.8 ² + 8 ² = 8.2 ²
67.24 = 67.24
4th triangle: (No)
85 ² + 85 ² = 121 ²
14450 = 14641
Answer:
0.109
Step-by-step explanation:
Probability is expressed by the number of desirable outcomes over the total outcomes. The total outcomes would be 2^8 because there are two possibilities in each flip, and using the fundamental counting principle, you get 2^8 total outcomes. Next, to find the amount of situations where you only flip two tails, you use 8 choose 2 because we are looking for the amount of ways you can choose 2 out of the 8 to be tails. 8 choose 2 is the same as:
8! / (6! x 2!) - 28
So, the probability is:
28 / 2^8 or 28/256
As a decimal, this is: 0.109375
And rounded to the nearest thousandth it's 0.109
