The table of the number of dolphins is used to illustrate probability

The probability that a dolphin group is partaking in travel is 0.2063

<h3>How to determine the probability</h3>

From the table, we have:

  • The total number of dolphin group = 189
  • The total number of dolphin group that partake in travel = 39

So, the probability that a dolphin group is partaking in travel is calculated as:

p = 39/189

Divide

p = 0.2063

Hence, the probability that a dolphin group is partaking in travel is 0.2063

Which triangle side lengths form a right triangle? Choose all that apply. 5, 6, 7 6, 8, 14 8, 15, 17 10, 12, 15 15, 20, 25 16, 1
yuradex [85]

Answer:

C. 8, 15, 17

E. 15, 20, 25

Step-by-step explanation:

You need to take the 2 smaller numbers as in 8 and 15 square it, so 8x8= 64 and 15x15= 225 and then add 64+225= 289 and 17x17=289 so 289=289 ✔

Again square 15 and 20, 15x15=225 and 20x20=400 add them 225+400=625

and 25x25=625 so 625=625 ✔

Hope this helped and good luck!

Use the Pythagorean Theorem to find the distance of the missing side. (I’m sorry I need help with the whole thing)
Maurinko [17]

Answer:

1: 5.83

2: 4.12

3: 3.61

4: 5

5: 6.32

6: 5.10

Step-by-step explanation:

The Pythagorean theorem is a^2 + b^2 = c^2

For all of these you can count the number of blocks over to find two sides of the triangle.

For example: the first one has two sides, one is 3 units, the other is 5. To find the missing angle you square 3 and 5, then add that together. That is equal to 34. 34 = c^2. To get the c by itself, you then take the square root of 34. So the missing side (c) is equal to 5.83.
