A bag contains 7 pieces of paper numbered 1 to 7. P(2)=. Is this an experimental or theoretical probability and why?
Lera25 [3.4K]

Answer:

theoretical probability

Step-by-step explanation:

This is theoretical probability.  The 7 pieces of paper each bear one number from {1, 2, ... , 6, 7}.  There is only one piece of paper marked 7.  So the probability of drawing a 2 is  1/7.

Divide 1.20m in the ratio 2:3:4 in a clear way
tatuchka [14]
2:3:4 gives 9 equal parts.
1.20 divided by 9 is 0.133.

2 * 0.133 would be 0.266m
3 * 0.133 would be 0.399m
4 * 0.133 would be 0.533m

To check this calculate 0.533 + 0.399 + 0.266 would be 1.198m (close enough)

Think carefully about the angle relationship the following represents.
lisov135 [29]

Answer:

See below ↓↓↓

Step-by-step explanation:

<u>Subquestion #1</u>

  • These angles form a linear pair
  • They are supplementary, and add up to 180°
  • 2x + 48 = 180
  • 2x = 132
  • <u>x = 66</u>

<u></u>

<u>Subquestion #2</u>

  • These angles are complementary, and add up to 90°
  • 35 + 4x + 7 = 90
  • 4x + 42 = 90
  • 4x = 48
  • <u>x = 12</u>

<u></u>

<u>Subquestion #3</u>

  • As in #1, they are a linear pair, and are supplementary
  • 3x + 54 = 180
  • 3x = 126
  • <u>x = 42</u>
