When a number is touching parentheses is means you should multiply.

Based on your question you should multiply 3 on the numbers inside the parentheses.

3 × 5 = 15

3 × 2 = 6

Then combine the answers,

15 + 6 = 21

Your answer would be 21

Hope this helped! :D

There is 60% chance that it will rain today. If it rains, the probability of watching a movie is 0.5. But, if it does not rain t
agasfer [191]

Applying the given probabilities, it is found that there is a 0.42 = 42% probability of watching a movie today.

These following <em>probabilities </em>involve a movie being watched today:

  • 0.5 of 0.6(if it rains today).
  • 0.3 of 1 - 0.6 = 0.4(if it does not rain today).

Hence, adding them:

p = 0.5(0.6) + 0.3(0.4) = 0.3 + 0.12 = 0.42

0.42 = 42% probability of watching a movie today.

Answer:

170

Step-by-step explanation:

The angle 42x+1 is the inscribed angle of Arc WX. This means Arc WX is twice of 42x+1.

wx = 2(42x + 1)

We can add up that and the other arcs to 360.

2(42x + 1) + 29x - 1 + 65x + 3

84x + 2 + 29x - 1 + 65x + 3 = 360

178x + 4 = 360

178x = 356

x = 2

Plug in 2 for WX.

84(2) + 2 = 170
