Answer:

31%

Step-by-step explanation:

To determine the probability of obtaining 3 or any number in a roll, we divide the number of outcomes with the sample space.

           probability of 3 :    n = 6/64 = 3/32 = 0.09375

           probability of 4 :    n = 14/64 = 7/32 = 0.21875

Since, we use the conjuction "or", we therefore add up these probabilities. 

                     n = 5/16 or 0.3125

Hope this Helps

fiasKO [112]

Answer:

  • x = 30°
  • RS = 30°, SR = TU = 120°, UR = 90°
  • ∠P = 45°
  • ∠UTS = 60°

Step-by-step explanation:

(a) If RS = x, then the sum of arcs around the circle is ...

  x + 4x +4x +3x = 360°

  12x = 360°

  x = 30°

__

(b) Based on the given ratios, the arc measures are computed from x. For example, ST = TU = 4x = 4(30°) = 120°

  • RS = 30°
  • ST = 120°
  • TU = 120°
  • UR = 90°

__

(c) Angle P is half the difference of arcs TU and RS:

  ∠P = (TU -RS)/2 = (120° -30°)/2

  ∠P = 45°

__

(d) Inscribed angle UTS is half the measure of the arc it intercepts. Arc RU has the measure (30° +90°) = 120°, so the measure of UTS is ...

  ∠UTS = 120°/2 = 60°

Find two mixed numbers so that the sum is seven wholes and two eights and the difference is two wholes and four eigths
Alex_Xolod [135]

Answer:

Step-by-step explanation:

x + y = 7 + 2/8 = 58/8

x - y = 2 + 4/8 = 20/8

Add the equations together

2x = 78/8

x = 39/8

y = x - 20/8 = 19/8

x = 39/8 = 4⅞

y = 19/8 = 2⅜
