The time (in minutes) required to learn the procedure for performing a certain task is uniformly distributed on the interval fro
PtichkaEL [24]

Answer:

a

 P( X >  46)  = 0.7 \  minute

b

\mu  = 42 \ minute

Step-by-step explanation:

From the question we are told that  

   The procedure for performing a certain task is uniformly distributed on the interval from( a =  32 )minutes to (b= 52) minutes

  Generally the cumulative distribution function for continuous uniform distribution is  

             F(x) =  \left \{ {{0 \ \ \ \ \  for  \  x \  x < a} \atop {\frac{x-a}{b-a} } \ \   for \  a \le x \ge b} \atop {1 \ \ \ \ \ \ \  for  \  x  >  b }\right.

Generally the probability that it takes more than 46 minutes to learn the procedure is mathematically represented as

          P( X >  46)  = F(46) = \frac{46 - 32}{52-32}

=>       P( X >  46)  = 0.7 \  minute

Generally the average time required to learn the procedure is mathematically represented as

        \mu =  \frac{a + b}{2}

=>     \mu  =  \frac{32 + 52}{2}

=>     \mu  = 42 \ minute

Plz I need help with geometry homework FIND THE ANGLES
Talja [164]

Answer:

  1. a = 36°
  2. b = 36°
  3. c = 72°
  4. d = 72°
  5. e = 108°
  6. f = 16°
  7. g = 74°
  8. h = 70°

Step-by-step explanation:

You are expected to know and make use of the following relations:

  • vertical angles are congruent
  • angles of a linear pair are supplementary
  • angles of a triangle sum to 180°
  • alternate interior angles are congruent (at parallel lines)
  • corresponding angles are congruent (at parallel lines)
  • acute angles of a right triangle are complementary
  • base angles of an isosceles triangle are congruent

__

For this problem, it isn't always easiest to work the questions in order. It is best to start with the angles easiest to find from those given.

  b and 144° are a linear pair, so b = 180° -144° = 36°

  a and b are alternate interior angles, so a = b = 36°

  2d and 144° are corresponding angles, so d = 144°/2 = 72°

  e is the apex angle of an isosceles triangle with base angles 36°, so is 180° -2(36°) = 108° = e

  f and 164° are a linear pair, so f = 180° -164° = 16°

  g and f are complementary, so g = 90° -16° = 74°

  g+h is a vertical angle with 144°, so is congruent to that. h = 144° -74° = 70°

  c is the base angle of an isosceles triangle with b as the vertex angle. That means c = (180° -36°)/2 = 72°
