Answer/Step-by-step explanation:

1. <ABC and <BCD are alternate interior angles. Alternate interior angles are equal, therefore, since m<ABC = 38°, then m<BCD = 38°

2. m<ECF = m<BCD (corresponding angles)

m<ECF = 38° (substitution)

3. m<DCF + m<ECF = 180° (linear pair)

m<DCF + 38° = 180° (substitution)

m<DCF = 180° - 38° (Subtraction property of equality)

m<DCF = 142°

find the ordered pairs for the x- and y-intercepts of the equation 3x - 2y = 18 and select the appropriate option below.
Vladimir79 [104]

Answer:

Step-by-step explanation:

3x - 2y = 18

x -int

3x - 2(0) = 18

3x = 18

x = 6

(6,0)

3(0) - 2y = 18

-2y = 18

y = -9

(0, -9)

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.

Explain how you can use division to simplify a complex fraction.
PolarNik [594]
Reduce the final answer if needed (or reduce when you multiply).  A mixed number should be converted to an improper fraction (heavier on top) before simplifying. Change the numerator and denominator to single fractions<span> by creating a common denominator</span>

Can transformations always be applied to shapes, even if they're not in a plane?
Tatiana [17]

A translation is a transformation of the plane in which a a plane figure slides along a straight line, and changes its position without turning. Each point moves the same distance and in the same direction. Hence all points subjected to the same translation undergo the same displacement.
