Answer:

  • C = 4: dependent system
  • C ≠ 4; independent, consistent system with solution (0, -2)

Step-by-step explanation:

If you divide the first equation by 2, you get ...

  4x -3y = 6

If C=4, the second equation would be identical to this, giving a dependent system of equations with an infinite number of solutions.

If you want a system of equations with one solution, the value of C must be anything except 4. (That system will have the solution (x, y) = (0, -2).)

ella [17]

The most improbable simulation for this coin is the heading when a coin is tossed 20 times will be 15.

<h3>What is probability?</h3>

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

A coin is biased to display heads 75% of the time.

It is tossed 20 times, and the outcomes are recorded.

Then the probability of getting heads when a coin is tossed 20 times. Then we have

\rm P = 0.75 \times 20 = 15

More about the probability link is given below.

What is angle DFE? 119 42 19 78
Liula [17]

Answer:

∠DFE=119°

Step-by-step explanation:

step 1

Find the measure of angle BFD

we know that

The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.

so

∠BFD=(1/2)[arc BD+arc CE]

substitute the given values

∠BFD=(1/2)[38°+84°]

∠BFD=61°

step 2

Find the measure of angle DFE

we know that

∠BFD+∠DFE=180° -----> linear pair (supplementary angles)

substitute

61°+∠DFE=180°

∠DFE=180°-61°=119°
