Research seems to indicate that the optimum group size for problem solving is _____ members. Select one: a. 2 b. 15 c. 5 d. 25
Daniel [21]

Answer:

Correct answer is (c). 5

Step-by-step explanation:

It is important to note that solving problem requires techniques and intelligent people most especially when problem are complex or hard in nature. It is therefore important to ensure the numbers of problem solving experts should not be undersized than required to avoid over burden them and should not be too large to avoid conflict in their individual resolutions. Hence, most scientific reports state that problem solving experts should be within 3 to 5 members and as for this question, the optimum is 5 members.

Consider kite WXYZ.
kondaur [170]

Answer:

  • a = 8; b = 40

Step-by-step explanation:

<em>See attached</em>

<h3>Given </h3>

<u>Kite WXYZ with:</u>

  • XY = 3a - 5
  • YZ = a + 11
  • ∠W = 50°
  • ∠X = 3b
  • ∠Y = 70°
<h3>To find </h3>
  • Values of a and b
<h3>Solution</h3>

<u>Since XY and YZ are congruent sides, XY = YZ</u>

  • 3a - 5 = a + 11
  • 3a - a = 11 + 5
  • 2a = 16
  • a = 8

<u>The angles Z and X are equal and the sum of 4 angles is 360°, therefore:</u>

  • 3b + 3b + 50° + 70° = 360°
  • 6b + 120° = 360°
  • 6b = 240°
  • b = 40°

<u>Correct option is the last one </u>

  • a = 8; b = 40°
