Five light bulbs that are either on or off are lined up in a row. A certain code uses different combinations of lights turned on
Paraphin [41]

Answer:

10

Step-by-step explanation:

The number of different ways that 2 lights can be chosen from 5 is ₅C₂.  Use a calculator or find the value manually:

₅C₂ = 5! / (2! (5−2)!)

₅C₂ = 5! / (2! 3!)

₅C₂ = 5×4×3×2×1 / (2×1 × 3×2×1)

₅C₂ = 5×4 / 2

₅C₂ = 10

5/6 + 3j = -2/3 I need to find the value of j
weeeeeb [17]

5/6 + 3j = -2/3

Multiply all terms by 3.

5/2 = 3j - 2

Multiply all terms by 2.

5 = 6j - 4

Add 4 to both sides.

9 = 6j

Divide both sides by 6.

j = 1.5
