Answer:
10%
Step-by-step explanation:
The computation of the percentage of bulbs that switched on incandescent is as follows;
Let us assume the incandescent be I
And, the fluorescent be F
Now the equation is
0.4I + 0.9F = 0.8 (I+F)
0.41I + 0.9F = 0.8I + 0.8F
So here
0.4I = 0.1F
Now the percentage would be for incandescent in the case of switched on is
= 0.4I ÷ 0.8(I+F) × 100
= 0.1F ÷ 1F
= 10%

Answer:
77,936
Step-by-step explanation:
To find the mean, add up all the numbers, then divide by that amount of numbers. So, 12,274 + 12,368 + 12,544 + 12760 + 12,911 + 13,162 + 13,419 = 89,438/ 7 = 77,936.
