Answer:
2.0491 watt per meter square
Step-by-step explanation:
We are given the following in the question:
The intensity of light is given by:

where W is the wattage of the light bulb and r is the distance to the light bulb.
We have to evaluate the intensity of bulb with W = 100 watts and r = 2 meters.
Putting values, we get,

Thus, the intensity of light bulb is 2.0491 watt per meter square.
This is the concept of statistics. The correct answer is:
There are twice as many participants in the 0-19 age group than in the 60-79 age group. This is because:
Number of participants in the age group 0-19 is 40 participants
Number of participants in the age group 60-79 is 20 participants.
From the above we see that the age group 0-19 is double the number of age group 60-79 years old.
Therefore our answer is option C
Answer:
Step-by-step explanation:
9x - 1 / 2 + 9/2 x = 0.128886 (43)
2 / 5x - 1b = 4/3 - 1 - 1 = 2x (4)
= x1 + 24 - 3/4 + 8
9/3 - 1 x = /3
Approximate solutions are
X subset 2 is approximately equal to -2.72
X subset 1 is approximately equal to -0.28
