The LED which would glow brightest is LED C with the greatest current and voltage
The LED which would be the most dim is LED B with low voltage and consequently low current.
<h3>How to determine the current</h3>The formula for finding current
I = V/R
Where v = voltage
R = resistance
A. V = 12V
R = 4. 7 + 15 = 19. 7 kΩ = 19700 Ω in series
×
A
B. V = 9V
R = 4. 7 + 1 = 4. 7 kΩ = 4700Ω in series

C. V= 12V
1/R = =

It is important to note that the brightness of a bulb depends on both current and voltage depending on whether the bulb it is in parallel or series.
The LED which would glow brightest is LED C with the greatest current and voltage
The LED which would be the most dim is LED B with low voltage and consequently low current.

Answer:
A.) 132.3 mm Hg
B.) 49 years old
Step-by-step explanation:
P = blood pressure
y = age in years
A.) Solution
To find: P
Given: y = 48
P = 0.006 x 48 x 48 - 0.01 x 48 + 119
P = 0.006 x 2,304 - 0.48 + 119
P = 13.824 - 0.48 + 119
P = 132.344 ⇒ 132.3
B.) Solution
To find: y
Given: P = 132.92
