The table shows the battery life of four different mobile phones. mobile phone battery life phone battery life (hours) a 20 b 25 c 10 d 18 if 6.45% of the battery life of each mobile phone is used in a day by atypical user, for which mobile phone is 1.6125 hours of battery life in a day?

The answer is phone B

I took the quiz! :)

the correct answer is option c.   3

step-by-step explanation:

points to remember

equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,

slope m = (y₂ - y₁)/(x₂ - x₁)

from the figure we can see a line with two coordinates given

to find the slope of given line

here   (x₁, y₁)   = (-1, -1 ) and (x₂, y₂) = (1, 5)

slope m = (y₂ - y₁)/(x₂ - x₁)

  = (5 - -1)/(1 - -1)

  = (5 + 1)/(1 + 1)

  = 6/2 = 3

therefore the correct answer is option c.   3

5 x 14?
