Write the equation of the line perpendicular to 2x - 6y = 12 that passes through the point (-3,0).

slope = 1/3

perpendicular slope = -3

y = mx + b

0 = -3(-3) + b

A coach divided his team into two groups of equal size.
DerKrebs [107]

Applying the percentages, and considering that 70% of the first group drinks at least 2 glasses of water a day, it is found that 0.725 = 72.5% of the team drinks at least 2 glasses of water a day.

The team is divided into two equal groups, hence, each represents 50%.

The <em>percentages </em>associated with drinking at least 2 glasses of water a day is:

  • 70% of 50%(first group)
  • 75% of 50%(second group)

Hence, applying the weighed percentage, the total percentage is:

T = 0.7(0.5) + 0.75(0.5) = 0.725

0.725 = 72.5% of the team drinks at least 2 glasses of water a day.
