Ameterorologist said that it rained during 20% of the past 60 days. on how many days did it not rain?

30 days will be my answer 60 / 2

It did not rain for 48 days

All you have to do to receive the answer is

.2 * 60 to get 12, it rained for 12 days

and then 60-12 to get 48, it did not rain for 48 days.  

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
