Lacey is planning a beach vacation for next month. She compares the weather at two beaches during the
same month last year. At the first beach, it rained 5 out of 30 days. At the second beach, it rained 10% of
the days. Based on this experimental data, which beach has a better chance of being dry? Complete the
explanation. Round your answer to the nearest percent if necessary.
The second 7 beach has a better chance of being dry.
At the first beach, it rained about 75
% of the days.

answer: the answer is ann

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

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
