Keegan and Annie are working on an experiment in the science lab Their mixture contains ingredients that weight 5.22 grams 5.7 grams and 7.43 grams Keegan calculates the combined weight to be 18.22 grams and Annie calculated it to be 13.22 grams

78.59 is the mean

step-by-step explanation:

1/3 + 1/5 = 8/15.

step-by-step explanation:

hope it

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
