A bag of Jolly Ranchers contains 300 pieces of which 28% are blue. How many are not blue?

216

Step-by-step explanation:

300 x .28 = 84

300 - 84 = 216

216

Step-by-step explanation:

300 -> 100% (Total candies)

___ -> 72% (NOT Blue candies)

___ -> 28% (Blue candies)

Next:

28% = 0.28

300 x 0.28 = 84

84 = Number of candies that are Blue

300 -> 100% (Total candies)

___ -> 72% (NOT Blue candies)

84   -> 28% (Blue candies)

Now:

300 - 84 = 216

300 -> 100% (Total candies)

216 -> 72% (NOT Blue candies)

84 -> 28% (blue candies)

216 equals the number of candies that are NOT Blue

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
