Answer:

m = -32

Step-by-step explanation:

Let x = days and y = box of cookies

So, we have:

(x_1,y_1) = (0,228) -- When she started

(x_2,y_2) = (4,100) --- After 4 days

Required

Determine the slope

The slope (m) is calculated using:

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{100 - 228}{4 - 0}

m = \frac{-128}{4}

m = -32

<em>The slope is -32</em>

The cost of a pound of nails increased from ​$2.17 to ​$2.52. What is the percent of increase to the nearest​ whole-number perce
Cloud [144]

Answer:

16%  is the percent of increase to the nearest​ whole-number percent.

Step-by-step explanation:

As the cost of a pound of nails increased from ​$2.17 to ​$2.52.

  • $2.52 - $2.17 = $0.35

so dividing the 0.35 by 2.17 would give us the percetange of increase

  • 0.35/2.17 = 0.16 which is 16%.

Therefore, 16%  is the percent of increase to the nearest​ whole-number percent.

Olive rolls a 5 on one number cube and then Lolly rolls a 1 on another number cube. Is this a set of independent or dependent ev
rjkz [21]
<h3>Answer:  independent </h3>

Reason:

Each cube doesn't affect the other one, which means that the probabilities are not altered. This is assuming that the cubes don't bump into each other when rolling on the table. So either there's enough space on the table, or they take turns one at a time.
