Vanessa found a less expensive “motivator” for her robot business. The old “motivator” cost $4.00; the new motivator cost $3.65.
aliya0001 [1]
4.00 - 3.65 = 0.35....so she saves 35 cents on each motivator

with 220 motivators...
0.35(220) = $ 77 <== what she saves

A population of flies grows according to the function p(x) = 3(2)x, where x is measured in weeks. A local spider has set up shop
kifflom [539]
The answer is 14 flies 

1. Calculate the population of flies after 3 weeks without the spider: p(3)
2. Calculate the number of eaten flies by the spider after 3 weeks: s(3)
3. Subtract p(3) and s(3) to get  the population of flies after three weeks with the introduced spider.

1. Calculate the population of flies after 3 weeks without the spider:
     p(x) = 3(2)ˣ
     x = 3 (because it is the period of three weeks)
⇒  p(3) = 3 · 2³ = 3 · 8
     p(3) = 24

2. Calculate the number of eaten flies by the spider after 3 weeks:
      s(x) = 2x + 4
      x = 3 (because it is the period of three weeks)
⇒   s(3) = 2 · 3 + 4 = 6 + 4
      s(3) = 10

3. Subtract p(3) and s(3) to get  the population of flies after three weeks with the introduced spider:
    p(3) - s(3) = 24 - 10 = 14
Therefore, there are 14 flies after three weeks with the introduced spider.

1,8,5,4,1,8,5,4<br>Mean:<br>Median:<br>Mode:
Lynna [10]

Answer:

1. Mean = 55.8

Median = 23

Mode = None

2. Mean = 2.1

Median = 1.4

Mode 0.5

3. Mean = 4.5

Median = 4.5

Mode = 1,4, 5, 8

4. Mean 68

Median 58

Mode = 0

Step-by-step explanation:

Mean = 17 + 25 + 23 + 200 + 14 / 5 = 279/5 = 55.8

Median= Because its odd you put them in order 17, 14, 23, 25, 200 = 23 because it is the middle number. Mode = None

2. Mean = 0.5 + 1.4 + 3.0 + 7.0 + 0.5 +1.8 + 0.5 = 14.7 = 14.7/7 = 2.1

Median = because it is odd you put them in order 0.5, 0.5, 0.5, 1.4, 1.8, 3.0, 7.0 = 1.4 The mode is 0.5 because it repeats three times

3. Mean = 1 + 8 + 5 + 4 + 1 + 8 + 5 + 4 = 36/8 =4.5

Median = Because its even you divide by the two middle numbers = 1, 1, 4,4, 5, 5 , 8 , 8 = 4+5 = 9/2 = 4.5 Mode = 1, 4, 5, and 8 are the numbers that are repeated most often.

Mean = 0+78+99+58+65+0+47+38+227 = 68 Median, Because there is an odd number you get the odd number from the middle. 0, 0, 38, 47, 58, 65, 78, 99, 227 = 58 Mode = 0 because it repeats more often.
