Answer:
k = 31
Step-by-step explanation:
k - 6.2 = 24.8
+6.2 +6.2 (Add 6.2 to both sides to isolate the variable: k)
__________
k = 31
1.) 20,24,25,27,31,35,38
2.) Least value: 20 Greatest value: 38 Median: 27
3.) Lower Quartile: 24 Upper Quartile: 35
4.) Draw the first dot above 20, then a line connecting to the first line above 24, then another line above 27, then another line above the 35, then connect it to the dot that will be above 38. The lines above 24, 27,35 should make a box like the one shown at the beginning of your paper.
5.)61,63,65,68,69,70,72,74,78
6.) Least value: 61 Greatest value: 78 Median: 69 Lower quartile: 64 Upper quartile: 73
7.) Just like in number 4, plug these numbers in and create your box and whisker plot.
Answer:
Mₙ= 3*1.2⁽ⁿ⁻¹⁾
Step-by-step explanation:
week 1- 3 miles
week 2 - +20% ⇒ 3*1.2
week 3- +20% ⇒ 3*1.2*1.2
...
week n- +20% ⇒ 3*1.2⁽ⁿ⁻¹⁾
Mₙ= 3*1.2⁽ⁿ⁻¹⁾
Mₙ - miles on week n
Answer:
Step-by-step explanation:
<u>1. Cell phone usage</u>
Mon to Sun = 38, 62, 40, 10, 30, 55, 65
- Mean = (38+62+40+10+30+ 55 + 65)/7 = 43 minutes rounded
<u>2. Water bills</u>
Jan to Dec = $40 $42 $40 $38 $48 $50 $58 $62 $56 $46 $44 $44
- Mean = (40+42+40+38+48+50+58+62+56+46+44+44)/12 = $47 rounded
