Answer:
Mean= 242.5 pounds
Median= 236 pounds
Mode= 208 and 278 pounds
Range=117 pounds
Mid-range= 58.5 pounds
B. The results are likely to be representative because a championship team is most likely representative of the entire league.
Step-by-step explanation:
278 303 186 292 276 205 208 236 278 198 208
Arranged in ascending order is
186 198 205 208 208 236 276 278 278 292 303
Mean = (186 +198+ 205+ 208 +208 +236 + 276+ 278 +278+ 292 +303)/11
Mean =2668/11
Mean= 242.5 pounds
Median = the middle number
Median= 236 pounds
Mode = highest occuring number(s)
Mode= 208 and 278 pounds
Range= highest number- smallest number
Range=303-186
Range=117 pounds
Mid-range= range/2
Mid-range= 117/2
Mid-range= 58.5 pounds
25 pounds because 20 pounds is 100% so 10 is 50% and 5mis 25%
Option C:
x < –2 (or) x ≥ 4
Solution:
To find which compound inequality is represented by the graph:
Note:
If the circle is filled, then use ≤ or ≥.
If the circle is not filled, then use < or >.
In the given graph,
–5, –4, –3 are lesser than –2 and 5 is greater than 4.
–2 > x (or) 4 ≤ x
i.e x < –2 (or) x ≥ 4
Here the circle is not filled for –2, so use strictly less than symbol.
The circle is filled for 4, so use greater than or equal to symbol.
Option C is the correct answer.
Hence x < –2 (or) x ≥ 4 is the compound inequality represented by the graph.
