Answer:
step 2
Step-by-step explanation:
1) so in step 2 Becky make 4/5-5/4=0
this is wrong, as we have to make common denominators first:
16/20-25/20=-9/20
so now, we got -9/20
-9/20+7=
2) make common denominators again
-9/20+140/20=131/20
this is the right answer Hope this helps!
(a.)
Mean= sum / n
Mean= (123+116+122+110+175+126+125+111+118+117) / 10
Mean=1243 / 10
Mean= 124.3
Median:
Rearranged the data in order first
110,111,116,117,118,122,123,125,126,175
118 and 122 are at the middle
Median=1/2(n1 + n2)
Median=1/2(118+122)
Median=240/2
Median= 120
(b) 175 is the larger than the others value and larger than the mean, so it is the substantial difference between the mean and the highest value (175).
