Let the second score = x
⇒ second score = x
<span>the first is 14 points more than the second
</span>⇒ first score = x + 14
<span>the sum of the first two is 6 more than twice the third
</span>⇒ third score = 1/2 (x + x + 14 - 6) = x + 4
<span>The sum of a student's three score is 246
</span>⇒ x + (x + 14) + (x + 4) = 246
<span>
Solve x:
</span>x + x + 14 + x + 4 = 246
3x + 18 = 246
3x = 228
x = 76
second score = x = 76
first score = x + 14 = 76 + 14 = 90
Answer: 90
Answer:
Very certain it is C
Step-by-step explanation:
There are no points on the graph line itself so I cannot really confirm this but i am 70% sure
Its 400 ..... hope that helps :)
Your answer is 160 i had this on a test hope this helps
The outlier is 20
it affect the mean because
1)32 +40+34+ 31 +20+ 36 +40+31=264
2) 264 divided by 8= 33
so it gives you an odd number
