Consider this population data set:4, 6, 7, 11, 12, 18, 26, 23, 14, 31, 22, and 12. The values 11, 31, 22, and 12 constitute a ra

Answer:
3.5
Step-by-step explanation:
Find the Mean of the Population Data Set
4 + 6 + 7 + 11 + 12 + 18 + 26 + 23 + 14 + 31 + 22 + 12 = 186
186 ÷ 12 = 15.5
Find the Mean of the Sample Data Set
11 + 31 + 22 + 12 = 76
76 ÷ 4 = 19
Subtract
19 - 15.5 = 3.5
Answer: <em>The sample mean is more than the population mean by 3.5</em>
Answer:
2
Step-by-step explanation:
(1-5)/(-3+1) = -4/-2 = 2
Answer:
9:15 or 3:5
Step-by-step explanation:
A ratio can compare a part of a whole to a whole.
In this case, our whole is the total number of shots attempted: 15.
The basketball player successfully made 9 of the attempts. 9 is our other number in this ratio.
Put these values in a ration.
part:whole
9:15
Notice that 9 and 15 can be simplified by dividing both numbers by 3.
3:5
This is your simplified ratio.
Hope this helps!
Hey there!
2^4=2x2x2x2
2*2=4
4*2=8
8*2=65
It equals 64.
Hope this helps! Let me know if you have any questions:)
