Answer:
It increases the mean value of the prizes
Step-by-step explanation:
If you order the numbers from the lowest to the highest, the median is the number placed in the middle of the ordered list. In this case, there are values repeated many times (there are 100 values, $1 is repeated 44 times and $5 is repeated 25 times, so $5 is the mean), then the presence of a high value with only one presence doesn't modify this median.
On the other hand, the mean is always affected but all data set, given that $100 is the highest value, the mean will increase.
Answer:
1. x = 86
2. x = 31
3. x = 64
4. x = 29
Step-by-step explanation:
1. 2x + 8 = 180
-8 -8
2x = 180 (divide both sides by 2 to get x by itself)
2. 3x - 3 = 90
+ 3 +3
3x = 93 (divide both sides by 3 to get x by itself. you divide because 3x is multiplying and you have to do the reverse operation)
3. 2x -5 + x - 7 = 180 (you combine like-terms)
3x -12 = 180
+12 +12
3x = 192 (you divide by 3 on both sides)
4. x + 1 + x + 4 + x - 2 = 90 (combine like-terms)
3x + 3 = 90
-3 -3
3x = 87 (divide both sides by 3)
This is the answer and the steps for doing it
The first four terms of the sequence are 3 , 6 , 12 , 24
Step-by-step explanation:
We need to find the first four terms of the sequence
where to find them do that
- Substitute n by 2 in the rule to find
- Substitute n by 3 in the rule to find
- Substitute n by 4 in the rule to find
∵
- Substitute n by 2 to find the 2nd term
∴
∴
∵
∴
∴
- Substitute n by 3 to find the 3rd term
∴
∴
∵
∴
∴
- Substitute n by 4 to find the 4th term
∴
∴
∵
∴
∴
The first four terms of the sequence are 3 , 6 , 12 , 24

77(7) = 539, the total points of all her tests
539 - 18 + 81 = correct total points = 602
602/7 = 86 which is the new average
