Answer:
Step-by-step explanation:
There are 15 numbers on a list, and the smallest number is changed from 12.9 to 1.29.
a. Is it possible to determine by how much the mean changes? If so, by how much does it change?
Yes. The total would decrease by 11.61. so mean would decrease by 11.61/15 =0.774
b. Is it possible to determine the value of the mean after the change? If so, what is the value?
No. new men would be old mean - 0.774
c. Is it possible to determine by how much the median changes? If so, by how much does it changes?
Though the smallest number is changed the position does not change.
Hence median will not change.
d. Is it possible to determine by how much the standard deviation changes? If so, by how much does it change?
The original variance would be average of square of deviations of the old mean.
Answer:
1.02n
Step-by-step explanation:
A simplified version of this expression would be the following
1.02n
This is basically adding the n variables together. We do this by adding a 1 to the number being multiplied to n. This would basically add the 2% on top of what the original pay per hour is. We can prove that these two expressions are the same by substituting n for 10 in both expressions and solving them.
1.02n
1.02 * 10 = 10.2
n + 0.02n
10 + 0.02*10
10 + 0.2 = 10.2
Answer:
1. 4x + 6
2. -15x + 11
5. -x + 4
6. -4x + 7
9. 5x - 2
12. x + 16
Step-by-step explanation:
Remove the parenthesis for each one so everything's out in the open. Next, you group like terms. The numbers with variables on one side, and the other numbers on the other side. For example:
x + 3x - 2 + 8
Then, you combine like terms:
4x + 6
That's mostly how you do each one.
