Answer:
She paid $1,275.00.
Step-by-step explanation:
I'm assuming you meant $1,500, so I'll be using that.
You can figure this out by subtracting 15% of 1,500 from 1,500.
15% of 1,500 is 225.
1500-225=1275
Therefore, 15% off of $1,500 is $1,275.
Answer:
The combined standard deviation is 1.58114.
Step-by-step explanation:
The formula to compute the combined standard deviations of two different data sets is:

Here
is the combined mean given by:

It is provided that the sample size is same for both the data sets, i.e.
Compute the combined mean as follows:

Compute the combined standard deviation as follows:

Thus, the combined standard deviation is 1.58114.
Answer:
x =12
Step-by-step explanation:
1/2x + 3 = 2/3x + 1
1/2 = 3/6 ; 2/3 = 4/6
3 - 1 = 4/6x - 3/6x
2 = 1/6x
x = 12
