Answer:
Step-by-step explanation:
Where x represents the previous year's salary, its amount this year is said to be ...
x + 2000
The equation is trying to reflect the fact that 7% of that is $3,290. The missing number is 2000:
0.07(x +2000) = 3290
__
Solving for x, we find ...
x = (3290/0.07) -2000 = 45000
Sandra's salary the previous year was $45,000.

Answer:
<h2>The mean is 26666.67 and the standard deviation is 372919430.33.</h2>
Step-by-step explanation:
The mean means the average of the numbers.
The mean will be .
The differences of the earnings from the mean are 1666.67, 26997.33, 33997.33.
Squaring the numbers we get, 2777788.89, 728855827.13, 1155818447.12.
We need to find the mean of the above numbers to get the standard deviation.
Thus, the standard deviation is .
Simple...
you have: for every 96 miles you consume 4 gallons of gas..
What you're trying to find is how much gas you consume per gallon.
96/4=24
This means for every gallon it's 24 miles. Unit Rate=24
Thus, your answer.
