Answer: I think that the answers are
a = 1
b = 10
For this you would do 4000 x 0.2 which equals 800.
800 acres were not plowed.
Thanks :)
Answer: y = 4x + 1
Step-by-step explanation:
1. Make the equation its parallel to in slope intercept form by subtacting 4x to get -y = -4x+ 2 then dividing both sides by -1 to get y = 4x -2
When dealing with parallel lines thier slopes are ALWAYS the same, so the equation we are making should have the slope of 4.
2. Plug in the corrordinates x and y values and the slope into the point-slope form equation to find the y intercept
(y - (-3)) = 4(x - (-1))
3. Solve for y in slope intercept form:
y + 3 = 4x + 4 ----> y = 4x + 1
Answer:
z score Perry 
z score Alice 
Alice had better year in comparison with Perry.
Step-by-step explanation:
Consider the provided information.
One year Perry had the lowest ERA of any male pitcher at his school, with an ERA of 3.02. For the males, the mean ERA was 4.206 and the standard deviation was 0.846.
To find z score use the formula.
Here μ=4.206 and σ=0.846
Alice had the lowest ERA of any female pitcher at the school with an ERA of 3.16. For the females, the mean ERA was 4.519 and the standard deviation was 0.789.
Find the z score
where μ=4.519 and σ=0.789
The Perry had an ERA with a z-score is –1.402. The Alice had an ERA with a z-score is –1.722.
It is clear that the z-score value for Perry is greater than the z-score value for Alice. This indicates that Alice had better year in comparison with Perry.

What is the future value of an ordinary?
An ordinary annuity is the one where the monthly deposit occurs at the end of each month rather than at the beginning of the months such its future value based on 5.5% annual interest rate can be determined thus:
FV=PMT*(1+r)^N-1/r
FV=balance in dollars and cents in Yolanda's account at the end of 4 years=unknown
PMT=monthly deposit=$100
r=monthly interest rate=5.5%/12=0.00458333333333333
N=number of monthly deposits in 4 years=4*12=48
FV=$100*(1+0.00458333333333333)^48-1/0.00458333333333333
FV=$5,355.29
