Answer:
mmm, well, not much we can do per se, you'd need to use a calculator.
I'd like to point out you'd need a calculator that has regression features, namely something like a TI83 or TI83+ or higher.
That said, you can find online calculators with "quadratic regression" features, which is what this, all you do is enter the value pairs in it, to get the equation.
Step-by-step explanation:
Answer:
(x-2 )( x + 1) = (-2 - c)
Step-by-step explanation:
C= - 1 = -x
We cna either multiply x and c until we find HCM before imputing x value and c value that is unknown variable.
To find that we can say x = the average of 1000 + $800 = $900 and work out the difference between the two.
We can use a new variable for half that difference to ensure we add or subtract to find the value 1000 or -1000 again.
So that $1000 - $847 = $153 half this difference is 2/3y so that 4/3 = $153 and 1/3 = 33.333 as we are working with 3 numbers then 1/3 or 2/3 for example could show a debit;
Balance of each 1000 would look like
2/3y + x + c
= c + xy - y1/3
to show smaller amounts for the last 2 debits.
Answer:
x=12
Step-by-step explanation:
AB/FE=BC/EC
x/6= 5+5/5
x/6=10/5
x=6(2)
x=12

Answer:
Mean = 2
Standard deviation = 1.356
Step-by-step explanation:
We are given;
Probability of taxpayers that make mistakes when filling out forms: p = 0.08
Sample size; n = 25
In binomial distribution;
Means is;
μ = np
Thus;
μ = 25 × 0.08
μ = 2
Formula for standard deviation here is;
σ = √(np(1 - p))
σ = √(25 × 0.08(1 - 0.08))
σ = 1.356
