Answers and Step-by-step explanations:
Let's look at the first row:
cost = _______ + _______ * (monthly payment)
The first blank should be the "down payment" because this is the initial, constant value that is paid. The second blank should be the "number of months" because this way, when multiplied by the actual amount each payment is (monthly payment), then we get the total amount paid during those months.
So, we have:
cost = (down payment) + (number of months) * (monthly payment)
Now for the second row, we just plug in numbers and variables:
335 = 50 + 6 * p
Finally, we can solve for p:
335 = 50 + 6p
6p = 285
p = $47.50

Answer:
Mean = 0.2(100) = 20
Variance = 0.2×0.8×100 = 16
Standard deviation = 4
Yes, np > 5 & nq > 5
Answer:
x = 9
Step-by-step explanation:
since the terms are in AP then there is a common difference between consecutive terms, that is
a₂ - a₁ = a₃ - a₂ ( substitute values )
x - 7 = 11 - x ( add x to both sides )
2x - 7 = 11 ( add 7 to both sides )
2x = 18 ( divide both sides by 2 )
x = 9
