Describe the effect an increase in i, the interest rate applied to the present value, has on the monthly payment P in the formul

VARVARA [1.3K]

Answer:

B. An increase in i, the interest rate, will create an increase in P, the monthly payment.

Step-by-step explanation:

We have the formula for the monthly payment as,

$P=\frac{i \times PV}{1-(1+i)^{-n} }$ ,

where P = monthly payment, i = rate of interest, PV = present value and n = time period.

Now, as i increase we get that (1+i) increases and so $(1+i)^{n}$ increases.

This gives us that, $\frac{1}{(1+i)^{n} }$ decreases and so $1-\frac{1}{(1+i)^{n}}$ decreases

Therefore, $\frac{1}{1-(1+i)^{-n} }$ increases.

So, we get that as i increases , the value of P will increase.

Hence, option B is correct.

Suppose that E and F are two events and that N (E and F) = 260 and N(E) = 630. What is P(F|E)?

Sveta_85 [38]

Answer: 0.4127

Step-by-step explanation:

The probability formula to find p(F/E):

p(F/E)= N(E n F) / N(E)

p(F/E)= 260 / 630

p(F/E) = 0.4127

I have no idea how to do this please help

$\begin{gathered} a)slope\colon7 \\ b)y-intercept\colon-6 \end{gathered}$

1) As we can see this is a Linear Equation written in the Slope-intercept form:

$y=mx+b$

Note that "m" stands for the slope of the line, i.e. the measure of how steep a line is.

In the given equation, we can state that the slope is always accompanying the "x" therefore, the slope is m= 7

2) In addition to this, the y-intercept also called the Linear Coefficient is given by the letter"b" and represents the y-coordinate that the graph intercepts. Thus the y-intercept is -6

So we can state the following as the answers:

$\begin{gathered} a)slope\colon7 \\ b)y-intercept\colon-6 \end{gathered}$

And that is the answer
