<u>Answer</u>

y = 5x +25


<u>Explanation</u>

To get the equation of a line, first get the slope of the line.

Slope = (change in y)/(change in x)

          = (60-30)/(7-1)

          = 30/6

            = 5

Now use one point in the line (4,45) and a general point (x,y).

Slope = (change in y)/(change in x)

    5 = (y - 45)/(x - 4)

    5(x - 4) = (y - 45)

  5x - 20 = y - 45

y = 5x -20 + 45

y = 5x + 25

The formula for the future value VV (in dollars) of an investment earning simple interest is V=p+prtV=p+prt, where pp (in dollar
wlad13 [49]
The future value of the investment in dollars s
V = p + prt
where 
p = principal, dollars
r = annual interest rate (in decimal form)
t = time, years

To determine p, write the formula as follows:
Factorize p out on the right side.
  V = p(1 + rt)
Divide each side b (1 + rt).
  \frac{V}{1+rt}=p

Answer:
p= \frac{V}{1+rt}

If A and B are mutually exclusive events with P(A)= 0.3 and P(B)= 0.5, then P(A and B)=
arsen [322]

Answer:

P (A\ and\ B) = 0

Step-by-step explanation:

By definition if two events are mutually exclusive then they are disjoint events, that is, they can not occur at the same time.

In general terms we say that events are mutually exclusive, then:

P (A\ and\ B) = 0

In this case we have that

P(A)= 0.3\\\\P(B)= 0.5

But A and B are mutually exclusive events, then P (A\ and\ B) = 0
