Due to a negative value of P(X = x), it is found that the following is not a probability distribution.

---------------------

A sequence (x, P(X = x)) is a probability distribution if:

  • The sum of all values of P(X = x) equals 1.
  • There is no negative values of P(X = x).

In this problem, P(X = 2) is negative, thus, it is not a probability distribution.

4= 6/a + 5 solve for x
Scorpion4ik [409]

Answer:

a=-6

Step-by-step explanation:

4= 6/a + 5

Subtract 5 from each side

4-5= 6/a + 5 -5

-1 = 6/a

Multiply by a on each side

-1*a = 6/a *a

-a =6

Multiply by -1

a= -6

Sam invests $800 at 6%/a compounded annually for 5 years. What is the total interest<br> earned?
s2008m [1.1K]
<h3>Answer:    270.58 dollars</h3>

======================================================

Work Shown:

  • A = account value after t years
  • P = principal or amount deposited = 800
  • r = interest rate in decimal form = 0.06
  • n = number of times we compound per year = 1
  • t = number of years = 5

So,

A = P*(1+r/n)^(n*t)

A = 800*(1+0.06/1)^(1*5)

A = 1070.58046208

A = 1070.58

After five years, the account will have $1,070.58 in it.

The amount of interest earned is A-P = 1070.58 - 800 = 270.58 dollars.
