Answer:
The probability experiment represents a binomial experiment
Step-by-step explanation:
On a Binomial experiment we have the following:
- There are n identical experiment
- Every experiment has 2 possibilities: success or fail
- There is a probability p of success and (1-p) of fail
- Every experiment is independent
Therefore, the probability experiment represents a binomial experiment because we have:
- The investor purchases 3 stocks listed on a stock exchange
- Every stock has 2 possibilities: increase in value over the course of a year or doesn't increase in value over the course of a year
- There is a probability of 0.49 that the stock increase in value over the course of a year and a probability of (1-0.49) that the stock doesn't increase in value over the course of a year
- The probability that every stock listed on this exchange increase in value over the course of a year is independent.
So, the probability that x stocks from the 3 that the investor purchases increase in value over the course of a year is equal to:
Where n is 3, and p is 0.49

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

Rewriting the whole as an Equivalent Fraction
2.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 6 as the denominator :
3 3 • 6
3 = — = —————
1 6
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
b - (3 • 6) b - 18
——————————— = ——————
6 6

When a fraction equals zero
3.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
b-18
———— • 6 = 0 • 6
6
Now, on the left hand side, the 6 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
b-18 = 0
Solving a Single Variable Equation:
3.2 Solve : b-18 = 0
Add 18 to both sides of the equation :
b = 18
One solution was found :
b = 18

I think a hint is that his youngest kids name is Justice which has 7 letters in it so he is 7 yrs old... That could be a hint but I'm not sure.
Answer:
Yes
Step-by-step explanation:
Geometric sequence is by multiplication, the sequence is constantly being multiplied by 1/2. So the ration would be 1/2.
