% of consumers believe that cash will be obsolete in the next 20 years. Assume that consumers are randomly selected. Find the probability that fewer than of the selected consumers believe that cash will be obsolete in the next 20 years.
Using the binomial distribution, it is found that there is a 0.4113 = 41.13% probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years.
For each consumer, there are only two possible outcomes, either they believe cash will be obsolete in the next 20 years, or they do not believe it. The belief of each customer is independent of any other customers, hence the binomial distribution is used to solve this question.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.Researching the problem on the internet, we have that:
40.4% of consumers believe that cash will be obsolete in the next 20 years, hence p = 0.404.7 customers are surveyed, hence n = 7.The probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years is given by:
[tex]P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)[/tex]
In which:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{7,0}.(0.404)^{0}.(0.596)^{7} = 0.0267[/tex]
[tex]P(X = 1) = C_{7,1}.(0.404)^{1}.(0.596)^{6} = 0.1268[/tex]
[tex]P(X = 2) = C_{7,2}.(0.404)^{2}.(0.596)^{5} = 0.2578[/tex]
Then:
[tex]P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0267 + 0.1268 + 0.2578 = 0.4113[/tex]
There is a 0.4113 = 41.13% probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years.

The solution to the equation is : ( B ) x = 6
Determine the solution of the equationGiven that the equation is

Barbara’s equation did not consider the number of bottles of iced tea. Barbara’s equation did not use the correct price for the bottles of iced tea. Barbara's equation did not use the correct total for sales.
Answer:
Barbara’s equation did not consider the number of bottles of iced tea.
Explanation:
She made this error because she included 1.25 with the x variable but did not include the x variable next to 1.49.
The x variable is important because it can keep track of how many bottles were sold of each water and tea.
So, this means Barbara’s equation did not consider the number of bottles of iced tea.
The real equations should be 1.25x + 1.49x = 100

Suppose that the mean daily viewing time of television is 8. 35 hours. Use a normal probability distribution with a standard deviation of 2. 5 hours to answer the following questions about daily television viewing per household.
The probability that a household views television between 5 and 10 hours a day is : 0.6553
Given data :
mean daily viewing time ( μ ) = 8.35 hours
standard deviation ( σ ) = 2.5 hours
Determine the probability of a household view btw 5 and 10 hours a dayP ( 5 ≤ x ≤ 10 )
= P ((5 - 8.35 )/2.5 < z < ( 10 - 8.35 )/2.5)
= P ( -1.34 < z < 0.66 )
Therefore the probability P ( 5 ≤ x ≤ 10 ) becomes
P( z < 0.66 ) - P ( z < -1.34 )
= 0.7454 - 0.0901 ( applying normal tables )
= 0.6553

Two years ago your orange orchard contained 70 trees, and the yield per tree was 70 bags of oranges. Last year you removed 10 of the trees and noticed that the yield per tree increased to 75 bags. Assuming that the yield per tree depends linearly on the number of trees in the orchard, what should you do this year to maximize your total yield?.
The number of trees that maximizes the yield is 105, so he should plant another 45 trees.
How to maximize the yield?
We know that the yield depends linearly on the number of trees. Remember that a linear relation is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
And we know that if a line passes through two points (x₁, y₁) and (x₂, y₂), then the slope can be written as:
[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Here we have the two points:
(70 trees, 70 bags)
(60 trees, 75 bags)
Then the slope is:
[tex]a = \frac{7 bags - 75 bags}{70 trees - 60 trees} = -0.5 bags/tree[/tex]
Then the linear equation is, ignoring the units, something like:
y = -0.5*x + b
To find the value of b we can use one of the known points, for example, the first one.
(70, 70)
70 = -0.5*70 + b
70 = -35 + b
70 + 35 = b = 105
Then the linear equation is:
y = -0.5*x + 105
This gives the yield per tree, and the total yield for the x trees will be x times the above quantity, so we define the total yield as:
T = -0.5x^2 + 105*x
Notice that this is a quadratic equation with a negative leading coefficient, meaning that the maximum is at the vertex.
And for a general quadratic function a*x^2 + b*x + c the vertex is at:
x = -b/2a
So in our case, the vertex is at:
x = -105/(2*(-0.5)) = 105
So to maximize the total yield, he should plant 45 more trees, to get a total of 105 trees.

An item that normally sells for $230 is marked down by 30%. What is the sale price?.
Answer:
$161 dollars
Explanation:
Given the following question:
30% of 230
In order to find the answer, we calculate the percent by multiplying the two by each other, and then dividing by 100.
[tex]\frac{30\times230}{100} =30\times230=6900\div100=69[/tex]
[tex]=69[/tex]
Now that we know the percentage of the item, we now subtract that answer by the initial amount the item would have sold for.
[tex]230-69=161[/tex]
The sale price is "$161 dollars."
Hope this helps.
