From the given graph, the numeric values of the expressions are given as follows:
f(-1) = 12.f(1) - g(1) = 8.g(x) = 4 when x = 2.f(x) = g(x) when x = 3.How to find the numeric value of a function or of an expression?To find the numeric value of a function, we replace each instance of the variable in the function by the desired value.
On the graph of the function, the equivalent to this is that we have to find where the x-axis has the value, and find the value of y for which the function passes through the y-axis.
From the graph, when x = -1, f(x) passes the point at y = 12, hence f(-1) = 12.
For the second item, applying the same logic, we have that:
f(1) = 10.g(1) = 2.Hence:
f(1) - g(1) = 10 - 2 = 8.
For the third item, we have to look at the graph of g(x), and find the value of x when y = 4, hence g(x) = 4 when x = 2.
For the fourth item, the functions intersect at point (3,8), hence f(x) = g(x) when x = 3.

The length of a colorado brook trout is normally distribute. what is the probability that a brook trout's length exceeds the mean? (round your answer to 2 decimal places.) the likelihood of a value greater than the mean is .50 because the whole area under the curve is 1 and the mean is the midway point.
Answers
The probability that a brook trout's length exceeds the mean is 0.50.
How to find the probability in normal distribution?One of the benefits of normal distributions is that we can find probabilities without being given the parameters of the distribution. This is achieved provided that we know the number of standard deviations from the mean the value of the random variable that delimits the indicated interval is.
We are given;
Distribution of length of a Colorado brook trout; Normal Distribution
Now, we want to find the likelihood of a value greater than the mean is 0.50.
We also know that if it is seen that the shape of the data is almost like a bell shape, then the data will be considered to have a normal distribution.
Thus, by the property of a normal distribution, the probability is 0.50.

A 30cm 40cm page of a book includes a 2cm margin on each side, as shown. What percentage of the page is occupied by the margins
Answers
If a (30cm by 40cm) page of a book includes a 2cm margin on each side, then the margins occupy 11.67 percentage of the total surface area of one side of the pages.
As per the question statement, a (30cm by 40cm) page of a book includes a 2cm margin on each side.
We are required to calculate the percentage of the total surface area of one side of the pages, occupied by the margins.
To solve this question, first we will need to calculate the total surface area of one side of the pages, and also the surface area occupied by the margins on one side, and then simply, calculate the percentage amount between the two area values.
Since the dimensions of the pages of the book are (30cm by 40cm), therefore, area of one side of each page = (30 * 40) sq. cm.
= 1200 sq. cm.
And, area occupied by the margins on each side of the page
= [(2 * 30) + (2 * 40)] sq. cm.
= (60 + 80) sq. cm.
= 140 sq. cm.
Therefore, percentage of the total surface area of one side of the pages, occupied by the margins = [(140/1200) * 100] = 11.67%

It is given in the question that the equation y = 0.74x + 64 gives the cost y of renting a car if the car is driven x miles.
It is a linear equation in 2 variable.
We have to find, for every mile the car is driven the cost increases by how much.
As we can observe from the equation, 64 is the fixed cost of renting a car, $ 0.74 is the cost of driving per mile.

2) Multiply both sides by 4 to make y by itself.
-1/2 * 4 = -2 (Multiply the top by 4 and you will get -4/2 = -2)
-3/5x * 4 = -12/5x (Multiply the top by 4 and you will get -12/5x)

We will see that the first term is $50, and the common difference is $25, then the recursive formula is:

We know that the first value (the first amount that she has in her savings account) is $50, so we can write the first term as:
a₁ = $50
Now, each new year (the subindex "n" represents the number of the year) $25 are added to that savings account, then we will have:
a₂ = $50 + $25 = $75
