Assume the $26,000 Treasury bill, 5% for 13 weeks. Calculate the effective rate of interest.
Note: Use calendar year. Round your answer to the nearest hundredth percent.
Effective rate of interest
Simple interest of $325 was accrued on a principal of $26,000.00 for a period of 0.25 years (13 weeks) at a rate of 5% per year, bringing the total amount due to $26,325.00 (principal plus interest).
What is simple interest?Simple interest is calculated based on a loan's principal or the initial deposit into a savings account. Simple interest doesn't compound, so a creditor will only charge interest on the principal sum, and a borrower will never be required to pay additional interest on the interest that has already accrued.
Here,
A = $26,325.00
I = A - P = $325.00
A is equal to P(1 + rt).
The first step is to convert R percent to r a decimal, which is equal to R/100 = 5%/100 = 0.05 per year.
For ease, let's convert time to years: 13 weeks / 52 weeks / year = 0.25 years.
How to resolve our equation
A = 26000(1 + (0.05 × 0.25)) = $26,325.00
Simple interest accrued on a principal of $26,000.00 at a rate of 5% per year for 0.25 years (13 weeks) totaling $26,325.00 (principal plus interest).

Find the average rate of change of f(x) = -x² + 3x + 1 from x=2 to x = 5.
Simplify your answer as much as possible.
Answer:
The average rate of change is: -4
Step-by-step explanation:
So to solve this we just need to plug our numbers into the formula. We are using the formula f(b) - f(a)b - a where “a” and “b” are our numbers. So we are given the intervals x=2 and x=5. When we see that we can rewrite it as (2,0) and (5,0). This is because when it is telling us just “x” we know “y” (the second number in the parentheses) is 0. So just plugging in the numbers we get: (-(5)2+3(5)+1)-(-(2)2+3(2)+1)(5 - 2). Solving it we get -4.

Unitary method:
The method by which first we find the value of single unit and then the value of the required number of units is known as the Unitary Method.
Given,
Here we have given that, A recipe that makes 3 dozen chocolate chip cookies calls for 2 and 2/5 cups of flour.
So, here we need to find the following:
a) Exactly how much flour would you need for half the recipe?
b) Exactly how much flour would you need to make 5 dozen cookies?
In order to find these value, we have to calculate the amount of flour need for 1 dozen.
In order to calculate that, one we need to divide the total amount by the cups of flour need.
Then we get,
=> 3/ (2 2/5)
=> 3/ (12/5)
=> 15/12
=> 1.25
So, for half dozen cookies, we need
=> 1.25/2
=> 0.625
Which is in the fraction form of,

line m passes through the points (-4, 3) and (-4, 7) what is the slope of the line that is perpedicular to the line m
Answer:
The slope is 4 and the equation is y = 4x + 18
Step-by-step explanation:
Okay, so you start by solving for the slope. The formula for slope is
m = y1-y2 over x1-x2 (it looks lke a fraction)
then you plug in your coordinates, so it becomes:
m = 7-3 over -4 - (-4) which then you get your slope as 4, but because it has to be perpendicular, the slope becomes -1/4. this is because the slope has to be the reciprocal and the opposite sign to be perpendicular.
Then, you can continue to create the equation by using point-slope form, which is y - y1 = m (x-x1) (y1 and x1 are from the coordinates btw)
so the point-slope equation is:
y - 3 = -1/4 (x + 4)
y - 3 = -1/4x - 1
+3 +3
y = -1/4x + 2 (this is your equation in slope - intercept form)

what ticket price would maximize revenue?
As per the concept of system of linear equations, the maximum revenue of this basket ball match is $3.4
Linear equation:
Linear equation refers the one variable is an equation in which there is only one variable present. And it is of the form Ax + B = 0, where A and B are any two real numbers and x is an unknown variable that has only one solution.
Given,
A baseball team plays in a stadium that holds 66000 spectators. With the ticket price at $10 the average attendance has been 28000. When the price dropped to $7, the average attendance rose to 33000. Assume that attendance is linearly related to ticket price.
Here we need to find the ticket price would maximize revenue.
In order to find the ticket price for the maximum revenue,
We have to identify the details from the given question,
Total seating capacity = 66,000
When ticket price $10 then the attendance 28,000
When ticket price $7 then the attendance 33,000
Let us consider the x be the maximum revenue ticket price.
Now, to solve this we have to find the slope for the equation,
That is,
=> m = (33000 - 28000)/(7 - 10)
=> m = 5000/-3
=> m = -5000/3
=> m = 1666.6
Then the revenue equation is written as,
=> y = (10 - x) * (28,000 + 1666.6x)
=> y = 280000-11334x-1666.6x²
If we plot the this function into the graph, then we get the graph like the following.
Therefore, the solution of the graph is 3.4.

Step-by-step explanation:
Part AIf the spider's movement is modeled by a parabola, and its maximum height is 20 mm halfway across a horizontal distance of 160 mm, then:
x-intercepts = (0, 0) and (160, 0)Vertex = (80, 20)Standard form of a parabola with a vertical axis of symmetry:
[tex]\boxed{(x-h)^2=4p(y-k) \quad \textsf{where}\:p\neq 0}[/tex]

[tex]\implies (-80)^2=4p(-20)[/tex]
[tex]\implies 6400=-80p[/tex]

Substitute the found value of p and the vertex into the formula to create the equation of the parabola in standard form:
[tex]\implies (x-80)^2=4(-80)(y-20)[/tex]
[tex]\implies (x-80)^2=-320(y-20)[/tex]
Part BGiven:

Opinion polls find that 45% of teens say that their parents put at least some pressure on them to get into a good college. If you take an SRS of 980 teens, X has a distribution of the number in your sample who say they feel at least some pressure from their parents to get into a good college.
The variable X has a binomial distribution, as:
It has a fixed number of observations.The trials are independent.For each outcome, there are only two possible outcomes.What are the requirements for the binomial distribution?There are three requirements for the binomial distribution to represent a variable, as follows:
Fixed number of trials.The result of each trial is independent of the result of any other trial.Two possible outcomes for each trial, one representing a success and the other representing a failure.In the context of the variable X, these requirements are respected as follows:
Fixed number of 980 trials.For each trial, there is a 45% probability that the teen says that their parents put some pressure on him/her to get on good college, and 55% that the parents do not put pressure.For each trial, there are only two possible outcomes, either the parents put pressure, or they do not.Hence yes, the variable X has a binomial distribution.
