Express your answer in slope-intercept form. (If necessary, round the slope to the nearest hundredth and the y-intercept to the nearest whole number.)
Answers
ANSWER
y = 3.5x + 56
EXPLANATION
The slope of a line passing through points (x1, y1) and (x2, y2) is,
\(m=\frac{y_2-y_1_{}}{x_2-x_1}\)And the slope-intercept form of the equation of a line is,
\(y=mx+b\)Where m is the slope and b is the y-intercept.
In this problem, we have to use points (5, 73) and (7, 80) to find the equation of the line. First, we can find the slope,
\(m=\frac{80-73}{7-5}=\frac{7}{2}\)For now, the equation is,
\(y=\frac{7}{2}x+b\)We have to find the y-intercept, by replacing x and y for the coordinates of one of the given points,
\(80=\frac{7}{2}\cdot7+b\)And solve for b,
\(80=\frac{49}{2}+b\)\(b=80-\frac{49}{2}=\frac{160-49}{2}=\frac{111}{2}\)The equation is,
\(y=\frac{7}{2}x+\frac{111}{2}\)The slope as a decimal is 3.5 and the y-intercept, rounded to the nearest whole number is 56, so the equation is y = 3.5x + 56
2.40 in how many ways can 5 starting positions on a basketball team be filled with 8 men who can play any of the positions?
Answers
There are 6720 ways of selecting 5 starting positions out of 8 men.
The total number of ways of selecting 5 starting positions out of 8 men is given by the formula:
nCr = n! / r! * (n-r)!
where n is the total number of men (8) and r is the number of starting positions (5).
nCr = 8! / 5! * (8-5)!
nCr = 8! / 5! * 3! nCr = 8! / (5*4*3*2*1)
nCr = 8! / (120)
nCr = 6720
Therefore, there are 6720 ways of selecting 5 starting positions out of 8 men. This means that the 8 men can be arranged in 6720 different ways to fill the 5 starting positions on the basketball team.

A 19-inch piece of steel is cut into three pieces so that the second piece is twice as long as the first piece, and the third piece is three inches more than five times the length of the first piecefind the lengths of the pieces. 3 + 5x
Answers
Using algebraic expressions and equations to solve this problem, a 19- inch piece of steel is cut into three pieces measuring 2 inches, 4 inches, and 13 inches.
An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".
If the second piece is twice as long as the first piece, we can write this as an algebraic expression "2x" where x is the length of the first piece.
If the third piece is three inches more than five times the length of the first piece, we can write this as an algebraic expression "3 + 5x" where x is the length of the first piece.
If the three pieces were cut from a single piece of steel 19-inches long, we can write the equation for the sum using the algebraic expressions.
let x = length of first piece
2x = length of second piece
3 + 5x = length of third piece
x + 2x + 3 + 5x = 19 inches
Solving for x,
8x = 19 -3
8x = 16
x = 2 inches
length of first piece = 2 inches
Substitute the value of x in the expressions for the second and third piece.
length of second piece = 2x
length of second piece = 2(2)
length of second piece = 4 inches
length of third piece = 3 + 5x
length of third piece = 3 + 5(2)
length of third piece = 3 + 10
length of third piece = 13 inches

Answers
a. The equation that represents the situation is x/12 = 24
b. The number of songs oliver downloaded is 288 songs
What is an equation?An equation is a mathematical expression that shows the relationship between two variables.
a. What is an equation that represents this situation?Since number of songs oliver has downloaded this year, divided by 12, is equal to 6 less than 30.
Let x represent the number of songs.
Since number of songs oliver has downloaded this year, divided by 12, we have that x/12 is the first part of the simple equation.
Also, since this equals 6 less than 30, we have that the equation equals
x/12 = 30 - 6
x/12 = 24
So, the equation is x/12 = 24
b. How many songs has oliver downloaded?Since x/12 = 24 represent s the situation and x represent s the number of songs oliver downloaded, making x subject of the formula, we have
x/12 = 24
x = 24 × 12
x = 288 songs

What is the area of an equilateral triangle with side √ 3 4 * 1 point?.
Answers
Answer:
3/4 square points
Step-by-step explanation:
An equilateral triangle is a triangle with all sides of equal length.
To find the area of an equilateral triangle, we can use the formula:
Area = (√3/4) * (side length)^2
In this case, the side length is √3/4 * 1 point. To calculate the area, we need to square the side length first.
(√3/4 * 1)^2 = (√3/4)^2 * 1^2 = (3/4) * 1 = 3/4
So, the area of the equilateral triangle is 3/4 square points.

what should be t-value to indicate that curve is not over flattening in smoothening of time series data
Answers
When smoothing time series data, it's important to ensure that the curve is not over-flattened, as this can lead to important information being lost.
What should be t-value to indicate that curve is not over flattening?To avoid over-flattening, one approach is to use a threshold value, or "t-value", to determine the maximum amount of smoothing that can be applied.Here are some steps to consider when choosing a t-value:Plot the original time series data and the smoothed curve to visualize the smoothing effect.Compare the slope of the smoothed curve to the slope of the original data.Choose a t-value that preserves the important features of the original data, such as trends, seasonality, and outliers.Ensure that the smoothed curve still accurately represents the underlying pattern in the data, while reducing noise and variability.Re-evaluate the t-value if necessary, based on the visual comparison of the original data and the smoothed curve.The t-value should be chosen such that the smoothed curve captures the underlying pattern in the data, while retaining important features such as trends and seasonality. If the t-value is set too high, the curve may become over-flattened and important information may be lost. On the other hand, if the t-value is set too low, the curve may not effectively reduce noise and variability in the data.To learn more about T-value refer:

Martin dennis brought a wide screen television for $1720. He made a down payment of 15% and paid the balance over 18 months. The fiance charge was 4% of the amount financed. Find the down payment and the installment price of the televison and the monthly payment
Answers
Answer:
Down payment is $258
Installment price is $1766.22
monthly payment is $83.79
Step-by-step explanation:
Down payment is 15% of $1,720 which is $258 (15%*$1720)
Monthly payment can be computed using pmt formula in excel
=pmt(rate,nper,-pv,fv)
rate is the interest rate per month which 4%/12=0.33%
nper is the number of months of payments that is 18
pv is the finance amount which is the price minus down payment i.e $1462 *($1720-$258)
fv is the total finance amount plus interest which is unknown i.e 0
=pmt(0.33%,18,-1462,0)=$ 83.79
installment price =down payment +total repayment
=$258+($83.79*18)=$1766.22

Answers
To find the value of f(6), we can use the information given about the function f(x) and its derivative f'(x).The value of f(6) is 44/3.
Given that f'(x) is continuous, we can apply the Fundamental Theorem of Calculus. According to the theorem:
∫[a to b] f '(x) dx = f(b) - f(a)
In this case, we are given that:
∫[1 to 6] 6 f '(x) dx = 16
We can simplify the integral:
6 ∫[1 to 6] f '(x) dx = 16
Since f'(x) is the derivative of f(x), the integral of 6 f '(x) dx is equal to 6 f(x). Therefore, we have:
6 f(6) - 6 f(1) = 16
Substituting the given value f(1) = 12:
6 f(6) - 6(12) = 16
6 f(6) - 72 = 16
Next, we isolate the term with f(6):
6 f(6) = 16 + 72
6 f(6) = 88
Finally, we solve for f(6) by dividing both sides by 6:
f(6) = 88 / 6
f(6) = 44/3

About how many times greater was change in price per gallon in 2007 than 2000? Show your work or explain how u determind your answer.
Answers
The required, in 2007 the price per gallon was 7b more than the price of a gallon of fuel in the year 2000. Where b is the inflation factor.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Let 'a' be the cost per gallon of fuel in the year 2000, and 'b' be the inflation rate per year. If the rate of inflation is constant then
After 7 year inflation = 7b
Cost of fuel in 2007 = a + 7b
Now,
according to the question
Change in cost of fuel
= cost in 2007 - cost in 2000
= a + 7b - a
= 7b
Thus, the required, in 2007 the price per gallon was 7b more than the price of a gallon of fuel in the year 2000. Where b is the inflation factor.
