a1 = -2 r=-2 Sn=22 Determine the number of terms of n in the series
A series can be an arithmetic series or geometric series
The series is undefined
How to determine the number of terms?The given parameters about the geometric series are:
a1 = -2 --- the first term
r=-2 --- the common ratio
Sn=22 --- the sum of n terms
The sum of n terms of a geometric series is represented as:
\(S_n = \frac{a(r^n - 1)}{(r-1)}\)
Substitute known values
\(22 = \frac{-2((-2)^n -1)}{(-2-1)}\)
This gives
\(22 = \frac{-2((-2)^n -1)}{(-3)}\)
Divide both sides by -2
\(-11 = \frac{((-2)^n -1)}{(-3)}\)
Multiply both sides by -3
\(33 = (-2)^n -1\)
Add 1 to both sides
\((-2)^n = 34\)
Take the natural logarithm of both sides
\(n\ln(-2) = \ln(34)\)
Solve for n
\(n= \frac{\ln(34)}{\ln(-2) }\)
The above number is a complex number.
Hence, the series is undefined

a) In this test of the hypotheses H0 : μ = 12 versus H1 : μ ≠ 12, the P-value is 0.4.
So, should H0 be rejected on the basis of this test?NoThe reason is that P = 0.4 is not small.
If the P-value were smaller, it would be more surprising to see the observed sample result if H0 were true.
But since the P-value is not small, the observed result does not provide convincing evidence against H0.
So, we cannot reject H0.
b) Can you conclude that the machine is calibrated to provide a mean fill weight of 12 oz? No. We cannot conclude that the null hypothesis is true.
The null hypothesis is plausible and the alternate hypothesis is false.
However, the fact that we cannot reject H0 does not mean that we can conclude H0 is true.

8. A tire dealer sells Supreme tires for $48 each and Prestige tires for $56 each. During one week, the sales for both tires totaled $2008. If 11 Prestige tires were sold, write and solve a linear equation to find the number of Supreme tires sold.
Answer:
31 Supreme tires were sold.
Step-by-step explanation:
Cost of one Supreme tire = $45
Cost of one Prestige tire = $56
Total sales = $2008
Let x represent quantity of supreme tyre
Let y represent quantity of Prestige tyre
So, the equation will be:
\(45x+56y=2008\)
11 Prestige tires were sold, write and solve a linear equation to find the number of Supreme tires sold.
So, we are given y= 11 and we need to find value of x using above equation
\(45x+56y=2008\\45x+56(11)=2008\\45x+616=2008\\45x=2008-616\\45x=1392\\x=\frac{1392}{45}\\x=30.933\\ x\approx31\)
So, 31 Supreme tires were sold.

Several different roadways are in the same region as the railroad.
Part A: A highway's path can be found using the equation 2x+3y=21. Use the graphs of the functions to determine the number of intersections there will be between the railroad and the
highway, and explain completely. (5 points)
Part B: A turnpike's route is determined by the equation y=x2 Prove algebraically how many intersections there will be between the railroad and the turnpike, showing all necessary
work. (5 points)
There are 0 intersections between the railroad and the highway and there are 2 intersections between the railroad and the turnpike
The number of intersections there will be between the railroad and the highwayFrom the graph, we have the following points on the railroad
(x, y) = (3, 3) and (0, 5)
The slope is calculated as:
m = (y2 - y1)/(x2 - x1)
This gives
m = (5 -3)/(0 - 3)
Evaluate
m = -2/3
The equation is then calculated as:
y = mx + b
This gives
y = -2/3x + b
Substitute (0, 5)
5 = -2/3 * 0 + b
This gives
b = 5
Substitute b = 5 in y = -2/3x + b
y = -2/3x + 5
Multiply through by 3
3y = -2x + 15
Rewrite as:
2x + 3y = 15
The equation of the highway's path is
2x+3y=21
So, we have:
2x+3y=21
2x + 3y = 15
Subtract the equations
2x - 2x + 3y - 3y = 21 - 15
Evaluate
0 = 6
The above equation is false because 0 and 6 are not equal.
This means that the system of equations have no solution
Hence, there are 0 intersections between the railroad and the highway.
How many intersections there will be between the railroad and the turnpike?Here, we have
y = x^2 and 2x + 3y = 15
Substitute y = x^2 in 2x + 3y = 15
2x + 3x^2 = 15
Rewrite as:
3x^2 + 2x - 15 = 0
Calculate the discriminant using
d =b^2 - 4ac
This gives
d = 2^2 - 4 * 3 * -15
Evaluate
d = 184
The discriminant d is greater than 0.
This means that the equation has 2 real solutions
Hence, there are 2 intersections between the railroad and the turnpike

You want to have your carpet cleaned in your living room which measures 11’ by 14’. A company charges $2.75 per square foot and company B charges $450 per room. Which company should you hire to get a better deal?
Answer:
Since, company A charge of $423.5 is less than company B charge of $450
Hence,
Company A should be hired to get the better deal.

What is sine?
Sine is a trigonometric function that relates the ratio of the length of the side opposite an angle in a right triangle to the length of the hypotenuse. In a right triangle, the sine of an angle is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse.
Mathematically, the sine function is denoted as sin(x), where x is the angle. The sine function takes an angle in radians as its input and returns the corresponding sine value.
By using the identity \(sin^2(x) + cos^2(x) = 1\), we can rewrite sin °x as (1 - cos 2x) sinx.
Then, we can make the substitution u = cos x, which allows us to express the integral in terms of u. This substitution simplifies the integral and makes it easier to evaluate.
Therefore, the correct method to integrate sin °x is to rewrite it as (1 - cos 2x) sinx and then use the substitution u = cos x.

The weights of six dogs in kilograms are: 12.1, 14.3, 10.8, 14.0, 10.7 and 15.5. Calculate the mean weight correct to one decimal place.
The mean weight of the six dogs is 12.9 kilograms (correct to one decimal place).
To calculate the mean weight of the six dogs, we need to add up the weights of all the dogs and divide by the total number of dogs.
The sum of the weights of the six dogs is:
12.1 + 14.3 + 10.8 + 14.0 + 10.7 + 15.5 = 77.4
There are six dogs, so the mean weight is:
mean weight = sum of weights / number of dogs = 77.4 / 6 = 12.9

7x + 15 = 9x - 1
To solve we must move the Xs on one side of the = sign and the free numbers on the other. For that, we must do the same operations on both sides. If we subtract from one, from the other also, and so on.
So we are going to substract 15
(7x + 15) - 15 = (9x - 1) -15
It result:
7x = 9x - 16
We are going to substract 9x
(7x) - 9x = (9x - 16) - 9x
It result:
7x - 9x = -16
-2x = -16
We are going to change the signs (ON BOTH SIDES)
2x = 16
x = 8
now we have the value of X
we substitute x in the equations
7(8) + 15 = 9(8) - 1
56 + 15 = 72 - 1
71 = 71
So, the angles are 71°
And the Value of X is 8°through: (2,-1), parallel to y=-2/3x-3
