=break your pencil lead while writing, and = feel overly stressed.
=put together a swing set correctly, and =read the directions.
These are independent events because the occurrence of one event does not affect the occurrence of the other event. Breaking a pencil lead while writing and feeling overly stressed may happen at the same time, but one event does not cause the other. Similarly, putting together a swing set correctly and reading the directions are independent events because one action (reading the directions) does not determine the outcome of the other action (assembling the swing set correctly).
=make an error on your income tax return, and =file Form 1040 long.
These are dependent events because the occurrence of one event (making an error on the tax return) affects the occurrence of the other event (filing Form 1040 long). If you make an error on your tax return, you may need to file a longer form to correct it.
=have a salad with dinner, and =work on a home project.
These are also dependent events because one event (having a salad with dinner) does not determine the outcome of the other event (working on a home project). These events may happen at the same time, but one does not cause the other.
A 20-year annuity is such that the first payment of $x is made at the end of the first year, and that subsequently, payments increase in such a way that each payment is 104% of the preceding one. If the present value of this annuity is $7229.50, find the value of x to the nearest integer.
Take the effective annual rate of interest to be 7%.
The value of x to the nearest integer is $294.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
We can use the formula for the present value of an increasing annuity to solve this problem:
PV = x/(i-g) × (1 - (1+g)/(1+ i)ⁿ)
where PV is the present value,
x is the first payment,
i is the effective annual interest rate,
g is the annual increase rate of the payments, and
n is the total number of payments.
Substituting the given values, we have:
7229.50 = x/(0.07-0.04) (1 - (1+0.04)/(1+0.07)²⁰)
Simplifying and solving for x, we get:
x = 7229.50×0.03 × (1 - 1/1.07^20) / (1.04 × (1 - 1/1.07²⁰))
x= $294
Therefore, the value of x to the nearest integer is $294.

Find the value of X , Y, and z in the parallelogram below.
Answer:
[tex]x = -64\\\\y = -63\\\\z = -57[/tex]
Step-by-step explanation:
Diagonally opposite angles of a parallelogram are equal
Therefore
-y - 3 = 60
Add 3 to both sides; -3 terms on left side cancel out
- y = 60 + 3
- y = 63
Multiply both sides by -1
-1(-y) = -1(63)
y = - 63
Another property of a parallelogram is that the angles formed on either end by a side must equal 180°.
Rephrased,
The consecutive or adjacent angles are supplementary which means they add up to 180°
We see that -2z + 6 and 60° are adjacent angles
So
- 2z + 6 + 60 = 180
-2z + 66 = 180
-2z = 180 - 66
-2z = 114
z = 114/-2
z = -57
Similarly
-2x - 8 + 60 = 180
-2x + 52 = 180
-2x = 180 - 52
-2x = 128
x = 128/-2
x = -64

Timothy, Laurence and Mike went to a bookstore to buy some books. The ratio of the number of books bought by Laurence and Mike were 2: 7. Timothy and Laurence bought a total of 20 books while Timothy and Mike bought a total of 35 books. How many books did Timothy buy?
Answer:
[tex]\mbox{\large \textsf{Timothy bought 14 books}}[/tex]
Step-by-step explanation:
Let's use first letters of names to represent the number of books bought by that person. This makes it easier to explain.
Therefore, the books bought by each of the three persons are T(imothy), L(aurence) and M(ike)
We will now convert each of the word description into math equations and solve
We are given that the ratio of the number of books bought by Laurence and Mike were 2: 7
We can write this as:
[tex]\dfrac{L}{M} = \dfrac{2}{7}\\\\[/tex]
Multiplying both sides by M:
[tex]L = \dfrac{2}{7}M\cdots\cdots(1)[/tex]
Timothy and Laurence bought a total of 20 books can be represented as
[tex]T + L = 20\cdots\cdots(2)[/tex]
Timothy and Mike bought a total of 35 books can be represented as
[tex]T + M = 35\cdots\cdots(3)[/tex]
Eq (3) - Eq (2):
[tex]T + M - (T + L) = 35 - 20\\\\T + M - T - L = 15\\\\M - L = 15 \cdots\cdots (4)[/tex]
Substituting for [tex]\displaystyle L = \frac{2}{7}M[/tex] from equation (1) into equation (4) we get
[tex]M - \dfrac{2}{7}M = 15\\\\\dfrac{5}{7}M = 15\\\\M = \dfrac{7}{5} \times 15\\\\M = 21\\\\[/tex]
Given [tex]\displaystyle M = 21[/tex] using equation (3), [tex]\displaystyle T + M = 35[/tex] we get
[tex]T + 21 = 35\\\\T = 35 - 21\\\\\textrm{or}\\\\T = 14[/tex](Answer)
If we wanted to find out how many books Laurence bought use Eq(1)

On the graph, we have the following readings:
A root of multiplicity 1 at x = -1A root of multiplicity 1 at x = 1A root of multiplicity 2 at x = 2y-intercept = -12A polynomial is represented as
P(x) = a * (x - zero)^multiplicity
Using the above as a guide, we have the following:
P(x) = a * (x + 1)(x - 1)(x - 2)^2
The y-intercept is -12
So, we have
a * (0 + 1)(0 - 1)(0 - 2)^2 = -12
This gives
a = -4

Find the GCF of the terms of each polynomial 15x^2+18 and -18y^4+6y^3+24y^2
The GCF of the polynomials are
1. for 15x²+18 , the GCF is 3
2. for -18y⁴+6y³+24y² ,the GCF is 6y²
What is GCF?The GCF stands for the “greatest common factor”. The GCF is defined as the largest number that is a factor of two or more numbers. For example, the GCF of 24 and 36 is 12, because the largest factor that is shared by 24 and 36 is 12. 24 and 36 have other factors in common, but 12 is the largest.
The GCF is the highest factor that can be used to divide through 2 or more terms
1. For 15x²+18, 3 is a factor of 15 and 18 and it's the greatest factor, therefore the GCF is 3
2. For -18y⁴+6y³+24y², between 18,6 and 24, 6 is the greatest factor Ang between y⁴ ,y³, y², y² is the greatest factor. Therefore the GCF of the expression is 6y².

Answer:
$3.25 per hotdog
Step-by-step explanation:
This question can be written as a system of equations:
x = price of hotdogs
y = price of drinks
First family:
4x + 4y = 18
Second family
5x + 3y = 20
Multiply each equation so that one of the variables can cancel out:
-3(4x + 4y = 18)
4(5x + 3y = 20)
First equation:
-12x - 12y = -54
Second equation
20x + 12y = 80
Add the equations together
-12x - 12y = -54
20x + 12y = 80
8x = 26
Divide
x = $3.25
Insert the x into one of the original equations to find y:
4(3.25) + 4y = 18
13 + 4y = 18
4y = 5
y = $1.25

Riding equation of the line that has the same slope as 3X minus 2Y equals 12 in the same y-intercept as 5Y +21 equals 4X
The linear equation can be written as:
y = (3/2)*x - 21/5
How to write the linear equation?
A general linear equation can be written as:
y = m*x + b
Where m is the slope and b is the y-intercept.
First, we know that our line has the same slope than:
3x - 2y = 12
Rewriting that we will get:
3x - 2y = 12
3x - 12 = 2y
(3/2)x - 12/2 = y
So the slope of this line is (3/2).
And our lie has the same y-intercept as 5y + 21 = 4x
We can rewrite that to get:
5y = 4x - 21
y = (4/5)x - 21/5
The y-intercept is -21/5
Then the linear equation is:
