Answers
given the equation:

to complete the table for the values of x and y using intergers
fristly,
when x = -4
y = 5/4(-4) - 3
y = -5 - 3
y = -8
when x = 0
y = 5/4(0) - 3
y = 0 - 3
y = -3
when = 4
y = 5/4(4) - 3
y = 5 - 3
y = 2
when x = 8
y = 5/4(8) - 3

What is an equation?An equation is an expression that can be used to show the relationship between numbers and variables.
The equation of a line in slope intercept form is:
y = mx + b
Where m is the slope and b is the y intercept
Two lines are parallel if they have same slope

Answers
Given:
[tex]\begin{gathered} \mu=10\text{ }inches \\ \sigma=2.2\text{ inches} \end{gathered}[/tex]To find- P(X>15)
Explanation-
We know that a z-score is given by-
[tex]z=\frac{x-\mu}{\sigma}[/tex]where x is the raw score, mu is the mean and sigma is the standard deviation.
Hence, the proportion of trees having a diameter greater than 15 inches will be-
[tex]\begin{gathered} P(x>15)=P(\frac{x-\mu}{\sigma}>\frac{15-\mu}{\sigma}) \\ P(x>15)=P(Z>\frac{15-10}{2.2}) \end{gathered}[/tex]On further solving, we get

The slopes to the linear functions are given as follows:

What is the slope of a linear function?A linear function is modeled according to the following rule:
y = mx + b.
The coefficient m represents the slope of the linear function, which is the rate of change, given by change in y divided by change in x.
When two functions are parallel, they have the same slope. In item 2, the function is defined as follows:
-7x - 2y = 6.
In slope-intercept format, the function is given by:
2y = -7x - 6
y = -3.5x - 3.
Hence the slope of the parallel line is of -3.
Given two points, the slope is given by change in y divided by change in x. For problem 3, the two points are given as follows:
(-7,0) and (9,-1).
Hence the slope is given by:
m = (-1 - 0)/(9 - (-7)) = -1/16 = -0.06.

By solving the equation we know that Amy's school sold 30 tickets to seniors and 42 tickets to children.
What are equations?A mathematical statement called an equation includes the symbol "equal to" between two expressions with equal values. Consider the formula 3x + 5 = 15. Different types of equations exist, including linear, quadratic, cubic, and others. Any value of the variable that satisfies the equality, that is, makes the Left Hand Side (LHS) and the Right Hand Side (RHS) of the equation equal, is a solution of the equation. Finding an equation's solution or solution is known as solving the equation.So, let 's' represents seniors and 'c' represents children.
The equation is as follows:
6s + 15c = 810 - 6(s + c = 72)⇒ -6s - 6c = -432 (Cut s)Then,
9c = 378c = 378/9c = 42Then,
s = 72 - 42s = 30Therefore, by solving the equation we know that Amy's school sold 30 tickets to seniors and 42 tickets to children.

Suppose the First Bank of Lending offers a CD (Certificate of Deposit) that has a 6.45% interest rate andis compounded quarterly for 3 years. You decide to invest $5500 into this CD.a) Determine how much money you will have at the end of three years.b) Find the APY.
Answers
In order to solve this, we have to use the compound interest formula given by the following expression:
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]Where r is the interest rate, P is the initial amount deposited, n the number of times the period is compounded a year, t the year, and A the final amount.
By replacing 0.0645 (6.45%) for r, 4 for n, 3 for t and 5500 for P into the above equation, we get:
[tex]A=5500(1+\frac{0.0645}{4})^{4\times3}=6663.8978[/tex]Then, after 3 years you will have $6663.9.
In order to determine the APY, we can use the following formula:
[tex]APY=100\times((1+r/n)^n-1)[/tex]Where n is the number of times the interest is compounded a year (4) and r is the rate of interest (0.0645), then we get:
[tex]APY=100\times((1+0.0645\/4)^4-1)=6.61[/tex]Then, the APY equals 6.61%
Leila deposits the same amount of money into a bank account every month. The table below shows the amount of money in the account after different amounts of time.
Answers
To see how money is changing with respect to time, we will observe the time and money value differences between two periods.

We can see that within a two month increase, the amount of money has also increased.
We can observe the values for 10 and 12 months and see that these months are also asscociated with increased account values.
a)
Correct option: As the time increases the amount of money in the account increases.
Rate of increase:
r = (557-467)/2 =
$45 dollars per month.
We are asked to find the amount of money at time t= 0 months.
Since then, the amount in the account has increased 6 times. It has increased by $270.
