Julie opens a retirement account, starting with 1,300, that earns an annual
interest rate of 4.5%, compounded annually. What is Julie’s account balance
after 15 years? Round your answer to the nearest dollar.
Use A = P(1 + r)t
Answer:
$20377.50
Step-by-step explanation:
A = P(1 + r)t
P = 1300
r = 4.5% = 0.045
t = 15 years
Let's solve
A = 1300(1 + 0.045)15
A = 1300(1 .045)15
A = $20377.50
There are 30 students in a class. Today, 26 students are present. Choose an equation to show how many students are absent.
Responses
26+a=30, a=4; 4 students are absent.
26 plus A is equal to 30, , A is equal to 4, ; , 4 students are absent.,
26+30=a, a=56; 56 students are absent.
26 plus 30 is equal to A, , A is equal to 56, ; , 56 students are absent.,
a−26=30, a=56; 56 students are absent.
A minus 26 is equal to 30, A is equal to 56; 56 students are absent.
26−a=30, a=4; 4 students are absent.
The equation that represents the number of absent students is:
30 - 26 = a
so a = 4, there are 4 absent students.
Which equation shows how many students are absent?We know that there are 30 students in a given class, and particularly, today there are 26 students present.
We want to find an equation that gives the number of students absent, and that would be equal to the difference between the total number of students (30) and the number of present students (26)
Then we will get the equation:
30 - 26 = a
Solving that we get:
30 - 26 = a
4 = a
There are 4 absent students.

Approximate the intervals where each function is increasing and decreasing.
Given is the parabola opening down.
It increases up to vertex and then decreases in value.
The vertex is at (3, 4) so the intervals are:
Increase: ( - ∞, 3],Decrease: [3, ∞).Answer:
Increasing: (-∞, 3)
Decreasing: (3, ∞)
Step-by-step explanation:
A function is increasing when the slope is positive (y gets bigger as x gets bigger).
A function is decreasing when the slope is negative (y gets smaller as x gets bigger).
From inspection of the given parabola, the turning point is (3, 4).
The function is increasing as the curve approaches the turning point.
The function is decreasing as the curve approaches infinity after the turning point.
Therefore, the intervals where the function is increasing and decreasing are:
Increasing: (-∞, 3)Decreasing: (3, ∞)Note: x = 3 is not included in the intervals, as the curve is not increasing or decreasing when x = 3. There is a turning point (stationary point) at x = 3 which means the slope is zero as this point. Therefore, the function is not increasing or decreasing when x = 3.

What kind of circumstances would lead you to writing a function versus using a loop?
When utilising a loop, you cannot update something in the code or add a new feature. Instead, you use functions. Therefore, if you wish to modify the function you are re-calling, you should use a function rather than a loop.
When should you use a function vs a loop?Similar to how a loop represents a piece of code that we want to run repeatedly, a function represents a piece of code that may be called at any moment and executed. For example, in the source code's current location, a certain loop construct could only be executed once. A computer function known as a loop repeats a statement or condition based on predetermined boundaries. In all programming languages, the loop function has nearly the same logic and syntax.The primary purpose of the concept of function is to enable code reuse. It can be used for two separate things, such as repeatedly invoking the same function within a programme and allowing users to apply the same function to several contexts after it has been generated.To learn more about function refer to:

Constant variance is the assumption in regression analysis that the standard deviation and variance of the residuals are constant for all values of the independent variables.
Constant variance is the assumption in regression analysis that the standard deviation and variance of the residuals are constant for all values of the independent variables.
Homogeneity of variances means the assumption that the variances of the random variables are constant. This homoscedasticity (that is, constant variances) assumption can be tested using the same diagnostics used for linear regression models.
All data usually consist of the dependent variable and the independent variable itself. Constant variance is about many linear regression assumptions. For example, if you have 325 rows, there should be at least one variance, possibly a constant. The next question is how to compare variables with appropriate variances. The basic fact is that when plotting between a single value and a predicted value, the resulting variance should be constant for the prediction error value.

Why must the base of a logarithm be a positive real number not equal to 1?
The base of a logarithm must be a positive real number and not equal to 1 because logarithms are defined as the inverse operation of exponentiation. The base must be a positive real number to be able to raise it to the power of the argument and not equal to 1 to get a meaningful result.
The base of a logarithm represents the number that is being raised to a certain power to produce the argument of the logarithm. If the base of a logarithm is not a positive real number, it is not possible to perform this inverse operation.
For example, if the base of a logarithm is 0, it would mean that the argument of the logarithm is being raised to the power of 0, which is always 1. Therefore, the logarithm would be 0 for any argument, which does not provide any useful information.
The base of a logarithm must be a positive real number and not equal to 1 because it is not possible to raise 1 to any power to produce any value other than 1. Therefore, a logarithm with base 1 is not a meaningful concept.

A bag contains 6 white and 4 black balls .2 balls are drawn at random. Find the probability that they are of same colour.
The probability that they share the same color is 7/15.
What is probability ?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.
An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
The likelihood that an event will occur increases with its probability.
A straightforward illustration is tossing a fair (impartial) coin.
The chance of both outcomes ("heads" and "tails") is equal because the coin is fair, "heads" is more likely than "tails," there are no other conceivable outcomes, and the likelihood of either outcome is half (which may also be.
According to our question-
Then n(S)= number of ways of drawing 2 balls out of (6+4)=10
Let E= event of getting both balls of same color
Then, n(E)= no of ways (2 balls out of six) or (2 balls out of 4)

What is expression?
In mathematics, an expression is a combination of numbers, symbols, and operators (such as +, -, *, /) that represent a mathematical relationship or value.
The problem is asking us to find the value of q − 6 when q is equal to −16. To do this, we need to substitute −16 for q in the expression q − 6, which gives us:
q - 6 = (-16) - 6
We then simplify the expression by subtracting 6 from −16, which gives us:
q - 6 = -22
So, the value of q − 6 when q = −16 is −22. This means that if we had a number line and plotted −16 on it, then moved 6 units to the left, we would land on the number −22.

If both variables tend to deviate in the same direction (both go above their means or below their means at the same time), then the covariance will be positive.
What Is Covariance?
The direction of the link between the returns on two assets is measured by covariance. Asset returns move together when the covariance is positive, and inversely when the covariance is negative.
It is calculated by analyzing at-return surprises (standard deviations from the expected return) or multiplying the correlation between the two random variables by the standard deviation of each variable.
Types of Covariance:-
This link is determined by a covariance value, either positive or negative.
When two variables have a positive covariance, it means that they frequently tend to be higher or lower together.When the estimated covariance is less than zero, it means that there is an inverse link between the two variables.Covariance Calculated:-
Covariance = Σ[tex][ ( Return_{abc} - Average_{abc} ) * ( Return_{abc} - Average_{abc} ) ][/tex]÷ [ Sample Size - 1 ].
