The probability that Mia is on time to exactly one of the classes is 0.5
Given that
probability of she is late for the art class (x)= 0.5
probability of she is late for the calculus class(y) = 0.4
the probability of she is not late for the art class (z)= 1 - x = 1 - 0.5 =0.5
the probability of she is not late for the calculus class(p)= 1 - y = 1 - 0.4 = 0.6
the probability that Mia is on time to exactly one of the classes =
Probability of arriving (late for Calculus and on time for Art)) or (late for Calculus and on time for Art)

methods. Which method is more accurate? Explain
We can solve the given linear equations using graphing and substitution method. Substitution is more accurate, since it provides an exact answer.(x,y)=(1.5,4.5) is the answer for the given linear equation.
What is Substitution and Graphing method ?As Math Planet correctly notes, to solve a system of linear equations by graphing, we simply graph both equations in the same coordinate plane and locate the intersection of the two lines. Substitution-Based Graphing of Linear Equations. By substituting values for x, we may obtain the appropriate y values and display the points on a line with the equation y = ax + b. (x, y). Two points must be produced by replacement in order to create a line between them.
Calculation:x + y = 6 → y = 6 − x
5x − y = 3
⇒5x − (6 − x) = 3
⇒5x + x − 6 = 3
⇒6x = 9
⇒x = 1.5
⇒1.5 + y = 6
⇒y = 4.5
(x,y)=(1.5,4.5)

What are the vertex and range of y = |x − 5| 4? (5, 4); −[infinity] < y < [infinity] (5, 4); 4 ≤ y < [infinity] (−5, 4); −[infinity] < y < [infinity] (−5, 4); 4 ≤ y < [infinity]
The range and the vertex is 4 ≤ y < [infinity] and (5, 4).
To find the vertex, we can take the derivative of the function and set it equal to 0:
y' = |x − 5|' = 0
=> x − 5 = 0
=> x = 5
Then, we can plug x = 5 into the original equation to find the y-value at the vertex:
y = |x − 5| = |5 − 5| = |0| = 0
So, the vertex of y = |x − 5| is (5, 4).
To find the range, we need to consider the range of the absolute value function. The range of the absolute value function is:
−[infinity] < y < [infinity]. So, the range of y = |x − 5| is also −[infinity] < y < [infinity] (or 4 ≤ y < [infinity]).

Monica would like to save up $10,000. She is going to make monthly deposits for 5 years into an account that will get 2.05% compounded monthly. How much does she need to deposit in the account to reach her goal?
The amount of money that Monica needs to deposit each month in order to save up $10,000 in 5 years is; $91017.17865
How to solve compound interest problems?The formula for compound interest is;
A = P (1 + r/n)^(nt)
where;
A is the total amount of money in the account after the interest has been compounded.
P is the initial deposit.
r is the interest rate.
n is the number of times the interest is compounded in a year
t is the number of years the money is deposited.
We are told that Monica would like to save up $10,000. Thus;
The initial deposit = $10,000.
The interest rate = 2.05%.
The number of times the interest is compounded per year; n = 12 (because the interest is compounded monthly),
The number of years the money is deposited; t = 5.
Plugging these values into the compound interest formula, we get:
A = 10000 (1 + (0.0205 / 12))^(12 * 5)
A = 10000 (1.001708333)^60
A = 10000 (1.101717865)
A = $101017.17865
Thus, the total amount of money in the account after 5 years will be $101017.17865.
Since Monica wants to save up $10,000, we can subtract this amount from the total amount in the account to find out how much she needs to deposit each month in order to reach her goal:
101017.17865 - 10000 = 91017.17865

Write a system of equations to model Monica's savings and Shanna's savings. Let x represent the number of weeks and y represent savings.
Type your response in the box
The system of equations to model Monica's and Shanna's savings is y = 10x + 50 for Monica and y = 15x + 100 for Shanna.
To model Monica's savings and Shanna's savings using a system of equations, we can use the variables x and y, where x represents the number of weeks and y represents the savings.
Let's start by defining the equation for Monica's savings. We'll use the equation y = mx + b, where m represents the savings per week and b represents the initial savings.
Next, let's define the equation for Shanna's savings. We'll use the same equation, y = mx + b, but with different values for m and b.
For example, let's say Monica saves $10 per week and initially has $50 in savings. The equation for Monica's savings would be y = 10x + 50.
Now, let's say Shanna saves $15 per week and initially has $100 in savings. The equation for Shanna's savings would be y = 15x + 100.
So, the system of equations to model Monica's and Shanna's savings would be:
Monica: y = 10x + 50
Shanna: y = 15x + 100
By using this system of equations, we can determine Monica's and Shanna's savings at any given number of weeks, x. Simply substitute the value of x into the equations and solve for y.

three people A, B, C, are to share 44,000usd among themselves in the ration a:b:c: respectively .if a = ½b c=⅓b how much will B receive more than C
There are B receives an amount of $35,733.33 more than C.
What is Ratio?A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
Let "b" be the amount that B receives.
A receives 1/2 × b, and C receives 1/3 × b.
The total amount that A and C receive is 1/2 × b + 1/3 × b = 5/6 × b.
Since A, B, and C are to share $44,000 in the ratio a:b:c, the total amount that A and C receive is 5/6 × b = $44,000.
Solving this equation for b, we get:
b = $44,000 / (5/6)
b = $44,000 x (6/5)
Apply the multiplication operation, and we get
b = $53,600
Therefore, B receives $53,600, and C receives 1/3 x $53,600 = $17,866.67.
B receives $53,600 - $17,866.67 = $35,733.33 more than C.

the mean of a distribution of data is 3.56 . if the distribution is symmetric , what is the median ?
Since, the mean of distribution of data is 3.56 then the median is also 3.56 because the distribution is symmetric.
Symmetric Distribution:
A symmetric distribution is when the values of a variable occur with regular frequency, often the mean, median, and mode all occurring at the same point. A line in the middle of the chart indicates that the two planes are mirror images of each other.
In graphical form, a symmetric distribution is displayed as a normal distribution (that is, a bell curve). Symmetric distribution is a central concept in technical trading as it assumes that the price movements of an asset over time follow a symmetric distribution curve. A symmetric distribution can be contrasted with an asymmetric distribution.
Relation between Median and Mean
A distribution always has a median and a mode, but not always a mean. Consider the Cauchy distribution. No average exists. Modes are always present, but may not be unique. This means that you can get a distribution that is not unimodal (that is, multimodal).
So, if we have a symmetric distribution with a mean and the distribution is unimodal, we can say:

A rectangular storage container without a lid is to have a volume of 10 m3. The length of its base is twice the width. Material for the base costs $5 per square meter. Material for the sides costs $3 per square meter. Let w denote the width of the base. Find a function in the variable w giving the cost C (in dollars) of constructing the box.
A function in the variable w giving the cost C is 81.77 dollars.
What is meant by volume?Volume is a unit of measurement for the area occupied in three dimensions. It is widely quantified and measured using SI-derived units, alternative imperial units, or US standard units (such as the gallon, quart, cubic inch). Volume and length (cubed) have a similar meaning.
First, volume was calculated using naturally occurring vessels with a similar shape, and then using standardized containers.
Surface area of an open lid container is:
A=2×sides+Base
So,
A=2(lh+wh)+lw
Cost of the base is $5 per square meter and the cost of the sides is $3 per square meter.
Now, the cost function is:
C=3×2(lh+wh)+5×lw
C=6(lh+wh)+51w
Here, the length is twice the width then,
l=2w
C=6(2wh+wh)+5×2w²
C=6(3wh)+10w²
C=18wh+10w²
And we know that the volume is,
V= lwh
2w²h=10
h=5/w²
C=18wh+10w²
C=18w×(5/w²)+10w²
C=(90/w)+w²
C'=(-90/w²)+20w
0=(-90/w)+20w
20w=(90/w²)
20w³=90
w³=45
w=1.65
C=(90/1.65)+10×1.65²
C=81.77

If the genome contained 20,000 genes, the average length of DNA per gene will be 40,000 base pairs.
What is the average length of DNA per gene?
