Vivian has $57,366.66 in a savings account. The interest rate is 9 2/5%, compounded annually.
To the nearest cent, how much interest will she earn in 4 years
Answer:20652.00
Step-by-step explanation:
The formula would be p*r*t
p is the principal which is amount of money before interest
r is the interest rate
t is time period
so it would be 57,366.66*9 2/5%*4
9 2/5 as a decimal would be 9.4 or 0.09
57,366.66*9.4=539246.604*4=2156986.416
The correct amount would be $20652.00 in 4 years
Use 0.09 when u multiply instead of 9.4 because it is much easier

The questions pertain to the analysis of linear relationships between variables using scatter plots, lines of best fit through linear regression, and understanding correlation coefficients to identify the strength and direction of relationships in data.
Explanation:The questions provided are centered around the concepts of linear equations, scatter plots, correlation, and regression analysis in the realm of mathematics. Scatter plots are graphical representations showing the relationship between two variables. In these types of questions, the independent variable is plotted on the x-axis, and the dependent variable is plotted on the y-axis. To analyze the relationship, one can use linear regression to find the line of best fit, which is a straight line that best represents the data on a scatter plot. The correlation coefficient, often denoted as r, indicates the strength and direction of the linear relationship between two variables.
The line of best fit can be found by calculating the least-squares line, which minimizes the sum of the squares of the vertical distances of the points from the line. The equation of this line is typically in the form y = a + bx, where 'a' is the y-intercept and 'b' is the slope. The slope indicates how much the dependent variable changes for a one-unit change in the independent variable. The y-intercept is the value of the dependent variable when the independent variable is zero. A correlation coefficient of zero implies no linear relationship between the variables.
When looking at data such as stock market trends or health-related measurements like BMI and cholesterol, understanding the strength and type of correlation is essential for making predictions. For example, a positive correlation indicates that as one variable increases, the other variable tends to increase, while a negative correlation indicates the opposite. It's important to note that correlation does not imply causation; just because two variables are correlated does not mean that one causes the other.

Factor the expression using the GCF.
14x + 63
Help! Please
The final factored expression using the GCF is: 14x+63=7(2x+9)
To factor the expression 14x + 63 using the Greatest Common Factor (GCF), let's first find the GCF of the numerical coefficients 14 and 63. The largest number that divides both 14 and 63 without a remainder is 7, making it the GCF.
Next, we divide each term by the GCF:
14x divided by 7 is 2x
63 divided by 7 is 9
Now that we have divided each term by the GCF, we can write the original expression as a product of the GCF and the simplified expression:
14x + 63 = 7(2x + 9)
This expression is fully factored as the product of the GCF (7) and the binomial (2x + 9).

A theater is selling tickets for a performance. Mr. Smith purchased 8 senior tickets and 5 child tickets for $136 for his friends and family. Mr. Jackson purchased 4 senior tickets and 6 child tickets for $96. What is the price of a senior ticket?
Answer:
The price of a senior ticket is $12.
Step-by-step explanation:
Given:
Mr. Smith purchased 8 senior tickets and 5 child tickets for $136. Mr. Jackson purchased 4 senior tickets and 6 child tickets for $96.
Now, to get what is the price of a senior ticket.
Let the senior ticket be [tex]x[/tex] and the child ticket be [tex]y[/tex]:
So, according to question
[tex]8x+5y=136[/tex].........(1)
[tex]4x+6y=96[/tex]...........(2)
Now, we have system of equations:
Multiplying the equation (2) by -2 we get:
[tex]-8x-12y=-192[/tex].......(3)
Now, adding the equation (3) and (1) the variables and the numbers:
[tex]-8x-12y+8x+5y=-192+136[/tex]
[tex]-7y=-56[/tex]
Dividing both sides by -7 we get:
[tex]y=8[/tex]
Putting the value of y in equation (2) we get:
[tex]4x+6(8)=96[/tex]
[tex]4x+48=96[/tex]
On solving the equation we get:
[tex]x=12[/tex].
Therefore, the price of a senior ticket is $12.
A movie theater has n rows and m seats in each row. If each ticket costs $5.60, how much do all tickets to one movie cost?
Total cost of tickets for one movie showing is calculated by multiplying the total number of seats (n rows times m seats per row) by the cost per ticket, which is $5.60.
Explanation:To calculate the total cost of all tickets for one movie showing in a theater with n rows and m seats per row, you'll need to use multiplication to find the total number of seats and then multiply it by the cost per ticket. Here is a step-by-step guide:
Multiply the number of rows (n) by the number of seats per row (m) to find the total number of seats. This is n × m.Multiply the total number of seats by the cost per ticket, which is $5.60, to find the total cost for all tickets. This is (n × m) × $5.60.The final calculation will give you the total cost of tickets for one movie showing.For example, if a theater has 10 rows with 20 seats in each row, the total number of seats is 10 × 20 = 200. The total cost for all tickets would then be 200 × $5.60 = $1120.
If 4 quarts of paint are needed for a 75-foot fence, how many quarts are needed for an
825-foot fence?
Answer:
44 quarts of paint
Step-by-step explanation:
Given,
75-foot fence needs = 4 quarts.
We have to use the unitary method to determine how many quarts will be needed for the fencing system. Hence,
75-foot fence needs = 4 quarts of paint
1-feet fence needs = (4/75) quarts of paint
825-foot fence needs = (4 x 825)/75 quarts of paint
= 3,300/75 quarts of paint
= 44 quarts of paint
Therefore, we need 44 quarts of paint for 825-foot fence.
To determine how many quarts of paint are needed for an 825-foot fence, we can set up a proportion and solve for the unknown quantity.
Explanation:To determine how many quarts of paint are needed for an 825-foot fence, we can use the concept of ratios. Since we know that 4 quarts of paint are needed for a 75-foot fence, we can set up a proportion:
4 quarts of paint / 75 feet = ? quarts of paint / 825 feetTo solve for the unknown quantity, we can cross-multiply and solve for the missing value:
4 quarts of paint * 825 feet = ? quarts of paint * 75 feetDividing both sides of the equation by 75, we get:
? quarts of paint = (4 quarts of paint * 825 feet) / 75 feetBy performing the calculation, we find that quarts of paint is approximately 44 quarts. Therefore, 44 quarts of paint are needed for an 825-foot fence.

E
o y- 48 (2)
y (43)
O ya 4036
The expression will be y =8*2 or y = (48/6)*2
Step-by-step explanation:
The direct proportion is given if y varied directly as x
y∝x
When the proprtionality symbol is removed, a proportionality constant is introduced.
y = kx
as we know y = 48 when x = 6
[tex]48 = k * 6\\k = \frac{48}{6}\\k = 8[/tex]
The equation will be:
y = 8x
So when x=2
y = 8*2
y = 16
Hence,
The expression will be y =8*2 or y = (48/6)*2

To find the value of y when x is 2 in a direct variation, use the constant of variation k found from the given values (y = 48 when x = 6), which is 8 in this case, and multiply it by 2 to get y = 16.
If y varies directly as x, this means that y can be expressed as y = kx, where k is the constant of variation. Given that y = 48 when x = 6, we can find the value of k by substituting these values into the direct variation equation:
k = y/x = 48/6 = 8
Now that we have k, we can find the value of y when x is 2:
y = kx = 8 x 2 = 16
Therefore, the expression to find the value of y when x is 2 is y = 8 x 2.

Finding the Length of a Garden
To find the length of a rectangular garden when you know the perimeter and the width, you can use the formula for the perimeter of a rectangle, which is P = 2L + 2W, where P stands for the perimeter, L is the length, and W is the width. The student has provided that the width (W) of the garden is 90 feet and the perimeter (P) is 500 feet.
Substituting the values we know into the formula, we get:
500 = 2L + 2(90)
Now, we solve for the length (L) by following these steps:
First, do the multiplication: 500 = 2L + 180
Next, subtract 180 from both sides to isolate the term with L: 320 = 2L
Finally, divide both sides by 2 to solve for L: 160 = L
Therefore, the length of the garden is 160 feet.
Suppose the graph of y=f(x) includes the points (1,5), (2,3), and (3,1).
Based only on this information, there are two points that must be on the graph of y=f(f(x)). If we call those points (a,b) and (c,d), what is ab+cd?
Answer: 17
================================
How I got that answer:
(2,3) and (3,1) have '3' in common in that the y value of the first pairs with the x value of the second.
If you picture a chain, then you start with x = 2, move to y = 3, then move to x = 3 and then y = 1
2 ---> 3 ---> 3 ---> 1
So f(f(2)) = f(3) = 1
If g(x) = f(f(x)), then we know (2,1) is on the graph of g(x)
-------------------------
Repeat for (3,1) and (1,5)
3 ---> 1 ---> 1 ---> 5
f(3) = 1
g(x) = f(f(x)) = f(f(3)) = f(1) = 5
We know that (3,5) is on the graph of g(x)
-------------------------
The two points on g(x) are: (2,1) and (3,5)
Comparing that to (a,b) and (c,d) we can see
a = 2, b = 1, c = 3, d = 5
a*b + c*d = 2*1 + 3*5 = 2 + 15 = 17
