The table shows the results for spinning the spinner 80 times. What is the relative frequency for the event spin a 3?Outcome - 1, 2, 3, 4Frequency - 20, 10, 22, 28Number of trials - 80
Answers
Solution
- The formula for finding the relative frequency for an event is:
\(\text{ Relative Frequency}=\frac{\text{ Event Frequency}}{\text{ Total Frequency}}\)- The Event of spinning a "3" occurred 22 times. This means that
\(\text{ Event Frequency }=22\)- The total frequency is gotten by adding up all the frequencies. That is,
\(20+10+22+28=80\)- Thus, we can find the Relative Frequency of getting a 3 as follows:
\(\text{ Relative Frequency}=\frac{22}{80}\)Final Answer
The Relative Frequency of getting a 3 is:
\(\text{ Relative Frequency}=\frac{22}{80}\)

The equations are:
\(4H + 3P = 13.75\)
\(2H + 5P = 11.25\)
\(Hotdog = 2.50\)
\(Pretzel = 1.25\)
Step-by-step explanation:
Let:
\(H = hot\ dog\)
\(P =Pretzel\)
For Tina:
\(4H + 3P = 13.75\)
For Doug:
\(2H + 5P = 11.25\)
Solving for the price of both items:
We have:
\(4H + 3P = 13.75\) --- (1)
\(2H + 5P = 11.25\) --- (2)
Multiply (2) by 2
2 * (\(2H + 5P = 11.25\))
-------------------
\(4H + 10P = 22.50\) --- (3)
Subtract (3) from (1)
\(4H + 3P = 13.75\)
\(4H + 10P = 22.50\)
----------------------
\(4H - 4H + 3P - 10P = 13.75 - 22.50\)
\(3P - 10P = 13.75 - 22.50\)
\(-7P = -8.75\)
Solve for P
\(P = \frac{-8.75}{-7}\)
\(P = 1.25\)
Substitute 1.25 for P in (2)
\(2H + 5P = 11.25\)
\(2H + 5 * 1.25 = 11.25\)
\(2H + 6.25 = 11.25\)
Collect Like Terms
\(2H = 11.25-6.25\)
\(2H = 5\)
Solve for H
\(H = \frac{5}{2}\)
\(H = 2.50\)

using calculus, determine the value of c that minimizes mse(c). you must justify that this is indeed a minimum, and not a maximum.
Answers
The value of c that minimizes MSE is given by the equation above:
c = sum(y * x) / sum(x²)
Minimize MSE with CalculusTo determine the value of c that minimizes the mean squared error (MSE), we must first find the derivative of MSE with respect to c and set it equal to zero. This will give us the critical points, which can then be tested to determine if they correspond to a minimum or maximum.
Let MSE be denoted as J(c). The derivative of J with respect to c is given by:dJ(c) / dc = 2 * sum((y - (c * x)) * (-x)) / n
Setting this derivative equal to zero and solving for c, we find the critical point:c = sum(y * x) / sum(x²)
Next, we must determine if this critical point corresponds to a minimum or a maximum. To do this, we can take the second derivative of J with respect to c and evaluate it at the critical point:d² J(c) / dc² = -2 * sum(x²) / n
Since this second derivative is negative, it indicates that the critical point corresponds to a minimum, not a maximum. Thus, the value of c that minimizes MSE is given by the equation above:c = sum(y * x) / sum(x²)
Note that this method assumes that J(c) is a convex function, which is typically the case for the MSE loss function.

O 19.5%
O 18.4%
Answers
Answer:
To calculate the percent increase in the amount of interest paid between a household with a 740 credit score and one with a 730 credit score , we need to find the total amount paid for each score and then calculate the percent increase.
From the given table , we can see that the simple interest rate for a credit score of 740-799 is 15%, and the total number of payments is 33 . So, the total amount paid for a principal balance of $18,000 with a credit score of 740 is:
Principal + Total Interest = Total Amount Paid
$18,000 + ($18,000 * 15% * 33/12) = $20,700
Similarly, for a credit score of 730, we need to use the simple interest rate for a credit score of 670-739 , which is 18%, and the total number of payments is 38. So, the total amount paid for a principal balance of $18,000 with a credit score of 730 is:
Principal + Total Interest = Total Amount Paid
$18,000 + ($18,000 * 18% * 38/12) = $21,240
Now, to calculate the percent increase in the amount of interest paid , we can use the following formula:
Percent increase = |(New value - Old value) / Old value| * 100%
Plugging in the values, we get:
Percent increase = |($21,240 - $20,700) / $20,700| * 100%
Percent increase = 2.6%
Rounding to the nearest tenth, we get the final answer as:
Percent increase = 2.6% ≈ 2.5% (rounded to the nearest tenth)
Therefore, the answer is O 2.5%.

From 4.85x, the committee wants to have $450 remaining, so we can set up an equation.
The equation will be \(4.85x - 450 = C\)
So, to get maximum budget for equipment and costumes, we need to maximize the cost of equipment and costumes. This occurs when the cost is equal to the left side of the equation above.

Write the equation of the line that has slope 3 and passes through the point
(-2,5).
Answers
y=mx +c
where m is the slope, c is a constant, and x and y are variables,
we know the slope is 3 so m=3
rewriting it
y=3x +c
to find c we substitute values x=-2 and y=3 into the equation y=3x +c
so
3= 3(-2) + c
c=9
thus, y=3x+ 9
Explanation:
y = kx+m is the equation of a line. The coefficient of x is the slope i.e 3. So we know that a part of the equation is y = 3x + m.
How to find M?
Well, we already have a point on the equation. Meaning we already have an x and a y. -2 = x and 5 = y.
The equation then becomes 5 = (3 x -2) + m.
Solve for m and the answer will be m = 11.
Now we have both m and K meaning that the whole equation is solved and it’s y = 3x + 11

How is the least common multiple determined for the two expressions?
Answers
The least common multiple of two numbers is the first number that can divide them
We have the terms
\(25v^8u^4,10v^2u^6w^3\)We will find the least common multiple of 25 and 10
Since the multiples of 25 are
\(25,50,75,100,\ldots\)Since the multiples of 10 are
\(10,20,30,40,50,60,\ldots\)The first common multiple in both lists is 50, then
The least common multiple of 25 and 10 is 50
For the same variables, we will choose the greatest exponent
For v
\(v^8,v^2\rightarrow v^8\)The least common multiple of v is v^8
For u
\(u^4,u^6\rightarrow u^6\)The least common multiple of u is u^6
For w
\(w^3\rightarrow w^3\)The least common multiple w is w^3
Then the least common multiple of the 2 terms is
\(50v^8u^6w^3\)

Answers
The algebraic rule for the transformation is B' = (Bx + 15, By - 12)
Given data ,
To determine the algebraic rule for the transformation from point B to point B', we need to find the equations that relate the coordinates of the preimage point B to the image point B'.
Let's denote the translation amounts in the x-direction and y-direction as (dx, dy). The coordinates of B' can be obtained by adding these translation amounts to the coordinates of B:
B' = (Bx + dx, By + dy)
Given that B is located at (5, -4) and B' is located at (20, -16), we can calculate the translation amounts:
dx = 20 - 5 = 15
dy = -16 - (-4) = -12
Hence , the algebraic rule for the transformation is B' = (Bx + 15, By - 12)
