Probability that the arrow will stop on the same letter twice = 1/3 (c).

What is probability?

The area of arithmetic called likelihood deals with numerical representations of the chance that a happening can occur or that an announcement is true.

Main body:

Given : Maria will spin the arrow on the spinner 2 times.

To find : What is the probability that the arrow will stop on the same letter twice.

Solution : We have given a spinner that spin twice and stop on the same letter.

Formula for probability = no. of favourable outcome/ total outcomes

Here, total part of spinner = 3 and it spin two times

So, total possible outcome = 6.  Arrow stay on same letter twice( favorable outcome) =2.

Plugging the values in formula :

Probability =  2/6

Probability =  1/3

Therefore,  probability that the arrow will stop on the same letter twice =  (c).

Using the Factor Theorem, the length of one side of the garden is:

(3x - 4) feet.

The Factor Theorem states that a polynomial function with roots \(x_1, x_2, \codts, x_n\) is given by:

\(f(x) = a(x - x_1)(x - x_2) \cdots (x - x_n)\)

In which a is the leading coefficient.

The area of a rectangle is given by the multiplication of it's dimensions. In this problem, it is given by:

A = 9x² - 24x + 16.

The root of 9x² - 24x + 16 = 0 is x = 4/3 with multiplicity 2, hence:

\(x_1 = x_2 = \frac{4}{3}\)

Hence the area can be written as:

\(A = 9\left(x - \frac{4}{3}\right) \times \left(x - \frac{4}{3}\right)\)

Then, to find one side:

9(x - 4/3) = 9x - 12 = 3(3x - 4).

Hence (3x - 4) feet is one side.

Step-by-step explanation:

Design of Experiments (DOE) is a statistical methodology that is used to systematically change input variables or process parameters to discover the effect of these changes on the output variables.

DOE is a critical tool used in the manufacturing industry, pharmaceuticals, and many other sectors. The cake making process is a simple example of how DOE is used. Consider a case where we want to optimize a recipe for a cake mix.

The following are some input factors that might affect the quality of the cake mix:

The response variable for the experiment is cake texture, as it will be measured using the following factors:

After determining the response and input variables, the next step is to identify levels and ranges for the input factors. As an example, we may use the following levels for the input variables:

Amount of butter: 25, 50, 75, 100

Sugar concentration: 20, 30, 40, 50

Egg yolk quantity: 1, 2, 3, 4

Amount of flour: 100, 200, 300, 400

Baking temperature: 150, 160, 170, 180

Mixing time: 5, 10, 15, 20

In a standard DOE, a full factorial experiment is carried out in which every possible combination of the different levels of input variables is tested. The output of each test run is then recorded, and statistical analysis is performed to identify which input variables have the greatest effect on the output variables.

By using DOE, we can optimize the recipe for a cake mix by finding the ideal combination of input variables that result in the best cake texture.

Answer:

7,000 - 2,386 = 4,614

Answer: \(h(x)=10(0.4)^x\)

Step-by-step explanation:

The exponential function h, represented in the table, can be written as \(h(x)=ab^x\)

From table, at x=0, h(x) =10

Put theses values in equation,, we get

\(10=a.b^0\\\\\Rightarrow\ 10= a (1)\\\\\Rightarrow\ a= 10\)

Also, for x= 1 , h(x) = 4, so put these values and a=10 in the equation , we get

\(4=10b^1\\\\\Rightarrow\ b=\dfrac{4}{10}\\\\\Rightarrow\ b= 0.4\)

Put value of a and b in the equation ,

a) To create a balanced data set with a proportion of fraudulent records at 20%, we need to calculate the number of fraudulent records that need to be resampled.

Let's denote the total number of fraudulent records that need to be resampled as \(x\). The total number of records in the balanced data set will be \(10,000 + x\).

The proportion of fraudulent records in the balanced data set is given as 20%. This means that the number of fraudulent records in the balanced data set should be 20% of the total number of records.

Setting up the equation:

\(\(\frac{{\text{{number of fraudulent records}}}}{{\text{{total number of records}}}} = \frac{{400 + x}}{{10,000 + x}} = 0.20\)\)

Simplifying the equation:

\(\(400 + x = 0.20(10,000 + x)\)\(400 + x = 2,000 + 0.20x\)\(x - 0.20x = 2,000 - 400\)\(0.80x = 1,600\)\(x = \frac{{1,600}}{{0.80}}\)\(x = 2,000\)\)

Therefore, 2,000 fraudulent records need to be resampled in order to achieve a balanced data set with a proportion of fraudulent records at 20%.

b) To calculate the number of non-fraudulent records that need to be set aside, we first need to determine the number of total records in the balanced data set. We already know that the total number of records in the training set is 10,000.

Since the proportion of fraudulent records in the balanced data set should be 20%, the remaining 80% of the balanced data set will consist of non-fraudulent records.

Let's denote the number of non-fraudulent records that need to be set aside as \(y\). The total number of records in the balanced data set will be \(y + 400\).

Setting up the equation:

\(\(\frac{{\text{{number of fraudulent records}}}}{{\text{{total number of records}}}} = \frac{{400}}{{y + 400}} = 0.20\)\)

Simplifying the equation:

\(\(400 = 0.20(y + 400)\)\(400 = 0.20y + 80\)\(0.20y = 320\)\(y = \frac{{320}}{{0.20}}\)\(y = 1,600\)\)

Therefore, 1,600 non-fraudulent records need to be set aside in order to achieve a balanced data set with a proportion of fraudulent records at 20%.

It will take 12 more minutes for the remaining 75% of the movie to download using algebra.

To determine how many minutes are needed for the remaining 75% of the movie to download, we will follow these steps:

1. Observe that the movie has been downloading for 4 minutes and has downloaded 25%. This means that the time taken to download 25% of the movie is 4 minutes.
2. Now, we need to determine the time taken to download the remaining 75% of the movie. Since we know the time taken for 25%, we can use this information to find the time for 75%.
3. We can set up a proportion: (time taken for 25%)/(time taken for 75%) = 25%/75%. This proportion helps us understand the relationship between the time taken for both percentages.
4. Plug in the known value: 4 minutes/(time taken for 75%) = 25%/75%. Now, we need to solve for the unknown variable (time taken for 75%).
5. To solve for the unknown variable, we can cross-multiply. Multiply 4 minutes by 75% and 25% by the time taken for 75%: (4 minutes x 75%) = (25% x time taken for 75%).
6. Calculate 4 minutes x 75%: 4 minutes x 0.75 = 3 minutes. So, 3 minutes = (25% x time taken for 75%).
7. Now, divide both sides of the equation by 25% (or 0.25) to find the time taken for 75%: 3 minutes ÷ 0.25 = 12 minutes.

So, it will take 12 more minutes for the remaining 75% of the movie to download.

Answer:

\(\textsf{A)} \quad -1\dfrac{3}{20}y+4\)

Step-by-step explanation:

Given expression:

\(\left(11-9 \dfrac{3}{5}y\right)+\left(8 \dfrac{9}{20}y-7 \right)\)

Remove the parentheses:

\(11-9 \dfrac{3}{5}y+8 \dfrac{9}{20}y-7\)

Collect like terms:

\(8 \dfrac{9}{20}y-9 \dfrac{3}{5}y+11-7\)

Subtract the numbers 11 - 7:

\(8 \dfrac{9}{20}y-9 \dfrac{3}{5}y+4\)

Factor out y:

\(\left(8 \dfrac{9}{20}-9 \dfrac{3}{5}\right)y+4\)

Partition the mixed numbers into fractions and whole numbers, and then subtract them separately.

Subtract the whole numbers:

\(\implies 8-9=-1\)

Subtract the fractions by changing both fractions into equivalent fractions so both fractions have the same denominator:

\(\implies \dfrac{9}{20}-\dfrac{3}{5}\)

\(\implies \dfrac{9}{20}-\dfrac{3 \cdot 4}{5 \cdot 4}\)

\(\implies \dfrac{9}{20}-\dfrac{12}{20}\)

\(\implies -\dfrac{3}{20}\)

Put the two answers from the whole numbers and fractions back together:

\(\implies -1-\dfrac{3}{20}=- \left(1+\dfrac{3}{20}\right)=-1\dfrac{3}{20}\)

Therefore:

\(\left(8 \dfrac{9}{20}-9 \dfrac{3}{5}\right)y+4=\left(-1\dfrac{3}{20}\right)y+4=-1\dfrac{3}{20}y+4\)
