Algebra can be used to solve a random number problem by considering order of operations.
Step-by-step explanation:
Algebra is one of the broad parts of mathematics, together with number theory, geometry, and mathematical analysis. It is used to represent the letters and symbols than numbers and quantities.
Algebra is of two types
i.) Elementary algebra , ii.) Abstract algebra
Elementary algebra is used for any study and their applications.
Abstract algebra is used for advanced mathematics by professionals.
The order of operations in algebra means solving first for exponents or roots, then multiplication, division, addition, and last for subtraction. The steps for the order of operations also require attention to mathematical grouping symbols, such as parentheses and brackets.
To solve a random number problem using algebra, understand the problem's context, convert the numbers into usable formats, apply algebraic techniques, and verify the results. For instance, Lisa uses random numbers generated by a calculator to select class members uniquely. These steps help solve such problems efficiently.
Applying Algebra to Solve a Random Number Problem:
To apply algebra to solve a random number problem, follow these steps:
First, understand the context and problem requirements. For example, suppose Lisa needs to select class members using random numbers generated by a calculator.Convert the random numbers into usable groups or categories. In Lisa's case, she reads .94360 as 94, 43, 36, and 60, with each number representing a potential class member.Apply algebraic techniques to manage and convert these numbers appropriately. For example, if you need to sum, multiply, or find an average of these numbers, use algebraic operations like addition or division.Verify your final answer by ensuring it meets all the problem’s criteria and constraints. Since each random number may only contribute one class member, Lisa checks that she selects unique members.By following these steps, you can solve random number problems efficiently using algebra.
Random numbers can be generated using various tools like tables or calculators, and their manipulation often requires algebraic techniques. Using a combination of these methods allows one to solve real-world problems, such as selecting class members or calculating probabilities.

Write an exponential function in the form of y=ab* that goes through points (0,9) and (3,4608)
Answer:y=9(8)^x
Step-by-step explanation:
The exponential function that passes through the points (0,9) and (3,4608) is y = 9 * 8^x. This was determined by using the given points to find the values of a and b in the function y = ab^x.
Explanation:To write an exponential function that passes through the points (0,9) and (3,4608), we start with the general form y=abx. Using the given points, we can set up two equations based on their coordinates. The first point (0,9) leads to the equation 9 = a * b0, which simplifies to 9 = a since anything raised to the power of 0 is 1. The second point (3,4608) gives us 4608 = a * b3.
Now that we know a = 9, we can substitute it into the second equation to find the value of b: 4608 = 9 * b3. Dividing both sides by 9, we get 512 = b3, which leads to b = 8 after taking the cube root of 512. Thus, the exponential function we are looking for is y = 9 * 8x.

Help me, please ....
Answer:
see explanation
Step-by-step explanation:
The opposite angles of the inscribed quadrilateral are supplementary, thus
∠ A + ∠ C = 180°, substitute values
14z - 7 + 8z = 180
22z - 7 = 180 ( add 7 to both sides )
22z = 187 ( divide both sides by 22 )
z = 8.5
Thus
∠ A = 14z - 8 = 14(8.5) - 7 = 119 - 7 = 112°
∠ C = 8z = 8(8.5) = 68°
∠ D = 10z = 10(8.5) = 85°
The sum of the 4 interior angles = 360°, thus
∠ B = 360° - (112 + 68 + 85)° = 360° - 265° = 95°
Thus
∠ A = 112°, ∠ B = 95°, ∠ C = 68°, ∠ D = 85°

Which is the product of 4/9 and 72
Final answer:
The product of 4/9 and 72 is found by multiplying 4 by 72 and then dividing by 9, giving us the final answer of 32.
Explanation:
To find the product of 4/9 and 72, you multiply the two numbers together. Here's how you do it:
Write the multiplication expression: 4/9 × 72.
Since 72 is the same as 72/1, you can think of this as multiplying two fractions: (4/9) × (72/1).
Multiply the numerators together: 4 × 72 = 288.
Multiply the denominators together: 9 × 1 = 9.
Combine the results to find the fraction form of the answer: 288/9.
Simplify the fraction by dividing numerator and denominator by their greatest common divisor, which is 9: 288 ÷ 9 = 32.
The product of 4/9 and 72 is 32.

The isotope thulium-167 is used in laser scans for medical treatments. Its rate of decay is −0.075. How many days does it take 500 grams of the isotope to decay to 250 g?
Thank you!
9.24 days does it take 500 grams of the isotope to decay to 250 grams.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operation is called the arithmetic operator.
Operators which let do a basic mathematical calculation
Given that
The isotope thulium-167 is used in laser scans for medical treatments
The rate of decay is 0.075
The isotope thulium-167 is used in laser scans for medical treatments.
If we started with 500 grams then we are looking for when only 250 grams are left so
y = y₀e^(-0.075t)
y₀ represents the initial amount of radioactive material
250 = 500e^(-0.075t)
0.5 = e^(-0.075t)
Now take the natural log of both sides which gives us,
ln0.5 = -0.075t
t = ln0.5/(-0.075)
t = 9.24 days
Hence, 9.24 days does it take 500 grams of the isotope to decay to 250 grams.

A number cube with faces labeled from 1 to 6 was rolled 20 times. Each time the number cube was rolled, the number showing on the top face was recorded. The table shows the results.
Number Showing on Top Face Frequency
1 0
2 3
3 3
4 6
5 3
6 5
If you were to use these results to predict the probability of the next number showing on the top face, what type of probability would you be using?
A) Theoretical probability
B) Experimental probability
C) Independent probability
D) Dependent probability
Step-by-step explanation:
Theoretical probability : Theoretical probaility is the value expected from an outcome or an equation assuming perfect conditions. It is based on theories and hypotheisi and not based on real life incidents.
Experimental probability : When we performa n experiment, the values we get are experimental probability. These are actual rsults of the eperiemnt under study
Independent probability : Two events A and B are said to be independent if the fact that one event has occurred does not affect the probability that the other event will occur.
Dependent probability: If whether or not one event occurs does affect the probability that the other event will occur, then the two events are said to be dependent.
Since the results of the experiment are used and based on the above definitions. we should use experiement probabiity (Option B) to predict he probability of the next number showing on the top face

Answer:
∠XDQ : 41°
∠UXD: 139 °
Step-by-step explanation:
Allow me to rewrite your answer for a better understanding and please have a look at the attached photo.
A segment XD is drawn in rectangle QUAD as shown below.
What are the measures of ∠XDQ and ∠UXD ?
My answer:
As we can see in the photo, ∠ADX = 49° and ∠ADU =90°
=> ∠XDQ = ∠ADU - ∠ADX
= 90° - 49° = 41°
In the triangle ADX, we can find out the angle of ∠DXA
= 180° - ∠DAX - ∠ADX
= 180° - 90° - 49°
= 41°
=> ∠UXD = 180° - ∠DXA (Because UA is a straight line)
=180° - 41°
= 139 °

The shadow length of Kyle is 1.2 feet,if a lighthouse is 150 feet tall and cast a shadow of 30 feet. Kyle is standing next to a lighthouse and is 6 feet tall.
Step-by-step explanation:
The given is,
A lighthouse is 150 feet tall.
Cast a shadow of 30 feet.
Kyle is 6 feet tall.
Step:1
Ref the attachment,
From triangle ABC,
tan ∅ = [tex]\frac{Opp}{Adj}[/tex]......................(1)
Where, Opp = AB = 150 feet
Adj = BC = 30 feet
Equation (1) becomes,
tan ∅ = [tex]\frac{150}{30}[/tex]
= 5
∅ = [tex]tan^{-1}[/tex] 5
∅ = 78.69°
∅ is same for both ABC and PQR triangle.
From triangle PQR,
tan ∅ = [tex]\frac{Opp}{Adj}[/tex]......................(1)
Where, Opp = PQ = 6 feet
Adj = QR = x
Equation (1) becomes,
tan 78.96° = [tex]\frac{6}{x}[/tex]
5 = [tex]\frac{6}{x}[/tex]
x = [tex]\frac{6}{5}[/tex] = 1.2
Shadow length of Kyle, x = 1.2 feet
Result:
The shadow length of Kyle is 1.2 feet, if a lighthouse is 150 feet tall and cast a shadow of 30 feet. Kyle is standing next to a lighthouse and is 6 feet tall.

First term: n = 1
[tex] a_1 = 3(1 + 4) = 15 [/tex]
Second term: n = 2
[tex] a_2 = 3(2 + 4) = 18 [/tex]
Third term: n = 3
[tex] a_3 = 3(3 + 4) = 21 [/tex]
Fourth term: n = 4
[tex] a_4 = 3(4 + 4) = 24 [/tex]
Tenth term: n = 10
[tex] a_{10} = 3(10 + 4) = 42 [/tex]
The explicit formula is [tex]a_{n}[/tex] = 4 + (n - 1)3 first four terms will be 4, 7, 10, and 13 and the 10th term will be 31.
What is Arithmetic progression?The difference between every two successive terms in a sequence is the same this is known as an arithmetic progression (AP).
The arithmetic progression has wider use in mathematics for example sum of natural numbers.
Natural number = 1,2,3,4,5,6,7,8...
Now it has the same difference between any two consecutive terms d =2-1 = 3-2.
Let's say
First term = 4
Common difference = 3
Then
The nth term of the AP will be
[tex]a_{n}[/tex] = 4 + (n - 1)3
First term: n = 1
a₁ = 4
Second term: n = 2
a₂ = 7
Third term: n = 3
a₃ = 10
Fourth term: n = 4
a₄ = 13
Tenth term: n = 10
a₁₀ = 31
Hence, the explicit formula is [tex]a_{n}[/tex] = 4 + (n - 1)3 first four terms will be 4, 7, 10, and 13 and the 10th term will be 31.

Tomás ran 6 1/2 kilometers, Jackie ran 8,000 meters, Joseph ran 5.9 kilometers,
Mai Yee ran 2,790 meters. Sarita ran farther than 2 of the people in the table and slower than the others. How far could sarita have ran. Explain how you found your answer.
Answer:
5900 meters < Sarita < 6500 meters
Step-by-step explanation:
Given
Tomás = [tex]6\frac{1}{2} km[/tex]
Jackie = 8,000 m
Joseph = 5.9 km
Mai Yee = 2,790 m
Where km and m represent kilometers and meters respectively
Required
How far could Sarita have ran
First, we'll convert the distance covered by each individuals to one units (Preferably meters)
We'll need to convert distance covered by Tomás and Joseph because they're given in kilometers.
Since 1 km = 1000 m, then we have
Tomás = [tex]6\frac{1}{2} km[/tex]
Tomás = [tex]6\frac{1}{2} * 1000 m[/tex] (Convert fraction to decimal)
Tomás = [tex]6.5 * 1000 m[/tex]
Tomás = 6500 m
Joseph = 5.9 km
Joseph = 5.9 * 1000 m
Joseph = 5900 m
Now that we have the same unit all through, the next step is to list them out
Tomás = 6500 m
Jackie = 8,000 m
Joseph = 5900 m
Mai Yee = 2,790 m
Then, we rearrange in ascending order (from smallest to biggest)
Mai Yee = 2,790 m
Joseph = 5900 m
Tomás = 6500 m
Jackie = 8,000 m
The condition given in the question is that Sarita ran farther than 2 of the people in the table and slower than the other 2
This means that Sarita ran farther than the least 2 "Mai Yee and Joseph"
And at the same time Sarita covered lesser distance than the highest 2 "Tomás and Jackie"
This means that distance covered by Sarita is greater than distance covered by Joseph and less than distance covered by Tomás
Since no option is given, I'll represent the answer using inequality
Recall that
Joseph = 5900 m
Tomás = 6500 m
Sarita could have ran a distance greater than 5900 meters and less than 6500 meters
Distance covered by Sarita: 5900 < Sarita < 6500

38 degrees
52 degrees
118 degrees
142 degrees
Given:
Given that the measure of the exterior angle F is 142°
We need to determine the measure of ∠DFE
Measure of ∠DFE:
The ∠DFE and the exterior angle F are linear pairs.
Thus, the linear pair of angles add up to 180°
Hence, we have;
[tex]\angle DFE+142^{\circ}=180^{\circ}[/tex]
Subtracting both sides of the equation by 142, we get;
[tex]\angle DFE=38^{\circ}[/tex]
Hence, the measure of ∠DFE is 38°
