Answer:
21. x=70
22. x=15
*Not sure what the red arc is, but I found the value of x for both 21 and 22*
Step-by-step explanation:
Let's start with 21 first.
Line AB is a straight line, meaning the arc length of AB is 180 degrees. So,
(2x-30)+x=180
let's solve:
3x-30=180
3x=210
x=70
I'm not sure what the red arc is, so I can't help you there.
Next, 22.
All the arcs in a complete circle need to add up to 360 degrees, so:
4x+6x+7x+7x=360
simplify first:
24x=360
let's solve:
x=15
Again, not sure where or what the red arc is, so can't help again. I hope that the x values help.

To summarize, an outcome is a result of an experiment, a sample space is a collection of all possible outcomes, an event is a set of outcomes chosen from the sample space, and a collection is a group of events with a common property.
An experiment in probability refers to a process of observing or measuring some phenomenon, where the outcomes are uncertain. The collection of all possible outcomes from this experiment is known as the sample space. An outcome is a particular result that occurs as a result of the experiment.
Now, a set of outcomes chosen from the sample space is known as an event. An event can be as simple as a single outcome or as complex as a combination of outcomes. For example, flipping a coin and getting heads is a simple event, while flipping a coin and getting heads or rolling a dice and getting an even number is a compound event.
Finally, a collection of events is simply a group of events that share a common characteristic or property. In probability, we use collections of events to determine the likelihood of certain outcomes occurring. This allows us to make predictions about the experiment based on the available data.

The Udderly Delicious Cheese Factory produces 200 blocks of cheddar cheese and 200 blocks of Swiss cheese each day. The factory uses 5 quarts of milk to make a block of cheddar cheese and 6 quarts of milk to make a block of Swiss cheese. How many total gallons of milk does the factory use each day?
Therefore , the solution of the given problem of ratio comes out to be the Udderly Delicious Cheese Factory needs 550 gallons of milk in total.
What is a ratio?A group comprising values both variable "a" and "" that seem to be equal is found using the straightforward formula "a / b," whenever "b" might be a greater number than zero. A ratio is created by combining two ratios. The ratio , fraction could have been 1:1 if there were just one guy and three women. There are 1/4 men and 3/4 women in the group.
Here,
For cheddar cheese, multiply the quantity of blocks by 200 and the amount of milk consumed by each block by 5.
200 blocks of cheddar cheese divided by 5 quarts per block equals a total of 1000 quarts.
For Swiss cheese, the formula is as follows: 200 blocks of Swiss cheese, or 6 quarts of milk per block.
200 blocks of Swiss cheese divided by 6 quarts per block equals 1200 quarts of milk in total.
Total milk used equals the sum of the milk required to make cheddar cheese and the milk used to make Swiss cheese, or 1000 quarts plus 1200 quarts, or 2200 quarts.
We can convert quarts to gallons by dividing by 4 because there are 4 quarts in a gallon.
= 1000 quarts + 1200 quarts
= 2200 quarts
We can convert quarts to gallons by dividing by 4 because there are 4 quarts in a gallon.
=> Total gallons of milk used = 2200 quarts / 4 quarts/gallon = 550 gallons
Thus, to make 200 blocks of cheddar cheese and 200 blocks of Swiss cheese each day,
the Udderly Delicious Cheese Factory needs 550 gallons of milk in total.

A researcher was interested in comparing the resting pulse rate of people who exercise regularly and people who do not exercise regularly. Independent simple random samples of 16 people ages 30-40 who do not exercise regularly and 12 people ages 30-40 who do exercise regularly were selected and the resting pulse rate of each person was measured. The summary statistics are as follows. Do Not Exercise X1=72.3 s1=10.3 n1=16 Do Exercise X2=69.0 s2=8.9 n2=12 At the 2.5% significance level, do the data provide sufficient evidence to conclude that the mean resting pulse rate of people who do not exercise regularly is greater than the mean resting pulse rate of people who exercise regularly? Use the critical-value approach.
For a hypothesis testing by considering two samples related to rate of people who exercise and who do not exercise, the observed t-value < standard so, null hypothesis does not rejected and there is no evidence to support the claim.
We have a researcher who was interested in making a comparison of resting pulse rate of people who exercise regularly and who do not exercise regularly. There is two independent samples. In 1ˢᵗ sample, sample size, n₁= 16
Sample mean, [tex]\bar X_1[/tex] = 72.3
Standard deviations, s₁ = 10.3
In case of second sample, sample size, n₂ = 12
Sample mean, [tex] \bar X_2[/tex] = 69.0
Standard deviations, s₂ = 8.9
Level of significance = 2.5% = 0.25
Consider the null and alternative hypothesis for the test hypothesis are defined as [tex]H_0 : μ_1 =μ_2[/tex]
[tex]H_a : μ_1 >μ_2[/tex]
The test statistic : using t-test formula
[tex]t = \frac{ \bar X_1 - \bar X_2}{\sqrt{\frac{s_1^2}{n_1} +\frac{s_2^2}{n_2}}}[/tex]
[tex]= \frac{72.3- 69}{ \sqrt{ \frac {10.3^2}{16} + \frac{8.9^2}{12}}}[/tex]
= 0.91
Degree of freedom, df = n1 + n2 - 2
= 16 + 12 -2 = 26
Using the t-distribution table, the critical value for t(0.025, df = 26) is equals to the 2.06. Now, the observed t-value = 0.91 is less than 2.06 ( standard t value), so, we do not reject H₀ . Hence, no evidence to support the researcher claim.

What is limf(x) where f(x) is as shown in the table
As x approaches 2 from both sides, the values of f(x) do not approach a single value, and f(x) does not have a limit. The answer is option (d).
What is limit of a function?The calculus concept known as the limit of a function describes how a function behaves when the input variable approaches a particular value.
The phrase "lim f(x) as x approaches a" (or "limit of a function f(x) as x approaches a") describes what occurs to the output of the function when x approaches a value without actually reaching a.
The limit can be expressed in terms of two-sided, left-sided, or right-sided limits, depending on whether x approaches a from both sides, the left, or the right.
We must look at the values of f(x) as x approaches 2 in order to determine lim f(x) as x approaches 2.
Looking at the table, we can see that the values of f(x) rise from 3.99 to 4 as x approaches 2 from the left (that is, as x approaches 2 while remaining smaller than 2). The values of f(x) decline from -5 to -5.01 as x moves towards 2 from the right (that is, as x approaches 2 but staysgreater than 2).
The limit of f(x) as x approaches 2 does not exist because the values of f(x) do not approach a single integer as x approaches 2 from both sides.

Step-by-step explanation:
Given three systems of equations, you want to know the operations that transform one system to the next.
A to BEquation B2 is unchanged from equation A2, eliminating choices B and C.
Equation B1 is not a simple multiple of equation A1, eliminating choice A.
Knowing the answer is choice D, we need to find the multiplier k of equation A2 that is being added to A1. We can find that using the x-coefficients:
k(-3) +5 = -4
-3k = -9 . . . . . subtract 5
k = 3 . . . . . . . divide by -3
Then we have ...
3 × [A2] + [A1] ⇒ [B1] . . . . . . . choice D
B to CUsing the same tactics as above, we see that [C1] is unchanged from [B1], eliminating choices A and D.
[C2] is not a simple multiple of [B2], eliminating choice B.
Using the y-coefficient to find k, we have ...
k(1) +2 = 0
k = -2 . . . . . . . . subtract 2
Then we have ...
-2 × [B1] + [B2] ⇒ [C2] . . . . . . . . choice C

We found the equation multiplier, which we called "k", by looking at an arbitrary variable coefficient. Which of the numbers we use in this process is immaterial. That is, we could use either coefficient, or the right-side constant, and we would get the same result.

a) A 2*2 area model would not work to multiply (x + 3)(2x⁴ − 3x³ − 2x² − 4x − 1) because this expression has 5 terms, and a 2*2 area model can only accommodate 4 smaller areas (b) The area model for (x + 3)(2x⁴ − 3x³ − 2x² − 4x − 1) with the correct lengths and widths labeled has been attached below. (c) The final total area is 2x² - 10x - 15.
What is an area model?An area model is a way to visualize multiplication by breaking up the larger rectangle into smaller rectangles whose areas represent the products of the terms being multiplied. To determine the correct rows and columns for the area model, we count the number of terms in each factor and use that as a guide. For example, if one factor has 3 terms and the other has 4 terms, we would use a 3x⁴ area model, with 3 rows and 4 columns.
a) A 2*2 area model would not work to multiply (x + 3)(2x⁴ − 3x³ − 2x² − 4x − 1) because this expression has 5 terms, and a 2*2 area model can only accommodate 4 smaller areas.
b) The area model for (x + 3)(2x⁴ − 3x³ − 2x² − 4x − 1) with the correct lengths and widths labeled has been attached below.
2x⁴ − 3x³ − 2x² − 4x − 1
+---------------------------------------
x | 2x⁵ -3x⁴ -2x³ -4x² -x
|
3 | 6x⁴ -9x³ -6x² -12x -3
+---------------------------------------
c) To find the total area of a rectangle with length (x + 8) and width (x − 5), we can use an area model with 2 rows and 2 columns. The length (x + 8) corresponds to one dimension of the rectangle, while the width (x − 5) corresponds to the other dimension. The area of each smaller rectangle in the model represents the product of one term from each factor.
x + 8 x - 5
+--------------------
x | x² + 8x x² - 5x
|
-5 | -5x + -40 -5x + 25
+--------------------
The final total area can be found by adding up the areas of the smaller rectangles:
Total area = x² + 8x + x² - 5x - 5x - 40 + 25
= 2x² - 10x - 15

on tuesday, a local gas station had 135 135135 customers. the table above summarizes whether or not the customers on tuesday purchased gasoline, a beverage, both, or neither. based on the data in the table, what is the probability that a gas station customer selected at random on that day did not purchase gasoline?
The probability that a randomly selected gas station customer on that day did not purchase gasoline is 10/27.
We know that, the probability of any event is the ratio of the number of favorable case to that event to the total number of cases.
The total number of customers in that Gas Station on that day = 135
According to the data table,
Number of customers did not purchase gas but purchased beverage = 35
Number of customers neither purchase gas nor beverage = 15
So total number of customers did not purchase gas = 35 + 15 = 50
Here number of favorable cases = 50
So the probability that a randomly selected gas station customer on that day did not purchase gasoline = 50/135 = 10/27.

Consider the queueing model of the bank in Conceptual Problem 6.9. Suppose the arrival rate is 18 per hour, the mean service time is 10 minutes, and the lobby can handle 15 customers at one time. How many tellers should be used if the aim is to keep the mean queueing time to less than 5 minutes
The number of tellers that should be used if the aim is to keep the mean queuing time to less than 5 minutes is 3.
To determine the number of tellers follow these steps:
1. Arrival rate (λ) = 18 customers per hour
2. Mean service time (μ) = 10 minutes per customer = 1/6 customer per minute
3. Lobby capacity = 15 customers
4. Target mean queuing time = 5 minutes
Now, calculate the service rate and find the number of tellers needed to achieve the target mean queueing time.
Step 1: Convert arrival rate to customers per minute: λ = 18/60 = 0.3 customers per minute
Step 2: Calculate the service rate per teller: 1/μ = 1/(1/6) = 6 customers per hour = 0.1 customers per minute
Step 3: Determine the number of tellers (n) needed to achieve the target queuing time:
Using the formula:
n > λ / (μ * (Wq_target + 1/μ))
Here, Wq_target is the target mean queuing time in minutes.
n > 0.3 / (0.1 * (5/60 + 1/(6/60)))
After solving the inequality, we get:
n > 2.4
Since the number of tellers must be a whole number, therefore, at least 3 tellers should be used in the queueing model of the bank to keep the mean queueing time to less than 5 minutes.

Falcons; they have a larger median value of 22.5 inches
Pelicans; they have a larger median value of 22 inches
Falcons; they have a larger mean value of about 22 inches
Pelicans; they have a larger mean value of about 23 inches
The team that has the largest overall size hat for their players is the Falcons; they have a larger mean value of about 22 inches
How to solveIn order to determine the average hat size per team, it is necessary to sum up each player's measurements and divide by the total number of players.
For the Pelicans: The combined sum equals 344.5, which results from adding up values such as 21.5, 25, 22, 24, and so on. With a team membership of 15 people, their mean measures out to approximately 22.97 inches.
The Falcon's equivalent calculation yields a total of 330 attained from summing head sizes, including those measuring 20, 23.5, 21, etc., with an equal number of members, coming close to an average measure of 22 inches thick.
As a result, comparisons between both teams reveal that the Falcons possess the larger collective hat size averages at roughly 22 inches in thickness.

Two friends live 7 miles apart. One Saturday, the two friends set out on their bikes at 8am and started riding towards each other. One rides at 0. 2 miles per minute, and the other rides at 0. 15 miles per minute. At what time will the two friends meet?
The time when the two friends will meet is 8:20 am.
We can start by finding the combined speed at which the two friends are approaching each other. This can be found by adding their individual speeds:
0.2 miles/minute + 0.15 miles/minute = 0.35 miles/minute
This means that the friends are approaching each other at a combined speed of 0.35 miles/minute.
To find out how long it will take for the friends to meet, we can use the formula:
time = distance / speed
In this case, the distance is 7 miles (since they are 7 miles apart) and the combined speed is 0.35 miles/minute. So we can solve for time as follows:
time = 7 miles / 0.35 miles/minute = 20 minutes
Therefore, it will take the two friends 20 minutes to meet each other while biking towards each other.
Since they started biking at 8am and it took them 20 minutes to meet, they will meet at 8:20am.

1. x = 61°; y = 61° 2. x = 12; y = 7 3. x = 5; y = 13
4. x = 97°; 5. x = 6 6. x = 9
How to Find the Values of x and y Using Theorems?1. x = 61° [based on the vertical angles theorem]
y = 61° [based on the corresponding angles theorem]
2. 8x = 96 [based on the corresponding angles theorem]
x = 96/8
x = 12
8x = 11y + 19 [based on the vertical angles theorem]
Plug in the value of x:
8(12) = 11y + 19
96 = 11y + 19
96 - 19 = 11y
77 = 11y
77/11 = y
y = 7
3. 8x + 2 = 42 [based on the alternate interior angles theorem]
8x = 42 - 2
8x = 40
x = 40/8
x = 5
8x + 2 + [6(2y - 3)] = 180 [based on the linear angles theorem]
8(5) + 2 + 12y - 18 = 180
40 + 12y - 16 = 180
24 + 12y = 180
12y = 180 - 24
12y = 156
y = 156/12
y = 13
4. x = 97° [corresponding angles theorem]
5. 8x = 4x + 24 [based on the alternate exterior angles theorem]
8x - 4x = 24
4x = 24
x = 6
6. 11x + 33 + 6x - 6 = 180
17x + 27 = 180
17x = 180 - 27
17x = 153
x = 9

Question 3
Terry has a new retirement account. He plans to make deposits of $4,750 per year for the next 40 years. He expects the account to earn 9.1% for the first 25 years, 6.9% for the next ten years, and then 4.5% for the last five years. How much will have have at the end of the forty years based on these assumptions?
With an initial investment of $19,675.13 and yearly deposits of $3,000 at an interest rate of 9.25%, the account will be worth around $336,312.91 in 25 years.
what is unitary method ?The unitary approach is a strategy for problem-solving in which the value of one piece of a quantity is determined, then the cost of an unique number of units associated with that quantity is subsequently determined using that value. In other words, it's a method of proportional used to resolve issues where one unit's value is known but another's value is needed. The unitary method's fundamental premise is to establish a percentage between two quantities, one of which is stated in the form of one unit and the other in terms of a greater number of units.
given
In the following ten years, we have:
P = $4,750 r = 6.9% = 0.069
n = 10
[tex]FV2 = $4,750 * ((1 + 0.069)^10 - 1) / 0.069[/tex]
= $74,894.87
In the previous five years, we have:
P = $4,750
r = 4.5% = 0.045
n = 5
= $127,756.44
Lastly, we can combine the two figures to determine the account's entire future value:
FV is $208,556.47 + $127,756.44 = $336,312.91 (annual deposits + initial investment).
With an initial investment of $19,675.13 and yearly deposits of $3,000 at an interest rate of 9.25%, the account will be worth around $336,312.91 in 25 years.

Factor.
2d² + 11d + 9
Answer:
(d + 1) (2d + 9)
Step-by-step explanation:
2d² + 11d + 9
First, we rewrite 11d as 2d + 9d, we have the equation:
2d² + 2d + 9d + 9
We group them, so the equation will be
(2d² + 2d) + (9d + 9)
Factor out the GCF of each group
2d (d + 1) + 9 (d + 1)
Factor the polynomial by factoring out the greatest common factor, d+1
(d + 1) (2d + 9)
So, the answer is (d + 1) (2d + 9)
In each graphic, the triangle was dilated to create the image triangle. Determine which scale factor was used for each dilation by dragging the correct scale factor to each graph.

The scale factor applied for each dilation are-
For ΔABC - scale factor = 2For ΔDEF - scale factor = 1/2For ΔGHJ - scale factor = 1/3For ΔKML - scale factor = 3Explain about the term scale factor :The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).
The form will be smaller if the scaling factor is a fraction. Reduction is the term for this. Therefore, a scaling factor of 1/2 suggests that the fresh shape is equal to half of the old shape.
Part a: For ΔABC
Length AB = 2 units
Length A'B' = 4 units
A'B' = 2 *AB
Hence, For ΔABC - scale factor = 2
Part b: For ΔDEF -
Length DF = 2 units
Length D'F' = 1 units
D'F' = 1/2 DF
Hence, For ΔDEF - scale factor = 1/2
Part c: For ΔGHJ
Length GH = 3 units
Length G'H' = 1 units
G'H' = 1/3 GH
Hence, For ΔGHJ - scale factor = 1/3
Part d: For ΔKML -
Length KM = 2 units
Length K'M' = 6 units
K'M' = 3*KM
Hence, For ΔKML - scale factor = 3
