Final answer:

Glenn crashed in 30% of the races.

Explanation:

To find the percentage of races Glenn crashed, you can set up a proportion. A proportion is an equation that states that two ratios are equivalent. Since Glenn raced 30 times and crashed 9 times, the ratio of crashes to total races is 9 crashes out of 30 races.

You can set up the proportion as follows:
Crashes / Total Races = Percentage of Crashes / 100

Plugging in the known values gives us this:
9 / 30 = Percentage of Crashes / 100

To solve for the percentage of crashes, you multiply both sides of the equation by 100:
(9 / 30)
100 = Percentage of Crashes

Simplifying gives us:
(9/3) 10 = Percentage of Crashes

Hence, the percentage of races that Glenn crashed is 30%.

The joint probability of x1 and y2 is  P (Y₂/X₁ ) = P(Y₂ ∩ X₁ )/ P (X₁) will be 0.3.

In the joint probability of x1 and y2 is  P (Y₂/X₁ )= P(Y₂ ∩ X₁ )/ P (X₁).

Therefore:

The difference in the number of cars manufactured in August and September is 15 cars.

The difference in the number of cars manufactured in August and September can be calculated as follows:

Answer:

The mean of something is the "average"

For example, if the mean of people in the households of 7th-grade students is 4.3, this means that if you go to a random house of a 7th-grade student, you can expect around 4 people in there.

Now, for the  7th-grade students, the mean is 4.5, just a 0.2 bigger. (This means that, on average, there is more people in the 8th-grade student's households)

So Principal Coleman can infer that the amount of people in the households of  7th-grade students and 8th-grade students is almost the same, wherein the 8th-grade students there is a small chance of finding more people, but this difference is almost depreciable.

To write the expression 9xa+9xb as a product, factor out the common factor 9x to get 9x(a+b), which is the simplified product form.

The student has presented an algebraic expression: 9xa+9xb and is requesting to rewrite it as a product. To simplify this expression, we can factor out the common factor which is present in both terms. The common factor here is 9x. When we factor out 9x, we combine the terms within the parentheses.

Here is the step-by-step simplification:

A 'while loop' can be programmed with conditions to adjust a 'user value'. If 'user value' is greater than 80, 5 would be subtracted from it. If it is less than 0, 10 would be added to it. This loop continues until 'user value' does not meet either condition.

The question asks for a while loop in programming that modifies a value (user value) based on these conditions: if the user value is less than 0, it should be increased by 10 and if it's greater than 80, it should be decreased by 5. Here's a representative code for that:

while(user value < 0 || user value > 80) {

if(user value > 80) {user value -= 5; } else if(user value < 0) {user valuable += 10;}

This loop will continue to execute until the user value is not less than 0 or greater than 80.

Step-by-step explanation:

It is given that:

Louisa spins the spinner below twice.

The spinner is numbered from 1-8.

Now, on spinning the spinner twice we obtain the sample space as:

(1,1)   (1,2)....................(1,8)

(2,1)  (2,2)...................(2,8)

(3,1)   (3,2)..................(3,8)

(4,1)   (4,2)..................(4,8)

(5,1)   (5,2)..................(5,8)

(6,1)   (6,2)..................(6,8)

(7,1)   (7,2)..................(7,8)

(8,1)   (8,2)..................(8,8)

Hence, the total number of outcomes is equal to the number of elements in sample space.

Hence, the total number of possible outcomes are:

Answer:

[tex]x=44-y[/tex]

Step-by-step explanation:

Let x represents the number of glasses of iced tea .

Let y represents the number of glasses of lemonade.

Now we are given that She has only 44 cups in which to serve the drinks

Since y is the number of glasses of  lemonade out of 44 glasses

So, remaining glasses = [tex]44-y[/tex]

So, remaining glasses is for iced tea .

So, No. of iced tea glasses =  [tex]x=44-y[/tex]

Hence She can serve [tex]x=44-y[/tex] number of glasses of iced tea serve.

The expression 42 + 6x is already in its simplest form and does not have a common factor to apply the distributive property to simplify it. However, factoring out 6 would rewrite it as 6(7 + x), albeit without further simplification.

To create an equivalent expression to 42 + 6x using the distributive property, we need to factor out a common term from both parts of the expression. However, this expression does not have a common factor available in both terms. The distributive property typically comes into play when you have an expression in the form of a(b + c), where you would then distribute a to both b and c. The expression 42 + 6x is simplified as much as possible, given that one term is a constant and one term is a multiple of a variable. There is no factor that can be distributed to simplify the expression further.

However, if we wanted to factor out a number to potentially simplify the expression, we might choose to factor out 6, which would change the expression to 6(7 + x), although this does not simplify it further since the original expression is already in its simplest form.

The area of Ava's rectangular rug is 5382 square yards, calculated by multiplying the width (23 yards) and the length (234 yards).

To find the area of Ava's rectangular rug, we need to multiply its length and width:

Area = length × width

Using the given dimensions: 23 yards wide and 234 yards long:

Area = 23 × 234

First, let's perform the multiplication:

23 × 234 = 5382 square yards

Thus, the area of the rug is 5382 square yards as an improper fraction, which cannot be simplified further as a mixed number. Since the measurements are whole numbers, converting to a mixed number doesn't apply in this case.

Step-by-step explanation:

In a function flowchart, the ending terminal symbol is typically labeled 'End' or 'Stop', and it signifies the conclusion of the process represented within the flowchart.

The term used in the ending terminal symbol of a function flowchart is typically 'End' or 'Stop'. A flowchart is a type of diagram that represents an algorithm or process, showing the steps as various kinds of boxes (nodes) and their order by connecting them with arrows. The terminal symbols, which are usually represented by rounded rectangles or ovals, indicate the start and end of the process.

In designing a flowchart, the starting point is marked with a terminal symbol labeled as 'Start,' and the ending of the flowchart is similarly marked with a terminal symbol labeled as 'End' or 'Stop'. This indicates the flow of control reaching the end of the predefined process or function within the flowchart.

To find a number x between 0 and 28 with x ≡ 6 (mod 35) using Euler's theorem, we can use Euler's totient function to find the power x^24 that is congruent to 1 (mod 35). The value x = 1 satisfies the congruence, so it is a possible solution.

To use Euler's theorem to find a number x between 0 and 28 with x ≡ 6 (mod 35), we need to find the value of x that satisfies the congruence. Euler's theorem states that if a and n are coprime positive integers, then a^φ(n) ≡ 1 (mod n), where φ(n) is the Euler's totient function of n. In this case, we need to find x such that x^φ(35) ≡ 1 (mod 35). The Euler's totient function of 35 is φ(35) = φ(5) * φ(7) = 4 * 6 = 24. Therefore, we need to find x such that x^24 ≡ 1 (mod 35).

We can start by examining the powers of x modulo 35:
x  ≡ x (mod 35)
x2  ≡ x² (mod 35)
x³  ≡ x³ (mod 35)
...
x^24 ≡ 1 (mod 35)

From this, we can see that x = 1 satisfies the congruence x^24 ≡ 1 (mod 35).

Therefore, a possible value of x between 0 and 28 that satisfies x ≡ 6 (mod 35) is x = 1.
