The number of students those who will most likely have their preference  to do their classwork online is 238 out of 350

According to the question statement, A teacher surveys a random group of students about their preference for doing classwork online or on paper.

17 Preferred Online and 8 Preferred on paper.

We are supposed to find the number of students who will most likely have their preference to do their classwork online.

We will be using the concept of Probability for solving this.

[tex]Probability(Event)=\frac{Favourable Outcomes}{Total Outcomes}[/tex]

Probability(Event) = Favorable Outcomes/Total Outcomes

For the survey probability of students preferring online mode of classwork is = [tex]\frac{17}{17+8} =\frac{17}{25}[/tex]

                     = [tex]0.68[/tex]

Now if we consider a group of 350 students and probability of students preferring online mode of classwork as 0.68

Let the number students preferring online mode of classwork be "x"

so  [tex]\frac{x}{350} =0.68[/tex]

or  [tex]x=0.68*350\\x =238[/tex]

Therefore, the number of students those who will most likely have their preference  to do their classwork online is 238 out of 350

where P(A) is the probability of an event “A”,  n(A) is the number of favorable outcomes and n(S) is the total number of events in the sample space.

Answer:

Step-by-step explanation:

A)

A - the population after its decrease

x - the number of years in which there has been a decrease in population

Hence,

[tex]\displaystyle\\A=30000-475x\\A+475x=30000-475x+475x\\A+475x=30000\\A+475x-A=30000-A\\475x=30000-A[/tex]

Salma can rent the car for at most 5 days while driving 275 miles

Although part of your question is missing, you might be referring to this full question: A rental car company charges $22.50 per day to rent a car and $0.10 for every mile driven. Salma wants to rent a car, knowing that: she plans to drive 275 miles. She has at most $140 to spend. Write and solve an inequality which can be used to determine, the number of days Salma can afford to rent the car while staying within her budget

The equation which addresses this problem is:

22.5x + 0.10(275) <=140

Let x be the number of days Salma can afford to rent the car

Per day rent of the car = $22.5

Cost per mile = $0.10

Plan to drive = 275 miles

Budget with Salma = $140

Equation:

22.5x + 0.10(275) <= 140

Solving the equation we get x <= 5

So, Salma can rent the car for at most 5 days while driving 275 miles

Multiplication is the opposite of division. When we multiply 4.15*3 we get 13.53.

Multiplication is one of the four basic arithmetic operations, alongside the addition, subtraction, and division. In math, multiply means the repeated addition of groups of the equal sizes.

The symbols for multiplication are cross (x), asterisk (*), and dot (.). You seem to utilize the cross a lot when you write in your notebooks. In both algebra and computer languages, the asterisk and dot are symbols (higher mathematics).

Commutative Property: According to this property, when we multiply two numbers, the result will not change depending on the order.

Associative property: It states that if we multiply three or more numbers consecutively, the order is irrelevant.

We get the dimensions of the park as length = 75 feet and width = 20 feet.

We are given that:

A yard has a perimeter of 190 feet.

Also, four times the length of the yard equals 15 times the width.

Now,

Let the length of the yard be x.

ATQ, we get the width of the yard as:

15 width = 4 x

Width = 4 / 15 x

Perimeter = 2 ( l + b )

190 = 2( x + 4 / 15 x )

95 = 19 x / 15

19 x = 95 × 15

19 x = 1425

x = 1425 / 19

x = 75 feet.

Length = 75 feet

Width = 4 / 15 x = 20 feet.

Therefore, we get the dimensions of the park as length = 75 feet and width = 20 feet.

Answer: Sometimes true

Step-by-step explanation:

This statement is sometimes true. If three planes intersect, then their intersection can be a line or a point.

I need some help since I don't comprehend what you're asking.

1. A(x) = (f(x)-f(a)) / (x-a) This average rate of change function is called A. The function f's input is represented by x minus a, while the function f's response to the input changing from a to x is represented by f(x) minus f(a).

f(5)=-2 f(9)=14 (f(5)-f(9))/(5-9)=(-2-14)/-4=4 from the table.

Over the range of x = 5 to x = 9, the average rate of change is 4.

2. g(x)=2x2+13x+1, f(x)=4x2+6x

(f/g)(x)=(4x²+6x)/(2x²+13x+1)

Using the numbers shown in the table, x = 4,5,6,7,8,9 and f(x) = 88,85,155,116,180,151,238.190,304,233,378.280

3. f(x)=x2-6x+8, g(x)=x-2, x2-6x-x+8+2=0, x2-7x+10=0 f(x)=g(x)x2-6x+8=x-2x2-6x-x+8+2=0

x₁,₂=(7⁺₋√(7²-4*10))/2=(7⁺₋3)/2 x₁=5, x₂=2

Answer: maximum amount: 75 times a year

Step-by-step explanation:

Answer:

There is nothing positive or negative about zero. Zero is just zero. It is NEITHER positive NOR negative. To the right of zero on number line are positive numbers and on the left of zero, lie the negative numbers on the number line.

Answer:

Positive numbers are greater than 0 and located to the right of 0 on a number line. Negative numbers are less than 0 and located to the left of 0 on a number line. The number zero is neither positive nor negative.

Answer: 122.5

Step-by-step explanation:

First, you have to do the distributive property for all numbers. In order to do that, you must first combine like terms.

Combining like terms are numbers that are in the parenthesis that don't have an exponent, variable, etc. In this case, you would combine 12 and -7 since they are in the same parenthesis case. 12-7 would be 5. Now, you have 7[2.5] + 3(5)]

Next, you use PEMDAS which means multiplication (parenthesis) is next which means you multiply 3 and 5. 3x5 - 15.

After that, you combine like terms again with the 2.5 and the 15 since the 15 is now out of the parenthesis. 2.5 + 15 = 17.5

Finally, you take the 7 and multiply that by 17.5 now that you have those 2 numbers left and they are in the brackets. 17.5x7 is 122.5!

However, if there is a variable to solve for, then the answer would be none/no solution because both sides are not equal.

Colton is approximately 3.9 feet apart from his  younger sister.

Pythagoras Theorem:

The statement o the Pythagoras theorem is, "if a triangle is right-angled (90 degrees), then the square of the hypotenuse is equal to the sum of the squares of the other two sides. "

Then it can be written as,

BC² = AB² + AC²​​.

Where,

​​​​AB is the base,

AC is the altitude (height), and

BC is the hypotenuse.

Given,

Colton looks around at an assembly. he notices his younger sister to his right and his older brother 7 feet ahead of him.

And Colton's brother and sister are 8 feet apart.

Now, we need to find the distance between Colton and his younger sister.

Based on the given statement, we can draw their position like the following figure.

Here B represents the position of Colton, A represents the position of his older brother and C represents the position of his younger sister.

Now, we have to use the Pythagoras Theorem in order to solve it,

=> 8² = BC² + 7²​​.

=> 64 = BC² + 49

=> 64 - 49 = BC²

=> BC² = 15

=> BC = √15

Therefore,

=> BC ≈ 3.9 feet

Therefore, the distance between Colden and his younger sister is approximately 3.9 feet.

The answer is 2.72 * 10^8 sec.

Step-by-step explanation:

Distance between Earth and Sirius is 5.062 * 10^13 miles.

Time taken = Distance travelled/speed

5.062*10^13 miles/sec/1.86*10^5 miles.

=2.72 * 10^8 sec.

So this means that the time taken to travel light from Sirius to Earth is 2.72*10^8.
