Answer:
[tex]12[/tex]
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form [tex]y*x=k[/tex] or [tex]y=k/x[/tex]
In this problem we have
For [tex]x=3[/tex] -----> [tex]f(x)=8[/tex]
so
Find the value of k
[tex]f(x)*x=k[/tex]
substitute the value of x and f(x)
[tex]8*3=k[/tex]
[tex]k=24[/tex]
therefore
the equation is equal to
[tex]f(x)=24/x[/tex]
For [tex]x=2[/tex] -------> substitute in the equation and find the value of f(x)
[tex]f(x)=24/2=12[/tex]

A store has a contest to guess the mass of 10,000 peanuts if a peanut has a mass of about 0.45 g what would be a reasonable guess with a mass of 10,000 peanuts
The mass of 10,000 peanuts is 4,500 g or 4.5 kg.
The question asks for a reasonable guess for the mass of 10,000 peanuts, given that each peanut has a mass of about 0.45 g. To calculate this, we simply multiply the number of peanuts by the mass of each peanut:
Mass of one peanut = 0.45 g
Number of peanuts = 10,000
Total mass = 0.45 g/peanut x 10,000 peanuts
Now we will carry out the multiplication:
Total mass = 4,500 g
Since we are dealing with a large quantity of peanuts, it is more convenient to express this mass in kilograms:
4,500 g is equivalent to 4.5 kg (since 1 kg = 1,000 g).

why is 50 + 7 x 5 = 85
"The answer is: 50 + 7 x 5 = 85 is correct due to the order of operations.
To understand why 50 + 7 x 5 equals 85, we must follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). According to this rule, multiplication and division are performed before addition and subtraction.
Let's break down the expression step by step:
1. Identify the multiplication part of the expression: 7 x 5.
2. Perform the multiplication first: 7 x 5 = 35.
3. Now, we have 50 + 35, since we have already computed 7 x 5.
4. Finally, perform the addition: 50 + 35 = 85.
So, following the order of operations, we correctly get that 50 + 7 x 5 equals 85."

a construction company is planning to bid on a building contract. the bid costs the company $1900. the probability that the bid is accepted is 1/10. if the bid is accepted, the company will make $94000 minus the cost of the bid.
a. what is the expected value in this situation?
The expected value for the construction company if they bid on the contract is $7,500, calculated by weighing the potential profit and loss with their respective probabilities.
Explanation:The question is asking us to calculate the expected value of the construction company's bid on a building contract. To find the expected value, we need to multiply each outcome by its probability and sum these amounts.
There are two possible outcomes:
The expected value (EV) is calculated as follows:
EV = (Probability of acceptance × Net profit when accepted) + (Probability of not being accepted × Loss when not accepted)
EV = (1/10 × $92,100) + (9/10 × -$1,900)
EV = $9,210 - $1,710
EV = $7,500
The expected value for the construction company if they bid on the contract is $7,500.

raise g
to the 7th power,
then subtract h
from the result
To carry out the student's request, you would first raise 'g' to the 7th power to obtain g^7, then subtract 'h' from this result to get the final expression 'g^7 - h'.
Explanation:To solve the expression mentioned by the student, you need to carry out two mathematical operations in sequence. The first operation is raising 'g' to the 7th power, which can be expressed as g^7. The second operation is subtracting 'h' from the result of the first operation. This can be represented mathematically as g^7 - h.
For example, if g equals 2 and h equals 3, then you would first calculate 2^7 which equals 128. Then you would subtract 3 from 128, yielding an answer of 125.

what is 1.375 as a fraction
Final answer:
To convert 1.375 to a fraction, express it as 1,375/1,000 and simplify by dividing by the greatest common divisor, which is 125, to get 11/8.
Explanation:
To convert the decimal 1.375 to a fraction, we will follow a few steps. First, count the number of decimal places, which in this case is three. This tells us that the denominator of the fraction should be a power of 10; specifically, 1,000. So we write 1.375 as 1,375/1,000. Next, we simplify the fraction by finding the greatest common divisor (GCD) of the numerator and the denominator. In this case, the GCD of 1,375 and 1,000 is 125. When we divide both the top and the bottom by 125, we get 11/8, which is the simplest form of the fraction.
Converting decimals to fractions involves aligning the decimal with the appropriate power of 10 in the denominator and simplifying by finding the greatest common divisor. This systematic approach ensures the representation of the decimal as a simplified fraction, such as 11/8 in the case of 1.375.
On Monday David travels m miles. On Tuesday he travels 35 more than he did on Monday. On Wednesday he travels a total of twice the distance he travelled Monday. Work out and expression of the total distance he travels during the three days
To find the total distance David travels during the three days, we add up the distances he travels on each day: m + (m + 35) + 2m = 4m + 35 miles.
Explanation:To find the total distance David travels during the three days, we need to add up the distances he travels on each day.
On Monday, David travels m miles.
On Tuesday, he travels 35 more than he did on Monday, so he travels m + 35 miles.
On Wednesday, he travels twice the distance he traveled on Monday, so he travels 2m miles.
To find the total distance, we add up the distances on all three days:
Total distance = m + (m + 35) + 2m = 4m + 35 miles.

A hacker is trying to guess someone's password. The hacker knows (somehow) that the password is 15 characters long, and that each character is either lowercase, an uppercase letter or a numerical digit. Assume that the hacker makes a random guess.
What is the probability that the hacker guesses the password on his first try? Enter your answer as a decimal or a fraction.
The probability that the hacker guesses the password correctly on the first try is 1 / 62^15.
Explanation:To calculate the probability that the hacker guesses the password correctly on the first try, we need to determine the total number of possible passwords and divide it by the total number of possible guesses.
Since the password is 15 characters long and each character can be a lowercase letter, an uppercase letter, or a numerical digit, there are 26 + 26 + 10 = 62 possible options for each character.
Therefore, the total number of possible passwords is 62^15 (62 raised to the power of 15).
The probability of the hacker guessing the password correctly on the first try is 1 divided by the total number of possible passwords.
So, the probability is 1 / 62^15. This can be left as a fraction or converted to a decimal.

For a particular event, 845 tickets were sold for a total of $4162. If students paid $4 per ticket and non students paid $6 per ticket, how many student tickets were sold?
Final answer:
Using a system of equations, we found that 454 student tickets were sold at the event.
Explanation:
To determine how many student tickets were sold for the event, we need to set up a system of equations based on the information given. Let's define x as the number of student tickets sold at $4 each, and y as the number of non-student tickets sold at $6 each.
The total number of tickets sold (student plus non-student) is given as 845 tickets:
x + y = 845
The total amount of money made from selling these tickets is $4162:
4x + 6y = 4162
Now we have a system of two equations:
x + y = 845
4x + 6y = 4162
We can solve this system by multiplying the first equation by 4:
(4)(x + y) = (4)(845)
4x + 4y = 3380
Now, we subtract this new equation from the second equation given by the total amount made to eliminate y:
4x + 6y - (4x + 4y) = 4162 - 3380
2y = 782
Dividing both sides of this equation by 2 gives us:
y = 391
Now, substitute y back into the first equation to find x:
x + 391 = 845
x = 845 - 391
x = 454
So, 454 student tickets were sold.
If u bring 10 empty bottles to the bottle shop, the bottle shop will change 10 empty bottles to 1 drink. If u bring 100 bottles to the shop. How many drinks will you get?
By bringing 100 bottles to the shop, you will receive 10 drinks.
The students question relates to a mathematical conversion problem, where empty bottles are exchanged for drinks at a bottle shop. If the conversion rate is 10 empty bottles for 1 drink, then by bringing 100 bottles, we can set up a simple division:
Number of bottles: 100
Conversion rate: 10 bottles per drink
To find out how many drinks you can get for 100 bottles, we divide the total number of bottles by the conversion rate:
Divide 100 (bottles) by 10 (bottles per drink).
100 / 10 = 10
Therefore, by bringing 100 bottles to the shop, you will receive 10 drinks.
