Final answer:
The correct answer is option b. percentage, probability, and proportion, because these terms relate to ratios or fractions of a whole and can often be used interchangeably in various statistical contexts. So the correct option is b.
Explanation:
The question is asking which of the following groups contain terms that can be used interchangeably. The correct answer is b. percentage, probability, proportion. These terms can often be used interchangeably because a percentage is a way of expressing a proportion as a number out of 100, and probability is the measure of the likelihood that an event will occur, often expressed as a decimal or a proportion. None of the other options provided (a, c, and d) contain directly interchangeable terms.

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.

The weight of water is 62 1/2 lb per cubic foot. What is the weight of 1 1/9 cubic feet of water?
Final answer:
To determine the weight of 1 1/9 cubic feet of water, convert the mixed number to an improper fraction and multiply by the weight per cubic foot, resulting in approximately 77.16 pounds.
Explanation:
The student is asking to calculate the weight of 1 1/9 cubic feet of water given that the weight of water is 62 1/2 lb per cubic foot. To find the weight of the water, we multiply the volume by the weight per unit volume:
Convert 1 1/9 to an improper fraction: 1 1/9 = 10/9.
Multiply 10/9 cubic feet by 62.5 lb/ft³ (weight of water per cubic foot).
Calculate: (10/9) × 62.5 = 694.44/9 ≈ 77.16 lb.
Hence, the weight of 1 1/9 cubic feet of water is approximately 77.16 pounds.

Brandy wants to buy a digital camera that costs $300. Suppose she saves $15 each week. In how many weeks will she have enough money for the camera?
It will take Brandy 20 weeks to save enough money to buy the digital camera.
To find out how many weeks it will take for Brandy to save enough money for the camera, we can set up an equation:
Let x be the number of weeks it will take for Brandy to save enough money.
$15 * x = $300
Solving for x:
x = $300 / $15
x = 20
Therefore, it will take Brandy 20 weeks to save enough money to buy the digital camera.
what is 694 divided by 41 and what is the remainder please help thank you
We can use long division in finding the remainder.
Place the divisor which is 41, outside the long division sign, and 694 under the long division sign as shown in the diagram.
41 goes into 694 16 times.
Write the 16 on top of the long division sign.
Multiply the 16 by 41, to obtain 656
Write the 656 below the 694 as in the diagram.
Subtract 656 from 694 to obtain 38.
Since 41 is more than 38 , we cannot proceed.
Hence,
[tex]\frac{694}{41}=16\:\:Remainder\:\:38[/tex]
Therefore the remainder is 38
The quotient is 16, and the remainder is 38.
We have,
To find the quotient and remainder when dividing 694 by 41, we can perform the division and observe the results.
Now,
41 x 16 = 656
And,
694 - 656 = 38
This means,
694 divided by 41 is equal to 16 with a remainder of 38.
Therefore,
The quotient is 16, and the remainder is 38.

2.8 repeating as a fraction
Two algebraic expressions separated by an equal symbol in between them and with the same value are called equations.
Example = 2 x +4 = 12
here, 4 and 12 are constants and x is variable
A collection of constants, variables connected using one or more arithmetic operator is called an expression
Example = 4 y, 3 x+4.
Consider an equation to prove 2.8 as a repeating fraction.
Let x = 2.8 repeating
Multiply both sides of the equation by 10 to get a whole number.
10 x = 28.8 repeating
Next, we subtract the original equation from the multiplied equation to eliminate the repeating part:
10 x - x = 28.8 repeating - 2.8 repeating
9 x = 26
Now, we can solve for x by dividing both sides of the equation by 9
x = [tex]\dfrac{26}{9}[/tex]
Therefore, the decimal number 2.8 repeating can be expressed as the fraction [tex]\dfrac{26}{9}[/tex].

Ron Co. sold sweatshirts ($20) and baseball caps ($10). If total sales were $2,860 and people bought 6 times as many sweatshirts as caps, how many of each were sold?
To find the number of baseball caps and sweatshirts sold, we can set up an equation using the given information and solve for the variables. The solution shows that 22 baseball caps and 132 sweatshirts were sold.
Explanation:Let's solve this problem step by step:
Let x represent the number of baseball caps sold.Since people bought 6 times as many sweatshirts as caps, the number of sweatshirts sold would be 6x.The total sales revenue can be calculated by multiplying the price of each item by the number of items sold. So, the equation becomes: 10x + 20(6x) = 2860.Simplifying the equation gives us 10x + 120x = 2860.Combining like terms, we get 130x = 2860.Dividing both sides of the equation by 130, we find that x = 22. So, 22 baseball caps were sold.Since people bought 6 times as many sweatshirts as caps, the number of sweatshirts sold would be 6 * 22 = 132.Therefore, 22 baseball caps and 132 sweatshirts were sold.
The problem is solved by setting up equations based on the given information. Ron Co. sold 132 sweatshirts at $20 each and 22 baseball caps at $10 each to make a total of $2,860 in sales.
Explanation:To solve the problem, let's define the variables representing the number of sweatshirts and caps sold. Let's say 's' equals the number of sweatshirts and 'c' equals the number of baseball caps.
We are given two pieces of information:
The price of a sweatshirt is $20, and the price of a cap is $10. The total sales can be expressed as the sum of the sales from sweatshirts and caps, which gives us the equation 20s + 10c = 2860.
Using the information that s = 6c, we can substitute 6c for s in the total sales equation to get 20(6c) + 10c = 2860. Simplifying this equation, we get 120c + 10c = 2860, which leads to 130c = 2860. Dividing both sides by 130 gives us c = 22.
Now, we can find the number of sweatshirts sold by substituting c into the equation s = 6c. So, s = 6(22) = 132.
Therefore, Ron Co. sold 132 sweatshirts and 22 baseball caps.

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.

Determine an equation for a function that has a slope of -5 and crosses the x-axis at (3,0)
To find the equation of the line with a slope of -5 that crosses the x-axis at (3,0), use point-slope form to get y = -5x + 15, which is the required equation.
Explanation:To determine an equation for a function that has a slope of -5 and crosses the x-axis at (3,0), you can use the point-slope form of a linear equation: y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.
Here, the slope m is -5 and the point on the line is (3,0). Plugging these values into the point-slope form, we get:
y - 0 = -5(x - 3)
This simplifies to:
y = -5x + 15
This equation represents a line with a slope of -5 that crosses the x-axis at the point (3,0), meeting all the conditions given in the question.
