Answer:

C) The bars weigh 2.8oz on average.

Step-by-step explanation:

The fact that each sample's mean weight was within the 95% confidence interval suggests that the true mean weight of the chocolate bars is likely to be around 2.8 oz. The 95% confidence interval means that, in theory, if we repeated this sampling process many times, we would expect the true mean weight of the chocolate bars to fall within this interval 95% of the time. Since each sample's mean weight falls within this interval, it is reasonable to conclude that the company's claim that the bars weigh 2.8 oz on average is likely to be true.

Answer:

1) blue car 28.4 miles per gallon

2)  miles per gallon

3) Blue car

Step-by-step explanation:

In order to get the unit rate, we must divide the miles by the gallons so

Blue car: 33.5 / 1.25 = 28.4

Red car: 21.6 / 0.8 = 27

The blue car travels a greater distance on 1 gallon since 28.4 > 27

Answer:

\(\frac{16}{27}\)

Step-by-step explanation:

From the table, we notice that the total number of students is:

\(3+10+8+6=27\)

Then, along the second column of the table, we notice that the number of students who do not have a brother is:

\(10+6=16\)

So, the probability that a randomly chosen student does not have a brother is:

\(\frac{\text{number of students who do not have a brother}}{\text{total number of students}}=\frac{16}{27}\)

\( \sqrt{ \dfrac{16}{25} } + \dfrac{6}{5} \)

\( = \sqrt{ \dfrac{4 \times 4}{5 \times 5} } + \dfrac{6}{5} \)

\( = \dfrac{4}{5} + \dfrac{6}{5} \)

\( = \dfrac{4 + 6}{5} \)

\( = \dfrac{10}{5} \)

Answer:a. Cover Page: Choose a catchy title that will draw attention to your brochure, and select a picture that demonstrates the use of integers in everyday life. Some examples of catchy titles could be "The Wonderful World of Integers," "Mastering the Rules of Integers," or "Integers: A Guide to Everyday Math." For the picture, you could choose an image of a thermometer, a bank statement, or a measuring tape, all of which use integers.

b. Composition: In this section, you will describe three ways in which integers are used in everyday life. Some examples could be:

- Temperature: We use integers to measure temperature, as it is either above or below zero degrees Celsius or Fahrenheit.

- Money: We use integers to keep track of our finances, as we either have a positive or negative balance in our bank accounts.

- Distance: We use integers to measure distance, as it is either a positive or negative value depending on the direction we are traveling.

c. Song or Poem: This section can be a fun and creative way to remember the rules for each of the four operations with integers. Here are some examples of rhymes or lyrics you could use:

- Addition: When adding integers, it's easy to do. If the signs are the same, add and stay true. If the signs are different, subtract and take. The sign of the bigger number, for goodness sake!

- Subtraction: When subtracting integers, it's a breeze. Keep the first number and change the sign with ease. Add the opposite number and simplify. You'll get the answer, no need to try.

- Multiplication: When multiplying integers, it's not so hard. If the signs are the same, the answer is positive, it's true. If the signs are different, the answer is negative, it's not hard to do.

- Division: When dividing integers, it's as easy as pie. Keep the first number and change the sign, don't ask why. Multiply by the reciprocal, and simplify. You'll get the answer, it's no lie.

Answer:

We start with 4 cards. The probability of picking the 4 is 1/4. That card is put back, so we again have 4 cards. The probability of picking the 6 (the number greater than 5) is 1/4.

Therefore, the probability of picking a 4 and then a 6 is (1/4)(1/4) = 1/16.

Answer:

1/16

Step-by-step explanation:

A shipment of 1.5 pounds of moonstone crystals was divided into 6 equal bags. Each bag would weigh 0.25 pounds, which is the same as 4.0 pounds.

To solve this problem, we can use the following equation:

total weight / number of bags = weight of each bag

In this case, the total weight is 1.5 pounds and the number of bags is 6. So, the weight of each bag is:

1.5 pounds / 6 bags = 0.25 pounds per bag

Since 0.25 pounds is the same as 4.0 pounds, each bag would weigh 4.0 pounds.

Answer:

0.6796875

Step-by-step explanation:

1. We assume, that the number 9.375 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 9.375 is 100%, so we can write it down as 9.375=100%.

4. We know, that x is 7.25% of the output value, so we can write it down as x=7.25%.

5. Now we have two simple equations:

1) 9.375=100%

2) x=7.25%

where the sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

9.375/x=100%/7.25%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 7.25% of 9.375

9.375/x=100/7.25

(9.375/x)*x=(100/7.25)*x       - we multiply both sides of the equation by x

9.375=13.793103448276*x       - we divide both sides of the equation by (13.793103448276) to get x

9.375/13.793103448276=x

0.6796875=x

x=0.6796875

now we have:

7.25% of 9.375=0.6796875

The percentage of the mile 7.25% of 9.375 =0.6796875.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

We have to find percentage of the mile times range from 7.25 to 9.375.

let 9.375 represents 100% and x represents 7.25%.

Then, using proportion we can write

9.375/x=100%/7.25%

9.375/x=100/7.25

9.375 (7.25)= 100x

100x = 67.96875

x= 0.6796875

Thus, 7.25% of 9.375 =0.6796875

Step-by-step explanation:

Definition from Wikipedia

In mathematics, the greatest common divisor (GCD) of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers. For two integers x, y, the greatest common divisor of x and y is denoted as gcd(x,y) . For example, the GCD of 8 and 12 is 4, that is, gcd(8,4)=4  (https://en.wikipedia.org/wiki/Greatest_common_divisor)

Methodology to find greatest common denominator(factor) for 2 numbers

Note that even though I have listed all divisors of the higher number, you don't have to compute all divisors. You can stop figuring out the divisors once the larger number is divisible by the number that is higher than 4 but slosest to i. For example, in the case of 396, I would stop computing as soon as I found it is divisible by 6

Answer:

A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:

(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.

(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.

(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.

(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.

So, the pairings that always describe a function are:

(a person’s age in years, that same person’s height in inches)

(a person’s weight in pounds, that same person’s height in inches)

(a person’s height in centimeters, that same person’s height in inches)

These three pairings meet the criteria of a function, where each input corresponds to a unique output.

The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)

A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:

1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).

2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.

3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.

4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).

So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)
