Answer:

To calculate 2 3/4 of 500 grams, follow these steps:

1. Convert the mixed number to an improper fraction:

2 3/4 = (2 x 4 + 3)/4 = 11/4

2. Multiply the improper fraction by 500:

11/4 x 500 = (11 x 500)/4 = 2,750/4

3. Simplify the fraction by dividing the numerator and denominator by their greatest common factor, which is 2:

2,750/4 = (2 x 1,375)/(2 x 2) = 1,375/2

Therefore, 2 3/4 of 500 grams is equal to 1,375/2 grams or 687.5 grams.

Answer: the required sample size =1658944

Step-by-step explanation:

When the prior population proportion for the study is unknown , then the formula for sample size is \(Sample \ size = 0.25(\dfrac{z^*}{Margin\ of \ error})^2\)

z-value for 99% confidence = 2.576

\(Sample \ size = 0.25(\dfrac{2.576}{0.001})^2\\\\=0.25(2576)^2\\\\=1658944\)

Hence, the required sample size =1658944

The expected winnings over the time are -73/9.

The term "outcome" refers to a potential outcome in the field of probability theory. [1] A specific experiment can have any number of outcomes, and they are all distinct and unrelated to one another (only one outcome will occur on each trial of the experiment). A sample space is made up of every scenario that could happen during an experiment.

The four possible outcomes for the experiment in which we flip a coin twice are (H, T), (T, H), (T, T), and (H, H), where "H" denotes "heads" and "T" denotes "tails." Events, which are formally referred to as "groups" of outcomes, should not be confused with outcomes. When "at least one "heads"" is flipped, we can characterize an event as taking place.

(2, 5), (5, 2), (1, 6), (6, 1), (3, 4), (4,3), (6, 5), (5, 6)

These are the possible outcomes to win $25 out of 36 outcomes.

=(8/36)(25)

For the remaining 28 outcomes, we lose $15

=(28/36)(-15)

=((8×25)/36)-((15×28)/36)

=(50/9)-(105/9)

= -55/9

For each play $2 is the pay,

So, (-55/9)-2=-73/9

Therefore, the expected winnings over the time are -73/9

Answer:

  15 in, 30 in, 30 in

Step-by-step explanation:

Let x represent the length of the smallest side. Then the other two sides are (x+15) and (2x). The perimeter is the sum of the side lengths:

  x +(x +15) +2x = 75

  4x = 60

  x = 15 . . . . . . . . . . . shortest side

  (x+15) = 30 . . . . . . second side

  (2x) = 30 . . . . . . . third side

The shortest side is 15 inches, the second side is 30 inches, and the third side is 30 inches.

The equation that Sharon can use to find c is

                               300(c-0.20)= 180

The average amount the cable company charges per channel was $0.8.

An equation is a mathematical statement which can be constructed by two expressions connected by an sign which is called equal '=' sign to find out the value of unknown variable.

For example, 3x – 11 = 16 is an equation. Solving this equation, we get the value of x as x = 9.

Sharon wants to switch from cable to satellite TV. She calls Great Vista Satellite to get a quote. After looking at her cable bill, the salesperson explains that they can provide the same 300 channels Sharon has for $0.20 less per channel. If she switches, her monthly satellite bill will come to $180.

Let us take in previous case the bill was $c for one channel.

so for 300 channels it will be $300c.

If Sharon has for $0.20 less per channel

Then price per channel will be $(c-0.20)

For 300 channels it will be $300(c-0.20)

It equals to $180

so equating both values we get the  equation and the equation will be,

          300(c-0.20)= 180

The equation that Sharon can use to find c is

                               300(c-0.20)= 180

To find the average amount we will solve c from the equation.

                                  300(c-0.20)= 180

                                ⇒ c-0.20 = 180/300 [ dividing both sides by 300 we get]

                                 ⇒ c- 0.20 =0.6

                                  ⇒ c= 0.8 [ Adding both sides 0.20 we get]

 Hence, The average amount the cable company charges per channel was $0.8.

Out of the 400 surveyed students, 327 were either seniors or commuters.

To find the number of students who were either seniors or commuters out of the 400 surveyed students, we need to add the number of seniors and the number of commuters while avoiding double-counting those who fall into both categories.

According to the information given:

There were 262 seniors.

There were 215 commuters.

150 of the seniors were also commuters.

To avoid double-counting, we need to subtract the number of seniors who were also commuters from the total count of seniors and commuters.

Seniors or commuters = Total seniors + Total commuters - Seniors who are also commuters

= 262 + 215 - 150

= 327

Therefore, out of the 400 surveyed students, 327 were either seniors or commuters.

It's important to note that in this calculation, we accounted for the overlap between seniors and commuters (150 students who were both seniors and commuters) to avoid counting them twice.

This ensures an accurate count of the students who fall into either category.

The probability that a marble drawn is red is 0.4286, marble is odd-numbered is 0.5, and marble drawn is red or blue is 1.

There are 6 red marbles and 8 blue marbles, for a total of 14 marbles. The probability of drawing a red marble is the number of red marbles divided by the total number of marbles

P(Red) = 6/14 = 0.4286 (rounded to four decimal places)

There are 6 red marbles and 8 blue marbles, and 7 of them are odd-numbered (1, 3, 5, 7). The probability of drawing an odd-numbered marble is the number of odd-numbered marbles divided by the total number of marbles:

P(Odd) = 7/14 = 0.5 (rounded to four decimal places)

The probability of drawing a red or blue marble is the sum of the probabilities of drawing a red marble and a blue marble:

P(Red or Blue) = P(Red) + P(Blue)

To find P(Blue), we note that there are 8 blue marbles and 14 total marbles. Therefore,

P(Blue) = 8/14 = 0.5714 (rounded to four decimal places)

Now we can find P(Red or Blue)

P(Red or Blue) = P(Red) + P(Blue) = 6/14 + 8/14 = 14/14 = 1

What's periodic diffrence ?

Periodic difference refers to the difference in a particular volume ( similar as cost or income) between two different options over the course of a time. It's calculated by multiplying the yearly or per- unit difference by 12 ( the number of months in a time). The periodic difference is a useful metric for comparing the long- term costs or benefits of different options over a time.

The difference in cost per cargo between Brand C and Brand D is$0.58-$0.44 = $0.14.

Multiplying this by the number of loads per month gives

0.14/ cargo x 10 loads/ month = $1.40/ month.

The periodic difference in cost would be

1.40/ month x 12 months/ time = $16.80/ time.

thus, the answer is ( a) $16.80.

Step-by-step explanation:

The actual and estimated distances are

AB = √17 = 4.1

GH = √32 = 5.7

From the question, we have the following parameters that can be used in our computation:

A = (0, 4) and B = (1, 0)

The distance is then calculated as

AB = √[(4 - 0)² + (1 - 0)²]

Evaluate

AB = √17

When estimated, we have

AB = 4.1

Also, we have

G = (0, 0) and H = (4, -4)

So, we have

GH = √[(4 - 0)² + (4 - 0)²]

Evaluate

GH = √32

Using the Chain Rule, we have: dy/dx = f'(g(x)) * g'(x) = 1 * 1 = 1.The derivative of y with respect to x is 1.

When we compose a function, it may be possible to write it in a variety of different ways. Differentiating such functions can result in different derivatives, but the Chain Rule indicates that the derivatives of the compositions should be the same regardless of how the function is written, if the function is continuous and differentiable.For instance, consider the function f(x) = sin(x²). It can be written as f(g(x)) where g(x) = x² and f(x) = sin(x). Furthermore, it can be written as f(h(x)) where h(x) = x² and f(x) = sin(x). These are both compositions of functions, but they are different compositions that lead to different derivatives.However, if the function is a composite of differentiable functions, the Chain Rule tells us that the derivative of a composite function is the derivative of the outer function multiplied by the derivative of the inner function.

To find dy/dx if y = x using the Chain Rule with y as a composite of the following functions, we must first rewrite y as a composite function: y = f(g(x)) where g(x) = x and f(x) = x. This composite function can be written in a variety of different ways, such as y = f(h(x)) where h(x) = x and f(x) = x, or y = f(k(x)) where k(x) = x and f(x) = x. However, regardless of how we write it, the Chain Rule tells us that the derivative of y is equal to the derivative of the outer function (f(x) = x) multiplied by the derivative of the inner function (g(x) = x).

Answer: She started with 28 pieces of candy.

Step-by-step explanation: In the beginning of the question it says that heather took 8 pieces. Then she divided the rest evenly amongst her 5 kids. Each received 4, so that make the equation 8+(5x4) which gives us 8+(20). Or 8+20 which is 28.

Answer:

She started with 28 candies.

Explanation:

Let the total amount of candies be c

Build equation:

→ remaining: c - 8

→ each gets: (c - 8)/5

Here given each gets 4 candies

So,

(c - 8)/5 = 4

c - 8 = 5(4)

c - 8 = 20

c = 20 + 8

Answer:

  x = 2/3

Step-by-step explanation:

The approach usually recommended for almost any problem involving fractions is to "clear fractions" first. Here, that means multiplying both sides of the equation by 2x (the least common denominator). After that, divide both sides by the coefficient of x.

  \(\dfrac{2}{x}=\dfrac{6}{2}\qquad\text{given}\\\\\dfrac{(2x)(2)}{x}=\dfrac{(2x)(6)}{2}\qquad\text{multiply by $2x$}\\\\4=6x\qquad\text{simplify}\\\\\dfrac{4}{6}=x\qquad\text{divide by 6}\\\\\boxed{x=\dfrac{2}{3}}\qquad\text{reduce the fraction}\)

__

After you have done this a few times, you recognize that the process involves multiplying the original equation by 2x/6 = x/3. This is x times the reciprocal of the constant term on the right. You can "cut to the chase" and do multiplication of both sides by x/3 as your first step:

  \(\dfrac{2}{x}\cdot\dfrac{x}{3}=\dfrac{6}{2}\cdot\dfrac{x}{3}\qquad\text{multiply the given equation by $\dfrac{x}{3}$}\\\\\dfrac{2}{3}=x\qquad\text{simplify}\)

Answer:

x-intercept: 4

y-intercept: 2

Step-by-step explanation:

finding the x-intercept:

first, substitute y = 0.

2x + 4 x 0 = 8

then, remove the 0.

2x + 0 = 8

then, divide both sides. 2x = 8

so, x = 4.

finding the y-intercept:

first, substitute x = 0.

then, solve.

2 x 0 + 4y = 8

so, y = 2.

The solution to the system of equations is (x, y) = (-261/47, 44/47) as an ordered pair.

To solve the given system of equations:

Equation 1: 8x + 9y = -36

Equation 2: x + 7y = 1

We can use the method of substitution or elimination to find the values of x and y. Let's use the method of substitution:

From Equation 2, we can solve for x:

x = 1 - 7y

Substituting this value of x into Equation 1:

8(1 - 7y) + 9y = -36

8 - 56y + 9y = -36

-47y = -44

y = 44/47

Substituting the value of y back into Equation 2 to find x:

x + 7(44/47) = 1

x + 308/47 = 1

x = 1 - 308/47

x = (47 - 308)/47

x = -261/47

Therefore, as an ordered pair, the solution to the system of equations is (x, y) = (-261/47, 44/47).
