Michael uses lemonade concentrate and water to make lemonade for the family. The ratio of cups of lemonade
concentrate to cups of water is 1:3. If he made 32 cups of lemonade for the family, how many cups of
concentrate did he need?

Answers

Answer:

8 cups

Step-by-step explanation:

Given that the ratio is 1:3

concentrate =1

water=3

the total =3+1=4

using the part to all method

1/4=x/32

cross multiply

4x=32

divide both sides by 4 we have

x=32/4

x=8

Therefore the amount of concentrate is 8 cups

M Is the midpoint of AB. If AB = 3x +14, and AM = 2x-1, find x and MB.​

Answers

Answers:

x = 16

MB = 31

==================================================

Work Shown:

M is the midpoint of AB

This means AM is half as long as AB and AM = MB

Put another way, AB is twice as long as AM

AB = 2*AM

3x+14 = 2*(2x-1)

3x+14 = 4x-2

14+2 = 4x-3x

16 = x

x = 16

AM = MB

MB = AM

MB = 2x-1

MB = 2*16-1

MB = 32-1

MB = 31

Answers

Correct question is;

Tanya walked for 17 minutes from her home to a friend that lives 1.5 kilometers away. D(t) models Tanyas remaining distance to walk in kilometers, t minutes since she left home. What number type is more appropriate for the domain of d?

Answer:

0 ≤ t ≤ 17 ; (0, 17)

Step-by-step explanation:

We are told that she has walked for 17 minutes from her home to a friend that lives 1.5 kilometers away.

Now, we want to find the domain of numbers that shows her remaining distance.

Since she spent 17 minutes, then it means in modeling remaining distance it could be from 0 to 17 minutes as the case may be. Thus, the domain can be written as;

0 ≤ t ≤ 17 ; (0, 17)

Answer:

0≤t≤17, real numbers

You are given a set of data with a mean of 50 and standard deviation of 8. Using the normal curve, give an example of an outlier and explain why.

Answers

Answer:

Anything less than 26, and greater than 74.

Step-by-step explanation:

In normal distribution, the outlier is more than e ≈ 2.72 standard deviations above quartile 3, and e standard deviations below quartile 1. These quartiles are divisions that make up what is known as the innerquartile range(IQR). Which defines the variability of a data set given by IQR = Q3-Q1.

Given that the mean of this data is 50, and the standard deviation is 8.

Our outliers are anything less than 26, and anything greater than 74. Since outliers are anything outside the mean plus and minus the standard deviation times 3

One of the wagers in roulette is to bet that the ball will stop on a number that is a multiple of 3. (Both 0 and 00 are not included.) If the ball stops on such a number, the player wins double the amount bet. If a player bets $5, compute the player's expectation. (Round your answer to two decimal places.)

Answers

Answer:

The player's expectation is a loss of 20 cents.

Step-by-step explanation:

In a game of roulette, there are 38 slots where the ball can stop.

The slots are numbered as follows: {0, 00, 1, 2, 3 ..., 36}.

So, N = 38.

The slots which are multiples of 3 are:

S = {3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33 and 36}

So, n (S) = 12.

Let X = the ball stops on a number that is a multiple of 3

The probability that the ball stops on a number that is a multiple of 3 is:

[tex]P(X)=\frac{n (S)}{N}=\frac{12}{38}=0.32[/tex]

It s provided that the player wins double the amount bet if the ball stops on a number that is a multiple of 3.

Compute the player's expectation as follows:

[tex]E(X)=\sum X\cdot P(X)[/tex]

        [tex]=(\$10\times 0.32)+(-\$5\times (1-0.32))\\\\=\$3.20-\$3.40\\\\=-\$0.20[/tex]

Thus, the player's expectation is a loss of 20 cents.

Ava earns $3,000 in 1 month at her job. How much will Ava earn in 20 months?
Use the drop-down boxes to show how to solve the problem.

Ava Finds _________. Ava will earn __________ in 20 months.

Answers

Answer:

$60,000

Step-by-step explanation:

If Ava earns at a constant rate of $3,000 for 1 month, then just multiply $3,000 by how many months she works.

3,000 x 20 = 60,000

If Ava earns $3,000 in one month, she will earn $60,000 in 20 months.

Based on the amount that she earns per month, we can find out that in 20 months, Ava will earn $60,000.

Ava earns $3,000 per month she works.

If she worked for 20 months, that monthly amount would be multiplied by 20 as shown below:

= Salary per month x number of months worked

Solving would give:

= 3,000 x 20

= $60,000

In conclusion, Ava would make $60,000 in 20 months.

How can we tell the computer both what to put on the web page, and how to organize it?

Prompt: In your own words, how does HTML help solve the problem of telling the computer what a web page looks like, not just what content is on it?

Answers

Answer:

Step-by-step explanation:

The way we do this is through coding. HTML is the go-to programming language that are basically instructions given to the computer explaining what content will go on the web page as well as how it will be organized. HTML tends to go hand-in-hand with CSS, another programming language that focuses on how the content will look, such as color, borders, shading, etc. All with the idea of making the content look nicer. Without these programming languages, it would be impossible for individuals to make webpages.
