Which relation is a function?

Answers

Answer 1

Answer:

A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.

On a coordinate plane, a line goes through points (0, 0), (5, 3), (10, 6) is

and, x y = 3/5

What is proportionality?

The property of having suitable proportions in terms of size, number, degree, harshness, etc.: If a defensive action against an unfair attack results in the destruction that contravenes the proportionality criterion, it may even go far beyond a justifiable defense.

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.

Here the given three points are (0, 0), (5, 3), (10, 6).

So, the equation of the line passing through the points (0, 0), (5, 3) is

y- 0/ (x-0)= (3-0)/(5-0)

y/ x = 3/5

y= 3/5x

The number of hours per week that the television is turned on is determined for each family in a sample. The mean of the data is 30 hours and the median is 26.2 hours. Twenty-four of the families in the sample turned on the television for 15 hours or less for the week. The 12th percentile of the data is 15 hours. Step 1 of 5 : Based on the given information, determine if the following statement is true or false. The 54th percentile is greater than or equal to 25 hours.

Answers

Answer:

The given statement is false

Step-by-step explanation:

Given that:

mean = 30 hours

median = 26.2 hours

In the given sample, 24 of the families turned on the television for less than 15 hours for the week.

The 53rd percentile is less than 25 hours.

The Median represents the value that equally divides the whole data into two parts. This signifies that the median is the 50th percentile of the data.

Provided that the median is 26.2 hours. So, the 54th percentile should be greater than 26.2 hours.

Thus, the given statement is false.

Elsie bought a video game for $85.00. If the store Charges 170% of what it
paid for the game, how much is the store's profit?

Answers

Answer:

$59.5

Step-by-step explanation:

170% means 170/100

To get 170% multiply 170/100 by 85.

14450/100 will be the fraction.

Simplified it is 144.5.

That is how much Elsie has to pay.

Subtract to find the profit.

144.5-85 is 59.5.

The value of the store's profit will be $35.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

Elsie bought a video game for $85.00.

And, the store Charges 170% of what it paid for the game.

Now,

Since, Elsie bought a video game for $85.00.

And, the store Charges 170% of what it paid for the game.

So, We can formulate;

Let C be the cost of the game.

⇒ 170% of C = 85

⇒ 170/100 × C = 85

⇒ C = 85 × 100 / 170

⇒ C = $50

Thus, The store's profit = $85 - $50

= $35

A state Motor Vehicle Department requires learners to pass a written test on the motor vehicle laws of the state. The exam consists of twenty true-or-false questions, of which eighteen must be answered correctly to qualify for a permit. In how many different ways can a learner who answers all the questions on the exam qualify for a permit

Answers

Answer:

211 ways

Step-by-step explanation:

Given :

Number of questions = 20

Number of correct correct questions to be answered in other to qualify should be atleast 18

Hence,

Correct questions could be either 18, 19 or 20 ;

Using combination :

nCr = n! ÷ (n-r)!r!

20C18 = 20! / (20 - 18)!18!

20C18 = (20* 19) / (2 * 1) = 190 ways

20C19 = 20! / (20-19)!19!

20C19 = 20 / 1 = 20 ways

A friend has a 83% average before the final exam for a course. That score includes everything but the final, which counts for 25% of the course grade. What is the best course grade your friend can earn? % What is the minimum score would your friend would need on the final to earn a 75% for the course? %

Answers

Answer:

[tex]\mathrm{Best\:course\:grade\:possible:\:}87.25\%,\\\mathrm{Minimum\:score\:on\:final\:to\:earn\:at\:least\:a\:75\%\:for\:the\:course:\:}51\%[/tex]

Step-by-step explanation:

Assuming the maximum score for the final is [tex]100\%[/tex], we can multiply each score by its respective course weight and add them together to give a final score. If your friend did receive this maximum score of [tex]100\%[/tex], their overall grade for the course would be:

[tex]83(1-0.25)+100(0.25)=\fbox{$87.25\%$}[/tex].

To find the minimum score they need to earn a 75% for the course, we set up the following equation:

[tex]83(1-0.25)+x(0.25)=75[/tex], where [tex]x[/tex] is the minimum score she needs.

Solving, we get:

[tex]62.25+x(0.25)=75,\\x(0.25)=12.75,\\x=\fbox{$51\%$}[/tex].
