A relation is a function if _____.
there is exactly one input for each output
there is exactly one output for each input
there is more than one input for each output
there is more than one output for each input
Answer:
1 output for 1 input
Step-by-step explanation:
A relation is a function if there is exactly one output for each input.
Hence, Option 3 is true.
We know that;
A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
A relation is a function.
Hence, We get;
A relation is a function if there is exactly one output for each input.

The sum of 4 consecutive integers is 130
To find the sum of 4 consecutive integers, set up an equation and solve for the unknown numbers. The solution is the four consecutive integers 31, 32, 33, and 34.
Explanation:To find the sum of 4 consecutive integers, we can set up an equation and solve for the unknown numbers. Let's assume the first number is n.
So, the sum can be represented as n + (n+1) + (n+2) + (n+3) = 130.
Combining like terms, we get 4n + 6 = 130. Solving this equation, we find that n = 31. Therefore, the four consecutive integers are 31, 32, 33, and 34.

James surveyed people at school and asked whether they bring their lunch to school or buy their lunch at school more often. The results are shown below.
Bring lunch: 46 males, 254 females
Buy lunch: 176 males, 264 females
The events "male” and "buys lunch” are not independent because
P(buys lunch | male) = P(male) = 0.4.
P(male | buys lunch) = P(male) = 0.3.
P(buys lunch | male) = 0.3 and P(male) = 0.4.
P(male | buys lunch) = 0.4 and P(male) = 0.3.
Answer:
The correct option is 4.
Step-by-step explanation:
Given information:
Bring lunch : 46 males, 254 females
Buy lunch : 176 males, 264 females
Total number of peoples is
[tex]46+254+176+264=740[/tex]
Total number of males is
[tex]46+176=222[/tex]
The probability of male is
[tex]P(Male)=\frac{Males}{Total}=\frac{222}{740} =0.3[/tex]
Since probability of males is 0.3, therefore options A and C are incorrect.
Total number of persons who buys lunch is
[tex]176+264=440[/tex]
The probability of persons who buys lunch is
[tex]P(\text{Buys lunch})=\frac{\text{Buys lunch}}{Total}=\frac{440}{740} =\frac{22}{37}[/tex]
We need to find the probability of P(male | buys lunch).
According to the conditional probability, we get
[tex]P(\frac{A}{B})=\frac{P(A\cap B)}{P(B)}[/tex]
P(male | buys lunch)[tex]=\frac{P(\text{male }\cap \text{ buys lunch})}{P(\text{buys lunch})}[/tex]
P(male | buys lunch)[tex]=\frac{\frac{176}{740}}{\frac{22}{37}}[/tex]
P(male | buys lunch)[tex]=\frac{2}{5}=0.4[/tex]
Therefore the correct option is 4.

A metal rod is 2/3 meters long. It will be cut into pieces that are each 1/12 meters long. How many pieces will be made from the rod?
The 2/3 meter long metal rod can be divided into 8 pieces each of length 1/12 meters by dividing the total length of rod with the length of each piece.
Explanation:The subject of this question is mathematics, and it involves division. When we are given a total length and the length of each piece, we can find the number of pieces by dividing the total length by the length of each piece.
Here, the total length of the metal rod is 2/3 meters. Each piece that we want to cut is 1/12 meters long.
To find the number of pieces, we simply perform the division: (2/3)÷(1/12). When we divide fractions, we multiply the first fraction by the reciprocal of the second fraction. So this becomes (2/3)*(12/1) = 24/3 = 8 pieces.
So the metal rod can be cut into 8 pieces each 1/12 meter long.

Find three numbers between -0.55 and -0.54
in a survey 2,000 people who owned a certain type of car, 1,100 said they would buy that type of car again what percent of people surveyed were satisfied with the car
Answer:
The percentage of people surveyed that were satisfied with the car is 55%.
Step-by-step explanation:
The statement indicates that in a survey 1,100 people of 2,000 surveyed said that they would buy the car they have again and from this, you can inferred that they are satisfied with the car. So, to calculate the percentage of people surveyed that were satisfied with the car you have to divide 1,100 by 2,000 that is the total number of people surveyed and then, multiply the result by 100:
1,100/2,000=0.55*100= 55%

Describe how you regroup when you find the sum of 64+43
The required regroup of the sum of 64+43 into 60+4 and 43 into 40+3.
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches.
The sum of two numbers is given in the question as:
64 + 43
As per the given condition, the required solution would be as:
To regroup, just separate the larger numbers into smaller amounts that can be put together more easily. We frequently reorganize numbers into those that terminate in 0 because they are easier to add. For example, 64 may be divided into 60+4 and 43 into 40+3. This makes adding easy since you can first add 60 and 40, which equals 100. The smaller numerals 100+4+3=107 can then be added.
Thus, the required regroup of the sum of 64+43 into 60+4 and 43 into 40+3.

what is 5 1/6 as a rational number
The mixed number 5 1/6 can be converted into a rational number. This is done by multiplying the whole number by the denominator, adding the numerator, and then placing this value over the denominator. Thus, 5 1/6 as a rational number is 31/6.
Explanation:The number 5 1/6 is a mixed number. You can convert it to a rational number, which is a number that can be expressed as a quotient or division of two integers. A rational number is represented by 'p/q' where p and q are integers and q is not equal to 0.
To convert 5 1/6 into a rational number, you would first multiply the whole number (5) by the denominator of the fraction (6), then add the numerator of the fraction (1). This gives you the new numerator. The denominator remains 6. The calculation would look like this: (5×6 + 1)/6 = 31/6.
So, 5 1/6 as a rational number is 31/6.
