Which term is not possible in the domain of a sequence?

Mathematics
1 answer:
ycow [4]1 year ago
8 0

The term that is not possible in the domain of a sequence is:

-5

<h3>What is the domain of a function?</h3>

The domain of a function is the set that contains all possible input values for the function. For a sequence, the domain is the set that contains all the indexed of the terms, starting at 0 and going until the nth term.

For example, suppose we have the following sequence: 3, 5, 7, ...

  • The term with index 0 is 3.
  • The term with index 1 is 5.
  • The term with index 2 is 7.

From what was explained above, which also can be visualized with the example, an index term of a sequence cannot be negative, hence the term that is not possible in the domain of a sequence is:

-5.

Which is the only negative number of the options.

Please help me I will mark brainliest! The ratio of the number of boys to the number of girls in a school is 3:4. One-third of t
Alex17521 [72]

Answer:

a) 952

b) 136

Step-by-step explanation:

<u>Ratio of b:g = 3:4, based on this we have:</u>

  • Number of boys = 3x
  • Number of girls = 4x
  • Total number of pupils = 3x+4x = 7x

<u>Number of spectacle wearers:</u>

  • 1/3*3x + 3/8*4x = x + 3/2x = 2.5x

<u>Number of those not wearing spectacles:</u>

  • 7x - 2.5x= 4.5x

<u>And this number equals to 612, then we can find the value of x:</u>

  • 4.5 x = 612
  • x= 612/4.5
  • x= 136

a) T<u>otal number of pupils:</u>

  • 7x = 7*136 = 952

b)<u> The difference in the number of boys and girls:</u>

  • 4x-3x= x = 136

At book fair, the ratio of adults to children is 7 : 3
joja [24]

The percentage of the boys at the book fair is 6%

<h3>What is a percentage?</h3>

Percentages are used in mathematics as a decimal ratio expressed in a fraction of 100. It is represented with a symbol known as %.

At a book fair, the ratio of adults to children are:

7 : 3

The total number of people at the book fair = 7 + 3 = 10

The percentage of adults are:

\mathbf{=\dfrac{7}{10}\times 100\%}

= 70% are adults

The percentage of children are:

 \mathbf{=\dfrac{3}{10}\times 100\%}

= 30% are children

However, if from the children, 4 are girls and 1 is a boy.

The total number of children at the fair  = 4 + 1 = 5

The percentage of girls are:

\mathbf{=\dfrac{4}{5} \times 30\%}

= 24%

The percentage of boys at the book fair is:

\mathbf{=\dfrac{1}{5} \times 30\%}

= 6%
