I think of a number, double it and the result is 15​
melisa1 [442]

The number in question is 7.5

Step-by-step explanation:

15 ÷ 2 = 7.5

Why divide by 2? Because dividing by 2 is the <u>inverse</u> of multiplying by 2. To double-check our solution, just multiply 7.5 by 2... and 15!!

In a class of 20 students:
BlackZzzverrR [31]

The Venn diagram is given below. Then the number of students who have brother and sister will be 6.

<h3>What are sets?</h3>

A set is a group of clearly specified components. The number of items in a finite set is denoted by a curly bracket.

In a class of 20 students:

11 have a brother, 9 have a sister, and 6 have neither.

Then the Venn diagram will be

11 – a + a + 9 – a = 20 – 6

               20 – a = 14

                        a = 6

The Venn diagram is given below.

More about the sets link is given below.

One type of plant root splits 4 times while growing in the ground. The number of new roots after each split can be modeled by th
notsponge [240]

Answer:

All positive integers less than or equal to 4

Step-by-step explanation:

The domain of the function are all possible values which variable x can take.

Since x is the number of times the root splits, x can take values 1 (1 time splits), 2 (2 times splits), 3 (3 times splits), 4 (4 times splits).

The variable x cannot take negative values because it cannot split -2 times.

The variable x cannot take integer values greater than 4, because this type of plant root splits 4 times while growing in the ground.

Hence, the domain of the function f(x) is all positive integers less than or equal to 4.
