Answer:

  at least 1 and less than 14

Step-by-step explanation:

The square bracket on the left means that 1 is included in the interval. The value will be 1 or more. The round bracket on the right means that 14 is not included in the interval. The value will be less than 14.

The values of interest are in the interval between 1 and 14, including 1, but not 14. We can describe it as "<em>at least one but less than fourteen.</em>"

_____

<em>Comment on conjunctions</em>

In logical expressions, the words "but" and "and" have the same meaning.

A tin of biscuits contains shortbread and choc-chip biscuits in the ratio 2:3 . The tin contains 80 biscuits. How many short-bre
Aleksandr [31]

Answer:

32

Step-by-step explanation:

There are 80 biscuits inside the tin.

Also, they said that those biscuits are in the ratio

Short bread    :      Choc - chip

          2          :        3

Altogether there are 5 shares ( 2 + 3)

And now you can divide 80 by 5 to find how many biscuits contain per a share.

80 ÷ 5 = 16

In the question, they asked us to to find the number of short biscuits inside the tin.

Let us find that.

There are 2 shares for short bread biscuits.

So,

Number of short biscuits ⇒ 2 × 16

                                         ⇒ 32

Hope this helps you :-)

ExtremeBDS [4]

Answer:

3rd option

Step-by-step explanation:

(\frac{f}{g} )(x)

= \frac{f(x)}{g(x)}

= \frac{2x^2-5x-3}{2x^2+5x+2} ← factorise numerator and denominator

= \frac{(x-3)(2x+1)}{(x+2)(2x+1)} ← cancel (2x + 1) on numerator/ denominator

= \frac{x-3}{x+2}
