We are given that:
p is greater than 25, this means that p>25
p ∈ ]25,∞[ ...........> interval I

q is less than 35, this means that q<35
q ∈ ]-∞,35[ ...........> interval II

The given condition <span>p ∧ q is true means that (p and q) is true. In other word, their intersection is true.
Therefore, the final result would be the intersection between the two intervals (interval I and interval II)

Bases on the above, the final answer would be:
</span>]-∞,35[  ∧ ]25,∞[  which is ]25,35[<span>

</span>

<h2>Answer:</h2>

The correct options are:

                               28 , 32

<h2>Step-by-step explanation:</h2>

We are given a conditional statement p as:

              p: A number is greater than 25.

This is the collection of all the real numbers which are greater than 25.

i.e. the set p is given by:

         p=  (25,∞)

Similarly,

The conditional statement q is given by:

                   q: A number is less than 35.

This is the collection of all the real numbers which are less than 35.

i.e. the set q is given by:

         p=  (-∞,35)

Now we are asked to find:

                        p∧q which is the intersection if the elements of the two set.

Hence,

p∧q=  (25,35)

is the collection of elements which are greater than 25 and less than 35.

1)

              24

as we see that  24∉ (25,35)

Hence, option: 1 is incorrect.

2)

                 28

as we see that:   28∈ (25,35)

Hence, option: 2 is correct.

3)  

                       32

Similarly  32 ∈ (25,35)

Hence, option: 3 is correct.

4)

                    36

Here   36 ∉ (25,35)

Hence,   option: 4 is incorrect.

5)

                   40

Again   40 ∉ (25,35)

Hence, option: 5 is correct.

You have 10 cups of a cleaning solution that is 10% white vinegar and 90% water. You want the mixture to be 50% white vinegar an
lisabon 2012 [21]
Let
x-->volume of white vinegar you need to add to the mixture (measured in cups)
<span>then
the amount of the pure vinegar in the mixture will be -----> (10*0.1 + x) cups
t</span>he volume of liquid will be ---------> 10 + x
the concentration equation is-------> [(10*0.1 + x)/(10+x)]=0.50<span>multiply both sides by (10+x) and then simplify

</span>(10*0.1 + x)=(10+x)*0.50-----------> 1+x=5+0.50x-------> 0.50x=4
x=8

the answer is 
<span>you need to add 8 of a cup of the pure vinegar to the mixture</span>
