2 answers:

8 0

Volume cube=side^3
side=6/7
volume=(6/7)^3
remember
(a/b)^c=(a^c)/(b^c)
(6/7)^3=(6^3)/(7^3)=216/343

the volume is 216/343 cubic units

V = l* w* h
Since it's a cube length, width, and height are all the same measure.
V = (6/7)^3
V= 216/343 cubic units

A survey of 64 informed voters in Kenya revealed the following information:

Elena L [17]

Answer:

i) 12 believe neither of these things.

ii) 3 believe voting is a waste of time but don't believe that they have been abducted by space aliens.

Step-by-step explanation:

I'm going to solve these question treating these events as Venn sets.

I am going to say that:

Event A: Voting is a waste of time.

Event B: They have been abducated by space aliens.

45 believe that Voting is a waste of time

This means that $A = 45$

49 believe that they have been abducted by space aliens

This means that $B = 49$

42 believe both of these things

This means that $A \cap B = 42$

i). How many believe neither of these things?

Total of 64.

At least one is:

$A \cup B = A + B - A \cap B$

With the values we have

$A \cup B = 45 + 49 - 42 = 52$

None:

$64 - 52 = 12$

12 believe neither of these things.

ii). How many believe Voting is a waste of time but don't believe that they have been abducted by space aliens?

This is:

$A - B = A - (A \cap B) = 45 - 42 = 3$

3 believe voting is a waste of time but don't believe that they have been abducted by space aliens.

The middle person in a row is the 16th, how many persons are in the row?

Reptile [31]

Answer:

There are 31 people in the row

Step-by-step explanation:

Let us say that the number of people in the row is = x

We can also assume that the people arranged in the row are counted from one end.

The median value can be got using the formula:

median (middle person) = (n +1 )/2

where n = number of people in the row

hence, we will have

16 = (n +1)/2

n = 32 -1 =31

Therefore, there are 31 persons in the row
