Answer:

Jason is 14 year old.

Step-by-step explanation:

Given: Joe, John and Jason are each a year apart in age.

           Sum of their age is 39.

Lets assume the age of Joe be x

∴ Age of Jahn will be (x+1)

And age of Jason will be (x+2)

Now, putting up an equation for the sum of their age.

∴ x+(x+1)+(x+2)= 39

Opening the parenthesis.

⇒x+x+1+x+2= 39

⇒3x+3= 39

Subtracting both side by 3

⇒ 3x= 36

Dividing both side by 3

⇒x= \frac{36}{3}

∴ x= 12\ years

Hence, Joe is 12 year old.

Next subtituting the value of x to find age of Jason and John.

Jason= (x+2)= 12+2

∴Jason= 14 years.

John age= (x+1)= 12+1

∴ John Age= 13 years.

Hence, Jason is 14 year of age.

There are 9 people that have a conversation with each other exactly one time.
Sedbober [7]

The question is an illustration of arithmetic sequence.

<em>The number of conversation for 19 people is 171</em>

<u />

<u>(a) 9 people</u>

Total = \frac{9 \times 8}{2}

9 represents the number of people

8 represents the number of conversation each person had

2 represents the number of people having a conversation at once (i.e 2 people at once)

<u>(b) 19 people</u>

We have:

n = 19

The number of conversation is:

Total = \frac{n \times (n -1)}{2}

So, we have:

Total = \frac{19 \times (19 -1)}{2}

Total = \frac{19 \times 18}{2}

Total = 19 \times 9

Total = 171

Hence, the number of conversation for 19 people is 171

7. The amount of memory on a CD determines how many songs I can download to it.<br> Indep.<br> Dep.
galina1969 [7]

\bf \underset{dependent}{\stackrel{\textit{songs I can download}}{S(M)}}~~=~~\underset{independent}{\stackrel{\textit{how much memory I have}}{M}}

the memory is the independent, because that can vary at will, so it's independently varying at will, whilst the amount of songs are limited to how much memory there's in the CD, so the songs are dependent on the memory availability.
