Your friend says the sum of two linear expressions is always linear expressions. Is your friend correct? Explain.

ra1l [238]

Yes, since adding two like variables will always result in the same variable.(i.e. x+x=2x not x^2). Any expression with the highest variable being to the power of 1 (or just x) is ALWAYS a linear expression.

What is the probability that a stamp chosen at random is a commemorative or a special delivery stamp?

Ksivusya [100]

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given that

$P(\text{ getting a commemorative stamp})=0.16$

and

$P(\text{getting a special delivery stamp})=0.18$

So, we need to find,

$P(\text{getting either a commemorative or a special delivery stamp})\\=P(\text{getting a commemorative stamp})+P({\text{ getting a special delivery stamp})$

(∵they are independent events .)

$P(\text{getting either a commemorative or a special delivery stamp})\\=0.16+0.18\\=0.34$

So, option 'D' is correct.

Suppose you have a group of 8 male and 4 female volunteers. how many ways are there to choose 6 of these volunteers for a treatm

Kay [80]

Since volunteers can be of any sexe (no precision given in your problem), then we can consider the question as how many group of 6 we can make with 12 persons:
It's a combination of 6 chosen among 12

¹²C₆ = (12!)/(6!).(12-6!)

²C₆ = (12!)/(6!).(6!)<span>

</span>¹²C<span>₆</span> = 924 Ways
