Each of the ten letters in ``mathcounts'' is written on its own square tile and placed in a bag. what is the probability that a tile randomly selected from the bag will have a letter on it that is in the word ``teach''? express your answer as a common fraction.

First, see how many letters in MATHCOUNTS are also in TEACH.

M no

A  yes

T  yes

H yes

C yes

O  no

U no

N no

T  yes

S  no

 That is 5 out of the 10 letters.

so

1/2

Step-by-step explanation:

This is the answer because:

1) In TEACH, there are 5 letters that are in MATHCOUNTS because they are T, E, C, H. However, the T appears two times in MATHCOUNTS which makes it 5 times

2) MATHCOUNTS is 10 letters

3) Therefore, the probability is 5/10 which is 1/2

The answer is 1/2.

Hope this helps!

what does x eaqual

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
