Why might algebra tiles not be a good tool to use to factor x² + 18x +80

Mathematics
1 answer:
anyanavicka [17]4 years ago
6 0

Answer:

Algebra tiles would not be a good tool to use to factor because you would need to drag an x-squared tile, 18 x-tiles, and 80 plus tiles and  it would take a lot of time to drag that many tiles on the board and there might not be enough space to hold all of them. and do u have time to drag 80 tiles? lol

Hiii!! please help, i don’t understand this question at all!! :(( ASAP :(

The answer is no!

<em>Mutually Exclusive </em>means both events (being female and preferring chocolate) <u>cannot occur at the same time!</u>

We know this is false because on<u> the graph it proves that some females like chocolate! </u>

An example of a Mutually Exclusive event is ( being male and female )

this <u>can't occur!</u>

______________________________

Find the probability that the person is female OR likes chocolate. The word "or" is important - it changes how we do the problem.

Let's <u>add </u>the total amount of people who like chocolate and who are female...

33 + 22 = 55

but we must <u>subtract 15</u> so we <u>won't double count </u>the girls who like chocolate!

40 / (total people)

40 / 50 = 0.80

The probabilty that some is female OR likes chocolate is 80%

I hope I helped :)
