Find x and y. Give reasons to justify your solution

Mathematics
2 answers:
Luda [366]3 years ago
8 0

Step-by-step explanation:

27 + 3y = 90

3y = 90 - 27

y = 21

27 + (21×3) + x + 8x + 18 = 180 ( angles on a straight line sum up to 180)

9x + 108 = 180

9x = 180 - 108

9x = 72

x = 72/9

x = 8 degrees

Answer:

Y=21

X=8

Step-by-step explanation:

In the middle there is a right angle

therefore 27 +3y=90

Y will be 21

Then x+27+63+8x+18=180

x=8

Hence 8+27+3(21)+8(8)+18=180

In a group of 40 people, 35% have never been abroad. Two people are selected at random without replacement and are asked about t
Alisiya [41]

Answer:

\frac{7}{60}

Step-by-step explanation:

Given that in a group of 40 people, 35% have never been abroad. Two people are selected at random without replacement and are asked about their past travel experience.

Since the two are drawn without replacement the first trial affects the second trial.  In other words, each trial is not independent of the other.

a) Hence this cannot be binomial experiment.  The reason is p=probability for each trial is not constant as first draw affect the probability for Ii draw

b) The probability that in a random sample of 2, no one has been abroad

=Prob of selecting both people from the group where no one has been abroad

We have in the group 35% i.e. 14 people never been to abroad

So required probability = Prob of selecting both from 14 people

=\frac{14C2}{40C2} \\=\frac{14*13}{40*39} \\=\frac{7}{60}

What is4-8a=4(5-3a)​
kenny6666 [7]

Answer:

a=4

Step-by-step explanation:

<u>Question: 4-8a=4(5-3a)</u>

<u />

1) Distribute 4 to 5 and -3a:

4-8a=20-12a

2) Add 12a to both sides:

4+4a=20

3) Subtract 4 from both sides:

4a=16

4) Divide both sides by 4:

a=4

Footnotes:

- The <em>Distributive</em> property says a(b+c)=ab+ac
