Answer:

Step-by-step explanation:

m∠1 = x

m∠2 = 3x

m∠3 = ( \frac{1}{3} )(3x) = x

x + 3x +x = 180°

x = 36°

m∠1 = 36°

m∠2 = 108°

m∠3 = 36°

You can set it up as an equation:

Based on the information from Harper's Index, 37 out of 100 adult Americans who did not attend college believe in extraterrestri
vazorg [7]

Answer: Yes, this indicate the  proportion of adult americans that attended college and believe in extraterrestrials is higher than the proportion that did not attend college.

Step-by-step explanation:

Since we have given that

Hypothesis:

H_0:p_1=p_2\\\\H_a:p_1>p_2

n₁ = 100

x₁ = 37

So, p_1=\dfrac{x_1}{n_1}=\dfrac{37}{100}=0.37

n₂ = 100

x₂ =47

So, p_2=\dfrac{47}{100}=0.47

At 0.01 level of significance, z = 2.33

So, test statistic value would be

z=\dfrac{p_1-p_2}{\sqrt{\dfrac{p_1(1-p_1)}{n_1}+\dfrac{p_2(1-p_2)}{n_2}}}\\\\z=\dfrac{0.37-0.47}{\sqrt{\dfrac{0.37\times 0.63}{100}+\dfrac{0.47\times 0.53}{100}}}\\\\z=-1.44

Since, 2.33>-1.44

Hence, we will reject the null hypothesis.

Therefore, Yes, this indicate the  proportion of adult americans that attended college and believe in extraterrestrials is higher than the proportion that did not attend college

Alex needs 80 cm of thread for a sewing project. The thread is on a spool with a circumference of 10 cm. How many times must ale
Mrrafil [7]

<u>Answer:</u>

If the spool has 10 cm of circumference or perimeter, this means that 10 cm of thread fits the whole circumference of the spool, which also means that

<h2>1 unwind is equivalent to 10 cm of thread. </h2>

Then, we have to make the following question:

If 10 cm of thread is equivalent to 1 unwind, to how many unwinds is equivalent 80 cm of thread?

If we want to know how many time does Alex need to unwind the spool, we can use the following relation also called the <u>Rule of Three: </u>

<u> </u>

10 cm----1 unwind

80 cm----X unwinds

X=\frac{80cm(1unwind)}{10cm}

X=8unwinds

The answer is:

Alex must unwind the spool 8 times in order to get 80 cm of thread
